In response to the rapidly changing needs of the maritime industry and the imminent introduction of alternative new fuels, The Nautical Institute has taken the initiative to develop an independent training standard for the maritime education and training (MET) sector. The lack of official STCW requirements and the absence of significant operational data for novel fuels have prompted the Institute to step in and provide guidance. The Nautical Institute's Green Curriculum paper, published in August 2022, introduced the concept of a global harmonised training standard for seafarers related to novel fuels as an interim measure until official regulations are established. The Institute's focus on ammonia, methanol, and hydrogen as the main novel fuels stems from the impending need to train approximately 800,000 seafarers in the use of these fuels by the mid-2030s. Recognizing the elevated environmental and operational risks associated with these fuels, the Institute aims to ensure seafarers are not unprepared for the changes in the industry. Through collaborations with initiatives like the UN Global Compact Maritime Just Transition Task Force and the Maritime Technologies Forum, The Nautical Institute is actively involved in developing STCW and ISM Code standards to address the challenges posed by novel fuels. The training standard provided by The Nautical Institute does not prescribe specific content but offers advice for training centers to develop their own course materials tailored to their needs. By making the standard freely available online, the Institute prioritizes the best interests of seafarers and the industry's environmental and operational safety. The focus on preparing seafarers for the bulk transportation of novel fuels reflects a proactive approach to mitigating risks and ensuring a smooth transition towards de-carbonizing shipping. With the increasing orders for alternative-fuelled vessels and the imminent need for training, The Nautical Institute's initiative serves as a crucial step in guiding the MET sector through the challenges of adopting novel fuels and adapting to evolving technologies.
