Controllable pitch propeller propulsion system

The company has independently developed a full range of WP-type controllable pitch propellers (CPPs), suitable for a wide range of vessel types, including naval vessels, offshore engineering vessels, multipurpose vessels, dredgers, maritime surveillance and fishery law enforcement vessels, and fireboats. Designed based on a standardized, modular, and serialized approach, these products are comparable to advanced international technologies, achieving performance levels comparable to those of comparable international standards and maintaining a leading position in China. The company possesses an integrated design and development platform for the main propulsion system, capable of designing and supporting everything from the main engine, high-elevation propellers, gearboxes, controllable pitch propellers, shafting, and remote control systems. Compared to comparable domestic products, the WP-type CPPs offer advantages such as a high power-to-weight ratio, strong load-bearing capacity, and superior propulsion efficiency.
