Owners of North Sea anchor-handling tug supply (AHTS) vessels have been able to capitalise on sustained tight ship supply to boost spot rates.
Norwegian broker Seabrokers said vessels have been scarce after the tonnage pool shrank during the downturn due to stacking, sales and scrapping.
"It has long been recognised that the limited number of vessels trading the spot market has left charterers exposed to rapidly rising rates but that scenario was very evident in September," said the broker.
