Boskalis’ semi-submersible heavy transport vessel Mighty Servant 1 has arrived in Haugesund, Norway, to deliver the 23,000-tonne DolWin Epsilon platform.
HLPFI reported towards the end of last year that the high-voltage direct current (HVDC) converter platform, which will transmit wind-generated electricity from several offshore wind farms to the onshore grid, was loaded onboard the vessel at Seatrium’s shipyard in Singapore on October 12.
Measuring 73 m wide, the platform is almost one-and-a-half times as wide as the deck of the Mighty Servant 1. To accommodate the load, the deck was extended with four outriggers – two on each side of the vessel – to make the vessel wider at crucial points to carry TenneT’s 82 m-long and 84 m-high platform.
Now in Norway, Aibel will still carry out final technical works. Hitachi Energy as Aibel’s subcontractor and supplier for the HVDC technology, will install the converter and transformers. This summer, the platform will be transported self-floating and installed at its final destination in the German part of the North Sea.
