Question 182Safety & Environmental - Assistant Engineer

The correct answer is D) apply a patch of sheet packing backed by a strong back or shoring. This is the correct method for temporarily sealing a crack in a vessel's hull. Applying a patch of sheet packing (such as rubber or other waterproof material) and backing it with a strong back or shoring provides a quick and effective way to prevent further water ingress through the crack. This temporary solution allows the vessel to safely reach port for permanent repairs, without requiring more complex measures like drilling holes or welding. The other options are not recommended for temporary hull repairs. Drilling holes could potentially weaken the hull further, while welding and shoring with braces may not provide a reliable, waterproof seal in an emergency situation.
