Marine Fuel Oil Quiz

According to SOLAS, what is the minimum flashpoint for all heavy fuel oil to be used onboard vessels?

• 50°C

• 60°C

• 70°C

• 100°C

A higher Calculated Carbon Aromaticity Index (CCAI) number indicates which of the following?

• Superior ignition quality

• Higher viscosity

• Inferior ignition quality

• Lower sulphur content

As per MARPOL regulations effective from January 1, 2020, what is the maximum sulphur content for HFO in most sea areas?

• 3.50% m/m

• 1.50% m/m

• 0.50% m/m

• 0.10% m/m

Which of the following is described as a high-grade distillate fuel oil that does not require any pre-heating for usage?

• Heavy Fuel Oil (HFO)

• Marine Diesel Oil (MDO)

• Bitumen

• Residual Oil

The temperature below which a fuel ceases to flow is known as the:

• Flash point

• Pour point

• Ignition point

• Density point

According to ISO 8217:2010, the maximum limit for catalytic fines (Al+Si) for RMG and RMK category fuels is:

• 870 mg/kg

• 60 mg/kg

• 0.50% m/m

• 0.2% m/m

Which of the following is NOT identified by DNV GL as one of the most promising alternative fuels for shipping?

• LNG

• Methanol

• Hydrogen

• Compressed Natural Gas

What is a significant potential drawback of using LNG as a marine fuel despite its lower CO2 emissions?

• The release of unburned methane (methane slip)

• Higher sulphur oxide pollution

• The need for pre-heating

• Extremely high viscosity

What is the recommended practice for handling fuel during bunkering?

• Mix the new fuel with the old fuel to ensure consistency

• Always use the newly bunkered fuel first

• Bunker the 'new' fuel into empty tanks

• Consolidate old fuel into multiple small tanks

What is the primary purpose of an Emission Control Area (ECA)?

• To increase shipping traffic in designated zones

• To establish stricter controls to minimize airborne emissions from ships

• To set a global standard for fuel density

• To manage the price of low-sulphur fuel oil
