The study investigates marine engineering education on alternative fuels and hybrid propulsion regarding decarbonisation of shipping. A new course is proposed for maritime education and training subject to the IGF Code amendments to the STCW which lasts 14 weeks and 3 h per week. Competences at the STCW amendments for the persons who work on alternative-fuelled ships are taken into account while preparing the course topics. Each topic is paired with basic and advanced training competencies of the STCW amendments, compliance with the STCW is provided, the course topics and sub-topics are explained, and the duration of the course is determined. The need for updating the curriculum and the training of future seafarers is crucial to satisfying their ability to operate future ships. This study highlights the need for novel approaches and courses regarding the new future technologies for the traditional marine engineering curriculum.
