BERG propulsion contributes to substantial efficiency gains for CMA CGM

The collaboration between BERG Propulsion, CMA CGM, and ship owner Reederei Rambow has resulted in significant efficiency improvements for the 868 TEU container vessel, Henneke Rambow. Originally built in 2007, the ship has been transformed into one of the top performers in its class through a comprehensive retrofit project. Initiated by charterer CMA CGM, the project involved BERG Propulsion working closely with Rambow to optimize the vessel’s performance in line with current and future operational needs.

The upgrade, approved by DNV, focused on optimizing the vessel’s propulsion system for enhanced fuel economy, particularly as the Henneke Rambow operates at speeds lower than its original design. Key modifications included the replacement of the existing propeller blades with hydrodynamically optimized profiles and the integration of BERG’s advanced MPC800 propulsion unit with Dynamic Drive. Additionally, a custom-made Network Frequency Stabilizer was installed, allowing the shaft generator to operate at variable speeds while maintaining a stable frequency and voltage.

Following the completion of the retrofit, Reederei Rambow reported a significant improvement in the ship’s operational efficiency, ensuring its competitiveness for years to come. The project underscores the importance of collaboration between owners, charterers, and systems integrators in optimizing ship performance, especially as the shipping industry transitions towards greater efficiency and decarbonization. BERG Propulsion’s approach highlights the potential for older vessels to remain competitive in the evolving landscape of global shipping.
