The upcoming IMO Marine Environment Protection Committee (MEPC 73), on 22-26 October, is expected to approve ship implementation planning guidance as well as best practice guides for Member States/coastal States and for fuel oil suppliers.
The MEPC is also expected to adopt a complementary MARPOL amendment aimed at supporting implementation of the 1 January 2020 0.50% limit. This amendment will prohibit the carriage of non-compliant fuel oil - unless the ship has a scrubber fitted.
Most ships are expected to utilize new blends of fuel oil which will be produced to meet the 0.50% limit on sulphur in fuel oil. Currently, the maximum sulphur limit in fuel oil is 3.50% globally (and 0.10 % in the four ECAS: the Baltic Sea area; the North Sea area; the North American area (covering designated coastal areas off the US and Canada); and the United States Caribbean Sea area (around Puerto Rico and the United States Virgin Islands)).
The sulphur regulation also allows for ships to meet the requirement by alternative means, such as scrubbers, which allows the ship to continue using high sulphur fuel oil as the scrubber “cleans” the emission on the ship.
