Which equipment is used to provide a quick, temporary seal around a hole using mechanical fasteners and a patch?

• A. Patch plate and fasteners or canvas patch with bolts.
• B. Welding a solid plate directly to hull without bolts.
• C. Using silicone sealant alone.
• D. Drilling random holes to relieve pressure.

Answer: (A)

When you need a quick, temporary seal around a hole using mechanical fasteners and a patch, you rely on a patch plate and fasteners or a canvas patch secured with bolts. This setup provides an immediate, sealable cover over the opening by clamping a patch to the hull around its edges, distributing the load and holding against incoming water without requiring heat or welding. It’s portable, can be deployed in cramped spaces, and can be removed later for a more permanent repair. Welding a solid plate directly to the hull isn’t as fast or practical for a temporary fix at sea; it requires hot work, more time, and a more permanent alteration of the hull. Silicone sealant alone isn’t strong enough to withstand water pressure and dynamic loads. Drilling random holes would only create additional leaks and compromise hull integrity.
