Norway's Eidesvik Offshore has made it back into the black after a better summer for its spot ships.
The pre-tax profit in the third quarter was NOK 32.3m ($3.94m), from a loss of NOK 143.3m a year ago.
The result was affected by currency changes related to foreign-currency debt, while revenue dipped to NOK 157m from NOK 201.4m.
It said platform supply vessels (PSVs) had experienced a good summer season in the spot market, with "reasonable" rate levels and utilisation.
