The Lloyd’s Register’s Maritime Decarbonisation Hub has conducted risk assessment workshops indicating the necessity for a significant revamp in seafarer training as the maritime industry transitions to zero and near zero GHG emission fuels. The workshops, in collaboration with the Maritime Just Transition Task Force (MJTTF) and the United Nations Global Compact Ocean Stewardship Coalition, resulted in the production of a report highlighting the need for a new baseline training framework to equip seafarers with the required skills to handle ammonia, methanol, and hydrogen as marine fuels safely. The challenges and hazards presented by these green fuels such as toxicity, flammability, and safety requirements were discussed extensively during the consultations involving over 100 stakeholders. The current Standards of the Training, Certification, and Watchkeeping for Seafarers (STCW) Convention do not provide guidelines or competency levels specific to these green molecules, necessitating the development of detailed competency standards and training frameworks. Challenges with each fuel type were addressed - like ammonia's toxicity requiring comprehensive training on emergency response procedures, methanol's high flammability necessitating new fire detection methods, and hydrogen's need for enhanced fire safety systems. The MJTTF training project aims to work on drafting and implementing detailed training materials to upskill and reskill seafarers who will be working with these fuels. The project is backed by the IMO through technical cooperation funding and Lloyd's Register Foundation, with the upcoming roll-out of the Instructor Handbook set for May 2025 at MTCC Asia, led by the World Maritime University. The overall goal is to ensure safer maritime fuel usage and enhance seafarer competency in handling ammonia, methanol, and hydrogen.
