Question 62 GLI05 - Master or Mate of LT 200 GRT

The Correct Answer is C **Why Option C is Correct:** The primary objective of shoring in damage control (specifically for a damaged bulkhead) is **structural stabilization**. When a bulkhead is damaged, it loses its structural integrity and risks collapsing, potentially enlarging the damage, causing progressive flooding, or endangering personnel. Shoring applies temporary bracing (usually wooden timbers) to support the weakened structure and hold it firmly in its *current* damaged position, preventing further movement, deformation, or collapse until permanent repairs can be made. **Why Other Options Are Incorrect:** * **A) To force the warped, bulged, or deformed sections back into place:** Shoring is generally not used as a jacking mechanism to actively straighten or force sections back into their original position. Attempting to force severely damaged metal structures back into place using emergency shoring is often ineffective and can lead to immediate collapse or further tearing/enlargement of the damage. Its function is defensive, not corrective. * **B) To make a watertight seal at the damaged area:** Making a watertight seal is typically achieved through plugging, patching, or applying specialized sealants directly over the breach. While shoring is often used *in conjunction with* patching to hold the patch in place against water pressure, the shoring itself does not create the seal; its objective is structural support. * **D) To withstand subsequent additional damage:** While stabilizing the area might indirectly help the structure tolerate minor subsequent stress, the immediate goal of damage control shoring is to deal with the *existing* damage and prevent it from worsening. Designing temporary shoring to proactively withstand entirely new, unpredictable, and significant additional damage (like a second explosion or major impact) is not the stated objective; the focus remains on stabilizing the structure currently compromised.
