Swiss marine power company WinGD has signed a frame agreement with Panasia to upgrade X‑DF dual-fuel LNG engines in service with the latest emissions-abatement and fuel-efficiency technologies from WinGD, according to an official release.
The frame agreement, signed during Kormarine 2025, will support ship operators in reducing their cost exposure to maritime carbon pricing, keeping existing vessels competitive for longer.
Emissions upgrades for X-DF dual-fuel LNG engines
Panasia is a well-established marine technology developer and already acts as a system integrator for several shipyards. Its technical capabilities and understanding of specific vessel configurations will support WinGD in delivering timely and cost-effective retrofit projects that offer the best possible return on investment through lower fuel consumption and reduced emissions penalties.
WinGD brings unique product expertise to its retrofit projects, as the original designer of an engine platform that is under continuous development. Using its strong supplier and project partner network, WinGD provides a one-stop-shop for fuel conversions and energy efficiency upgrades, helping engine users to improve efficiency, reduce emissions and optimise operational costs.
The partnership will initially focus on solutions that allow X‑DF engines already installed on vessels to deliver the same fuel consumption, emissions and low methane slip as WinGD’s latest newbuild engines. Retrofit options include intelligent control by exhaust recycling (iCER) and variable compression ratio (VCR) technology, effectively converting X-DF engines to X-DF2.0 engines.
While iCER uses exhaust recycling to improve combustion stability when using LNG, VCR technology increases fuel efficiency by automatically optimising compression ratio depending on the fuel used and engine load. When combined, iCER and VCR technologies can reduce methane slip to around 0.7% of fuel gas volume—a more than twofold reduction compared to first-generation X‑DF engines. Alongside significant fuel consumption reductions, improved methane slip dramatically reduces the cost of compliance with European and proposed IMO regulations.
WinGD and Panasia are already engaged in retrofit discussions with multiple ship owners. As previously reported, WinGD has already completed the first retrofit of its VCR technology on a vessel operated by CMA CGM, with strong initial results presented at CIMAC World Congress in June.
