WinGD milestone: Natgas-VOC fuel mix for X-DF engine 'successfully tested'

Development means VOC waste product can now be utilized as fuel.

Winterthur Gas & Diesel Ltd. (WinGD) reports that, together with Wartsila Gas Systems, it has "successfully tested" a natural gas with volatile organic compounds (NG-VOC) fuel mix for the WinGD X-DF engine, selected to power two 125,000-deadweight-tonne (dwt) shuttle tankers for AET.

The development is described by WinGD as having "considerable implications for both the oil and gas industry and the environment".

Whereas historically, VOCs - a waste product from crude oil handling and transport - have been both a hazard and a loss of revenue to oil and gas producers and shippers and have been either discharged into the atmosphere or burned off, with the development of the X-DF engine's new fuelling mode, VOC can now be turned into a viable source of energy.

Representatives from AET, Statoil, OSM Maritime Group, Samsung Shipyard and Hyundai Heavy Industries-Engine & Machinery Division were on hand in Trieste, Italy, in March, to witness the test of a WinGD X-DF engine running on an NG-VOC mix.

The test assessed the engine's capabilities under various load scenarios with up to 20 percent VOC in the fuel ratio.

"The engine sustained high performance throughout transfers from pure NG to a VOC mix, as well as transferring to diesel mode and back again. Notably, while maintaining efficiency, NOx emissions remained significantly below IMO Tier III levels while operating on the NG-VOC mix," WinGD said.

WinGD also emphasized that, in order to burn the NG-VOC mix, the X-DF engine concept remains unchanged.

"There are no significant changes in performance and emissions behaviour - the engines are fully IMO Tier III compliant burning the natural gas-VOC mix. In fact, aside from a few precautions according to ambient and boundary conditions, no hardware modifications and no application-specific control functions are required on the engine, and standard tuning can be retained. Likewise, the gas handling safety philosophy is identical with X-DF dual-fuel engines burning natural gas solely," explained Marcel Ott, Senior Project Manager DF Technology, Research & Development at WinGD.

It was also established during the project that, in contrast to a high-pressure system, the low-pressure gas admission feature of the X-DF engines is beneficial for mixing VOC into the natural gas fuel, since condensation of the heavy hydrocarbons in the VOC can be avoided.

Discussing the evolution of the project, Ott said: "An early finding on the first X-DF engines with low-pressure gas admission to enter service was that their inherently stable combustion gave scope to run the engines on gas with lower methane numbers. Working with our partners from Wartsila Gas Systems from Norway and the local team at the Wartsila test facility in Trieste, we have applied this knowledge to the new fuel combination."

WinGD's Vice President R&D, Dominik Schneiter, noted: "We understand the pressures faced by today's shipping industry and simple solutions are key. Our X-DF engines now offer ship owners a further way to improve their environmental footprint while at the same time reducing fuel cost - and without increasing the basic simplicity of our X-DF engines with low pressure gas admission. The NG-VOC capability will add a further dimension to the benefits that make our X-DF engines such a strong contender for ship owners facing tighter emissions controls and increased operating costs."
