Over the past few months we have been busy preparing our Haven SeaSeven for an exciting project commencing this month for Jan De Nul Group.
TenneT is constructing two offshore platforms, one for Hollandse Kust (noord) and one for Hollandse Kust (west Alpha). These platforms gather the wind energy generated by the corresponding wind farms and transform this energy from a voltage of 66kV to 220kV.
To transport the energy to the mainland, two submarine power cable systems per platform run from the offshore platform to the onshore grid, meaning in total four cable systems.
They arrive on land just north of Wijk aan Zee, in the municipality of Heemskerk. More information can be found on: https://lnkd.in/d_Kvqxs
The Consortium Jan De Nul Group and LS Cable (JLC) has been awarded the supply and installation of the high voltage cables for the grid connection.
Jan De Nul Group will be chartering #Red7Marine’s 400t Haven SeaSeven jack-up barge to act as a tensioner station to reduce the total export cable tension during the cable installation.
As a part of the project, Red7Marine’s in-house team have fabricated cantilever arms and a platform which has been welded on to the side of the barge for the cable to sit on.
The barge recently arrived in Ijmuiden Port ahead of the works on-site commencing.
