Intercargo is “extremely worried” that not enough IMO 2020 compliant fuel is available for testing.

The association said 0.5%-sulphur fuel is available at only a limited number of ports and “under unfavourable terms” at the moment.

It said that presents a safety concern for bulkers because many shipowners will not get the chance to test the new generation of low-sulphur blended fuels, with just five months left until the regulations come in.
