Swiss marine power company WinGD has secured a contract to supply four X72DF-M-1.0 engines for Polaris Shipping's future Newcastlemax fleet, giving the vessels the ability to run on either methanol or ethanol. The dual-alcohol capability is designed to give the South Korean bulk carrier operator flexibility to adapt to shifting fuel availability, pricing and regulatory requirements throughout the ships' operating lives. Dr. Carmelo Cartalemi, Head of Strategic Marketing at WinGD, said shipowners are seeking flexible solutions to meet decarbonisation targets without compromising reliability, safety or financial stability, noting that the alcohol-fuel engine platform lets owners choose whichever fuel best suits operational and commercial needs as markets evolve. Polaris Shipping said the engine choice avoids having to predict today which fuel will be most competitive in future, giving it confidence to invest for the long term. WinGD will also provide dedicated service and lifecycle support to help the company build familiarity with the technology and adopt methanol and ethanol propulsion safely. The order adds to WinGD's expanding orderbook of alternative-fuel engines, which now covers LNG, methanol, ethanol and ammonia. The company is separately working with Beihai Shipyard on installing its ammonia-fuelled engine for CMB TECH's newbuild 210,000 dwt dry bulk carriers. WinGD said its alternative-fuel technology is increasingly moving from development and testing into vessel construction and operation, supporting shipowners' decarbonisation strategies while preserving fuel-choice flexibility.
