Question 58 RVR03 - Mate of LT 500-1600 GRT

The Correct Answer is D **Why Option D is Correct:** Shoring is a temporary, emergency structural reinforcement technique used primarily in damage control aboard ships (or in buildings). The immediate objective of shoring a damaged bulkhead (wall) is to maintain the structural integrity that remains. By bracing the area—typically using wooden or metal shores (posts) and wedges—the crew prevents further movement, collapse, or expansion of the damage caused by pressure (like hydrostatic pressure from flooding), shock, or external forces. The goal is to **support and hold the structure in its current, damaged position** until permanent repairs can be made or until the danger has passed, thereby preventing the damage from worsening. **Why the Other Options are Incorrect:** * **A) To make a watertight seal at the damaged area:** This is the objective of patching or plugging, not shoring. Shoring provides structural support; it does not stop water ingress. * **B) To force the warped, bulged, or deformed sections back into place:** Shoring is explicitly *not* meant to reverse the deformation. Attempting to force the damaged structure back into its original position is dangerous, risks immediate structural failure, and is generally impossible under emergency conditions. Shoring aims to stabilize the structure as it currently stands. * **C) To withstand subsequent additional damage:** While shoring makes the structure more resilient than it was immediately after the initial damage, its primary purpose is stabilization against current stresses (like water pressure or gravity). It is a temporary measure designed to prevent the existing damage from spreading, not necessarily to prepare the vessel to withstand a second major impact or catastrophic event. Option D describes the immediate and direct engineering objective of the procedure far more accurately.
