After Norwind Offshore announced it had closed the acquisition of six CSOVs from Edda Wind, UK offshore vessel owner North Star revealed it had completed the acquisition of four service operation vessels (SOVs) from the same company.

The transaction takes North Star’s offshore wind fleet to 14 vessels, establishing it as the world’s largest offshore infrastructure service provider by fleet size and charter backlog.

The acquisition comprises four high-specification vessels – the Goelo Enabler, Boreas Enabler, Nordri Enabler, and Sudri Enabler, together with all associated charter parties. A total of 160 offshore roles will continue to support these vessels, alongside North Star’s existing operational teams. All four SOVs are currently deployed on offshore wind contracts.

The company stated that the acquisition complements its ongoing investment in newbuild vessels.

North Star is expected to generate around £100m of run-rate EBITDA, up more than threefold in the last four years. Most of this increase is derived from the growing SOV fleet business.

“Bringing these SOVs into our fleet broadens our customer offering, strengthens our platform and reinforces our presence in key European markets. It also underlines our leadership in the region’s SOV sector and provides a strong foundation for the next phase of expansion across the business,” said Gitte Gard Talmo, North Star CEO.

Edda Wind entered into agreements in early March to sell its entire fleet of SOVs and CSOVs, including units under construction, to North Star and Norwind. After the two transactions, Edda Wind will own only one SOV, which will also switch hands when certain conditions are satisfied later in the year. This is anticipated to occur in the fourth quarter of 2026.
