ABERDEEN, UK — TwinHub has secured a 15-year revenue support from the UK government for the first floating offshore wind project in the Celtic Sea.
The offshore site investigation works have commenced, and Phase 1 of the survey works has been awarded to Aratellus Offshore Ltd., which is subcontracting Sulmara Subsea Ltd., to perform the geophysical survey.
The TwinHub Floating Offshore Wind Farm site is located 16 km off the coast of Hayle in Cornwall, UK.
The investigation works represent a significant milestone for the project, which is set to be the first floating offshore wind farm to be built in the Celtic Sea, having been successfully awarded a contract for difference in July’s auction round. The survey vessel Vos Sweet mobilized from the port of Falmouth on Aug. 17, with field operations anticipated to last between two to three weeks.
The survey has been commissioned through the European Marine Energy Centre Ltd. (EMEC) as part of the AFLOWT Project and part funded by the European Regional Development Fund.
The geophysical survey's goal is to make it possible to plan subsea routes, inspect existing cables, and perform FEED and detailed design of mooring anchors and chains. A side scan sonar, sub-bottom profiler, ROV and a magnetometer are among the tools that will be used.
The results of the final project will be used to progress the FEED for the TwinHub project, which is developed by Hexicon and supported by Bechtel. The project will see the deployment of Hexicon’s TwinWind technology, which is expected to be the first duel turbine floating foundation deployed at large scale globally.
