Four in five OSV market players are expecting either a slight or significant rise in vessel use over the next year.
The figure was revealed by Clarksons Platou Securities, which quizzed 1,700 owners and charterers in March and April.
"Expectations for near-term vessel demand have risen markedly relative to our August 2017 survey," it said.
Last year's figure for a rise in utilisation was 40%, compared to 80% this year.
