Big-name shipping owners are vying to win an Equinor tender to build and operate offshore wind support vessels.

Market sources told TradeWinds that as many as 18 companies could offer-in for the work involving three or four new service operation vessels (SOVs) for long-term charter to the Norwegian energy giant to support its huge offshore wind build-out programme.

Bidding is due to open this month for what is a crucial and unique deal in a depressed market for traditional offshore shipowners.
