1 OUTLINE DETAILS OF THE LAGGAN-TORMORE DEVELOPMENT PROJECT

1.1 INTRODUCTION TOTAL is planning to develop the Laggan-Tormore fields which are located in UKCS Blocks 206/1 and 205/5 in a water depth of approximately 600 m (see Figure 2). The Laggan gas condensate reserves were first discovered by an exploration well drilled by Shell in 1986. There was no further exploration activity in the block until TOTAL was awarded a license to explore for hydrocarbons following the 16th Licensing Round in 1995. Following this award TOTAL drilled an appraisal well at Laggan in 1996 and a further appraisal well in 2004. The Tormore reservoir was discovered by an exploration well drilled in summer 2007. The Laggan-Tormore Development is located approximately 125 km from the BP operated onshore Sullom Voe Terminal (SVT), 45 km to the north-west of the BP Clair oil field and approximately 90 km to the north-east of the BP Schiehallion/Loyal and BP Foinaven oil fields. TOTAL plans to develop Laggan-Tormore as a subsea development with a tie-back to SVT. Following onshore processing, gas will be exported through a new export pipeline to the FUKA pipeline at MCP-01 and onwards to the St Fergus Terminal. The Laggan-Tormore field development presents several major technical challenges which the project has faced since the outset including:

Marginal nature of the field and distance from market; Deepwater location of the site on the continental slope; Extreme weather conditions experienced at the site; Low seabed temperature; Uncertainty relating to the compartmentalisation of the reservoir; Issues of flow assurance including, multiphase tie back to SVT, hydrate prevention and formation water

prevention.

1.1.1 Project Alternatives To overcome these challenges the Laggan project has undergone a detailed concept selection process to identify the optimum development concept for the field. TOTAL initially considered a wide variety of potential development options for Laggan-Tormore looking at both offshore and onshore processing of the produced gas. The main difference between the offshore processing options was the type of facilities used to accommodate the offshore processing facilities. These ranged from floating platforms e.g. semi-submersible platforms and FPSOs to structures such as a Tension Legged Platform. The final option involved no offshore platform structure, with production through subsea facilities with onshore processing at SVT. An environmental screening study was undertaken of all the development concepts identified during 2005-2007, and the outcomes of this study informed the TOTAL decision making process. After evaluation of the conceptual studies for the project, TOTAL concluded that the optimum development concept for Laggan-Tormore is a subsea tie-back to SVT, including new onshore gas processing facilities at SVT.

1.1.2 Project schedule Fabrication, installation and commissioning of the new offshore and onshore facilities will begin in early 2010 and continue through to early 2012. Drilling of the development wells offshore is expected to commence in the second quarter of 2011 and continue through to the middle of 2013. First gas is expected to be produced in mid 2013 (see Figure 1-1).

1.1.3 Policy, legal and administrative framework The Laggan-Tormore project will be subject to the requirements of UK and EU Legislation, in addition to other international treaties and agreements. The key piece of environmental legislation for the project is the Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects) Regulations 1999. These regulations require the undertaking of an Environmental Impact Assessment (EIA) and the production of an Environmental Statement (ES) for certain types of offshore oil and gas developments likely to have a significant effect on the environment. The approval of this ES is required before approval of the Field Development Plan under the Petroleum Act 1998. An EIA is mandatory for any development that is expected to produce more than 500 tonnes (ca. 3.1 mbd) of oil per day and more than 500,000 m3 (ca. 17.4 mmscf) gas per day. An EIA is also required for pipelines greater than 40 km and with an overall diameter of more than 800 mm (ca. 31.5"). An EIA is also required to support the Works Licence application for works within the 12 mile limit which occur below the high water mark (MHWS) under the Zetland County Council Act 1974. The offshore EIA/ESs will support this Works Licence application. Furthermore, TOTAL internal environmental policy also requires that an EIA be undertaken for all new projects. By undertaking an EIA, TOTAL will ensure that all potential impacts from the project will be considered and a full consultation exercise with all stakeholders will be undertaken. As well as the requirement to carry out an EIA, there are also a number of other key regulatory drivers applicable to the Laggan-Tormore development in offshore waters. These include (amongst others): Petroleum Act 1998; Coast Protection Act 1949; Petroleum Licensing (Production) (Seaward Areas) Regulations 2008 Food and Environment Protection Act 1985; Offshore Petroleum Activities (Oil Pollution Prevention and Control) Regulations 2005; Offshore Chemical Regulations 2002; Offshore Petroleum Activities (Conservation of Habitats) Regulations 2001 (as amended) Offshore Marine Conservation (Natural Habitats &c.) Regulations 2007 Merchant Shipping (Prevention of Pollution by Garbage) Regulations 1998.

1.1.4 EIA Strategy and Scope Due to the geographic spread and different regulatory regimes for the offshore and onshore elements of the Laggan-Tormore development, there will be three EIAs undertaken: The West of Shetland offshore EIA will cover the following: Laggan-Tormore wells and subsea facilities; Import pipeline from Laggan-Tormore to MHWS1 at Orka Voe.

1 MHWS Mean High Water Springs.

Formatted: Not Highlight





The East of Shetland offshore EIA will cover the following: Export pipeline MHWS at Firths Voe to FUKA gas pipeline tie-in at MCP-01. The onshore EIA will cover the following: Gas import pipeline from MLWS2 in Orka Voe to SVT; New infrastructure development at SVT; and New gas export pipeline from SVT to MLWS in Firths Voe. This document acts as the summary scoping report for both the West of Shetland and East of Shetland EIAs. Due to the different regulatory regime, the onshore aspects of the project will be addressed in a separate scoping report, however, to ensure both internal and external stakeholders get a view of the entire project, an overarching EIA Bridging Document in the form of a non-technical summary, will also be provided for public circulation following submission of the final Environmental Statement. A separate scoping document for the onshore EIA will be published in due course. TOTAL will provide a website for dissemination of project information, including the Environmental Statements and associated Non-Technical Summaries.

1.1.5 Purpose of the summary scoping report This scoping document has been produced to provide the regulators, their advisors and other interested stakeholders with an overview of the Laggan-Tormore project by presenting the available information on the project in a concise format. The document also aims to provide an initial appraisal of the potential effects of the project on the environment and recommendations for the scope of the Environmental Impact Assessment (EIA). The main objectives of this scoping exercise are to: Provide an overview description of the proposed Laggan-Tormore Development (offshore aspects) (see Table

2-1); Review existing sources of information and present an overview of the existing understanding of the

environment in the area (see Tables 2-2 - 2-5); Identify what are viewed to be the potentially key areas of impact associated with the project, potential

mitigation measures and studies proposed for the EIA to address these issues further (see Table 2-6); Outline the proposed consultation and feedback strategy to be followed during the EIA process (see below). Provision of this information at an early stage will allow stakeholders to form a considered view on the scope of the offshore EIAs being proposed for the Laggan-Tormore development and to enable them to provide an opinion on the following: Identification of potentially significant environmental effects and hence exclusion of non significant effects from

further consideration; Comment and input on environmental data sources of relevance to the EIA; Agreement on any additional environmental survey and modelling studies required to support the EIA; Alternatives and mitigation measures to be considered; Methods and criteria to be used for prediction and evaluation of effects; Additional stakeholders to be included in the consultation process; and The structure and content of the final Environmental Statement (ES). Feedback from stakeholders will be collated and this scoping report finalised to address feedback received. The final scoping report will be the agreed terms of reference for the subsequent EIAs.

2 MLWS Mean Low Water Springs. 3 There will be some overlap between the offshore ESs and the onshore ES (between MHWS and MLWS). This is to enable full scope of coverage in the offshore ESs to support the Works Licence application under the Zetland County Council Act 1974.




2 PROPOSED DEVELOPMENT PROJECT The Laggan field will be developed as a subsea development with a well design life of 20 years and a facilities design life of 30 years. The subsea wells will be tied back via two multiphase pipelines to the Sullom Voe Oil Terminal (SVT) in Shetland, where new gas processing facilities will be built. The dehydrated gas will be exported to the St Fergus gas terminal via a new build gas pipeline that will tie-in subsea to the existing TOTAL FUKA gas pipeline close to the decommissioned MCP-01 platform (see Figure 2). The condensate separated from the gas during processing at SVT will be stabilised and exported by tanker.

Drilling history Laggan condensate discovered by appraisal well in 1986 Two further Laggan appraisal wells in 1996 and 2004. Tormore reservoir discovered by exploration well in 2007.

Potential number of wells 5 x production wells at Laggan (including possible re-entry and side-track of existing suspended well 206-1a-4z)

3 x production wells at Tormore (including possible re-entry and side-track of existing suspended well 205-5a1)

Although the final well design is not yet known, wells are expected to be highly deviated and use a combination of water based and organic phase drilling fluids. Drilling waste disposal options will be dependant on the types of drilling fluids finally chosen.

Drilling Rig 4th Generation semi-submersible mobile drilling unit Well Completion No down hole chemical injection requirements as risk of scale is considered

low; Hydrate inhibition will be through methanol injection as the wellhead; Sand production is expected after ca. 6 years and sand control will be included

in the well completion design; Well interventions are expected to be of low frequency with ca 1-2 well

interventions per well during life of field (20 years). Subsea installation Subsea installation to be undertaken by Multipurpose Support Vessels (MPSV)

using ROV Subsea facilities 6 slot template manifold at Laggan with 5 x wellheads/xmas trees. 6 slot template manifold at Tormore with 3 x wellheads/xmas trees.

Allowance for future wells within template design. Subsea multiphase flowmeters. Fishing protection of subsea structures being addressed as part of engineering

design. Possible future subsea compression at Laggan or Tormore.

Subsea control 1 x 8" electrohydraulic control umbilical; or 2 x 6" electrohydraulic control umbilicals West of Shetland Flowlines/Pipelines

2 x 18" surface laid multiphase pipelines Laggan-Tormore to SVT forming complete pigging loop from SVT;

East of Shetland Pipeline 1 x 30" concrete coated export pipeline to tie in to FUKA pipeline system via a subsea tie-in at MCP01

Flowlines/Pipelines Protection

18" and 30" pipeline will only be rock dumped where required for seabed preparation or stability;

Methanol line and umbilical(s) will either be trenched/buried or rock dumped for protection. Trenching/burial will be the preference to reduce the amount of rock dumping required.

Hot-tap tees will be rock dumped. Gas production Gas condensate will be produced at a maximum daily rate of 500 MMscfd with an

average annual production rate of circa 450 MMscfd.

Table 2-3 Shetland Coastal Waters (including Yell Sound) Environmental Information Physical Coastal geomorphology comprises Salt marshes, mud flats and houbs3 (small areas in Sullom Voe)

Exposed coastline cliffs (much of northern Yell Sound) Low lying shore, rock cobble and shingle (much of Sullom Voe) Sand beaches (small areas of Sullom Voe) Man made structures, jetties, piers, slipways and gabions. Habitats Present in Yell Sound can be summarised as: Littoral habitat in the north sediment beaches including infauna such as polychaete

worms, exposed areas dominated by yellow and grey lichens and barnacles. Fucoids, mussels and limpets in more sheltered areas.

Sublittoral habitat dominated by kelp forests with the diversity of flora increasing with shelter.

Fish Anglerfish or monkfish, Atlantic salmon, ballan wrasse, brown/sea trout, butterfish, cods, common dragonet, European eel, fifteen spined stickleback, flounder, painted goby, plaice, right-eyed flounders, sand goby, scorpion fish, sea scorpion, spotted snake blenny, three spined stickleback and two-spotted goby recorded in the coastal waters around Shetland.

Seabirds Internationally important conservation area for breeding seabirds including fulmars, gannets, shags, gulls, terns and auks which inhabit the area between April and August inclusive.

There are a number of designated conservation areas along the Shetland coast and within Yell Sound due to important breeding seabird colonies amongst others (see Conservation below).

Marine Mammals Harbour porpoise, killer and minke whales sighted regularly while occasional sightings of white beaked dolphin, Atlantic white sided and Rissos dolphins, long finned pilot, fin and sperm whales. Minke and killer whales, are regularly sighted in Yell Sound although rarely encountered in Sullom Voe. Harbour porpoises are recorded regularly on the east coast of Shetland in Orka Voe and Firths Voe.

Harbour and grey seals occur regularly around the coast of Shetland with approximately 4,900 adult harbour seals and 3,100 grey seals known to haul out in Shetland during pupping seasons. Yell Sound is the most noteworthy harbour seal haul out site in Shetland supporting approximately 1,000 adults (>1% of the UK population).

Fisheries Creel fishing, scallop dredging, Scottish seine and gill netting are all known to take place in the area of St. Magnus Bay. Demersal trawling is also reported in these waters. Within Yell Sound creel fishing is undertaken along the shore and scallop dredging in deeper waters. Dog whelks are also fished in the area around Orka Voe.

Tourist boats also travel the coastline of Shetland for the purposes of bird and wildlife watching and fishing although details of the most intensive areas of use are not known at this time.

Conservation A number of nationally and internationally important designated areas exist mainly for coastal bird breeding populations and landscape and vegetation features unique to the UKs most northern islands. A summary of the coastal designations relevant to the Laggan-Tormore development is given in Appendix 2.

Socio-economic Tourism contributes 16.5 million to the Shetland economy each year and an estimated 60,000 visitors, both business and tourist, visited Shetland in 2006. Recreational use of the coastal area is mainly for yachting, coastal fishing, wildlife watching and diving.

Aquaculture is a major industry in Shetland and there are a number of fish and shellfish farms off the coast of Shetland.

Other sea users in the area include inter-island ferries, marinas and potential renewable energy developments.

The site is rich in rare northern species, such as arctic sandwort Arenaria norvegica ssp. norvegica and northern rock-cress Arabis petraea, and includes the endemic Shetland mouse-ear Cerastium nigrescens, found only on serpentine rocks at this site.
