Type 926 (Rescue Ship)
The Chinese navy has a long history of equipping submarines. There have been serious submarine accidents such as the 361 submarine shipwreck . The Chinese Navy has always attached great importance to submarine support tasks. It has served multi-type submarine support and supply ships. In recent years, it has been one of the countries with the most advanced submarine rescue capabilities through independent research and development and introduction of international advanced technology and equipment. Among them, the Type 926 is the latest submarine support ship developed by the Chinese Navy after the 21st century.
The 926 submarine support ship is a submarine support ship that was commissioned in early 2010 in China. With a displacement of 9,500 tons, the rear winch unit can lower the rescue capsule to a depth of 300 meters and rescue 18 crew members from the submarine. This winch unit also controls the LR7's new miniature rescue submarine. China has purchased at least one LR7 rescue submarine from the UK with a deadweight of 25 tons. The submarine can dive to a depth of 500 meters and can work continuously for four days under water.
In 2008 Guangzhou Shipyard International Company received instructions to build 926 submarine support ship (AS - Qian-Ting Zhi-Yuan Jian), The first ship Ocean Isle ship (AS864) had a naming ceremeony in 2010. After the delivery of the North Ship to a large defense service, the second ship of the type of ship, the Liugong Island Ship (AS865), was launched in early 2012 and was delivered in the first half of 2013. The third Long Island Ship (AS867) was Launched in 2012, and after the pre-judgment was in service in the second half of 2013.
This type of ship has a displacement of up to 9,500 tons. The winch cable can be used to hang a diving bell or a lifeboat to a depth of 300 meters. The design of the boom and the winch is also suitable for hanging a 25- tonne LR7 lifeboat. Since the names of the three submarine support ships are all within the jurisdiction of the North Ship, in theory, they should all be delivered to the North Ship. However, because the South Ship and the East Ship are also in urgent need for the advanced submarine rescue ships, the investigation of the Liugong Island ship The East Ship and the Long Island Ship are highly likely to hand over to the South Ship, although this distribution does not meet the norms of the naming regulations.
In addition, based on the advanced performance of this type of support ship, it should be mass-produced. At least 2 to 3 ships must be deployed in each fleet to maintain one maneuver at any time to meet the increasingly frequent seafaring requirements of the Chinese submarine. At present, there is no level of NATO named this type of ship. However, this type of ship has been in service, and it should be given the level of the big head at this time. It is quite similar to the name of the ship in China.
The 926 submarine support ship is a submarine support ship that was commissioned in early 2010 in China. It is currently at the advanced level in the world. With a displacement of 9,500 tons, the tail winch unit can lower the rescue capsule to a depth of 300 meters underwater, and rescue 18 crew members from the submarine at a time. This winch unit also controls the LR7's new miniature rescue submarine. China has purchased at least one LR7 rescue submarine from the UK with a deadweight of 25 tons. The submarine can dive to a depth of 500 meters and can work continuously for four days under water.
The first newest integrated submarine rescue ship, with a displacement of more than 7,000 tons, was commissioned in early 2010. Its main task is to carry out submarine rescue and rescue for the wrecked submarine, perform various diving services and assist in salvage operations, as well as rescue the wrecked surface ships and rescue the drowning personnel.
The ship adopts electric propulsion system to realize stepless speed regulation and excellent control performance. It can cooperate with the full-rotation rudder propeller to move the position and angle freely, which is convenient for rescue.
The ship evolved from a single anchoring position in the past to anchoring and dynamic positioning. The power positioning system adopted for the first time consists of a control system, a sensor, a power supply system, a rudder propeller device, and a bow thruster. It can be positioned in all directions below 4 sea conditions and 2 water flows. The system can maintain the ship position and accurate target tracking, and the standard deviation of the fixed-point control accuracy and the standard deviation of the track-preserving accuracy are all at a high level.
Search, detect, and route the job site. After receiving the rescue and rescue mission, the "Ocean Island" can quickly deploy the rescue equipment and related equipment and materials such as deep-dive lifeboats to the submarine wrecked sea area, and initially determine the location of the wrecked submarine, above the wrecked submarine. Dynamic positioning or anchoring positioning is carried out nearby, and a work site is arranged. After the completion of the installation, further determine the specific location of the submarine, determine the rescue operation mode and operating procedures. Second is the support for potential life.
Support for submersible is the main way to rescue life. Under the assistance of divers or working remote-controlled submersibles, the submarine that is sitting on the bottom of the sea is ventilated and ventilated; transporting food, tools, medicines, etc.; providing emergency lighting for submarines Supply air to the submarine main ballast tank, so that the boat floats and rescues the crew from the boat. In order to increase the depth of operation and extend the working time, and improve the efficiency of underwater operations, the "Ocean Island" is equipped with a 300-meter saturated diving system for shallow saturated diving and patrolling diving operations over 300 meters. It can also be used for mixed gas and air diving operation and shallow water atmospheric pressure observation below 300 meters.
In the "Pacific Rim-2016" joint military exercise, "Long Island" showed its talents and quickly searched the simulated submarine rescue platform deployed by the United States to accurately complete the underwater docking. In September this year, the "Long Island" carried the LR-7 deep dive lifeboat. Participated in the Sino-Russian "Sea Joint-2017" submarine rescue exercise, and successfully carried out the actual boat docking rescue with the foreign submarines for the first time.
