BUNKER PLANNER

Plan fuel and reserves

Build a sequence of voyage legs, estimate grade-specific burn, and check remaining bunkers after each leg.

Voyage Estimator
01

Starting bunkers & prices

Enter actual ROB and your planning price for each grade. Reserve is a planning threshold you set.

02

Consumption rates

Enter your vessel’s daily consumption in each operating mode. ECA rates are explicit assumptions.

Primary fuel MT/dayDistillate MT/day

A zero primary-fuel ECA rate is a visible starting assumption; change it to match your operating plan. ECA distance is a partial map screening result, not a fuel-switching instruction.

03

Voyage legs & bunker stems

Select ports to prefill mapped distance and ECA miles, or enter verified values manually. Stems are received before sailing each leg.

Planning estimate only. The route graph may omit harbor connections, ECA coverage is partial, and proportional ECA sea days assume constant speed. Verify routes, regulations, fuel availability, weather margin, and vessel-specific consumption independently.
