Diving and underwater engineering work at neftegazopromyslovy. Film 2nd (1987)

Oil rigs in the sea.

The engineer examines the drawing of the tower.

As a result, an order is drawn up-a task for diving and underwater technical work.

The captain of the diving vessel ensures the implementation of court-wide measures to ensure diving descents and reliable installation of the vessel over the object of work.

Warning signs are posted.

Monitoring of the place of work is organized.

The temperature of air and water, the speed of the current, the depth of the sea in the area of descent are recorded.

All these data are recorded in the ship's log and the diving log.

A warning signal appears on the mast of the vessel.

The head of the descents conducts an instruction.

A working, providing and insuring divers are appointed.

A working diver checks equipment, performs descent and performs work at depth.

The provider is responsible for the maintenance of the working diver.

The insurer must be ready to immediately descend into the water to assist the working diver, he also maintains telephone communication with him.

The foreman of the diving station is responsible for the general preparation for underwater descents.

He, as a rule, is the head of descents.

The decompression chamber is checked once a day before the start of work.

After the check, an entry is made in the log.

Before the descent, the working and insuring diver make a check of their equipment.

The results of the inspection are recorded in the diving log.

Compressed air reserves are checked.

A working boat goes overboard, a diving ladder is installed.

The trigger end must be firmly fixed on board the vessel.

Daily medical examination.

A strict procedure for dressing the diver is followed.

The provider must not let the signal end out of his hands from the moment it is fixed on the diver until the diver returns to the deck of the vessel.

Report on the readiness of the descent.

Having received permission, the provider gives the command to the diver to start the descent.

The descent time is counted from the moment the diver is included in the device.

After going under the water, the diver must check the tightness

equipment.

When descending, the diver must hold on to the trigger end.

On the ground, the diver should look around to check the ends and hoses.

The provider holds the hoses so as to feel the diver, but not to interfere with him.

The diver must report all changes in the environment, his actions, movements by phone.

The doctor and the head of the descent determine the decompression mode.

For the safety of the diver, decompression in the water is carried out on special diving gazebos.

The command to finish the job.

The diver swims to the end.

The diver climbs up to the first gazebo.

The diver's ascent from a depth of more than 12 meters takes place with stops for decompression.

On command, the diver moves to the next gazebo.

The provider selects the ends and hoses.

It is necessary to quickly undress the diver and place him in the decompression chamber under pressure equal to the last stop.

The total time for these actions should not exceed 6-7 minutes.

Performing deep-sea work requires careful preparation.

The method of short-term dives.

With this method, the bell with divers is sealed at atmospheric pressure.

A cartoon explaining the work on this method.

The method of prolonged stay under water.

Divers live for a long time under pressure equal to the pressure at the working depth.

After the completion of the work or the expiration of the deadline for the divers to stay in saturation mode, one decompression is carried out.

The method of long stay.

The head of the works coordinates with the head of the descents the outfit-task.

Preliminary preparation begins.

Respiratory mixtures of the desired composition are being prepared.

The reserves of the respiratory mixture are checked.

All systems of the deep-sea complex are being checked.

Pressure chambers and diving bell are checked for tightness.

A medical examination of aquanauts is being carried out.

The head of the descents together with the diving doctor develop a work plan.

They also instruct divers.

The first post is working divers.

The second post serves the deep-water complex support systems and provides compression and decompression of aquanauts in the pressure chamber.

The third post is responsible for the descent and ascent of the bell.

The fourth post is in charge of all the electrical equipment of the diving complex.

The fifth post is responsible for the diving tool.

At the command of the work manager, a final check of all systems and mechanisms is carried out.

The bell is connected to the pressure chamber.

Checking the pressure chamber, regeneration system.

Disinfection of all equipment is mandatory.

Final medical examination and sanitary treatment.

The pressure in the pressure chamber begins to increase.

The first descent into the water is allowed after 10-12 hours after the end of compression.

The transition of divers to the diving bell.

The head of the descents gives instructions on how to carry out the work.

Working check of the bell.

In the airlock compartment of the pressure chamber, divers wear diving suits.

The exit of the divers to the bell to check the diving equipment.

The bell is lowered to the place of work.

For 15-20 meters to the ground, the speed decreases.

When the set depth is reached, the inner cover of the lower hatch opens.

Aquanauts are getting ready to go out to do the job.

At the command of the head of the descent, the first aquanaut begins work.

Aquanauts on the TV screen.

The providing aquanaut is at the bell, he monitors the actions of the worker and helps him.

The bell operator is ready to provide immediate assistance to the divers and monitors the readings of the instruments.

The work is over, the aquanauts enter the bell.

The hatch is sealed and the bell rises.

The bell is docked with the pressure chamber.

Divers move into the airlock compartment.

The staff of the post responsible for the operation of the life support system and the diving doctor work around the clock.

Aquanauts live according to a special daily routine.

A working watch can last 10-15 days.

Divers on vacation are engaged in the simulator and play chess.

After completion of the work, decompression of the divers is carried out.

Decompression is over.

Divers must stay in the pressure chamber for another hour and at least a day on the ship under the supervision of a doctor.

Divers come out of the pressure chamber.

The ship is returning to base.
