The growing number of dual-fuel ships on the newbuilding orderbook is fuelling concerns over a shortage of crew members trained to work on vessels that use alternative fuels.

The worries come as shipping’s path towards decarbonisation drives the need to prepare the seagoing workforce for an industry powered by an increasingly complex array of fuels.

Clarksons data shows that 37.7% of the global orderbook is made up of vessels capable of running on alternative fuels, with most being built to run on LNG but others on LPG, methanol and other solutions.
