Publication Date

DEME Offshore has been awarded the export cable contract for Vattenfall’s Norfolk Boreas Wind Farm in a consortium with LS Cable & System. The consortium is also selected as the preferred bidder for the remaining projects in Vattenfall’s Norfolk Zone.

The contract includes the design, engineering, procurement, manufacturing and testing of around 360 km of High Voltage Direct Current (HVDC) export cables and fibre optic cables, including the offshore installation and onshore jointing. For DEME, the share in the project represents a sizable contract (1).

Philip Scheers, Business Unit Director at DEME Offshore, comments: “We are delighted that Vattenfall has selected DEME and LS Cable & System for this major wind farm. Our dedicated vessels, renowned for their performance in the industry, and expert team enable us to provide a very efficient solution for such a large-scale cabling scope. We are proud to partner with Vattenfall, which shares our views for a sustainable world, and to play a role in delivering green energy to millions of UK homes. We look forward to working with our consortium partner LS Cable & System to successfully and safely deliver this project.”

Works will be executed in 2026, involving a cable installation vessel, a trailing suction hopper dredger and a fallpipe vessel from the DEME fleet.

Located 47 kilometres off the Norfolk coast in the UK, Norfolk Boreas is the first phase of Vattenfall’s Norfolk Offshore Wind Zone and represents an installed capacity of 1.4 GW. Once completed, the entire zone can produce clean energy for more than four million households and save about six million tonnes of carbon dioxide.

Catrin Jung, Head of Offshore Wind at Vattenfall, said: “We look forward to working closely with LS Cable & System and DEME Group to make this project a success. The Norfolk Boreas Wind Farm is an important project for Vattenfall and major step forward for delivering fossil-free living within a generation in the UK.”

HyungWon Kim, Vice President at LS Cable & System, said: “We are glad to get awarded the Norfolk Boreas project. We are even happier to contribute as a valuable partner of Vattenfall to the way towards a zero-carbon movement.”
