Belgian contractor DEME has been awarded engineering and installation contracts from cabling specialist Prysmian for two gigascale Dutch offshore wind projects.

The order is the most extensive cabling award in DEME’s history and its first project with Prysmian’s 525kV high voltage direct current (HVDC) cable technology. It is worth more than €300m ($321m).

The contracts for the Ijmuiden Ver Alpha and Nederwiek 1 far offshore projects – which combined have a capacity of 4GW – include cable installation, landfall and rock placement, dredging and infrastructure works.

“Our modern and versatile fleet is also ideally suited for such a complex project,” said Philip Scheers, business unit director at DEME Offshore.

“We can provide cable installation vessels, hopper dredgers, and fall pipe vessels, all of which are operated by our own highly skilled and experienced crews.”

DEME will deploy several vessels, including cable installation vessels, hopper dredgers and a fall pipe vessel. Works are slated to start in stages from next year on.

The grid links for Ijmuiden Ver Alpha and Nederwiek 1 are operated by transmission system operator TenneT and will link the future wind farms from the southern Dutch province of Zeeland. The first connection is scheduled to be operational in 2029, and the second a year later.

The Netherlands in late February had opened a tender for the Ijmuiden Ver Alpha and Beta sites, which each have a capacity for 2GW of offshore wind. The tender closed on 28 March 2024, and the government is slated to announce the result towards the summer.
The Ijmuiden Ver auction has been criticised for containing a very high element of negative bidding, which could cost developers – and eventually power consumers – dearly.

The country plans to tender off the Nederwiek 1 site next year.
