FoundOcean has been awarded a grouting contract by Offshore Wind Force, the joint venture of contractors Volker Stevin Offshore and Boskalis Offshore. It relates to the 389MW West of Duddon Sands project, under development by DONG Energy and ScottishPower Renewables.
FoundOcean will grout the 108 monopiles at the project site, 14km offshore of Walney Island in the Irish Sea. The project is located close to DONG's Walney 1 and 2 assets, as well as Vattenfall's 150MW Ormonde offshore wind farm, whose 31 jacket foundations were grouted by FoundOcean in 2010.
The West of Duddon Sands' monopiles have been designed with rapid grouting in mind. Fixed grout lines will be fabricated on the transition piece, with flexible hoses extending to the turbine deck. FoundOcean will connect grout hoses to the flexible hose at the deck level and on the completion of grouting, both sets of hoses will be detached. The work will be undertaken between May and November 2013.
