DeepOcean wins cable installation contract for Walney Extension offshore wind project

Published 16 October 2015

Subsea services company DeepOcean has secured a cable installation contract from Dong Energy for the 660MW Walney Extension offshore wind project in the Irish Sea.


Work under the contract includes the installation and trenching of a total of 136km long offshore export cables and a 23km interlink cable for the project.

The cables will be pulled ashore near Heysham and will link the two offshore sub station platforms at the windfarm, DeepOcean said.

DeepOcean will carry out the offshore work using its new cable installation vessel Maersk Connector in 2017.

This is the second contract for DeepOcean's Maersk Connector, which will join the company's fleet in the first quarter 2016.

The contract will also require DeepOcean to provide route engineering.

DeepOcean Greater North Sea executive vice president Ottar Maeland said: "We are delighted to be expanding our relationship with DONG Energy from the offshore oil and gas market to the key growth area of offshore wind.

"This is a major contract using our state of the art new cable installation vessel Maersk Connector and the versatile installation and trenching vessel Havila Phoenix.

"DeepOcean's investments in these advanced vessels and trenching systems are helping our customers bring down the risk and cost of offshore wind developments. DeepOcean's investments and capabilities illustrate how the UK supply chain is working hard to support our Customers in bring clean power to millions of UK families."

The Walney Extension Project including WOW03 (west) and WOW04 (east) will have up to 90 turbines each with a 7MW or 8MW output.
