Rates for platform supply vessels (PSVs) have remained weak as recent deals have proved insufficient to thin the tonnage list in the North Sea spot market.

Brokers reported Dof's 4,100-dwt Skandi Sotra (built 2003) fixed at £4,500 ($5,800) per day by Apache for two weeks, while other bookings have been concluded at between £4,800 and £5,250, down from £5,500 at the end of May.
