Marine engineering company Van Oord has successfully installed two Offshore High Voltage Stations (OHVS) and the first 77 transition pieces at the Dutch Gemini wind park.
Deploying a heavy lift vessel, the 2,500-tonne platforms were installed in their final location at the wind farm off the coast of the Dutch town Groningen.
The OHVS platforms convert the energy generated to 220V. The platforms are connected to the Dutch power grid via export cables.
Two ships, including Van Oord’s offshore installation vessel Aeolus, will install the remaining 73 foundations for the project later this year.
The wind turbines will be installed in the spring of 2016.
Van Oord’s cable-laying vessel Nexus is installing two export cables, each measuring 100km.
These will be buried in the seabed by its multi-purpose vessel Jan Steen, which is fitted with a larger subsea trencher.
The cable-laying vessel HAM 602 will install the cables between the foundations and the OHVSs and then the Jan Steen will bury them with the trencher.
