Question 23Safety & Environmental - QMED

The correct answer is D) apply a patch of sheet packing backed by a strong back or shoring. This is the correct method because it provides a temporary but effective way to seal a crack in the hull without requiring extensive repairs. The sheet packing creates a seal over the crack, while the strong back or shoring provides the necessary structural support and pressure to hold the patch in place. This approach is commonly accepted as a safe and practical way to temporarily address a hull breach until permanent repairs can be made. The other options are not recommended. A) shoring up the crack with welded braces would require hot work that may not be feasible or safe in certain situations. B) drilling holes at each end could further compromise the integrity of the hull. C) tack welding a doubler plate may not create a reliable seal and could lead to additional damage.
