Early Warning on Global 2020 Sulphur Cap Compliance Publications Steamship Mutual Published: December 31, 2018 Contact author Download article pdf Image From the Paris MoU group: The Maritime Authorities of the Paris and the Tokyo Memoranda of Understanding (MoU) on Port State Control advise that they will start issuing a letter of warning from 1 January 2019 on the sulphur content of marine fuels during inspections in order to increase awareness of and to encourage timely compliance with the new requirements. The requirement of maximum sulphur content of 0,50% m/m for marine fuel oil will enter into force on 1 January 2020, which is known as the global 2020 sulphur cap. The implementation of the global 2020 sulphur cap will have considerable implications on ship operators, the fuel oil supply chain and the industry as a whole. For the purpose of facilitating smooth and consistent implementation of the global 2020 sulphur cap, the Paris and the Tokyo Memoranda will carry out a joint information campaign by issuing a letter of warning to ships during inspections from 1 January to 31 December 2019. The aim is to increase awareness of the ships’ crew and company on the matter and to remind and encourage compliance with Regulations 14 (*1,*2) and 18 of MARPOL Annex VI from 1 January 2020. The letter of warning will be issued to ships found not yet ready for compliance with the relevant requirements that will enter into force on 1 January 2020. The letter of warning can be read here.
