Question 258Safety & Environmental - 1st Asst/Chief

The correct answer is D) a crack in the hull portion of the fuel tank. If a fuel tank level has increased after the vessel has run aground, it is an indication that seawater is entering the fuel tank through a crack or breach in the hull. This would cause the fuel tank level to rise as the seawater displaces the fuel. The other options, such as condensation, contamination from a saltwater flushing system, or bad fuel, would not result in an increase in the fuel tank level. Inspecting the fuel tanks and hull for any cracks or damage is the appropriate course of action in this situation, as a breach in the hull could pose serious safety and environmental concerns that need to be addressed.
