⚙️ Retrofit for the Future: Fuel Conversions with WinGD Ltd.
Decarbonising existing vessels doesn’t mean starting from scratch.
WinGD retrofit solutions allow shipowners to convert today’s X-Engines to tomorrow’s fuels including LNG, methanol/ethanol, ammonia and LPG.
Thanks to a robust common engine platform, both single-fuel and dual-fuel X-Engines can be upgraded with proven retrofit packages, backed by first-hand project experience.
⬇️ Lower emissions
✅ Improved EEXI & CII
🌍 A practical pathway to net zero

🗣️ Let’s Talk LNG!
❓What are low-pressure and high-pressure dual-fuel LNG engines?
Dual-fuel LNG engines are designed around two different combustion concepts: the Diesel cycle and the Otto cycle. The key distinction lies in how LNG is introduced into the cylinder and how combustion is initiated.
🔧Diesel Cycle (High-Pressure Injection)
High-pressure dual-fuel engines follow the same combustion principle as conventional low-speed diesel engines. LNG is injected directly into the combustion chamber at very high pressure, alongside a small amount of pilot fuel. The pilot fuel ignites the gas, enabling robust combustion and high efficiency across a wide operating range.
⚙️ Otto Cycle (Low-Pressure Admission)
Low-pressure dual-fuel engines operate on a lean-burn Otto cycle. In this concept, LNG is admitted to the combustion chamber at low pressure before piston compression begins. Combustion is then initiated by a high-pressure injection of pilot fuel, resulting in lower combustion temperatures and reduced emissions.
WinGD Ltd. now offers both concepts within its LNG dual-fuel portfolio.
By offering both low-pressure and high-pressure LNG solutions, WinGD provides ship operators with flexibility to select the engine concept that best aligns with their operational profile, fuel strategy, and emissions targets.

⚡🚢WinGD Ltd. X-S-Series: Compact Power for a New Generation of Ships
The WinGD X-S-Series of short-stroke engines combines state-of-the-art efficiency, optimised lifecycle cost, and fuel flexibility in a compact package.
The X-S-Series comprises two diesel and two dual-fuel engines with reduced height, weight, and footprint compared with the standard X52 and X62 platforms. Designed for vessels with restricted engine-room space, the X-S-Series replaces the trusted RT-flex50 and RT-flex58 while setting a new benchmark for compact performance.
Key advantages:
🧩 Compact design
⚙️ Best-in-class fuel efficiency
🔋 Fuel-flexible engines – ready for LNG, methanol/ethanol, and ammonia
The WinGD X-S-Series: smaller footprint, greater performance

⚙️ Variable Compression Ratio: A Practical Retrofit Route to IMO 2030
WinGD Ltd.’s latest white paper ‘LNG-Fuelled Fleets Reducing Emissions: VCR retrofitting as a ready solution’, sets out how LNG-fuelled vessels can achieve near-term emissions reductions through Variable Compression Ratio (VCR) retrofitting.
🗣️ In an article, Rene Baart, Head of Retrofit Solutions at WinGD, introduces the paper and explains why retrofitting in-service ships will be central to meeting IMO 2030 targets. He outlines how VCR technology improves fuel efficiency and reduces methane slip across real-world operating profiles.
With no added operational complexity and no change to fuel strategy, VCR represents a proven, ready solution for owners seeking practical progress towards compliance.

🗣️ Let’s talk Methanol!
How did WinGD validate the X-DF-M concept?
Through a rigorous data validation process combining real engine tests, combustion chamber experiments, and advanced simulations.
⚙️ Real Engine – Extensive measurement series used for calibration and validation.
🌬️Spray Combustion Chamber – Enables accurate CFD modelling of the combustion process.
✅0D/1D GT-Power Model – Calibrated to match real engine data.
🔍Simulation vs Experiment – Ensures that methanol combustion models are fully validated in a real engine environment.
With this approach, methanol engines, built on proven diesel base hardware but adapted for unique combustion properties, are supported by robust, validated models. This ensures reliability, safety, and performance as methanol becomes a key pathway to maritime decarbonisation.
X-DF-M engines are also readily adaptable for ethanol, leveraging the same combustion understanding, modelling tools and validation methodology.

🛠️ Built for Today, Ready for Tomorrow: The X72DF2.2 for LNG Carriers
As the maritime industry advances toward decarbonisation, LNG continues to stand out as the most practical solution for ship operators to cut greenhouse gas (GHG) intensity today, while providing a direct pathway to deeper decarbonisation through bio- and synthetic methane.
Since 2018, WinGD Ltd.’s X72DF has been the engine of choice for LNG carrier newbuilds, setting the industry benchmark for efficiency and reliability. Building on this legacy, the X72DF2.2, introduced in 2021, was developed specifically to meet the evolving needs of LNG carrier operators - reducing footprint, weight, and cost while delivering even greater value to both shipyards and owners.
With low CAPEX and OPEX, reduced total GHG emissions, and a future-ready route to compliance as carbon costs rise, WinGD’s X-DF technology continues to evolve the standard for LNG propulsion.
