Norway's GC Rieber Shipping has sealed a new time-charter deal with a "Tier 1 client" for an offshore construction vessel (OCV).

The 6,300-dwt Polar Queen (built 2011) will work for the unnamed charterer for two periods in 2019.

The first is for 45 days plus options and starts soon.

The next job will take 50 days from next February.

The vessel will be used to perform walk-to-work duties and accommodation services.
