Direct Drive Electric propulsion removes the gearbox from the equation, replacing it with a large permanent-magnet (PM) motor that connects straight to the propeller shaft.
This gearless configuration cuts mechanical losses, boosts efficiency, and keeps operations quieter and smoother. The result is a compact propulsion unit that simplifies installation and improves comfort while supporting full-electric and hybrid architectures.
At the core of the CPP system is a mechanism that alters the propeller blades pitch, which determines how far the propeller moves through the water with each revolution. By adjusting the propeller pitch, CPPs control the hydrodynamic angle of attack and propeller efficiency. Ensuring responsive handling whether accelerating, reversing, or performing precise low-speed maneuvers. Additionally, CPPs can provide lower thrust during maneuvers compared to fixed pitch propellers (FPPs), which are limited by minimum engine RPM, further enhancing maneuverability. These capabilities make CPPs a preferred choice for a wide range of vessel types operating in dynamic maritime environments.
Berg Propulsion’s CPP systems take this proven technology even further. With robust engineering, built in condition monitoring, and exceptional adaptability, our systems are built to deliver optimal propulsion performance and reliability — even under the most demanding conditions.

At the heart of the Direct Drive Electric system lies a high-torque permanent-magnet motor directly coupled to the propeller shaft. Without a gearbox, torque is transmitted directly and efficiently, minimizing frictional losses. The electric motor’s variable-speed control enables optimal performance in every operating condition, from harbor maneuvering to open-sea cruising, while maintaining smooth, vibration-free thrust delivery.
The Direct Drive Electric system can be deployed as part of:
It interfaces seamlessly with standard marine control systems and supports dynamic positioning, energy-management systems, and smart-monitoring platforms, ensuring compliance with IMO and EU efficiency standards.
With no gearbox and fewer moving parts, maintenance requirements are drastically reduced. Routine checks are simplified, and digital monitoring systems provide real-time insights into motor health and performance. Berg Propulsion’s global service network ensures responsive technical support, spare-part availability, and lifecycle optimization.
Direct Drive Electric propulsion supports the maritime industry’s transition toward zero-emission operations.
By enabling hybrid and fully electric configurations, it helps operators align with IMO 2030/2050 decarbonization targets and comply with EU Fit-for-55 requirements.
Its high efficiency directly lowers CO₂ and NOₓ emissions, reducing both environmental impact and fuel consumption.
As European sustainability measures intensify, the system also supports compliance with:
Together, these factors position Direct Drive Electric propulsion as a future-proof investment that reduces both operational costs and regulatory exposure while improving vessel performance.
The Direct Drive Electric has been successfully implemented on cargo and luxury vessels across Europe, delivering proven performance gains in efficiency, comfort, and sustainability.
