Piening Propeller will present its PCP (Piening Controllable Propeller) with water hydraulics at SMM 2026. Instead of conventional hydraulic oil, the system uses water as the hydraulic medium, eliminating the risk of oil pollution and supporting environmentally friendly vessel operation.
According to the company, the technology offers both environmental and economic benefits by replacing oil with water while reducing the costs associated with handling hydraulic fluids. The PCP with water hydraulics has already been supplied for a range of applications and is in operation on various vessel types.
One current reference project is a series of offshore patrol vessels (OPVs) under construction by Fassmer for the Mexican Navy. The vessels, designed for speeds of more than 30 knots, will be equipped with the PCP and water hydraulic system. For both companies, the project marks an important step in expanding the application of the technology to high-speed naval vessels.
The PCP is available in diameters ranging from 1.1 m to 5.4 m and for power ratings between 300 kW and 10,000 kW, depending on the vessel type and operational requirements. This allows the controllable pitch propeller system to be adapted to a wide variety of applications.
According to Piening Propeller, the PCP has been developed to meet increasingly stringent international environmental requirements while maintaining the performance and reliability expected from modern propulsion systems.
Visitors to the company’s stand will have the opportunity to learn more about the water hydraulic concept and its potential for commercial and naval applications.
