WINGD OFFERS A HOLISTIC APPROACH TO MARINE DECARBONISATION

WINGD OFFERS A HOLISTIC APPROACH TO MARINE DECARBONISATION

Tuesday, September 21, 2021 

Engine developer WinGD has introduced what it calls an 'ecosystem of solutions' around the main engine in order to enhance energy efficiency and enable a seamless transition to new fuels the two keys to reducing greenhouse gas (GHG) emissions in line with IMO ambitions.

The WinGD solutions deploy digital vessel optimisation and battery-hybrid energy systems to improve the energy efficiency and future fuel flexibility of its two-stroke engines. Using LNG as fuel in a low-pressure X-DF engine, for instance, can reduce GHG emissions by around 20% compared to a conventional two-stroke engine burning HFO. Combined with the new solutions, CO2 equivalent emissions can be reduced further - taking vessels beyond IMO’s intermediate target of reducing carbon intensity by 40% by 2030.

CEO Klaus Heim said: “Our ecosystem approach to energy efficiency acknowledges that vessels today are complex power systems with the main engine at the heart of the integrated solution. These systems, including our engines, are fully ready for the future fuels that will take ships much further than IMO’s target of cutting greenhouse gas emissions by at least 50% by 2050.”

The solutions include fuel flexibility and smart engine monitoring combined with advanced electronic control and hybrid energy management systems. WinGD’s engine experience means that it can integrate all elements of these complex systems optimally, including advising ship owners on the sizing and operation of hybrid energy sources such as batteries.

In a recent landmark project, WinGD is integrating sustainability and efficiency enhancements through a hybrid energy system onboard four pure car and truck carriers ordered by Japanese owner NYK Line. The vessels will run on LNG, using WinGD’s 7X62DF-2.1 two-stroke engines coupled with shaft generators, DC links and battery systems. WinGD has optimised spinning reserves, peak shaving, and energy flow to run the main engine at its sweet spot as much as possible while reducing the use of less efficient auxiliary engines. The system will be managed by WinGD’s new Hybrid Control System.

“Such integrated energy management plays a key role in our vision to power the energy transition in shipping.” said Heim. "Through WinGD’s progressive investments in future fuels, engine control, optimisation and hybridisation, combined with the continued evolution of our core engine technology, these advances give ship owners certainty that they can meet long-range environmental targets with systems they can order today.”

Underlying the new offering is WinGD’s Integrated Digital Expert (WiDE), a cutting-edge engine monitoring and optimisation solution that is standard on all medium and large bore WinGD engines. The monitoring and support capabilities work with the WinGD Integrated Control Electronics (WiCE) control system, that meets the connectivity and security demands of future ship energy systems. Combined with WinGD training for operators and a global service network, customers will be equipped to meet the challenges that lie ahead.

While developing the wider ecosystem of solutions, WinGD has continued to focus on the performance and sustainability of vessels powered by its engines. The emissions advantages of the dual-fuelled X-DF two-stroke series have been enhanced through the introduction of intelligent Cooling and Exhaust Recirculation (iCER), which cuts methane slip by around 50% as well as improving fuel consumption in both gas and diesel modes.

The X-DF engine can already run on carbon-neutral fuels including biogas or synthetic LNG without engine modifications, preparing ship owners for the next stage in their transition to lower carbon operations.

The benefits of future fuel flexibility and potential hybridisation are not limited to gas-fuelled engines. WinGD’s X engines are powered by liquid fuels, of which there are several emerging carbon-neutral or zero-carbon candidates, including bio-diesel and alcohol fuels. The company has invested in preparing to use these fuels, including leading European research into injection concepts. The core engine offering is continuously being developed to improve efficiency and flexibility, most recently with the addition of an integrated, on-engine NOx abatement solution for the marine two-stroke engine market.
