Gravity based structures are support structures held in place by gravity. They are widely used in civil engineering and the oil and gas industry. Now, with the trend of bigger wind turbines installed at higher water depth, several gravity based wind turbine foundations have been developed. However, the movements of gravity based structures during transportation and installation are not well captured by standard design methods. It is necessary to optimize the workability of the installation of such large concrete structures, to improve scalability and reduce the total cost of offshore wind energy. It is also necessary to enable transport and installation at more severe environmental conditions.
Objective and organisation
The objective of the GBS wind JIP is to improve the engineering methods for the logistics, transport, and installation of gravity based wind turbine foundations. This will lead to more effective and safer operations with better workability and optimised logistics.
The GBS JIP will be conducted as a 2-year Joint Industry Project in close co-operation with energy companies, operators, yards and marine system suppliers. MARIN will act as JIP manager and sign participation agreements with all members. All participating companies will be represented in the JIP Steering Group with meetings during the BlueWeek every 6 months. Presentations, reports and other relevant information will be posted on the confidential project website.
