In March this year, the Ministry of Industry and Information Technology and the National Development and Reform Commission and other five departments jointly issued the "Middle- and Long-Term Development Plan for Marine Engineering Equipment Manufacturing Industry". According to the plan, by 2015, the annual sales revenue of China's marine engineering equipment manufacturing industry will reach more than 200 billion yuan, and the international market share of offshore oil and gas development equipment will reach 20%.
On April 11, in the CNOOC Bohai Company, a yellow robot spit out a laser beam from time to time, and “buried the head†to repair the pump shaft. Huagong Laser related person introduced that it is the first robotic semiconductor laser mobile repair equipment in China, and has just realized “sea and land useâ€: it has been successfully used for offshore drilling platform maintenance.
This robot occupies an area of ​​about 1 square meter, its own weight is 500 kilograms, and the "arm" has an elongation radius of 2.5 meters. It can grab more than 30 kilograms of laser generator and can twist 360 degrees in all directions, and dexterously melts metal powder into " Patch", repair restore device.
Compared to the “brothers†of many laser devices, it is not a big man – the staff can easily move it to the rig and repair it on site.
It is understood that the offshore working environment is special and the equipment is prone to decay and wear. Once the equipment is damaged, either the parts are put ashore, and it is not easy to disassemble and move the parts. Even if they can be removed, it usually takes half a month to go back and forth; or, the site uses electric welding, but the welding temperature is too high, and it is easy to burn the precision equipment. .
The laser maintenance system is monopolized by foreign companies and the price is high. The robot of Huagong Laser is the first in China, and its price is 20%-40% lower than that of similar foreign products.
Another product of Huagong Technology, the Trident CNC plasma cutting machine, is equipped with a high-end marine crane.
This plasma cutting device can cut 12 meters of steel plate in one minute. It is 10 times of traditional flame cutting and has a thickness of 130 mm. The most important thing is that its positioning accuracy is 0.25 mm, which is almost the width of 4 hairs. World class level.
Underwater cutting is also one of its unique features: it can effectively eliminate noise, dust, harmful gases and arcs caused by cutting.
The “Offshore Oil 201†jointly built by Rongsheng Heavy Industry and CNOOC is the first offshore engineering ship in Asia with 3000 meters deep water operation capability. It can operate in the global infinity area outside the Arctic, and its hull steel plate is cut with this equipment. . Previously, domestic mainstream shipbuilding companies used German and Japanese enterprise products.
The relevant person in charge of the Wuhan Economic and Information Committee said that some equipment manufacturing enterprises in Wuhan, such as Wuchuan, Wuqiao Heavy Industry, Wuhan Shipbuilding, Huagong Technology, etc., have achieved breakthroughs in the high-end offshore market through independent research and development. Great development space.
The industry conservatively estimates that in 2011-2015, the annual average capacity of the world marine engineering equipment market will be more than 70 billion US dollars. In the next 5 years, the total investment in marine engineering equipment will be at least 350 billion US dollars.
At present, the annual sales revenue of China's offshore engineering equipment is less than 40 billion yuan, accounting for only about 10% of the global market. Last year, China’s 3,000-meter deep-water semi-submersible drilling platform “Offshore Oil 981†cost as much as 6 billion yuan, of which nearly 4 billion yuan was imported from abroad.
