Norway's SolstadFarstad (SOFF) has agreed a contract extension for a construction ship in the US Gulf.
Blue Marine has stretched the deal for the 9,000-dwt Far Sentinel (built 2015) by 18 months to June 2020.
The shipowner said the contract has incorporated an early cancellation clause, which includes a "significant" termination fee.
But it added that this cannot be exercised before November 2018.
