Ship thrusters are equipment in ship propulsion devices that convert the power generated by the engine into mechanical energy to propel the ship forward. The full rotary thruster is a kind of ship thruster, which has the functions of propulsion and control direction at the same time, and is the key core component of the ship's dynamic positioning system, which can arbitrarily change the thrust direction, make the ship turn around in place, and greatly improve the maneuverability of the ship.
According to the "2021-2025 Full Rotary Thruster Industry In-depth Market Research and Investment Strategy Recommendation Report" released by the New Thinking Industry Research Center, with the continuous improvement of ship maneuverability requirements, the application penetration rate of full rotary thrusters in ships has continued to increase. In addition to ships, full slewing thrusters can also be used in offshore platform propulsion devices. The downstream application areas of the full rotary thruster are mainly small and medium-sized offshore engineering platforms and ships. In 2020, the global full slewing thruster market size is about 3.65 billion yuan.
The work of the full rotary thruster is achieved by rotating the propeller 360° around the vertical shaft by the action of the bevel gear device and the worm gear device. Because the full rotary thruster mainly works in the ocean, facing a complex working environment such as wind and waves, it will have a great impact on its propulsion and control, in order to ensure its operational reliability, direction control, service life and other properties, its product structure is more complex, and the requirements are higher in raw material selection, technology and other aspects.
According to the power division, the full rotary thruster mainly includes less than 1500 kilowatts, 1500-3500 kilowatts, greater than 3500 kilowatts and other major categories of products, the greater the power, the higher the manufacturing technical requirements. Globally, the main manufacturers of full slewing thrusters are Schottel of Germany, Vuitth Turbo of Germany, Rolls-Royce of The United Kingdom, Berg Propulsion of Sweden, Brunvoll of Norway, Wärtsilä of Finland, Steelprop of Finland, ABB of Switzerland, Veth Propulsion of the Netherlands, Trystmaster of the United States, IHI of Japan, Kawasaki of Japan, etc. Among them, Schottel is the world's largest producer of full-rotation thrusters.
China's ship thruster industry technology continues to advance, but there is still a certain gap compared with the international leading enterprises in terms of advanced technology. In the "14th Five-Year Plan" national key research and development plan "high-performance manufacturing technology and major equipment" released by China, it is proposed to study the design and manufacture of key technologies and equipment for the design and manufacture of high-thrust full-rotation thrust thrusters for ships in the deep sea. Under the impetus of national policies, China will independently develop and produce large-thrust full slewing thrust thrusters, which is conducive to improving the core competitiveness of the full slewing thruster industry.
New thinking industry analysts said that the ship thruster is the key component of the ship's power system, the full rotation thruster has the two major functions of propulsion and direction control at the same time, which can greatly improve the mobility of the ship, and its research and production are of outstanding importance. China is a global shipbuilding power, but there are still technical bottlenecks in the research and development and design of core components, which has become an important problem restricting the development of China's shipbuilding industry. China's policy is encouraging the study of key technologies for high-thrust full-swing thrust thrusters, and it is expected to achieve independent production in the future.
