Westermost Rough Offshore Wind Farm
Fabrication of Foundation sea-fastenings
GeoSea, utilising their installation vessel Innovation (the world’s largest jack-up vessel of its kind), were awarded the contract to install the foundation components for Westermost Rough Offshore Wind Farm. Subsequently MCC were awarded the contract for the supply, fabrication and mobilisation of the sea-fastenings for the project.
MCC’s workscope included the supply, fabrication and mobilisation of;
•Monopile Cradle Upending and Support
•Monopile sea-fastening frames
•Transition Piece sea-fastening frames
•Hydraulic Hammer sea-fastening frames
•Drill Rig sea-fastening frames
•HPU sea-fastening frames
•Internal Lifting Tool (ILT) sea-fastening.
The design of sea-fastening relied heavily on the use of hydraulic cylinders for clamping, locking and opening / closing of the cradles. The MCC scope of work was subject to an extremely demanding programme. All activities were completed during an intensive period of less than ten (10) weeks (including an element of quayside assembly and commissioning).
The Westermost Rough Offshore Wind Farm is one of the UK’s Round 2 projects and has been developed by DONG Energy. The wind farm site is situated 8km off the Yorkshire Coast, north of Hull and consists of 35 turbines, each of 6MW capacity, covering a total area of 35km2 and providing enough electricity to power around 200,000 homes.
