cruising range for various routes and to make
the most effective use of cargo space. Further-
more, ClassNK is scheduled to conduct a risk
assessment (HAZID; Hazard Identification Study
Note) to confirm that no unacceptable risks exist
at the basic design stage and to identify items
to be considered in the detailed design, which
will incorporate safety measures fully taking into
account the toxicity of ammonia, and other fac-
tors.
Amid the trend toward decarbonization, global
interest in ammonia as a next-generation clean
energy source is growing, and the maritime
industry is accelerating its efforts to utilize
it strategically as a fuel. As expectations for
ammonia as a marine fuel increase, MOL and
Mitsui will promote the expansion of net-zero
emission ocean-going vessels and play a role
in society’s overall efforts to achieve decarbon-
ization.
