Contractor Akofs Offshore will provide well intervention services for Equinor as part of a five-year deal worth about £275 million.
The firm will supply its Akofs Seafarer vessel for the contract, which includes a three-year extension option.
Equinor said it operates about 560 subsea wells on the Norwegian continental shelf, all of which require maintenance, repairs and new production actions.
Geir Tungesvik, Equinor’s senior vice president for drilling and well, said: “The past three years we have been performing light well intervention activities during the periods of the year with best weather. We now wish to perform all-year interventions, with a vessel working in the same way as mobile rigs when it comes to waiting on weather. This is a robust vessel which will be able to operate large parts of the year.”
Earlier today, Akastor said it had agreed to sell 50% of Akofs to Mitsui.
