WinGD is set to trial its innovative Variable Compression Ratio (VCR) technology aboard a CMA CGM vessel, marking the first field test of this groundbreaking dual-fuel engine technology.
This collaboration follows successful factory tests that demonstrated significant efficiency gains with both diesel and LNG fuels, promising a major step forward in sustainable shipping.
“This partnership with CMA CGM is crucial for demonstrating the real-world benefits of VCR technology,” said Sebastian Hensel, WinGD vice president R&D.
“We commend CMA CGM for their commitment to sustainable shipping and their foresight in recognising the potential of VCR to advance these goals.”
Adjustable compression
WinGD’s VCR technology dynamically adjusts the cylinder compression ratio in X-DF dual-fuel engines based on fuel type, ambient conditions and engine load.
This adaptability reduces fuel consumption and greenhouse gas emissions, making it the first marine engine to use an adjustable compression ratio - a parameter traditionally fixed in engine design.
The full-scale test will begin after the vessel undergoes dry-docking in September, during which the VCR system will be installed on the WinGD RT-flex50DF dual-fuel engine.
This trial is part of CMA CGM’s broader initiative to achieve net zero carbon by 2050, applying sustainable solutions across its fleet.
The VCR technology’s potential to improve fuel efficiency, reduce methane slip and enhance operational flexibility supports ship owners and operators in their journey towards decarbonisation.
WinGD envisions this technology playing a key role in the transition from fossil fuels to synthetic or biomass-derived LNG.
