The Tokyo and Paris Memoranda of Understanding (MoUs) on port State control (PSC) have issued a joint letter to remind vessel owners and operators that inspections will be undertaken to ensure compliance with the new sulphur limit requirements on marine fuel oil, from 1 January 2020. The new requirements prohibit the use of non-compliant fuel from 1 January 2020 and the carriage of non-compliant fuel, for use on the ship, from 1 March 2020, unless the ship is fitted with an Exhaust Gas Cleaning System (EGCS).
