1 Introduction
1.1 Project Background and Description
Oriel Windfarm Limited (Oriel) is an Irish renewable energy company that has
been developing the proposed Oriel Wind Farm, which is located offshore in the
North West Irish Sea, 22km off the coast of Dundalk, County Louth. The
development will include an offshore substation and interlinking cabling between
the turbines and the substation and between the substation to the shore.
Oriel was granted a Foreshore Licence in October 2005 from the then DCMNR,
giving permission to carry out a technical work plan to investigate the suitability
of an area to the East of Dundalk Bay for the construction of an offshore wind
farm. This included geotechnical site investigation, an engineering assessment and
the completion of an Environmental Impact Statement (EIS), and Natura Impact
Statement (NIS).
Following the completion of this work, Oriel applied for a Foreshore Lease in
February 2007, for permission to construct an offshore wind farm of up to
330MW potential within the surveyed area. This application is pending. For a
number of reasons, the development of the project was delayed, however, recent
policy announcements the project has been reignited. Oriel has introduced
Parkwind NV as a strategic shareholder.
Oriel now need to initiate a set of surveys (both onshore and offshore) to update
and complete the planning application and the environmental assessments
previously undertaken.
This document forms part of a Foreshore Licence Application to the Department
of Housing, Planning and Local Government seeking permission to undertake
marine survey works within the proposed development site to support the Oriel
Wind Farm project. These surveys will include the acquisition of updated baseline
environmental data and updated seabed assessments, to establish the optimum
design parameters for the wind farm and to enable the preparation of an updated
Environmental Impact Assessment Report and Natura Impact Assessment. The
scope and methodology of the works are described in this document.
1.2 Marine Surveys
Oriel intend to carry out geophysical, geotechnical, ecological and metocean
marine surveys of the proposed development area. The objective of these site
investigation works is to build upon information gathered in previous surveys by:
• Confirming the geological/geophysical model of the site,
• Determining the vertical and lateral variation in seabed conditions,
• Providing the relevant geotechnical data for the design of the offshore wind
farm, including description and index classification, strength parameters,
deformation parameters, permeability and in-situ stress conditions.

• Updating the geological desk study and,
• Providing a detailed geological model of the site.
1.3 Schedule
It is anticipated that the survey works will commence in early 2019 subject to
approval of the Foreshore Licence Application, appointment of a suitable
contractor, availability of vessels and suitable weather conditions. In order to
allow for unforeseen delays we seek approval of a Foreshore Licence for a period
until 31 December 2019.

2 Description of the Proposed Survey Works
2.1 Survey Vessels
The marine survey works will be carried out by a dedicated marine spread,
suitable for the scope of work required, the water depth and the anticipated
conditions of the survey area and the transit routes. The exact equipment to be
used will be confirmed following a tender process to procure the site investigation
contractor.
It is anticipated that two survey vessels will be required to complete the works:
• A larger vessel suitable for offshore site investigation;
• A smaller vessel suitable for nearshore site investigation (in more shallow
waters).
These vessels will be comparable to those typically used in the industry for
carrying out similar technical work and will possess all relevant classification
certificates.
The vessels will conform to the following minimum requirements as appropriate:
1. Station-keeping and sea keeping capabilities required by the specified work
at the proposed time of year; the appointed contractor may provide
supplemental tug assistance if such assistance benefits the operation;
2. Endurance (e.g. fuel, water, stores, etc.) to undertake the required survey
works;
3. Staffing to allow all planned work to be carried out as a continuous
operation (on a 24 hour per day basis for the offshore activities and on a 12
hour per day basis for the inshore activities);
4. Equipment and spares with necessary tools for all specified works;
5. Appropriate accommodation and messing facilities on board;
6. Adequate soil laboratory testing facility.
The vessels used for the surveys will be sound and capable of remaining safely at
sea for a minimum of thirty (30) days under weather conditions typically
encountered in the marine survey area at the time of year that the operations are to
take place. The appointed contractor will be responsible for all shipboard systems
and equipment calibration and re-calibration, including spares. For every 30 days
of operations the vessels will accrue one day of maintenance time.
Vessels shall have breadth and draft of suitable proportions to provide adequate
stability for the duration of the intended operation. The vessels shall be capable of
passage speeds in excess of ten (10) knots and extended survey operations at
speeds less than two (2) knots.
In addition to AIS-A and Active Radar Enhancing Systems, the vessel shall have
the following communications equipment as a minimum:

• Multi-channel VHF and HF radio capable of working at all marine frequencies
and with a dual watch facility
• Mobile phone
• Hand-held radios
• Frame and winch for the deployment of equipment and sensors, sized for the
required equipment/sensors loads and pulling force. The winch speed and size
must be compatible with planned surveys.
• Gyrocompass
• SATCOM facilities (phone/fax and e-mail)
• 2 independent DGPS systems, a primary and secondary system (DGPS has a
greater degree of accuracy than GPS)
All survey vessels and marine support vessels will conform to the relevant ISO
and API technical specifications for drilling equipment and will maintain valid
class with the recognised Classification Society.
2.1.1 Offshore Vessel
The survey vessel used for offshore works will be either a jack-up barge or a
Dynamic positioning (DP) vessel.
Jack-up barges utilise a fixed anchoring system in order to maintain the required
position within the site. The vessel consists of a self-elevating platform and
several “legs”, that are deployed to the ocean floor mooring the vessel in place.
The survey works are carried out from the self-elevating platform, which is raised
above the water’s surface. If used, the jack-up barge will meet with the following
minimum requirements:
• The vessel will have at least four mooring points
• The self-elevating platform must be permanently manned (i.e. off-shift
personnel to stay onboard even if the accommodation is not a permanent
equipment of the jack-up);
• The platform must be provided with a class certificate verifying the provision
of adequate safety equipment for the type of vessel and the number of on-
board personnel;
• The platform should be certified in compliance with the MODU Code and the
BWEA guideline;
Unlike jack-up barges, DP vessels maintain station via inputs from satellite DGPS
signals, allowing the vessels to be positioned over any point on the seabed and
maintain position without employing a fixed anchoring system. Using thrusters or
propellers, a DP vessel can maintain position within a 2m to 0.5m window
depending on the sea state/weather conditions and available power. The vessel
may also transit under DP control along a given pre-determined path.
If used, a DP vessel will meet the following minimum requirements:

\\GLOBAL\EUROPE\CORK\JOBS\263000\263904-00\4. INTERNAL\4-04 REPORTS\4-04-03 INFRASTRUCTURE\FORSHORE LICENCE APPLICATION\ISSUE 1\ORIEL WIND FARM
FORESHORE LICENCE ISSUE 1.DOCX
Page 6
• The vessel must be fully equipped with a Class II DP system as a minimum
• Two DP certified operators with the necessary experience must be members of
the crew
The offshore works will be carried out on a 24-hour shift basis, with personnel
working two 12-hour shifts. This will allow the works to be continuous.
2.1.2 Nearshore Vessel
The smaller, nearshore vessel will be used in locations where the water depth is
too shallow for the larger, offshore vessel to carry out the works. This vessel does
not need to have a dynamic positioning system, however must have full DGPS
capability. The vessel is usually held on station by joy-stick control and will
deploy an anchor to assist in maintaining station (depending on sea state and
weather conditions). The smaller vessel will use similar equipment to the larger
vessel to carry out the required survey works.
The nearshore works will be carried out on a 12 hour per day basis, with the
vessel returning to port at the end of each day.
2.1.3 Survey Navigation
All navigation equipment and instrumentation will be calibrated and used
correctly. Calibration and/or verification shall be repeated in the event of any
equipment malfunction, which may nullify earlier calibrations and/or
verifications.
Qualified surveyors will be used to operate the navigation and positioning
equipment continuously throughout the survey while maintaining a continuous log
of all navigation activities throughout the survey.
Sufficient survey and positioning spares and consumables will be provided to
enable the survey to be completed without any degradation of navigation and
positioning quality and effectiveness and without the need to return to port to
acquire additional equipment.
2.2 Geophysical Survey
2.2.1 Scope of Work
The purpose of the geophysical survey is to determine the sediment conditions
within the survey area in order to update the information gathered in previous
survey works. This additional data will be used to better understand the sub-
surface structure, in particular the sub-surface stratigraphy, and to confirm the
bedrock elevation.
The objectives of the geophysical survey are to:
• Produce detailed bathymetric mapping;
• Obtain detailed seabed morphology;

• Identify the nature of the seabed;
• Acquire both shallow and deep geological cross-sections of the wind farm site;
• Confirm the export cable route within the cable route corridor.
The geophysical survey will include bathymetric, side scan sonar, magnetometry
and seismic sounding of the proposed site, as shown in
Figure 1. Details of the exact survey equipment shall be made available prior to
commencement of the works; however, it is envisaged that the geophysical data
acquisition will involve the following acoustic-based techniques:
• Multibeam Echosounder (MBES) system for detailed bathymetric mapping;
• Side Scan Sonar for detailed seabed morphology and seafloor mapping;
Magnetometer for detecting geomorphological anomalies and ferrous
obstructions;
• Sub-bottom Profiling (SBP), both single and multi-sourcings, to identify and
characterise the layers of sediment/rock underneath the seafloor along the
cable route corridor.
• Ultra-high-resolution multi-channel seismic (UHRS) to identify and
characterise the layers of sediment/rock underneath the seafloor within the
windfarm site.
The Contractor appointed will be responsible for performing transects with a total
length of circa 84km and a distance of 1km between each transect. The seismic
source shall detect the geological strata to a depth of 40m bsb min. The transects
will be located within the survey area shown in Figure 1 above.

2.2.1.1 Multibeam Echosounder (MBES)
The MBES system will be used to provide detailed bathymetric mapping
throughout the survey area. An MBES is a type of sonar (acoustic surveying) used
in seabed mapping wherein acoustic waves are used to indicate depth-to-seabed.
The device is typically affixed to a vessel’s hull or towed in its wake. The process
is non-intrusive, and the device will not make contact with the seabed at any
point. The Kongsberg EM710 may be taken as an indicative example of a MBES
system to be used in the completion of these works and datasheet for the
Kongsberg EM710 is included in Appendix B. The equipment will operate within
a frequency range of 300-500kHz with sound pressure levels in the range of 200-
228dB re1µPa at 1 metre range.
2.2.1.2 Side Scan Sonar
The side scan sonar will be used to achieve detailed seabed morphology and
seafloor mapping of the survey area. The survey is carried out using a sonar
device attached to a vessel that emits fan-shaped pulse down towards the sea floor
across a wide-angle perpendicular to the path of the sensor through the water. The
intensity of the acoustic reflections from the seafloor of this fan shaped beam is
recorded in a series of cross-track slices.
When stitched together along the direction of motion, these slices form an image
of the sea bottom within the swath (coverage width) of the beam. The equipment
will operate within a frequency range of 100-500kHZ with source levels at 235dB
re 1µPa at 1 metre range.
2.2.1.3 Magnetometer
A magnetometer detects ferrous objects and as such is used to locate and identify
ferrous objects on or buried in the seabed within the range of the magnetometer.
The device precisely measures the earth’s magnetic field and detects any
anomalies, which represent ferrous objects such as lost anchors, sunken ships and
buried piped. The magnetometer is typically towed behind a survey vessel or
affixed to a vessel’s hull. The process is non-intrusive, and the device will not
make any physical contact with the seabed at any point. The G-882 Marine
Magnetometer may be taken as an indicative example and datasheet for this
device in included in Appendix B.
2.2.1.4 Sub-Bottom Profiler (SBP)
The SBP will be used along the cable route corridor only. This device uses
reflection seismology to give a 2D image of the sub-seabed geology. It is typically
towed behind the vessel during survey works or affixed to the vessel’s hull. The
process is non-intrusive, and the device will not make any physical contact with
the seabed at any point. The Innomar SES-2000 Quattro Parametric SubBottom
Profiler may be taken as an indicative example and the datasheet for this device is
included in Appendix B. The shallow sub-bottom profiler system will be used
within the cable route corridor and will have the following general specifications:

• Fundamental frequency between 2kHz and 20kHz
• A vertical resolution better than 0.2 metres
• Penetration of 5 metres
The profiler will be supplied with the following recorders and peripheral
processing equipment:
• Fire control unit
• Time varied gain
• Swell filter
• Bandpass or Time Varying Filters (TVF)
2.2.1.5 Ultra-high-resolution multi-channel seismic (UHRS)
The UHRS will be used within the windfarm site only, commonly used variants of
this technology are known as Sparkers and Boomers. It will have the following
characteristics as a minimum:
• repeatable source,
• fundamental frequency between 1kHz and 3.5kHz,
• broadband width in excess of 2.5kHz at -10db,
• vertical resolution better than 0.5 metres,
• penetration 50 metres,
• variable energy levels 100-1000 Joules,
• record length suitable for the maximum depth required (250ms),
• sampling rate 0.25ms.
A multi-channel hydrophone streamer shall be supplied. The streamer should be
neutrally buoyant or controlled, well maintained and free of air bubbles. The
hydrophone should have a response appropriate to the source used but should
generally have a flat response between 500Hz and 10kHz. The streamer should
have at least 16 channels and be 50m long.
Tail buoy with a radar reflector shall be used. A means of detecting the feather
angle shall be available and recorded at regular intervals along the line. Feather
angles for a streamer of this length (120m) will not exceed 8 degrees. Should the
vessel configuration dictate that the use of a trail buoy is not a suitable option,
compass birds shall be used instead or in addition.
The cable shall have no more than 2 dead channels – these shall not be
consecutive or within the first 5 channels of the streamer.
The UHRS should, as a minimum, be supplied with the following record and
processing facilities:
• Online QC stack

2.3 Geotechnical Survey
2.3.1 Scope of Work
The purpose of the geotechnical survey is to provide relevant information about
the soil to a depth below which possible existence of weak formations will not
influence the safety or performance of the wind turbine and its support structure.
The geotechnical survey will include up to 10 geotechnical boreholes within the
proposed windfarm site and 13 cores within the cable route corridor.
Figure 2 below shows the locations where these works will take place. Drawing
number FL005 provides a more detailed overview of the geotechnical works.

FORESHORE LICENCE ISSUE 1.DOCX
Page 12
Figure 2 and drawing number FL005 show the locations of the boreholes within
the windfarm site.
The equipment used to drill the boreholes will follow the ISO and API technical
specifications for drilling equipment and at a minimum will have:
• A heave motion compensator system on board (seabed frame and/or drill
string) with a minimum heave compensation of 1.5m;
• Capability of mud production to different densities (when mud production is
required for the works). The mud shall be water or bio-degradable organic
polymer;
The boring log, a detailed description of the soil types, and the in situ geotechnical
properties determined for the boreholes will be documented to characterise the
strata.
Coring and sampling shall be done in general accordance with EN ISO22475-1.
Rotary coring equipment, such as Geobor-S is expected to be utilised.
In situ testing shall include the option of either down-hole wireline piezocone
penetration testing (PCPT) associated to PS logging or down-hole wireline
seismic cone testing (SCPT) over full length of borehole.
Alternate sampling and PCPT/SCPT shall be carried out throughout the whole
borehole depth.
The boreholes are to be advanced by alternating PCPT/SCPT and push/core
sampling; requirements will depend on the material type encountered. Within a
granular deposit, the boreholes are to be advanced by alternating PCPT/SCPT and
push sample. Where the sample recovery is poor using the push sampler, a
hammer sampler shall be used instead. Blow counts measured during hammer
sampling shall be recorded and presented on the Borehole Logs. Within the
cohesive deposits, the boreholes are to be advanced by PCPT/SCPT followed by
two push samples (repeat cycle). Rotary coring may be used instead of push
sampling in suitable materials, in which case the CPT and cores shall be
alternated.
The samples/cores shall be recovered in liners or in Shelby tubes for all soil types
and the appropriate technique should be selected to minimise soil disturbance and
maximize recovery.
SCPT tests shall be executed at a minimum of four of the locations, which will be
confirmed following the results of the geophysical survey. Two seismic
measurements shall be carried out during each SCPT stroke at a depth interval of
1m; the envisaged volume is 40-60 SCPT tests in total.
2.3.3 Vibrocoring/Gravity Coring
The appointed contractor will be required to carry out 13 vibrocores/gravity cores
within the export cable route corridor as shown in Figure 2. The cores will be
carried out along the line of the cable route which is still to be defined. Drawing
number FL005 shows an indicative line for the cores.

Vibrocoring is performed where cohesionless soil is expected. The rig will be
fitted with a PVC liner, core catcher and cutting shoe. The vibrocorer is lowered
onto the seabed, position and depth are noted, after which the vibrocoring process
is started. Upon refusal or at target depth, the stop condition is recorded and the
vibrocorer is recovered on deck where the recovery rate is measured. If required, a
core catcher can be used to prevent the sample dropping out of the PVC liner.
A cap must be fitted to the bottom end of the core and affixed with electrical tape.
The core is cut into approximate 1 metre length sections from top and capped as
well. All caps will be sealed with tape. All cores are examined and tested offshore
before any sealing of the sample. Soil found in the vibrocoring shoe is stored in a
bag.
Gravity core (wireline self-weight penetration sampler) is performed where
cohesive soil is expected. The rig is equipped with a PVC liner. The gravity corer
is lowered on the seabed and penetrates in the seabed under its own weight. Upon
refusal or at target depth, the gravity core is recovered on deck where the recovery
rate is measured.
A cap must be fitted to the bottom end of the core and affixed with electrical tape.
The core is cut into approximate 1 metre length sections from top and capped as
well. All caps will be sealed with tape. All cores are examined and tested offshore
before any sealing of samples.
2.4 Ecological Survey
2.4.1 Scope of Work
The purpose of the ecological survey is to update the baseline environmental data
collected from previous ecological surveys. This data will primarily be used to
inform the environmental impact assessment (EIA), by describing the
environmental conditions within the site, and subsequently developing appropriate
mitigation measures for any potential environmental impacts. The ecological
scope of work will include a marine mammal survey and a benthic survey.
The marine mammal survey will be undertaken by the on-board Marine Mammal
Observer. Three to four CPOD’s may also be installed for the purpose of acoustic
monitoring on marine mammal activity within the wind farm area. This will be
supplemented by the vessel-based sighting surveys.
The benthic survey will be used for the collection of sediment sample for analysis
for benthic infauna, particle size, total organic carbon and anthropogenic
contaminants. Benthic ecological assessments will be carried out using drop down
cameras and grab samples. It is estimated that 10 Benthic stations will be
examined for fauna and sediment. One grab will be taken to collect data on the
fauna and a second to obtain a sample for sediment analysis. Grab samples are
similar to grab buckets on land and tend to be either hydraulically or manually
operated. There are many different tools used to recover samples; the method used
will depend on the water depth, currents and sample size required. Typical tools
include a Van Veen type grab sampler.

2.5 Metocean Survey
2.5.1 Scope of Work
The purpose of the metocean survey is to obtain site specific atmospheric, wave
and wind data at the 10m and 120m water levels over a minimum period of 12
months. All metocean survey works will occur at one location within the marine
survey area which will be determined following the appointment of a suitable
contractor.
The data will be collected via a floating weather station, which will include a
wave rider and a wind measurement LiDAR current profiler. The wave rider will
be used to collect wave height and current data across the site, while the LiDAR
system will be used to measure the wind characteristics within the site.

4 Consultation with Third Parties
Oriel undertook an extensive public consultation campaign during the original
Lease application process for the project in 2006 and 2007, to ensure that all
members of the public and the many interested and relevant bodies were kept
fully informed of its proposals. The following actions were undertaken:
1. Statutory consultation was undertaken with a list of key stakeholders as part
of the EIA scoping process and during the formal assessment phase after an
EIA was submitted.
2. Over 360 consultees including statutory bodies, local and national
community groups and individuals were contacted during the original EIA
preparation process, with follow up meetings held with 90 of these.
3. A public information office was also in the Renewable Energy Centre at
Dundalk Institute of Technology throughout the EIA preparation and
decision phase.
4. During the 2-month public consultation phase following the submission of
the EIA all application documents were made available at Garda stations,
council offices and Libraries around the coast from Newcastle Co. Down to
Drogheda Co. Louth. The EIS was also made available for download on the
project website.
Oriel propose to roll out an extensive stakeholder identification and consultation
plan linked to the stages of the consent process. This will include formal
consultation to comply with legislative requirements and additional engagement
with stakeholder groups. Oriel’s intention is to ensure that all members of the
public and the many interest groups and relevant bodies are kept fully informed
and engaged during the project assessment and consents processes.
Local groups and associations will be contacted during each phase of the project
consent process to provide information on the latest project developments and to
allow for opportunities to participate in the consent process and provide feedback
on relevant issues of concern. Meetings will be arranged with these groups on
request. A series of public open days will be scheduled at locations around the
coast to coincide with key project milestones.
Oriel undertook extensive consultation with CRU and the Louth County Council
during the original Lease application process for the project during 2006 and
2007. Oriel intend to undertake similar consultations linked to the stages of the
consent process.
Oriel undertook extensive consultation with all relevant authorities during the
original Lease application process for the project during 2006 and 2007. Oriel

From: Marie Murphy [mailto:[email protected]] Sent: 21 September 2018 12:20 To: Manager Dau Cc: Garrett Connell; Michael Daly Subject: Oriel Windfarm, Co. Louth
To whom it may concern
We act on behalf of Oriel Windfarm Limited (Oriel, an Irish renewable energy company
which has been developing the proposed Oriel offshore wind farm located in the North West
Irish Sea, 22km off the coast of Dundalk, County Louth. Oriel was granted a Foreshore
Licence in October 2005 from the then DCMNR, giving permission to carry out a technical
work plan to investigate the suitability of an area to the East of Dundalk Bay for the
construction of an offshore wind farm. This included geotechnical site investigation, an
engineering assessment and the completion of an Environmental Impact Statement (EIS), and
Natura Impact Statement (NIS). Following the completion of this work Oriel applied for a
Foreshore Lease to construct an offshore generating station in February 2007. In Autumn
2008 the MLVC made a recommendation to grant a lease. Due to government policy
changes the project was delayed however it is now coming back on stream.
We are conscious of the time lapse since the previous investigations and so wish
to undertake a new set of surveys which will comprise of geophysical, environmental,
metocean and geotechnical marine surveys of the marine cable route corridor and the
windfarm site.
The surveys are intended to aid the design by improving the geological and geotechnical
understanding of the site. The data would also be used to inform environmental appraisals by
providing information on the current situation and allowing impacts to be predicted and
subsequently, appropriate mitigation to be developed.
We will be submitting an application fora foreshore licence for the SI, including an AA
Screening shortly.
We are seeking input or comment from the DAU in respect of the proposals as outlined. In
particular, if DAU has any specific requirements in respect of the initial surveys, which it is
hoped to undertake early in 2019, then we would be grateful if a response could be provided
as soon as possible.
Should you have any queries, please do not hesitate to contact me.

Re: Oriel Windfarm, located in the North West Irish Sea, 22km off the coast of
Dundalk, County Louth
A chara
On behalf of the Department of Culture, Heritage and the Gaeltacht, I refer to
correspondence received in connection with the above.
Outlined below are heritage-related observations/recommendations of the Department
under the stated heading(s).
Nature Conservation
This Department notes that the applicant previously had a foreshore lease in 2008 for an
offshore windfarm at Oriel which did not progress, and, due to the lapse in time, now
wishes to conduct offshore site investigation work to an area east of Dundalk Bay and will
be applying for a foreshore licence for same with an AA screening. Please find below
comments on marine, birds, and appropriate assessment issues that may assist.
Marine
The proposed development may be within and adjacent to Dundalk Bay cSAC (site code:
IE000455). It would also be within and adjacent to Dundalk Bay SPA (site code: 004026).
As noted in previous correspondence these sites are designated for a range of habitats,
communities and species. In addition, there are a number of other designations within a
distance of the proposed development.
According to Article 6(3) of Council Directive (92/43/EEC) (the Habitats Directive) any plan
or project not directly connected with or necessary to the management of the site but likely
to have a significant effect thereon, either individually or in combination with other plans or
…..
2
projects, shall be subject to appropriate assessment of its implications for the site in view of
the site's conservation objectives. The provisions of this article have been transposed into
the Irish Statute by Regulation 42 of the European Communities (Birds and Natural
Habitats) Regulations (SI 477 of 2011).
It must be noted that all cetaceans are listed under Annex IV (including those in Annex II) of
Council Directive 92/43/EEC (the Habitats Directive). Accordingly, under Article 12 of that
Directive, it is an offence to deliberately capture, disturb or kill a cetacean or take actions
that result in deterioration or destruction of their breeding sites or resting places. This has
been transposed into Irish Law by Regulation 51 of the European Communities (Birds and
Natural Habitats) Regulations. Introduction of certain sound sources into the marine
environment, as may result from construction or surveys (e.g. geophysical survey) over the
foreshore, have the potential to cause injury and possibly mortality in these species. All
marine mammals are protected wild animals under the Fifth Schedule, which includes all
cetacean and seal species, of the Wildlife Act (39 of 1976) and Amendments. Under
Section 23 (as amended in 2000), it is an offence to kill, injure or willfully interfere with or
destroy the breeding place or resting place of any protected wild animal.
Details of the site synopses and qualifying interests of Natura sites are available on
http://www.npws.ie/protected-sites. Further information related to site specific conservation
objectives are also available at this location by entering the Site Code (as in first
paragraph). Additional supporting information and referenced publications are also
available to download from this resource. Site boundaries and mapped habitat resources
are available to download from http://www.npws.ie/maps-and-data. The proponent should
pay particular attention to the conservation objectives framed around the Area, Range,
Structure & Function and Future Prospects for each qualifying interest. It might also be
useful to review recent case law surrounding the development of Article 6 of the Habitats
Directive and in particular the application of conservation objectives for Natura sites.
In order to fulfil the Article 6 legal requirements the following information should be supplied
within the application in relation to Annex I habitats:
A. Full description of proposed operation/activity
A full and finalised description of the proposed methodology including the likely time-
scale of works. It is not currently clear what level of interaction would occur within
Dundalk Bay SAC/SPA.
Are there similar operations/activities already in the locality? If existing
operations/activities occur adjacently then a justification for additional facilities should
be included. Would the proposed works act in conjunction with any existing or planned
developments?
The facilities or licensing to be put in place to cope with both biological and industrial
waste (e.g. extracted drill materials, etc.) generated during the proposed survey work
…..
3
should be detailed. Detailed contingency plans sufficient to address potential negative
interactions with the marine environment e.g. oil spills.
B. Baseline description of relevant environment
A description of the biological environment over which the activity would impact,
including the marine and terrestrial flora and fauna, must be included if work is
envisaged with Dundalk Bay SAC.
Consideration should be given to whether the likely works would result in disturbance or
loss to Annex I habitats. Any loss or interruption of normal processes must be
quantified relative to the entire designated area not just within the direct footprint of
development.
In addition to the information related to the Annex I habitats the proponent should also
evaluate whether the operations would have a potential to interact with marine mammals.
The proponent must ensure that the survey operations are compliant with “Guidance to
Manage the Risk to Marine Mammals from Man-made Sound Sources in Irish Waters”. The
latest version of this document was published in January 2014 and is available to download
from http://www.npws.ie/marine/bestpracticeguidelines/.
Birds
No map has been supplied, but it seems likely that the proposed site investigations could
be within and adjacent to Dundalk Bay SPA Special Protection Areas (SPA) (site code:
004026) designated under the EC Birds Directive (Directive 2009/147 EC). In order carry
out an AA screening and to assess the likelihood of any impacts, including ex-situ impacts,
on the SPA it would be necessary to have data on bird usage in the vicinity of the proposed
site investigations.
Where bird surveys are necessary, surveys should be carried out by suitably qualified
persons at an appropriate time of the year depending on the species being surveyed for.
The AA screening should include the results of the surveys, and detail the survey
methodology and timing of such surveys. It is expected by this Department that in any
survey methodology used that best practice will be adhered to and, if necessary, non Irish
methodology adapted for the Irish situation.
Baseline Data
With regard to the scope of baseline data, details of designated sites can be found at
www.npws.ie/ . For flora and fauna the data of the National Parks and Wildlife Service
(NPWS) should be consulted at www.npws.ie/ . Where further detail is required on any
information on the website, a data request form should be submitted. This can be found at
www.npws.ie/sites/default/files/general/Data%20request%20form.doc. Further information
may be found at http://dahg.maps.arcgis.com/home/index.html. Other sources of
information relating to habitats and species include that of the National Biodiversity Data
…..
4
Centre (www.biodiversityireland.ie), Inland Fisheries Ireland (www.fisheriesireland.ie),
BirdWatch Ireland (www.birdwatchireland.ie) and Bat Conservation Ireland
(www.batconservationireland.org). Data may also exist at a County level within the
Planning Authority.
Complete details of site investigations methodology
Complete details of the site investigations need to be provided in order to allow an
adequate assessment to be undertaken. If necessary something similar to an outline
construction management plan (CMP) may be necessary.
Appropriate Assessment (AA)
Guidance
Guidance on AA is available in the Departmental guidance document on Appropriate
Assessment, which is available on the NPWS web site at:
www.npws.ie/sites/default/files/publications/pdf/NPWS_2009_AA_Guidance.pdf
and in the EU Commission guidance entitled “Assessment of plans and projects
significantly affecting Natura 2000 sites. Methodological guidance on the provisions of
Article 6(3) and (4) of the Habitats Directive 92/43/EEC” which can be downloaded from
http://ec.europa.eu/environment/nature/natura2000/management/docs/art6/natura_2000_a
ssess_en.pdf.
However CJEU and Irish case law has clarified some issues and should also be consulted.
Conservation objectives
In order to carry out the appropriate assessment screening, and/or prepare the Natura
Impact Statement (NIS), information about the relevant Natura 2000 sites including their
conservation objectives will need to be collected. Details of designated sites and species
and conservation objectives can be found on www.npws.ie/. Site-specific, as opposed to
generic, conservation objectives are now available for some sites. Each conservation
objective for a qualifying interest (QI) is defined by a list of attributes and targets and are
often supported by further documentation. Where these are not available for a site, an
examination of the attributes that are used to define site-specific conservation objectives for
the same QIs in other sites can be usefully used to ensure the full ecological implications of
a proposal for a site’s conservation objective and its integrity are analysed and assessed.
It is advised, as per the notes and guidelines in the site-specific conservation objectives,
that any reports quoting conservation objectives should give the version number and date,
so that it can be ensured and established that the most up-to-date versions are used in the
preparation of Natura Impact Statements and in undertaking appropriate assessments.

Where further detail is required on any information on the website a data request form
should be submitted. This can be found at:
www.npws.ie/sites/default/files/general/Data%20request%20form.doc.
Cumulative and ex situ impacts
A rule of thumb often used is to include all Natura 2000 sites within a distance of 15 km. It
should be noted however that this will not always be appropriate. In some instances where
there are hydrological connections a whole river catchment or a groundwater aquifer may
need to be included. Similarly where bird flight paths are involved the impact may be on an
SPA more than 15 km away.
Other relevant Local Authorities should be consulted to determine if there are any projects
or plans which, in combination with this proposed development, could impact on any Natura
2000 sites.
The above observations/recommendations are based on the papers submitted to this
Department on a pre-planning basis and are made without prejudice to any observations
that the Minister may make in the context of any consultation arising on foot of any
development application referred to the Minister, by the planning authority/ies, in her role as
statutory consultee under the Planning and Development Act, 2000, as amended.

FUGRO DIGITAL SEISMIC CONE SYSTEMThe seismic cone penetration test (SCPT) provides in-situ seismic wave velocities as well as piezo-cone penetration test (PCPT) parameters.
Seismic wave velocities give high-value
information about in-situ ground
characteristics, such as low-strain shear
modulus for use in earthquake design
studies and analysis of dynamically loaded
foundations.
EQUIPMENT AND SOFTWAREKey components of the Digital Seismic
Cone System are:
■■ Digital seismic cone penetrometer with
two 3-axis receiver set at a fixed
spacing of 0.5 m (downhole mode) and
one 3-axis receiver set (seabed mode)
■■ Seismic source with trigger
■■ Digital seismic trigger module
synchronizing the data recording with
the seismic source activation
EQUIPMENT FLYER
■■ Computer running integrated PCPT
and SCPT data acquisition software.
The signals are digitized inside the
penetrometer, reducing the number of wires
in the cable and reducing noise pickup and
cross talk in (long) cables.
In downhole mode a dual element seismic
penetrometer has the advantage of a single
source activation being recorded at two
depths simultaneously. This enhances
accuracy in depth interval and removes
dependency on source reproducibility.
Offshore operations require use of a
hydraulic underwater Shearwave Hammer
as seismic source. the source is fixed to
the base of the seabed frame and is
remotely operated.

TEST PROCEDUREThe SCPT procedure includes a repeated
sequence of the following steps:
■■ Interrupting the standard CPT
procedure at the desired seismic
test level
■■ Activating the seismic source and
recording of the seismic receiver
signals, if necessary with re-activating
cycles to permit stacking
■■ Optional: data validation by displaying
the preliminary depth profile within the
data acquisition software
■■ Resuming the standard CPT
procedure, repeating the test sequence
as required.
TEST RESULTSPrimary test results consist of seismic wave
traces for, usually multiple, test depths. The
use of data filtering techniques is common.
Data processing includes calculation of
seismic wave velocities, with additional
options such as:
■■ Taking time lag as the time shift of the
maximum cross-correlation of
the signals
■■ Travel path correction based on Snell’s
law of refraction for ground layers
showing abrupt changes in density
or stiffness
■■ Integrated presentation of seismic
parameters and CPT data.

Fugro Tool Data Sheet
Application The calliper is used to measure the diameter of the borehole. It can be used in both open and cased boreholes. This tool is usually deployed before any other tool to check the integrity and condition of the borehole. The 4 arm calliper has 2 pairs of interdependent arms which measure the X and Y diameter of the borehole. This gives a measure of the ovality of the borehole which can indicate differential squeezing of the formation. The tool is normally deployed before any other tools to check the integrity and condition of the borehole. The calliper curves indicate the location of different casing types and breakages, fractures and fissures, and borehole caving and squeezing. It can also be used for the identification of soft and hard formations which can be correlated with other measurements to further refine lithological interpretations. As borehole condition can affect the quality of many other geophysical readings the calliper log is very important for quality control of other survey data and is required for environmental corrections to other measurements.. The curves can also be used to calculate borehole fluid, cement or backfill volumes. Example Log

High Performance Corer - HPCTM
Fugro Alluvial has developed a High Performance CorerTM to cope with the demand for longer sample
recovery in dense granular and stiff cohesive materials.
Application
The HPCTM utilises innovative electric motor technology and
sample barrel design. The new motor technology allows an
optimisation of excitation frequency and vibration amplitude
to suit any particular soil conditions. At it’s most powerful
settings the HPCTM can apply more than twice the power and
five times the vibration amplitude of a standard vibrocorer.
All of this translates into much longer sample recovery.
The HPCTM may also be used with a newly developed low area
ratio sample barrel which minimises the sampling disturbance in
clay soils.

MAIN BENEFITS■■ Constant penetration rate
Constant penetration rate of 20 mm/s
independent from required thrust.
■■ High CPT data quality
No negative effect on CPT data caused
by varying penetration rates.
■■ Compact storing and safe handling
■■ Improved safety, reduced
deployment time
No more manual rod handling, making
the system safer to service and easier
to deploy.
■■ Longer lifetime, less maintenance
The system consist of simple
components making it easy to
maintain. Due to the improved force
transmission, the rods, either coiled or
built from conventional 1m sections,
will have a longer operational lifespan.
Coiled rods can easily been replaced.
FUGRO SEACALF®
MKIV – CONTINUOUS DRIVEThe Fugro SEACALF® MkIV is a novel seabed deployed Cone Penetration Test (CPT) system, employing a coiled push rod and a compact continuous thrust machine.
COMPACT AND EFFICIENT CPT SYSTEMBy using a novel combination of
techniques, the new SEACALF® MkIV
provides higher efficiency, a smaller system
to handle and improved reliability compared
to conventional seabed CPT systems.
This new continuous drive system (CDS)
has been developed to improve reliability, to
ease handling and to reduce build- and
maintenance costs. Special clamping
blocks improve the force transmission to
the rod, resulting in an efficient system with
a push- and pull capacity of 200kN and a
very constant penetration rate, resulting in
higher quality of CPT data. The drive
system consists of simple components,
EQUIPMENT FLYER
making it a reliable system that is small in
volume and easy to maintain.
Traditional seabed CPT systems of this
order typically employ manually assembled
1m push rods. The SEACALF® MkIV can
employ such a conventional rod but can
also be equipped with a coiled push rod.
The coiled rod allows for compact storing
and safe handling and can, thanks to an
advanced straitening- and recoiling device,
be coiled and stored inside a small frame.
The use of a coiled rod eliminates the need
for manual rod handling, it creates a safer
work environment and enables a significant
reduction in deployment time.

piezocone penetrometer is employed, but
other penetrometer sizes can also be used.
Continuous Drive System - Machine
providing thrust to the push rods so that the
required constant rate of penetration is
controlled. The thrust machine provides a
nominal force of 200 kN. Nominal
penetration and retraction rate is 20 mm/s.
Cyclic testing is also possible.
Deployment frame – Frame for mounting
and handling, providing reaction weight for
the thrust machine. Weight and size of the
frame may be adjusted to suit expected soil
conditions, vessel and handling options.
Data acquisition and control system -
Apparatus and software, including sensors,
data transmission apparatus, recording
apparatus and data processing apparatus.
FUTURE DEVELOPMENTSSea trials were successful and indicated
that the requirements set in the original
design philosophy are met. The SEACALF®
MkIV system proved to be efficient and
robust, providing similar or better
performance compared to existing systems.
The current design of the SEACALF® MkIV
mainly focusses on servicing the offshore

Seabed Operation
Fugro performs offshore geotechnical soil investigations and provides consulting and engineering advice.
General description
Fugro gathers high quality soil data with the help of
experienced personnel and state of the art techniques.
With the geotechnical information Fugro consults in
foundation engineering, interpretation, scientific projects
and geohazard advice.
The data is collected in-situ by performing Piezo Cone Penetration
Tests (PCPT), or other probe tests, and by taking (core) samples.
The samples are tested in the laboratory and combined with
the PCPT results, provide a detailed profile describing the soil
characteristics.
Fugro has two distinguished geotechnical investigation methods:
downhole operation and seabed operation. This folder describes
the seabed operation.
Seabed Operation
During seabed deployment operations, PCPT’s and other probe
tests can be performed to a maximum of 40 m below seabed
(bsb), and soil can be sampled to 25 m bsb, depending on the
system and the soil conditions. Seabed operations are well suited
for investigations for shallow foundation types.
A geotechnical site investigation is generally performed from a
specialised geotechnical vessel or a vessel of opportunity such
as a survey or supplier vessel. The vessel is positioned above
the testing location and the seabed unit or sampling system is
deployed with the aid of an A-frame, a crane, through the ship’s
moonpool or with a special deployment structure over the side of
the vessel. After the seabed unit or sampling device is placed on
the seabed, the test is performed and/or a sample is taken. The
approach and programme is adapted to client requirements and
site conditions, such as water depth, heave, current, seabed slope
and weather conditions. Two basic subsystems can be identified
in seabed operation mode: systems using hydraulic thrust and
gravitational systems.
SEACALF®
Markab
Seabed Operation
FUGRO SMARTPIPE®
FUGRO SMARTPIPE® is developed for in-situ testing to model flow
lines and pipe-soil interaction with very soft soils in water depths
to 2,500 m. By reducing uncertainty in pipe-soil interactions,
pipeline design can be more effective, leading to cost reduction
and risk mitigation for the overall project. It is an in-situ testing
system which consists of an instrumented pipe segment. This
pipe segment directly measures the interaction forces and can be
moved in vertical, axial and lateral dimensions. In addition, pore
water pressure is measured at several discrete points along the
underside of the pipe.
The seabed frame is also equipped with a T-bar, mini T-bar,
camera, frame settlement gauge and a roll and pitch sensor. It can
be deployed from a specialised geotechnical vessel or a vessel of
opportunity.
FUGRO SMARTPIPE® is often used in conjunction with
SMARTSURF for investigations on pipeline and cable routes
investigations. Both systems use the same base reaction frame
which is controlled through a combined power and data umbilical
cable, which also is used for hoisting the frame.
Systems using hydraulic thrust
SEACALF®
The SEACALF® system is an electronic testing platform able to
perform continuous PCPT’s and other probe tests to 40 m bsb
in water depths to 2,500 m and is mainly used for geotechnical
site investigation for seabed structures, jack-up rigs, production
platforms and other offshore structures.
The SEACALF® system consists of Fugro’s Seabed Frame (SBF)
with an integrated drive unit. The drive unit uses two or four
hydraulic powered wheels which are pushed against a sounding
rod (string) using hydraulic cylinders. The rod, equipped with a
cone or probe, is pushed into the soil by the rotating wheels at a
controlled rate. If additional thrust is desired, two drive units can
be stacked. Electric power, data and real-time communication are
transmitted via an Underwater Power Cable (UPC) with the vessel.
The SEACALF® system is usually deployed from the moonpool of
the vessel and can also be equipped with additional equipment
such as a camera and a frame settlement gauge.
SEAROBIN®
The SEAROBIN® is a conical lightweight reaction frame, designed
to perform 3 m PCPT’s using a small drive unit. An integrated push
and grab sampler allows soil sampling during the same deployment.
Deployment time is short, thus this system is particularly suited
for investigations involving a high number of test runs, such as for
pipeline and cable routes. The maximum water depth in which the
SEAROBIN® can operate is 2,500 m.
The SEAROBIN® is controlled through a combined power and
data umbilical cable, which also is used for hoisting the frame.
The SEAROBIN® can be deployed from specialised geotechnical
vessels or vessels of opportunity.
SEAROBIN®
Seabed Operation
SMARTSURF
The SMARTSURF is used for geotechnical investigations to 2,500
m water depth. The SMARTSURF can performe PCPT’s and other
probe tests, mini T-bar and take a sample in a single deployment. It
has the same deployment frame as the FUGRO SMARTPIPE® and
a change to SMARTSURF can be quickly made and complement
the data necessary for flow lines and cable routes.
SEASCOUT¹
The SEASCOUT is a lightweight in-situ test system that is primarily
used for cable route investigations. It has a very small, fast deployed
spread and can even be used from a ROV and therefore can test
in hard to reach places, for example underneath an oil platform or
within pipeline trenches.
A 5 cm2 piezo-cone is attached to a coiled rod that is pushed into
the soil with a drive unit to 10 m bsb. The SEASCOUT can be
deployed using an A-frame or crane in 2,500 m water depth.
Roson Seabed system¹
The Roson seabed frame is equipped with one or more stacked
Roson drive units used to perform PCPT’s and other probe tests to
15 m bsb in 500 m water.
Gravitational systems
Fugro uses a range of seabed sampling systems such as corers and
bulk samplers. The sample systems are used to retrieve high quality
and relatively undisturbed samples in very soft to soft soils. Only the
High Performance Corer - HPC™ (Vibrocorer) can be used in harder
soils. Some of the systems are lowered fast on the wire to retrieve
the sample; others have a trigger release mechanism that allows
the corer to free-fall once the corer is suspended a couple of meters
above the seabed. Most of the corers also have a stationary piston
that prevents the sample flush away when the corer is retrieved.
STAtionary Piston Gravity CORer - STACOR®¹
The STACOR® is a piston sample corer able to retrieve, large
diameter (105 mm) and long samples in very soft to soft soils. It
can sample in water depths to 3,000 m and the maximum sample
length is 25 m.
The STACOR® has a trigger release mechanism and is deployed
with a specialised deployment system.
Kulemberg Piston Corer
The Kulemberg Piston Corer can retrieve very soft to soft soil
samples in water depths to 3,000 m. It also has a trigger release
mechanism. The maximum sample length is 6 m. It can be deployed
either from the side or the back of the vessel with an A-frame.
Variable Weight Gravity Corer
The Gravity Corer can retrieve soft to stiff soil samples in water
depths to 3,000 m; the maximum sample length is 6 m. The mass
of the Gravity Corer can be adjusted by adding weight blocks to
the corer for different soil conditions. The tool does not free-fall
but is lowered on a wire and uses the winch speed to penetrate
the seabed. It can be deployed either from the side or the back of
the vessel with an A-frame.

can sample in water depths to 3,000 m and the maximum sample
length is 20 m.
It can be deployed either from the side or the back of the vessel
with an A-frame.
High Performance Corer - HPC™ (Vibrocorer)¹
The HPC™ is a sampling device with an electric motor that creates
vibrations which drives the core barrel into the soil. The working
water depth is 450 m and it can retrieve 6 m samples in stiff,
granular soils.
Box Corer¹
The Seabed Box Corer is a bulk, sampling device for sampling
the seabed top soil. These samples of the very soft, cohesive top
layer are very suitable for sub-sampling, laboratory testing and mini
T-bar testing. A bar with weight blocks pushes a square box into
the ground. When the box corer is lifted, a lid closes below the
sample box.
Grab Sampler
The grab sampler is also a bulk sampler which is triggered when
touching the seabed. Grab samples are disturbed and are used
for examining mineral deposits, aggregate prospecting and
environmental and pre-dredging research. When the sampler is
lifted, the scoops close around the soil.

THE SEABED UNITThe penetration force for this evolution of theSEACALF is provided by the Fugro BLOCK-DRIVE system. The rods are driven from apower pack mounted on the seabed frame. Theframe is 3.4 m high and the base is 3 m x 3 m.It weighs approximately 25 tonnes in air. Forextra reaction this can be increased by theaddition of ballast blocks. The unit can be setup to provide 100 kN (10 tonnes) or 200 kN (20tonnes) of penetration thrust, by using one ortwo block-drives systems.
PERFORMING A TESTAn electronic cone penetrometer, connected toa string of rods, is pushed into the seabed at acontrolled rate. As it penetrates the variationsin cone resistance, sleeve friction and porepressure (or other parameters) are continuouslyrecorded. Signals from the sensors passthrough a control and data transmission moduleon the seabed frame are then transmitted, indigital form, to the surface via a combinedpower and signal umbilical. The results aredisplayed graphically on the monitor andsimultaneously recorded. The operator main-
tains complete control of the seabed unitthrough the computer.
Block-Drive Seacalf CPT
The BLOCK-DRIVE SEACALF is a further development of the SEACALF system, which has beenin use for offshore geotechnical investigations since 1972. It is an underwater rig for performingcontinuous static cone penetration tests (CPT) from the seabed in water depths ranging from 10m to 500 m. Tens of thousands of tests have been performed with the SEACALF to investigatesites for wind-turbines, jackup rigs, production platforms, pipelines and other offshore structures.
BlockDrive.qxd:3D_Mapping_Pro2.qxd 13-10-2008 11:01 Pagina 1
TEST PENETRATIONThe amount of penetration that can be achievedat a specific site depends on upon the soil con-ditions and the available reaction force. In 200kN mode with full ballast, penetration typicallyranges from about 20 m in dense sands andhard gravely clays to between 30 and 60 m insofter ‘normally consolidated’ clays. Any lengthtest rod can be built into the rig prior to deploy-ment. The rod is kept vertical by means of ten-sioned wire connected to the rigging system.
INSTRUMENTATIONStandard instrumentation incorporated on theseabed frame includes a dual axis inclinometerand a water pressure transducer. A CCTV cam-era can be attached to the frame and the sig-nals transmitted via the main umbilical. Thesystem can also be adapted to perform vaneshear tests, plate load tests or push otherinstrumented probes into the seabed including:
• seismic cone • thermal and electrical conductivity cones • full displacement pressuremeter • dilatometer • nuclear density probe • model caisson structures
DEPLOYMENT VESSELSThe BLOCK-DRIVE SEACALF can be used fromany of the Fugro geotechnical drilling ships orcan be modified for deployment from other suit-able vessels. It can be deployed on twin linethrough a moonpool or via crane or A-Frameover the side of the vessel. The system isinstalled on our own specialised geotechnicalinvestigation vessel – the Fugro Commander.

Piezo-cone penetrometer
The Piezo-cone penetrometer: for in-situ geotechnical testing
Introduction
For in-situ geotechnical characterisation of ground con-
ditions, Fugro uses the piezo-cone penetrometer (piezo-
cone) for performing a piezo-cone penetration test (PCPT
or CPTU). Fugro has developed a range of state of the art,
in-house designed and built piezo-cones.
Application
A PCPT involves the measurement of the resistance of the soil to
steady and continuous penetration of the piezo-cone equipped with
internal sensors. The measurements comprise penetration depth,
cone resistance, sleeve friction, pore pressure and inclination from
vertical.
The piezo-cone measures the transient pore pressure generated
during penetration, as well as the hydrostatic pore pressure.
The transient pore pressures can be significant for some low-
permeability soils. Measurement of the dissipation of the transient
pore pressure is feasible during a penetration interruption. The
dissipation measurements permit the estimation of the in-situ
coefficient of consolidation.
These measurements permit high quality interpretation of the
ground conditions, provide a stratigraphic profile and thus an
accurate knowledge of the soil layering which is essential to a
geotechnical study.

Piezo-cone penetrometer
Instrument Details
The basic and most commonly used piezo-cone measures three
parameters: the cone resistance (qc), the sleeve friction (fs) and the
pore pressure (u). The cone and the friction sleeve consist of high-
quality steel that is resistant to corrosion and abrasion. It has a
single pore pressure sensor behind a filter of a porous material
and can be positioned either in the face of the cone (u1), or at the
cylindrical extension of the cone (u2).
The sensors inside the piezo-cone that measure the cone
resistance and sleeve friction consist of load-cell type measuring
transducers (strain gauges) arranged to a subtraction system. This
arrangement permits a stiff penetrometer design.
Test Procedure
A piezo-cone is pushed into the soil using a thrust machine
providing thrust to the push rod(s) so that the required constant
rate of penetration is controlled (20mm/s). The deployment of a
piezo-cone can take place from (1) ground surface and seafloor or
(2) downhole whereby the thrust machine is positioned in the lower
end of drill pipe.
A computer-based data acquisition system provides the link
between the electrical output signals of the piezo-cone sensors
and the digitally recorded data. This data can be acquired real-
time and is shown on a monitor. With other systems (WISON® XP/
Dolphin) the data is stored and linked to the computer after retrieval.
The digital data allows rapid processing of the measurements (qc, fs
and u) and the derivation of PCPT parameters such as total cone
resistance (qt), friction ratio (Rf) and pore pressure ratio (Bq).

Multibeam echo sounderHigh resolution seabed mapping system
EM 710
(855-164939 / Rev.C / June 2006)

System description
System overviewThe EM 710 multibeam echo sounder is a high to very high resolution seabed mapping system capable of meeting all relevant survey standards. The system configuration can be tailored to the user requirements, allowing for choice of beam widths as well as trans-mission modes.
The minimum acquisition depth is from less than 3 m below its transducers, and the maximum acqui-sition depth is approximately 2000 m, somewhat dependant upon array size. Across track coverage (swath width) is up to 5.5 times water depth, to a maximum of more than 2000 m.
Echo sounder modelsThere are three basic versions of the EM 710 system, with different range performances:• EM 710 - Full performance version.• EM 710S - CW pulse forms only.• EM 710RD - Short CW pulse only.
Choice of beamwidthsThe along track beamwidth depends upon the chosen transducer configuration with 0.5, 1 and 2º available as standard. The receive beam width is either 1 or 2º depending on the chosen receive transducer.
Innovative acoustic principlesThe EM 710 operates at sonar frequencies in the 70 to 100 kHz range. The transmit fan is divided into three sectors to maximize range capability, but also to suppress interference from multiples of strong bottom echoes. The sectors are transmitted sequen-tially within each ping, and uses distinct frequencies or waveforms. EM 710S and EM 710RD both use CW pulses of different lengths. The full performance version, EM 710, supports even longer, compressible waveforms (FM sweep).
Fully stabilized and focused beamsThe system applies beam focusing to both transmit and receive beams in order to obtain the maximum resolution also inside the acoustic near-field. During transmission, focusing is applied individually to each transmit sector with a focus point on the range defined by the previous ping, to retain the angular resolution in the near field. Dynamic focusing is applied to all receive beams. The transmit beams are electronically stabilized for roll, pitch and yaw, while the receive beams are stabilized for roll movements.
Controlled, dense and accurate sound-ingsThe beam spacing may be set to be either equiangular or equidistant. The maximum swath coverage may be limited by the operator either in angle or in swath width without reducing the number of beams. A combination of phase and amplitude bottom detection algorithm is used, in order to provide soundings with the best possible accuracy.
The number of beams varies with the beamwidth. The system generates 256 beams/400 soundings per ping for 0.5 and 1º systems, and 128beams/200 soundings for a 2º system.
TransducersThe active elements of the EM 710 transducers are based upon composite ceramics, a design which has several advantages, in particular increased bandwidth and tighter performance tolerances. The transducers are fully watertight units which will give many years of trouble-free operation.
The 1x2º and 2x2º versions can be mounted on a pole for portable deployment, while the larger trans-ducer versions are for permanent mounting; flush with the hull, in a blister or in a gondola construction.
Transceiver UnitThe EM 710 electronics system is a true wideband design. The transmitter circuits are fully programma-ble to support any frequency or pulse form. The use of FM sweep as a pulse form allows for more energy per pulse and thus increased range performance, with-out any sacrifice of range resolution.
The non-saturating and low noise receivers and A/D converters are of floating point type, resulting in a dynamic range of more than 140 dB. The conven-tional TVG compensation is no longer needed.
Filters, correlators and beamformers are fully dig-ital implementations, and the beam forming method is by time delays, to allow for the wide frequency band of the system.
Operator StationThe Operator Station is the HWS high performance dual-processor PC workstation is used as. It is dual bootable to either Linux® or Windows XP®.
The HWS is normally supplied with a 19” industri-alized LCD monitor with a resolution of 1280x1024 pixels. Support for a second monitor is included. A spill-proof US keyboard and a standard optical mouse is normally supplied.

Advanced functions
• Integrated seabed acoustical imaging capability is included as standard. Software to use this data for automatic seabed classifi-cation is available.
• A real time display window for water column backscatter is avail-able. Logging of water column data and of raw stave data (before beamforming) is a system option.
• A high density beam processing mode provides up to 400 or 200 soundings per swath. In order to make the soundings independ-ent, a limited range window is set inside each beam for each sound-ing. In practice this is equivalent to synthetically sharpening the beam width.
• With a 0.5º transmit and 1º receive transducer the system will be able to generate two separate alongtrack swaths per ping. The system produces up to 800 sound-ings per ping in this mode.
• The Operator Station includes the necessary operator controls for setting up and running the system, data logging and system testing.
• The Seafloor Information System (SIS) includes an extensive set of graphical displays for data quality control, as well as system calibration and other tools which are required. SIS supports on-line real-time data cleaning to improve the overall survey effi-ciency.
• Post-processing software for the EM 710 is available from both Kongsberg Maritime and third-party suppliers.

Offshore Testing / Validation
The SEAWATACH Wind LiDAR Buoy has been tested and validated
at the Ijmuiden met mast in Dutch waters. The wind profile data
measured by the SEAWATCH Wind LiDAR Buoy were compared
with data from anemometers at 3 heights mounted on the met
mast and a ZephIR LiDAR, measuring the wind profile above 90
m. An inter-comparison showed almost no bias and a squared
correlation of more than 0.99. The validation test was performed in
close cooperation with DNVGL
