Winterthur Gas & Diesel (WinGD) has secured an order for the supply of the latest generation of X72DF-2.1 engines for 25 QatarEnergy vessels.

These vessels are part of QatarEnergy’s North Field East (NFE) project, which is claimed to be the largest ever liquefied natural gas (LNG) carrier newbuilding project.

Featuring WinGD’s new on-engine intelligent control by exhaust recycling (iCER), the 50 low-pressure dual-fuel engines were chosen by various shipyards and shipowners.

The company’s new on-engine configuration of iCER was launched in May. It enhances fuel efficiency in gas and diesel modes and also attains a 50% reduction in methane slip compared to the first-generation X-DF engine.

As part of the Qatar NFE programme, two 174,000m³ LNG carriers will use the new engines.

These vessels are being constructed for TMS Cardiff Gas at Korean shipyard Daewoo Shipbuilding & Marine Engineering (DSME ), where they will be the first ships built to incorporate the on-engine iCER systems. 

WinGD global sales director Volkmar Galke said: “This huge order intake with on-engine iCER technology shows the need for proven and reliable dual-fuel engines as the LNG carrier ordering surge continues.

“Owners and operators are seeking fuel flexibility without compromising efficiency, emissions or CAPEX. And the fact that all have chosen our latest compact, cost-saving configuration confirms that WinGD delivers the best possible solution to customers, giving them confidence in their investment for today and for the future.”

Several shipowners have tendered to construct gas carriers that will run under long-term charters to QatarEnergy. The vessels are expected to be delivered between 2023 and 2027.

WinGD engines are in service with 224 LNG carriers, and the company currently has more than 130 engines on order.
