WinGD X-DF engines to drive gas-powered Aframax tanker
The X62DF dual-fuel engines will power four ice-class 1A, 114,000 dwt Aframax tankers

Winterthur Gas & Diesel (WinGD) has announced that its low-speed dual-fuel engines with X-DF low-pressure gas admission will propel the first ever gas-fuelled Aframax crude oil tankers.

Sovcomflot (SCF Group), Russia’s largest shipping company, has chosen seven-cylinder, 62cm bore type 7X62DF engines from WinGD’s X-generation to propel a series of four LNG-fuelled Aframax-class tankers. The ships will be built by Hyundai Heavy Industries (HHI) of South Korea at its shipyard in Samho, while the 7X62DF engines will be built by HHI’s Engine & Machinery Division (HHI-EMD) in Ulsan, South Korea.

The 7X62DF engines are rated 13,800 kW at 86 rpm and designed to operate on a choice of LNG, HFO, distillate or hybrid liquid fuels. The engines comply with IMO Tier III limits for oxides of nitrogen (NOx) in their gas fuel mode, and with IMO Tier II when burning liquid fuel. To enable IMO Tier III compliance on liquid fuel operating mode, the contract also specifies the supply of low-pressure selective catalytic reduction after-treatment systems for the 7X62DF engine.

As well as the engine designs, WinGD will also supply its engine diagnostic system, which targets increased availability via monitoring, lower fuel costs via engine performance, optimising and extension of predicted times between overhaul of components.
