Kjell Inge Rokke's AKOFS Offshore has clinched a subsea ship charter extension in Brazil worth $282m.

Oslo-listed parent Akastor said the subsidiary has signed a deal that will keep the 10,900-dwt Aker Wayfarer (built 2010) with oil major Petrobras for another 1,415 days, or almost four years.

The ship has been operating for Petrobras as a subsea equipment support vessel (SESV) on a five-year deal since January 2018.
