UK Energy Minister Andrea Leadsom said: "It’s great to see Dong Energy selecting a British business, Seajacks, to help install the turbines for its Walney Extension offshore wind farm.
"The UK is open for business and this new contract will support growth and local jobs, providing lasting economic security for working people."
Seajacks will deploy its wind farm installation vessel, Seajacks Scylla, which is under construction at the Geoje shipyard in South Korea, in 2017.
The Scylla vessel will install 40 MHI Vestas V164 8.2MW turbines and 47 Siemens SWP-7.0-154 units at the wind farm.
Seajacks UK CEO Blair Ainslie said: "With Scylla, Dong Energy have chartered the largest and most capable vessel in the market which will enable them to transport and install the largest most powerful of new turbines at the deepest and most demanding of high wind locations."
Located next to the 367MW Walney offshore wind farm, the Walney Extension farm is planned to be developed in two phases, each with a capacity of 330MW.
The wind power project is likely to create 230 new jobs during the four-year construction phase and approximately 185 jobs annually during the expected lifespan of 25 years.
Upon completion, the project is estimated to generate enough electricity to power over half a million homes.
