New Streamline-CRP contra-rotating propulsion system is designed to improve efficiency, reduce emissions and enhance passenger comfort on inland waterways
Veth Propulsion, part of Twin Disc and a global leader in marine propulsion and manoeuvring solutions, has unveiled the Streamline-CRP™ at the Maritime Industry, one of the Netherlands’ leading inland shipping trade exhibitions, where it attracted attention for its focus on efficiency, sustainability and passenger comfort.
The new product, Streamline‑CRP™, is a major step forward in contra‑rotating propulsion technology. It was developed to meet the demand for higher efficiency, reduced emissions and better onboard comfort. It is purpose‑built for passenger cruise vessels and ferries. Streamline‑CRP delivers superior hydrodynamic performance, even in demanding, shallow‑water conditions.
Streamline‑CRP is a next-generation azimuth thruster. It builds on Veth Propulsion’s long experience designing and making advanced propulsion systems.
“Customers across the marine industry are demanding solutions that deliver both performance and efficiency,” said Bastiaan van Zuijlekom, Managing Director of Veth Propulsion. “Streamline‑CRP responds directly to those needs by combining proven contra‑rotating propeller (CRP) technology of precise vessel control and optimal thrust in all directions along with reducing fuel consumption, minimizing noise and vibration, providing a smoother, more efficient operating experience.”
Streamline‑CRP is a fully integrated propulsion solution. It combines performance‑enhancing features into one optimized system. Its redesigned gearbox uses combined push‑pull technology to optimize flow and reduce resistance. The long, slender tail section reduces drag and improves hydrodynamic efficiency. Proven CRP technology gives balanced thrust for reliable propulsion. Optimized propeller hub caps also help reduce energy losses.
The new system is available in multiple configurations, including L‑Drive, Z‑Drive and compact integrated thruster solutions. This flexibility enables seamless integration across a wide range of vessel designs. The system offers a standard 4/5-blade setup with 5/6 or 6/7-blade options for application tuning. An integrated flange cover increases protection and creates a cleaner, lower-drag interface. These features refine flow, reduce noise and improve onboard comfort.
With its refined design, Streamline-CRP cuts fuel consumption by up to 7% in real-world use. This improvement lets operators run more efficiently and meet sustainability goals.
“Veth Propulsion remains committed to delivering innovative propulsion technologies that improve performance while reducing operational impact,” added van Zuijlekom. “Streamline‑CRP sets a new benchmark for quiet, efficient marine propulsion and represents the next step forward for our customers and the industry.”
