The project scope includes route engineering as well as the installation and trenching of a total of 136 km offshore export cables and a 23 km interlink cable. The offshore work will be carried out in 2017 by new cable installation vessel Maersk Connector which joins the DeepOcean fleet early 2016.
The Walney Extension Project, WOW03 (west) and WOW04 (east), is anticipated to have a total capacity of 660MW. With up to 90 turbines each with a 7MW or 8MW output and 2 offshore substations and is to be constructed by DONG Energy AS, as the sole owner of the Project. WOW03 and WOW04 will consist of 2 x 220kV independent electrical systems each with their own offshore sub-stations.
Ottar Maeland, EVP Greater North Sea for DeepOcean, 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.”
The Walney Extension Project is located in the Irish Sea west-south-west of the Isle of Walney coast in Cumbria.
Earlier this week the subsea specialist was awarded a contract for the provision of post-lay trenching and survey works in Australia.
