Which type of fuel testing determines the total weight and the draft of the ship?

Prepare for the Engineman EN A School Test 1. Utilize flashcards and multiple choice questions with detailed explanations to boost confidence and readiness for the test.

Fuel weight comes from density times volume, and a ship’s draft is determined by the total weight it carries in the water. A specific gravity test tells you how dense the fuel is relative to water, which lets you convert the fuel’s volume in a tank into its actual weight. Once you know that weight, you can see how loading or burning fuel will change the ship’s displacement and thus its draft. The other tests measure properties that affect how the fuel behaves or how safely it can be stored and handled—viscosity relates to flow, flash point to flammability, and cloud point to cold-weather behavior—not the mass or the draft impact. So the specific gravity test is the one that directly links fuel quantity to the ship’s draft.
