Norway's Solstad Offshore has added another two years of contract work in deals with key clients.

The Oslo-listed company said it has signed charter extensions with Norwegian oil major Equinor and Aker BP, in which leading Solstad shareholder Kjell Inge Rokke also holds a stake.

Equinor has declared an option to extend the contract for the 20,700-bhp anchor-handling tug supply (AHTS) vessel Normand Ferking (built 2007) for another year to November 2021.
