Longer-than-expected scrubber installation times have become a headache for shipowners.

The only cure, according to industry experts, is to prepare well in advance and to coordinate with scrubber makers, shipyards, classification societies, and perhaps, even other shipowners.

DNV GL suggests that more than 3,000 vessels have been scheduled to have exhaust gas cleaning technology installed by the end of December, with shipowners seeking to take advantage of cheaper high-sulphur fuel oil (HSFO) as the IMO 2020 rules come into force on 1 January.
