Solstad Offshore has locked one ship into a long-term contract at the same time as disposing of a platform supply vessel (PSV).

The Norwegian owner said the 4,800-dwt PSV Normand Leader has been chartered by ConocoPhillips for four years, plus three annual options.

ConocoPhillips will take delivery of the ship in April 2018 but the commercial terms of the deal will be kept confidential, Solstad said.
