In the area of work of divers, portholes, kingstons and drain holes are closed.

The hydroacoustic equipment is de-energized.

It is forbidden to use equipment that extends beyond the enclosure.

The members of the team for the transfer of the end of the profile are determined.

A supervisor is appointed to move the podkilny end and communicate with the divers.

It is necessary to fix the propeller shaft of the main engine and the blades of the adjustable pitch propeller.

Stop thrusters and rudders.

At the control panel of the main engines and thrusters there is a watch mechanic.

Warning signs are posted on the remote control, they warn against accidental actions.

The work carried out is recorded in the machine log.

The foreman of the diving station must make sure that all work has been carried out.

Signal A is being raised on the ship, according to the international signal system.

Lighting of the divers' place of work at night.

Signal A is given by three lights.

After completing the set of measures, the captain and the chief mechanic sign a work permit.

A tear-off coupon is a permit for diving descents.

The beginning of diving operations is recorded in the logbook.

Divers go under the water.

Before the descents began, the foreman distributes duties among the divers and instructs everyone.

This is recorded in the diving log.

Each descent begins with checking the equipment for tightness and buoyancy.

A cartoon explaining the safety requirements.

The diver moves to the keel of the vessel and back.

Two divers can work at the bottom end, each on its own side.

It is forbidden for divers to cross the keel.

For divers to work on a vessel without mooring, several conditions must be met.

The diver determines whether the paint is firmly attached to the metal and where it is not at all, the welds are carefully examined.

A cartoon explaining the defects of the cladding.

A dent on the hull of the vessel, the diver measures its parameters.

The hole, the diver measures its parameters.

Cartoon frames alternate with frames of real defects.

Ultrasonic thickness gauge used to check the wear of the outer skin.

The use of a video camera for underwater inspection.

According to the results of the diving inspection, repair reports are compiled.

The technology of the next stage of work, underwater ship repair, is being developed.

The boat with divers goes to the base.
