Dongyuan 01 wave-piercing catamaran
The “Dongyuan 01”, was the largest domestic all-aluminum wave-piercing catamaran in China. The wave-piercing catamaran is a new composite ship designed to absorb the advantages of high speed and low consumption of conventional catamaran and excellent wave resistance of small waterplane ships. It consists of two elongated main hulls, central hull and superstructure. composition. The length of the two elongated main hulls is very sharp, so the reserve buoyancy of the crotch is very small, and the special hull line type enables the ship to smoothly cut waves when the ship is sailing in the waves, so that the hull The roll, heave and pitch are much smaller than the conventional ship type.
Based on modern fluid mechanics theory, the high-performance ship adopts advanced overall ship design, propulsion, transmission, control methods and new technical materials. It is different from conventional drainage type and has high speed, high wave resistance and high cost-effectiveness. It is the most innovative and innovative ship type. The development of high-performance ships has gone through the hydrofoil in the 1940s, the hovercraft in the 1950s, the ground-effect wing in the 1960s, the high-speed catamaran in the 1970s, and the rapidly developing high-speed wave-piercing catamaran in the late 1980s.
Several stages of small waterplane catamaran. Its development depends not only on advanced ship type technology research, but also on light and high-power diesel engines, lightweight high-strength new materials such as aluminum alloy and its welding technology, efficient propulsion mode, flexible and reliable motion control system, and perfect supporting Equipment and equipment are a comprehensive reflection of the state's scientific and technological level and advanced manufacturing capabilities. Most of the high-performance ships used in China are imported from abroad.
Built by CSIC Zhongyiyi and Wuchang Shipbuilding Heavy Industry Co., Ltd., Dongyuan 01 was started in September 2007 and was delivered in December 2009. . The successful design and construction of the ship further promoted the rapid development of high-performance ships in China. The “Dongyuan 01” wave-piercing catamaran is an all-aluminum high-end ship with independent intellectual property rights designed and independently developed and built by CSIC. The total length of the ship is 60 meters, the width is 18 meters, and the middle span is 11 meters. With a depth of 5.9 meters and a maximum speed of 38 knots, it is a deep V linear wave-piercing catamaran with a pump-jet propulsion system. It is a non-propeller high-performance ship that can achieve 360-degree rotation in situ. The ship adopts advanced materials, advanced line type, advanced equipment and advanced manufacturing technology. It is a high-tech ship with international level, advanced, stable, rapid and comfortable. In mid-December 2009, after passing the sea trial test, the ship has excellent performance and fully meets the design specifications.
Chinese wave piercing ship Beidiao 990 is the largest Chinese developed ship with wave-piercing hull. Designed by the 701st Institute of China Shipbuilding Industry Corporation (CSIC), the ship was built by Wuchang Shipbuilding Industry Company Ltd., and was launched on June 1, 2009. Beidiao 990 has a deep-V shaped hull, and the entire ship is constructed of aluminum, the first of its kind in China. The high grade aluminum needed for the construction of the ship is supplied by Beijing Alumip Development Co., Ltd. The name Beidiao 990 means North (Sea Fleet) Investigation (Ship) 990, and the ship is unique in that it also has a second name Dongyuan 01, meaning East Distant. Although capable being deployed as a platform for various missions such as surveillance, survey, and research, the ship is currently used as a troopship by the People's Liberation Army Navy (as of 2014) to rotate sailors and marines.
China's wave-piercing catamaran design technology started in 1997. With the support of the National Economic Mobilization Office, Beijing CSSC Dongyuan Technology Development Co., Ltd. organized the relevant institutions to use the basis of digestion and absorption of foreign ship design technology for nearly five years. In the past, through performance research and experiments, it mastered the key technologies of the design of the wave-piercing catamaran.
Due to the need for operating conditions, the "Dongyuan 01" test ship propulsion system selected 4 TBD620V16 high-speed diesel engine as the propulsion host, through the high-elastic coupling, gearbox, transmission shaft drive 4 imported MJP750 mixed-flow water pump propulsion, 4 sets of propulsion devices independent of each other, the total power of about 8,000 kW, The inlet is made of glass and steel. The system has the advantages of high power, high speed, flexible mobility and so on, and at the same time set the direction stability system at the tail, which makes the ship have good stability in the course of high-speed navigation.

In December 2005, the yard independently developed and successfully delivered the first catamaran of this type in China.
