Question 607 Deck Safety

70% to pass

Your vessel has run hard aground in an area subject to heavy wave action. Backing full astern failed to free her. Which action should be taken next?

A Flood empty tanks to increase bottom pressure and prevent inshore creep.
B Wait for high tide and then try backing.
C Continue backing to scour out the bottom.
D Shift weight aft to reduce the forward draft.
AI Explanation

The correct answer is A) Flood empty tanks to increase bottom pressure and prevent inshore creep. This is the correct action because increasing the vessel's bottom pressure by flooding empty tanks helps counteract the effects of heavy wave action that could cause the vessel to dig further into the seabed or "creep" further inshore. Backing full astern may have been unsuccessful due to the suction and force of the waves, so increasing the vessel's weight distribution is the next best step to free it from the grounding. The other options are incorrect - waiting for high tide (B) may not be practical or timely, continuing to back (C) could further embed the vessel, and shifting weight aft (D) would not address the issue of insufficient bottom pressure to overcome the wave forces.
