A collaboration between BERG Propulsion, shipping and logistics group CMA CGM and ship owner Reederei Rambow has proved pivotal in significant efficiency gains for an 868 TEU container vessel, with the 2007-built ship rejuvenated as one of the top performers in its class.
In an innovative retrofit project requested by charterer CMA CGM, BERG worked with Rambow on a comprehensive package of efficiency optimization measures onboard Henneke Rambow to match current and anticipated requirements. Recommendations followed a performance review by BERG, analysis of the vessel’s installed propeller and data-based scrutiny of its propulsion system.
With Henneke Rambow consistently operating at speeds lower than its original service speed, the DNV class-approved upgrade focused on optimizing the propulsion solution for fuel economy. The owner’s retrofit project also included optimization of the ship’s bulbous bow for a revised operational matrix.
In addition, BERG installed its custom-made Network Frequency Stabiliser (NFS), which allows the shaft generator to operate at variable speeds while continuously providing a stable frequency and voltage to the main switchboard.
Upon completion, owner Reederei Rambow reported significant gains in Henneke Rambow’s operational efficiency.
BERG has undertaken a series of retrofits focusing to optimize older ships to ensure that they remain competitive in the era of carbon intensity monitoring and emissions trading.
