CMA CGM has trialled WinGD’s Variable Compression Ratio (VCR) technology onboard one of its vessels.
The partnership is the first field test for the new dual-fuel engine technology, after successful manufacturing testing that demonstrated considerable efficiency increases with diesel and LNG fuels.
VCR adjusts the cylinder compression ratio in X-DF dual-fuel engines according to fuel selection, ambient conditions, and engine load, lowering fuel consumption and GHG emissions.
The WinGD technology represents the first instance of using an adjustable compression ratio in a marine engine, which is typically a fixed design parameter.

The CMA CGM project comprises a long-term, full-scale test to confirm operability and reliability. Onboard testing is expected to begin following the dry-docking of the vessel in September when VCR will be installed on the vessel’s WinGD RT flex50DF dual-fuel engine.
WinGD Vice President R&D, Sebastian Hensel said: “Partnering with leading shipping companies is vital to prove the benefits of new technologies in real-life operating conditions. We applaud CMA CGM for their vision in promoting sustainable shipping and for recognising the potential for VCR to further these ambitions.”
In July, WinGD completed testing for its X52-S2.0 engine for medium-bore two-stroke engines.
