Jan de Nul Group has laid sea cables for TenneT’s Hollandse Kust North and West Alpha grid connections at the bottom of Heemskerk beach and in the seabed.
This concludes the job for the intertidal trenching vehicle Moonfish off the coast of North Holland.
The first of the two front cables (West Alpha) will be sailed from South Korea to the Netherlands before the end of the year. Upon arrival, cable laying will start immediately.
Earlier this week, the last two of four sea cables (220kV) were also buried by contractor Jan de Nul. These cables are intended for the connection of the Hollandse Kust wind farm (West Alpha). These cables are now almost 6km each ‘capped’ in the seabed.
Once the rest of the cables are brought to the Netherlands, the sections will be connected with a socket connection at sea.
Jan de Nul Group will then lay the rest of the cables up to the socket at sea. For West Alpha, that socket will be located about 50km off the coast of Egmond aan Zee. Because the cables cannot be laid as the crow flies, these cables will each be 70km long in total.
For Hollandse Kust (North), the transformer platform is now 18.5km off the coast of Egmond aan Zee. The sea cables for North are already ready in the seabed.
