Wind Energy – Floating Wind
The Salamander floating offshore wind project, a joint venture between Simply Blue Group, Ørsted and Subsea7, has awarded the pre-FEED foundation design to Ocergy for its OCG-Wind foundation technology.
Last year, Salamander signed a memorandum of understanding (MoU) with Ocergy to evaluate its foundation design for the development in north east Scotland. The project will be a contributor to ensuring the UK government’s target of delivering 5GW of operational floating offshore wind by 2030.
Ocergy has developed OCG-Wind, a novel and efficient floating wind turbine foundation, to support very large wind turbines (>10MW), designed for development of large-scale wind farms. It is targeting a levelised cost of energy (LCOE) that can start to drive reductions in floating offshore wind farms to eventually be competitive with fixed offshore wind farms.
OCG-Wind is a semi-submersible platform designed to utilise the industrial performance of the hull fabrication and assembly through the maximisation of the local supply chain. The hull is made of three outside circular columns connected mechanically with trusses to a central column that supports the wind turbine.
A feasibility study considered all aspects of the design, technical performance, fabrication, assembly, operations and installation of the OCG-Wind for Salamander. It also reviewed the compatibility of the OCG-Wind platform to the site, inclusive of performance, and supply chain and local content management, as well as identified schedule risks and overall project costs. This feasibility study will now progress to pre-FEED phase.
Salamander, located 35km off Peterhead, is designed to provide the Scottish supply chain with an early capacity development opportunity, enabling it to play a much greater role in subsequent large-scale floating offshore wind buildout. The project will deploy innovative and cutting-edge floating offshore wind technologies to support the cost reduction and learning journey needed for the commercial deployment of floating offshore wind.
Salamander is intended to be progressed through the innovation track of Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round. The INTOG round will grant seabed leases through an auction process, which will be split into two pots – one for smaller scale innovation projects of less than 100 MW and one for larger projects linked to oil and gas infrastructure.
