Hotel Service Unit 7 Q1 Quiz

Correct Answer:
B) The lowest temperature at which the fuel can vaporize to form a flammable mixture in air, measured in degrees Celsius (°C)

Explanation:
The flash point is the minimum temperature at which the vapors of a combustible liquid can ignite when exposed to a flame. For marine diesel oil, the flash point is typically expressed in °C and is an important safety parameter.

Correct Answer:
B) The fuel’s delivery temperature

Explanation:
The delivery temperature of the fuel is recorded to ensure that the fuel is handled and transferred at the correct temperature, which is important for both safety and fuel quality.

Correct Answer:
B) The resistance of the oil to flow, typically measured in centistokes (cSt)

Explanation:
Viscosity is a measure of a fluid’s resistance to flow. For marine diesel oil, viscosity is typically measured in centistokes (cSt), and it influences how the fuel behaves at different temperatures and how it flows through the fuel system.

Correct Answer:
B) The sulfur content of the fuel

Explanation:
The sulfur content is a critical piece of information included on a bunker delivery note because it is regulated to prevent environmental pollution. It ensures compliance with MARPOL regulations on fuel sulfur limits.

Correct Answer:
B) The mass of the oil per unit volume, usually expressed in kilograms per cubic meter (kg/m³)

Explanation:
Density is defined as the mass of a substance per unit volume, and for marine diesel oil, it is typically measured in kg/m³. It affects the fuel’s energy content and handling characteristics.

Correct Answer:
B) The volume of fuel delivered, usually measured in metric tons or cubic meters

Explanation:
The volume of fuel delivered is a key part of the bunker delivery note, as it provides the ship with an official record of the amount of fuel received during bunkering operations.
