According to the "Technology Daily" reported on the 17th, the world's largest horsepower unmanned remote-controlled submersible produced by CSR Times Electric's CRRC Essendi Marine Equipment Co., Ltd. has recently been launched in Shanghai. This is China CRRC M&A. After the British SMD company, the first set of working-level deep-sea equipment developed and produced in China. It can sneak into the 3,000-meter seabed, lift 4 tons of heavy cargo, and the power is up to 250 hp, which makes up for the short board on the deep sea operation equipment in China. Improve China's deep sea operations in marine salvage, seabed construction, etc.
There are two main types of unmanned remotely operated submersibles, one is observation level, mainly used for marine scientific research, etc., and the power is relatively small. The other type is work level, mainly used for marine salvage, submarine construction operations, etc. Relatively large, but generally does not exceed 150 hp. This newly developed unmanned remotely operated submersible is mainly used for emergency rescue, search and salvage operations such as sinking of deep seawater, and can also be applied to marine deepwater projects. Auxiliary work, etc. It is the most powerful unmanned remote-controlled submersible in the world. The system power is 250 hp, which is equivalent to the power of a BMW X6. The submersible is not big, its weight is only 5 tons, but its strength is very large. With its powerful power, it can penetrate the seabed of 3,000 meters and easily lift 4 tons of heavy objects. Its advent, can further enhance China's deep sea operation capability in marine salvage and seabed construction.
It is reported that although there are many countries on the earth with observation-level deep-sea unmanned remote-controlled submersibles, the core components of the observation-level deep-sea unmanned remote-controlled submersibles are underwater propulsion and underwater camera systems. The size and weight of the body are small and the load is relatively low. Low, low system capacity and reliability requirements, generally only used for scientific exploration purposes. For example, the 'Zhenlong' manned deep dive scientific research equipment is a typical observation level equipment.
The work-level submersible is used for underwater fishing, underwater construction and other demanding applications, large size, with underwater manipulators, hydraulic cutters and other work tools, requiring more power, more precise remote control and more Reliable underwater positioning and operation capability, the system is very difficult to implement. Previously, China had a short board in deep-sea robots, and the technology could not meet the market demand. Before the acquisition of British SMD by CZ Zhuzhou, the Shanghai Salvage Bureau in 2014 British SMD has ordered deep-sea robots that can operate in the deep sea of 6,000 meters.
According to the news on July 17th, Yan Yun, deputy general manager of Shanghai Chome Essendi Marine Equipment Co., Ltd., said in an interview with a reporter that compared with the same type of products, the 3,000-meter heavy-duty work level of the downline The advanced nature of ROV is that it can realize the flexible operation of underwater action by viewing the display screen in the operating cabin of the deck, and the operation signal is transmitted in real time without time error. When working underwater, if the visibility is high, the visible range can be reached. 3 meters. If the definition is not high, it can be kept at about 1 meter in normal condition. It can also be detected and positioned by using sonar. It is worth noting that the accuracy of the submersible is very high. According to Yan Yun, the operation accuracy can reach several Millimeter, can achieve a needle under the water.
According to the British "Financial Times" reported in 2014, the British SMD company, the full name of the British Soil Machinery Power Co., Ltd., is the second largest provider of deep-sea robots in the world, with strong advantages in deep-sea robots, subsea engineering machinery manufacturing and other fields. Its submarine self-propelled trenching, cable laying engineering machinery field, which accounts for 75% of the global market for excavation equipment, is also the only company in the world that has produced and carried out deep sea mining. It used to use deep sea equipment at 1600 meters deep water. Mining gold.
In 2015, CSR Times Electric invested about 130 million pounds (about 1.2 billion yuan), acquired 100% of the company's shares, and officially entered the field of marine engineering equipment. According to the British "Financial Times" reported in 2014, it is expected 2014-18 The annual global deep-sea robot system will have a capital expenditure of $117 billion. However, due to the high technical threshold and large investment demand, there were few Chinese companies involved in the fast-growing deep-sea robot market. Therefore, CZ Zhuzhou decided to acquire the British SMD company.
Chen Jian, deputy general manager of CZ Zhuzhou, and chairman of SMD, told reporters that the future development direction of SMD will focus on deep sea operations, including oil and gas engineering, deep sea cabling, and offshore operations, including offshore wind power projects. Cable laying, etc.
In Chen Jian's view, the reason why the medium-sized car as a domestic rail transit giant has entered the marine field is because both sea and land products have a common feature, and they all belong to high-end equipment. The vision of the medium-sized car is dedicated to the manufacture of high-end equipment. '
Chen Jian said that at present, not only in China, but also in the global deep-sea equipment field, CRRC has become the leader. Among them, the trencher has a market share of more than 67% in the world and is in a leading position. On July 17th, The ROV deep sea robots in the world are ranked in the top three in the world.
