Methanol Fuel Tank Sizing, Range & Cargo Space Tool
Estimate required methanol fuel mass, gross tank volume,
installed endurance, sailing range and the additional ship-space
footprint versus a conventional reference fuel. Advanced mode
separates sea and port consumption, tank heel, pilot fuel,
installation-space allowances and voyage fuel economics.
Currency selector changes display only. No exchange-rate conversion is performed.
Tank Sizing
Consumption, reserve, fill limit, heel and methanol density
Endurance & Range
Installed usable fuel translated into planning days and nautical miles
Cargo-Space Impact
Compare methanol tank-system footprint with a reference-fuel installation
Voyage & Methanol Consumption
Simple mode treats the entered voyage as continuous sea operation.
Daily methanol consumption should be a vessel-specific planning value.

Model approach:
required methanol mass equals planned voyage consumption plus
the entered operational reserve. Deliverable tank volume is
based on maximum fill minus unavailable heel. Required gross
tank volume equals required mass divided by methanol density
and deliverable tank fraction. Installed planning endurance
divides installed deliverable methanol by sea consumption
including reserve. The reference-fuel comparison uses separately
entered consumption, density, reserve and tank assumptions rather
than assuming equal engine efficiency.
Planning estimate only.
Actual methanol tank sizing depends on vessel design, machinery
efficiency, fuel specification, tank arrangement, structural limits,
stability, trim, hazardous-area classification, segregation,
ventilation, cofferdams, piping, fuel preparation, bunkering
arrangements, class requirements, statutory requirements and
operational reserve policy. The displayed ship-space difference
is an indicative volumetric comparison and does not mean that the
same quantity of revenue cargo space will necessarily be lost.
Density, heating value and consumption should be replaced with
vessel-specific design or operating data before engineering,
procurement or commercial decisions.
