Jan de Nul installs Hollandse Kust landfall cables

Sunday, October 23 2022

General – Landfall Cables

Both the TenneT sea cables for the Hollandse Kust (north) and the cables for (west Alpha) have been installed by contractor Jan de Nul Group in the bottom of the beach at Heemskerk and in the seabed.

This completes the job for the intertidal trenching vehicle Moonfish off the coast of North Holland. The first of the two cables for (west Alpha) will be sailed from South Korea to the Netherlands before the end of the year. After arrival, the laying of the cables 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 (west Alpha) wind farm. These cables are now each almost 6 km ‘capped’ in the seabed. As soon as the rest of the cables have been brought to the Netherlands, the parts will be coupled at sea with a sleeve connection.

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.
