Rates have shot up for platform supply vessels (PSVs) in the North Sea spot market as tonnage dwindled.
Brokers reported Enquest paying £14,500 ($19,100) per day for Nordic American Offshore's 4,200-dwt NAO Thunder (built 2013) over two weeks.
This is up from £4,000 just five days ago as fleet use hit 85%.
Six PSV fixtures have been reported over the last two days.
