Norway's Island Offshore has stretched a charter for a platform supply vessel (PSV) with Repsol.

The 4,100-dwt Island Challenger (built 2007) will work for the oil company for another year, plus options, it said.

The new term starts on 22 November, but no rate was given.

Island Challenger entered into a five-year contract with Talisman in November 2013. Repsol now operates the same installations.
