- 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)
CHIEF ENGINEER Unit 17 FUEL CONSUMPTION Q1
- A vessel has bunkered 250 tonnes of diesel fuel of which 10% is assumed to be unpumpable. The average combined sea load of the vessel is 2800kW with a stated specific consumption of 0.35kg/kWh at a speed of 18 knots.
Calculate EACH of the following:
(a) the daily fuel consumption of the vessel;(4)
(b) the safe steaming range of the vessel.(6)
CHIEF ENGINEER Unit 17 FUEL CONSUMPTION Q2
9.(a) List FOUR factors that must be taken into consideration when determining the voyage requirements for a large motor yacht.(4)
(b) A vessel has a gross fuel capacity of 250 tonnes, 12% of which is unpumpable. The combined average sea power load of the vessel is 2700kW and the quoted specific fuel consumption, at this power load is 0.32kg/kWh.
Calculate the safe steaming range of the vessel at a speed of 15 knots.(6)
CHIEF ENGINEER Unit 17 FUEL CONSUMPTION Q3
- (a) A vessel has two main engines each with a working sump lubricating oil capacity of 750 litres and an average daily consumption each of 3.5 litres at full power.
Calculate the safe reserve lubricating oil requirements for a voyage of 2500 miles at a speed of 18 knots.(6)
(b) State TWO factors that will need to be taken into consideration when calculating the fresh water requirements for an extended voyage.(4)
CHIEF ENGINEER Unit 17 FUEL CONSUMPTION Q4
- (a) A vessel with two main engines each with a working sump lubricating oil capacity of 750 litres and an average daily consumption each of 3.5 litres at full power, has bunkered 1000 litres of oil.
Calculate the steaming range of the vessel when the engines are operated at full power delivering a speed of 15 knots to the vessel.(6)
(b) State the factors that should be considered when determining the fresh water requirements for a voyage.(4)
