Dudgeon Offshore Wind Limited (owned by Statoil ASA and Statkraft) has awarded Seaway Heavy Lifting the contract for the transportation and installation of 67 foundations and 1 substation as part of the Dudgeon Offshore Wind Farm project, 32km off the coast of Norfolk, UK.
The contract will cover storage, transportation, and installation of monopiles, transition pieces, jackets, and the offshore substation jacket and topside.
The monopiles will vary from 60-78m-long and 600–1000-tonne in weight.
The substation topside weight is estimated to 2000-tonne. Installation work, in 18-25m deep water, will start between March and May 2016, and will be completed in August 2016.
The Dudgeon Offshore Wind Farm lies to the north of the Sheringham Shoal Wind Farm where Seaway Heavy Lifting successfully completed the installation of Wind Turbine Generator (WTG) foundations and substation topsides in 2011 on behalf of Statoil and Statkraft.&
The Seaway Heavy Lifting vessel Oleg Strashnov (pictured)will be used for the inshore loading, transportation, and installation of the monopile foundations from a storage site to the offshore Dudgeon installation site.
The Oleg Strashnov is a self-propelled DP crane vessel with a main hook capacity of 5000-tonne, and a hook height of 100m above sea level. It has a maximum deck load of 8500-tonne and is able to carry four monopiles, four transition pieces, and all the equipment required for the successful installation.
