Oslo-listed Solstad Offshore is focusing more on green recycling as it continues to ditch non-core ships.

Three more unwanted vessels have been sold in recent weeks.

The offshore vessel owner has now sold 13 of 37 ships classified as non-strategic in a divestment tied to its long-term financial restructuring sealed last year.

Solstad said a Singapore subsidiary has offloaded the 5,422-bhp anchor-handling tug supply vessel Nor Tigerfish (built 2007).
