Seaway Heavy Lifting’s (SHL) vessel Oleg Strashnov has already installed 10 foundations at the Dudgeon offshore wind farm in the UK, according to IHC IQIP, a company that outfitted the vessel with piling and handling equipment for the project.
SHL is in charge of the installation of 67 foundations and one substation at the project site located off the Norfolk coast, with the works expected to be completed by August 2016.
The monopiles are 60-78 metres long and weigh from 600-1,000 tonnes, while the substation weighs 1,800 tonnes.
Oleg Strashnov has been equipped with a 1,400-tonne upending tool, which can tackle monopiles of up to 1,400 tonnes and utilises a fail-safe lifting principle, and an S-3000 Hydrohammer that drives the monopiles into the seabed.
