Question 171Safety & Environmental - Assistant Engineer70% to pass

Your vessel has run aground and upon taking fuel oil tank soundings, you find that a fuel tank level has increased. You therefore should suspect _______________.

AI Explanation
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 indicates that there is an ingress of water into the fuel tank, likely through a crack or breach in the hull portion of the tank. This would allow seawater to enter the tank, causing the fuel level to rise. The other options are incorrect - bad fuel or condensation would not cause the fuel level to increase, and a contamination from the salt water flushing system would not directly impact the fuel tank level.
