Norway's GC Rieber Shipping has stretched an OSV charter by five months.
The 6,300-dwt construction vessel Polar Queen (built 2011) will be deployed by an unnamed European client, with the option of another month.
The project is the same that kept the ship busy in the summer of 2018 and 2019.
"The vessel will be used in British sector to perform accommodation services and walk-to-work duties, and commencement will be in April 2020," Rieber said.
"We are pleased with securing backlog in a continuous challenging market. Polar Queen has proven her success in the walk-to-work market, and we are proud to see that the vessel and her capabilities are recognized by our clients", added CEO Einar Ytredal.
In February, the owner extended its charter by a further 50 days.
It was fixed for an initial four months to an unnamed European client in November.
