Swiss marine power firm WinGD has secured an order to supply Polaris Shipping with four X72DF-M-1.0 engines that can burn either methanol or ethanol, giving the owner fuel flexibility for its planned Newcastlemax vessels. The arrangement was reported on 10 September 2026.

The contract covers four dual-fuel engines of the X72DF-M-1.0 type, a model described by the supplier as capable of operation on both methanol and ethanol. Polaris Shipping will fit the engines to ships in its future Newcastlemax fleet, the report states.

The choice to specify engines able to run on two different alcohol fuels reflects an emphasis on operational flexibility rather than a single-fuel strategy. Polaris will be able to switch between methanol and ethanol as market conditions and fuel availability change.

Technical flexibility

Dual-fuel capability in this case means the same engine design can accept either methanol or ethanol as its primary fuel, without the owner being restricted to a single supply chain. That feature reduces the risk of fuel shortages or logistic constraints dictating vessel operations.

WinGD, identified in the report as a Swiss marine power company, supplied the X72DF-M-1.0 units in the order. The specification ties the propulsion choice directly to the fuel options Polaris intends to keep available across its new Newcastlemaxes.

Commercial and operational implications

For a Newcastlemax programme, the ability to accept two liquid alternative fuels can alter commercial planning, because charterers and operators increasingly factor fuel choice into routing and employment. Polaris’s specification suggests it is seeking to safeguard voyage flexibility amid shifting fuel markets.

Equipping newbuilds with engines certified to burn both methanol and ethanol will influence the owner’s procurement and bunkering arrangements. Owners with multi-fuel-capable systems can respond to regional differences in supply and to price signals without retrofitting.

Several strategic considerations follow from the contract. Having a fleet able to operate on more than one fuel provides an immediate operational buffer against regional shortages. It also allows shipowners to react to changing commercial incentives that favour one fuel over another.

The order also signals continued market demand for engines designed around alcohol fuels as owners plan new tonnage. By specifying dual-fuel methanol and ethanol capability, Polaris Shipping has prioritised adaptability in the propulsion choices for its forthcoming Newcastlemax vessels.

Observers will watch how the choice affects Polaris’s shipbuilding and procurement decisions, and how bunkering networks respond to vessels that can accept either methanol or ethanol. The WinGD contract is an early indicator of how some owners are approaching the practicalities of fuel transition on newbuild programmes.
