WinGD pushes alternative fuel race forward with ethanol engine debut

WinGD has officially pioneered the maritime energy transition by securing the world’s first orders for ethanol-fuelled engines, set to power two massive Guaibamax ore carriers. This milestone represents a significant shift for ocean-going vessels seeking viable low-emission alternatives to traditional heavy fuel oil. By integrating the innovative X-DF-M/E engine technology, the Swiss designer is actively reshaping the propulsion landscape, offering a cleaner pathway for bulk carriers operating on global trade routes and pushing the industry toward decarbonization goals.

The adoption of ethanol as a marine fuel necessitates strict adherence to the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code), which falls under SOLAS Chapter II-1. Compliance departments must ensure that these vessels meet the specific risk assessment criteria outlined in MARPOL Annex VI regarding nitrogen oxide and sulfur emissions. Furthermore, classification societies are currently updating their technical standards to govern the storage, bunkering, and combustion of ethanol, requiring shipowners to maintain rigorous documentation to satisfy both flag state requirements and port state control inspections.

This technological shift directly impacts chief engineers and second engineers, who must prepare for specialized training on ethanol-specific fuel handling and combustion management. These technical officers will need to master new fuel supply systems, safety protocols for low-flashpoint fuels, and updated maintenance procedures for the X-DF-M/E engine series. Understanding the chemical properties of ethanol and the associated fire suppression requirements will be essential for maintaining operational safety and ensuring regulatory compliance on these next-generation ore carriers.
