Low speed engine company WinGD says that a South-Korea based shipping company is planning newbuilding orders for two 180,000 dwt gas-powered Capesize bulk carriers featuring its latest technology for improved efficiency and reduced emissions.

The company says that the choice of its X-DF2.0 engines with iCER technology is evidence of a commitment to sustainability and an investment in the future. The LNG-fuelled newbuilds will be equipped with 6X72DF 2.1. engines, the first of this engine size to use the Intelligent Control through Exhaust Recycling (iCER) technology. This technology upgrade will offer the ship owner improved engine performance with both LNG and any future carbon-neutral fuels they choose as they become available. 

iCER is said to be a simple and reliable technology using components which have been used for decades in the marine industry and builds on the proven X-DF engine technology. The low-pressure recirculation concept deployed on X-DF2.0 engines has been tested over recent years and specifically adapted to the successful X-DF Otto cycle engine technology. It claims several design and performance advantages compared to a high-pressure EGR, which the company believes remains relatively unproven on lean-burn engines.

The main benefits of WinGD’s iCER technology are reduced fuel consumption, methane slip reduction, combustion stability and zero risk of auto-ignition. Specifically, it provides a reduction in methane slip emissions of up to 50% when using LNG and a significant reduction of fuel consumption, more than 3% in gas mode and 5% in diesel mode.

Building on the successful X-DF platform, the next-generation technologies minimise methane slip in expectation that these emissions will be regulated by IMO to help meet the 2050 greenhouse gas targets. As well as using fossil LNG, X-DF engines can burn carbon-neutral synthetic or bio-derived LNG when it becomes available. By continuing to develop combustion control and engine efficiency, WinGD is improving the performance of its engines using these fuels and minimising fuel costs for ship owners and operators.

This order for iCER technology is considered proof that more shipowners see the importance of investing in green-technology, keeping their options open for future fuel flexibility.
