Offshore Wind Force, a joint venture between Netherlands-based contractors Volker Stevin Offshore and Boskalis Offshore, has awarded U.K.-based FoundOcean a grouting contract for the West of Duddon Sands Offshore Wind Farm.
The project is being constructed by DONG Energy and ScottishPower Renewables in the east Irish Sea, approximately 14 km from Walney Island. It is located near an array of projects, including Walney I and II and the Ormonde Offshore Wind Farm, whose 31 jacket foundations were grouted by FoundOcean in 2010.
The 108 3.6 MW turbines will be housed on monopiles, which have been designed with rapid grouting in mind, FoundOcean explains. Fixed grout lines will be fabricated on the transition piece with flexible hoses extending to the turbine deck. FoundOcean will connect their grout hoses to the flexible hose at the deck level, and once grouting is complete, both sets of grout hoses will be detached.
FoundOcean will grout the foundations between May and November of this year using BASF's Exagrout Masterflow 9500.
