Which method is recommended for sealing jagged holes in structures?

The recommended method for sealing jagged holes in structures is the box patch. This technique is effective because it provides a robust and stable way to cover larger and irregularly shaped openings, particularly in hulls or bulkheads where structural integrity is essential. The box patch method typically involves using a band of material (often metal) that is cut to shape and secured around the edges of the hole, providing a secure seal that can withstand internal pressures and stresses.

In situations where a rapid and strong repair is required, such as in emergency damage control operations, a box patch offers the versatility and reliability needed. It can be tailored to fit the specific dimensions and contours of the hole, ensuring a snug and effective seal that reduces water ingress or air loss.

While other methods, such as a jubilee patch or wooden plugs, may be useful in different contexts, they do not provide the same level of durability and security in sealing irregular or jagged openings compared to the box patch. Shoring, meanwhile, is primarily focused on providing support rather than sealing, making it less applicable for this specific purpose.
