Seajacks currently owns and operates two self-propelled jack up vessels out of Great Yarmouth in the UK: the Seajacks Kraken and Seajacks Leviathan. Both vessels are built for installing offshore wind turbines, and being able to perform other operations for the North Sea oil and gas industry.

Seajacks Kraken is currently on contract to TAQA carrying out gas field service work and will shortly commence a 15 month contract for Dong Energy to install turbines at the Walney offshore wind farm, located in the Irish Sea. Seajacks Leviathan is currently on a 15 month contract with Fluor to provide installation services at Greater Gabbard.

Riverstone said that it plans to grow Seajacks into a major European offshore wind service business, with an operational base in the UK. The initial focus will be on expanding the current fleet of vessels to serve the market for turbine installation and maintenance.

Blair Ainslie, managing director of Seajacks, said: “We believe that with Riverstone’s knowledge, expertise and substantial financial resources, Seajacks will to be able to grow our business footprint, creating new jobs and helping the UK and other European governments meet their ambitious offshore wind targets.

“We particularly look forward to playing a significant role in the development of the UK Round 3 sites, which are expected to represent in excess of GBP100bn pounds of investment.”
