WHY INSPECTION:

Accurate site information is essential for successful offshore positioning.

An exposed cable or a free-span pipeline can easily result in a costly breakage, so Subsea Hundred Global provides a range of suitable methods for conducting route inspections.

Combined with time series analysis, we can visually demonstrate protection requirements due to currents, tides and movement of sediment.

We deploy specialized equipment such as ROVs for detecting, tracking, and mapping using Multi-bean, Side Scan Sonar and under-water videos to follow the route as accordingly and a remotely operated crawler for shallow water environment.

Subsea Hundred Global carries out pipeline inspection surveys to detect free-spans, damage, defects, leaks, erosion or pipeline movement, require innovative technology and experience.


INSTALLATION, REPAIRS & MAINTENACE (IRM) & INSPECTION

REAL TIME MAGNETOMETER DATA ACQUSITION WITH ALTIMETER DISPLAY

Detailed corridor mapping provides the essential raw data for the

design and installation of sub-sea linear structures, such as oil and gas

pipelines, flow lines and umbilical.

Detailed corridor mapping provides the essential raw data for the design and

installation of sub-sea linear structures, such as oil and gas pipelines, flow lines

and umbilical.

Seabed sampling and testing tools - such as grab samplers, vibro-corers and

Cone Penetrometer Testing (CPT) units - can be combined with high resolution

seismic and geophysical data to provide accurate information on the structure

of the seabed. This data is essential for providing a correctly engineered

design that avoids the often-considerable costs associated with over-

engineering for uncertainties.

GEOPHYSICAL ENGINEERING SURVEY


Subsea Hundred Global offers experience engineering surveyors and ROV techs/Pilots from Pipe-Laying to Dive Support operations utilizing the services of a Remotely Operated Vehicle (ROV) and Dynamic Positioning System to ensure that the client’s specifications are achieved.

Accurate site information is essential for successful offshore positioning.Our integrated survey support service uses state-of-the-art construction support vessels with integrated ROVs, ideally suited for pipe lay operations.

Lay barge positioning and remote monitoring of anchor drop locations.Pipeline touchdown monitoring.Pipeline trench profiling for buried lines.Positioning of mattresses for pipeline crossings.Sonar monitoring of pipeline crossings during lay operations.

PIPE LAY SUPPORT SERVICES

- Cloud extruded to 3D Mesh.- Curvature.- Lateral Distance.- Quantification of distances, angles and heights is straightforward.

- ALLOWS FOR MORE IN-DEPTH INVESTIGATION WITHOUT THE NEED TO RECOVER TO SURFACE- ACTIONABLE PLANNING FOR CORRECTIVE STEPS

- Over 500 metrologies ranging from 1.5m to 110m in length- Common distance 20m-35m

- 180 individual offshore projects ranging from 9m to 4000m water depths- Average metrology collection time: 3 hours (Single metrology consists of two scan positions)- Value goes beyond just a single measurement

TRACK RECORD


We work closely with our clients to establish the parameters and objectives of their

projects, also contributing vast international experience of IRM (Inspection, Repairs & Maintenance) and decommissioning projects.

We combine this with pioneering technological innovations and substantial in-house

resources. These include our world class subsea acoustic pipeline inspection services,

with the latest generation of ROTV. However, our Risk Based Inspection methods, are

designed to increase uptime, reduce maintenance costs and further protect the environment.

Our aim is to provide a wholly integrated set of disciplines capable of performing the

most challenging of remote inspection and intervention techniques with precise

positioning, latest inspection technology and modeling services.

Our construction support services are designed to address marine installation,

construction and maintenance activities across the entire field.

We provide precise positioning, survey support and monitoring during the tow-out of

structures and pre-fabricated pipeline bundles; the installation of platforms and

jackets; the placement of subsea infrastructure and the trenching of pipelines and

cables.
