« Skandi Arctic"This is the latest diving support vessel, equipped with the latest technology. Diving support vessel " Skandi Arctic"built at the STX OSV shipyard in the Romanian city of Tulcea in 2009 by order of the Norwegian company DOF with one goal - to protect the lives of divers performing work at the bottom of the sea.

Diving support vessel " Skandi Arctic» has a complex of modern equipment systems aimed at carrying out dangerous and expensive work in the area of ​​oil and gas fields on the coastal shelves, annually bringing in millions of dollars in profit.

The team of divers who will be engaged in underwater work is delivered on board the vessel by helicopter. Upon arrival, an integral part of the group of divers is to undergo a medical examination to determine their suitability for diving. At the same time, the equipment of the decompression chamber is being checked on the ship, where the shift will spend the next three weeks in cramped conditions and complete isolation.

On a diving support vessel " Skandi Arctic“There are six such cameras at once. Each of them is a sealed cylinder with a diameter of 2.5 meters, which is filled with a mixture of high pressure to ensure the safety of people. The fact is that when carrying out underwater work at a depth of up to 130 meters, divers are forced to stay inside the chamber, since the human body cannot withstand the high pressure. In the decompression chamber, the pressure gradually increases and the body adapts to this environment within 5 days, allowing a person to breathe the mixture normally and not die.

Each decompression chamber is equipped according to the principle of a universal dormitory. For normal living conditions for divers, there are seats, a common toilet, and a shower. The cramped living space contains six beds, as well as space for entertaining and eating. But divers are forbidden to leave the chamber so as not to die from a sharp pressure drop. To do this, they are regularly monitored by several specialists through ten video cameras to ensure that there is no threat to the divers. Their computerized post resembles Mission Control. From here you can see literally every step of the people in the cell. Highly qualified operator-controllers do not lose their attention for a minute. Wherever divers are - in a decompression chamber or on the seabed - they always remain under close scrutiny. Cameras monitor them even when people go to the toilet, where water also descends under the control of operators. In a word, the team of controllers is fully responsible for the lives of divers.

The crew of the diving support vessel “Skandi Arctic” consists of 120 people, who are specialists in various fields and perform a common task - efficient and safe diving operations.

After a daily medical examination, divers are allowed to dive. Their next step is to move into a device called a diving bell, which will transport them from an isolated room on board to the seabed. The device is like an elevator. The diving bell is hermetically connected to the decompression chamber. There is a hole (shaft) in the vessel's hull through which the diving bell is lowered directly to the work site.

underwater work

A common job for divers is to replace rusty fasteners (bolts) in hard-to-reach areas of underwater oil or gas production structures. This operation in offshore companies is regular maintenance. But this work is not easy, since you have to work in conditions of limited access.

Once in the decompression chamber, divers find themselves in another world. Then the air injection process begins. Before starting to gradually increase the pressure in the decompression chamber, the tightness of the hatches and airlocks is checked. The air pressure gradually increases over three hours to prepare the body for the enormous pressure in the ocean depths.

The slow increase in pressure is not felt in any way, except for the voices of the divers - they become funny, like cartoon characters. The fact is that a mixture of oxygen and helium at a depth of hundreds will not be toxic in comparison with ordinary air, which is 80 percent nitrogen. So for three weeks the divers talk like Donald the duckling.

On one of the decks of the diving support vessel " Skandi Arctic» there are gas storage facilities where 40 thousand cubic meters are stored. m helium. This is enough to supply some circus with it for 100 years.

While divers are adapting to the ship's high pressure " Skandi Arctic"arrives at a point located above the underwater object. Thrusters at the bow and stern make it possible to easily remain in specified coordinates, deviating no more than 2 meters at wave heights of up to 5 m. During the descent of the diving bell, the vessel must remain motionless to avoid tension on the life support hoses.

When the ship takes position and the divers have completed adaptation, the underwater operation begins. On the loading deck, the diving bell is mounted above the decompression chamber, reminiscent of docking in outer space. Three divers enter the diving bell, and the device is lowered to a place where 30 years ago it was only possible in dreams, but now the process takes 3 minutes. The bell takes divers to depths where darkness reigns. They then leave the device and get to work. Two divers go to the object, and the third remains inside, belaying them. To avoid destruction, the diving bell hovers at a height of 2-3 meters above the object. Then, with the help of a crane, a container is lowered to the bottom, which contains the tools and spare parts necessary for carrying out dangerous work. With the container, physical contact with instruments is minimized, significantly reducing the risk of damage to wetsuits and life support lines. The work is carried out manually. Naturally, divers are in constant contact with the main post. At the control station, all bolt replacements performed are noted in a table so that none of them are missed, for which an unmanned underwater vehicle is lowered to the bottom. The shift of one diver lasts 6 hours.

Life support for divers at the bottom is carried out using individual hoses. Three hoses are supplied on the holding cable at once - electric for illumination and operation of video cameras; water heated to 30 degrees Celsius flows through the water hose into the lining of the wetsuit; oxygen hose through which the life-giving mixture is supplied.

Numerous specialists on board the ship and modern life support systems make it possible to work in dangerous conditions, but no technology can replace the mutual assistance of people. Without special training and mutual assistance, the chances of surviving at the bottom are negligible. In cold, deep water, a simple task becomes an extremely complex operation.

Having finished their work, the divers return to the bell. Within three minutes they are brought back on board the ship." Skandi Arctic" At the exit from the shaft, the diving bell is connected to the decompression chamber. There, divers take a shower, have dinner and rest while waiting for the next shift.

Food is delivered in an interesting way and also without breaking the seal. The food is left in the window, which is closed on both sides. After the operator makes sure that the domestic window is hermetically sealed, the divers open it from the other side. Another important task in the decompression chamber is the disposal of digestive products without depressurization. The solution was a powerful descent system with several airlocks controlled from a central station.
After several days of maintenance work, the underwater operation is completed. Then all divers, for five days, without leaving the decompression chamber, undergo the decompression process, and the vessel " Skandi Arctic"at this time it can proceed to the port or to another facility. After leaving the chamber, the threat to the divers' lives still remains, so medical personnel monitor the divers throughout the day.

Divers perform one of the most dangerous jobs on the planet, so after diving they need rest, and the diving support vessel " Skandi Arctic“does not know rest and is heading on a new voyage to ensure the normal operation of facilities supplying Europe with oil and gas.
