Heerma Marine Contractors heavy-lift behemoth Sleipnir has installed the 49-meter-high, 2,100-tonne jacket for the Hollandse Kust (west Beta) transformer platform over the past weekend.Â
Heavy transport vessel Mighty Servant 1 has completed its journey from the Seatrium shipyard in Singapore to the Aibel shipyard in Haugesund, Norway, with the 900 MW DolWin Epsilon platform aboard. The 23,000-ton HVDC converter platform will transmit the wind-generated electricity from several German offshore wind farms to the onshore power grid.
Jan De Nul, along with its consortium partners LS Cable & System and Denys, has signed contracts for two 525 HVDC cable systems. These systems will connect offshore wind farms to the onshore grid via the BalWin4 and LanWin1 grid connections.
Heavy transport vessel Mighty Servant 1 has set course for the Aibel shipyard in Haugesund, Norway, transporting the 900 MW offshore wind platform DolWin epsilon. The vessel “piggybacked” the platform at the Seatrium shipyard in Singapore following three years of construction.Â

A few weeks after the successful load out at Heerema Fabrication Group yard, the steel substructure for the transformer platform Hollandse Kust (West Alpha) will leave the port of Vlissingen over the coming weekend (August 14 or 15).
TenneT will be able to provide more power via the direct current connection DolWin6, now that the 900 MW offshore platform DolWin kappa sailed out from the Dragados Offshore shipyard in Cádiz, Spain. With this, Europe’s major offshore transmission system operator, has reached a new milestone in its quest to bringing more green wind power…
The Dutch subsea cable specialist WIND has secured a contract to provide cable transfers and cable storage for offshore spare export cables for TenneT.Â
Boskalis heavy transport vessel Mighty Servant 3 has completed the transport of Tennet’s Beta substation of the Hollandse Kust Zuid wind farm. Boskalis noted that the involvement in such projects is its way of taking an active role in enabling the energy transition in the Netherlands.Â
The 700 MW Hollandse Kust Zuid (HKZ) Beta topside weighing 3,950-tonnes has been loaded out at the Drydocks World Dubai and is on its way to the Netherlands. Petrofac informed that it has completed the construction of the second High Voltage Alternating Current (HVAC) offshore transformer station topside for the Dutch-German transmission grid operator Tennet.Â
The 700 MW Alpha topside for the Hollandse Kust Zuid (HKZ) project has been completed by Drydocks World (DDW). The unit has already sailed away from the fabrication yard in Dubai to the Netherlands onboard the semisubmersible heavy lift vessel Tai An Kou. The vessel, according to the shipping data, is now sailing in the Red…
The jacket foundation for TenneT’s Hollandse Kust (noord) substation has been installed in a joint operation by DEME Offshore and Scaldis SMC. The 2,100-tonne jacked installation has been completed by the heavy lift vessel Gulliver.Â
Heerema Marine Contractors’ LNG-fueled semi-submersible crane vessel Sleipnir has completed the installation of the second jacket of TenneT’s offshore transformer platforms for the Hollandse Kust Zuid (HKZ) wind farm in the North Sea.
Denmark has approved a plan to build the first energy hub in the North Sea. This is a small artificial island where the connections of wind farms converge. The energy can then be transported to the mainland via a single cable.
Heerema Fabrication Group will construct the Hollandse Kust (noord) offshore transformer substation jacket. The contract for this was signed with Iemants (part of Smulders). The jacket will be 44 metres high and consists of 1600 tonnes of steel.
The first jacket of TenneT’s Hollandse Kust (Zuid) offshore platform has been installed in the seabed. The heavyweight Alpha jacket of 3200 tonnes was transported and installed by Heerema’s heavy lift crane vessel Sleipnir.
PRESS RELEASE – Blue Offshore has moved 8,000 tonnes of high voltage cable to Rotterdam. The cables will form the connection of Tennet’s Hollandse Kust Zuid Alpha Platform to the onshore grid.
