- A vessel has bunkered 300 tonnes of diesel fuel. Given that the average combined sea power load of the vessel is 3000 kW and with a stated specific consumption of 0.35 kg/kWh, calculate EACH of the following:
(a) the daily fuel consumption of the vessel;(4)
(b) the safe steaming range of the vessel at a speed of 18 knots.(6)
Given Data
- Fuel bunkered = 300 tonnes = 300,000 kg
- Power load = 3000 kW
- Specific fuel consumption (SFC) = 0.35 kg/kWh
- Speed = 18 knots
- 1 day = 24 h
(a) Daily fuel consumption
✅ Answer (a): 25.2 tonnes/day
(b) Safe steaming range
✅ Answer (b): Safe steaming range ≈ 5140 nautical miles
