The struggle for survivability of a vessel.Sealing of holes (1989)

A simulator for practicing the skills of eliminating holes on the ship.

Various methods of sealing holes are being worked out.

Sealing the hole with a hard plaster and a wooden beam.

The beam should be installed perpendicular to the patch.

The preliminary split should not be too weak, then after precipitation the patch will not slip off the hole.

When working with a sliding metal stop, it is important to choose its initial length correctly.

If it is insufficient, you need to transfer the stud to another hole and squeeze the patch by rotating the pressure nut of the threaded connector.

The angle profile clamp is more compact and convenient to use.

First of all, it is necessary to ensure reliable fastening of the hooks on the frames of the vessel.

When installing the patch, make sure that its center is located strictly opposite the clamping screw of the clamp.

If the hole has the edges bent inwards, a hook bolt with a crossbar and a box patch are used.

The bolt with the crossbar is wound into the hole, while it is important that the crossbar is securely pressed against the side from the outside.

Now, holding the bolt in tension, put on a box-shaped patch and tighten it with a locking nut.

Small holes can be sealed with wooden stoppers.

When sealing large holes in the hull and bottom of the vessel, various types of plasters are used.

The loaded and straightened patch falls overboard.

At the same time, it should be remembered that even if the patch completely hits the hole, water filtration may occur due to the loose fit of the patch to the board.

It is eliminated with the help of careful compression of the patch and an additional selection of sheets, suspenders and podkil ends.

The crack in the case is being brewed.

The ends of the crack are drilled, the metal edge is cleaned.

The seam is being welded.

When installing the doubler, it is necessary to thoroughly clean the side in the welding places.
