Shipping is changing, with more vessels being built to run on alternative fuels such as LNG, methanol and ammonia. In fact, last year these vessels accounted for 38% of the gross tonnage of new ships ordered worldwide.

For seafarers, this brings new challenges and career opportunities.

Each fuel has different risks. LNG must be stored at extremely low temperatures, methanol is toxic and flammable, while ammonia is dangerous if inhaled. Even experienced seafarers need additional training to work safely with these fuels.

Manuals and online courses are useful, but practical training is essential and crews must understand their vessel's fuel systems, recognise hazards and know how to respond to leaks and emergencies. The International Maritime Organization (IMO) has also issued new guidance on training for alternative fuels and technologies.

As more alternative-fuel vessels enter service, seafarers with the right skills and qualifications will be in demand. If you're interested in these opportunities, speak to your crewing manager about the training you may need.

New fuels need new skills, and making sure crews are properly trained is just as important as investing in the technology itself.
