UK owner James Fisher has continued its tanker fleet renewal as profit rises.
The Tankships division produced underlying operating profit of £4.3m ($5.58m) to 30 June, up from £3.9m a year ago.
This was from revenue of £28.5m, against £27.4m in 2017.
"Tankships has continued to perform strongly with vessel utilisations in the first quarter, which is traditionally the weakest quarter, showing an improvement on 2017," it said.
