2011, JPKenny, Zone 1 - Moray Firth, Export Cable Route Concept Engineering series https://portal.medin.org.uk/portal/start.php?tpc=015_af2cd5cb-604e-430d-b4ce-1cc64adf5831 In January 2010, EDP Renováveis (EDPR) and SeaEnergy Renewables Limited (SERL) were awarded a Zone Development Agreement by The Crown Estate to develop wind farm sites within the Moray Firth zone, one of the nine zones comprised in Round 3 of the UK offshore wind competitive leases. EDPR and SERL have formed Moray Offshore Renewables Limited (MORL) to develop 1.5GW of offshore wind by 2020 within the zone. The objective of this desk-top study is to develop, evaluate, compare, and rank cable route options from the offshore substation to the onshore connection point at Peterhead, taking into consideration all aspects of routing issues including seabed and ground conditions, engineering constraints, third party interactions, environmental and physical constraints, and restricted zones. Additional ranking criteria for the routes comprise socio-economic considerations, risk, and through-life cost. Up to four routes will be recommended and ranked, each comprising offshore and onshore corridors, and proposed locations for the landfall and the onshore substations. Work related to Stage 1 of Work Package 7 – Cable Routing Concept Engineering followed the following objectives: • Generation of a comprehensive GIS geo-database and associated constraint maps; • Study of the bathymetry and slopes; • Appraisal of the proposed landfalls; • Development of cable routes options through a comprehensive desk-top route selection process. The objectives of Stage 2 of this desk-top study were to develop indicative cost estimates and to compare the route options in terms of complexity, risks and costs. This report was not updated at the end of Stage 2. Stage 3 had the aim to finalise the preferred concept routes by taking into account any new information arising from the advancement of parallel project activities. This report also discusses cable installation methodologies, construction vessel types, and decommissioning requirements, which are part of Work Package 9. 20260910T08:54:45
