[The Hwankyung Ilbo] The Ministry of Oceans and Fisheries plans to expand the project to convert Yard Tractor fuel from diesel to liquefied natural gas (LNG) in order to reduce harmful exhaust gas generated from the port. The government will spend 1,025 million won on the project this year.
Yard Tractor is a typical harbor loading equipment that transports containers within a pier and there are 947 tractors operating in major ports nationwide, including Busan, Gwangyang and Incheon. The tractor, using diesel as the main fuel, has been pointed out as a major cause of fine dust and greenhouse gas emissions such as carbon dioxide (CO2).
Accordingly, the Ministry of Oceans and Fisheries has promoted the projects to convert diesel-fueled Yard Tractors into LNG-fueled ones and completed converting 107 tractors by the end of last year.
When using LNG fuel, no particulate matter (PM) was generated, which causes respiratory disease, and the amount of carbon dioxide (CO2) and methane (CH4) decreased by 24.3% and 95.5%, respectively, compared with conventional diesel fuel.
In addition, LNG is relatively cheaper than diesel fuel, resulting in a fuel cost savings of about 32.1%. Vibration and noise were reduced, which was found to be effective in improving the port environment, reducing costs, and improving working conditions, such as lowering the fatigue of off-site workers.
"The expansion of the fuel conversion project of the yard tractor, which is the main equipment used in the port, is expected to help reduce the emission of harmful substances and build a green port," an officer of the Ministry of Oceans and Fisheries said. "We plan to improve the system to expand the project for small terminals and other mobile harbor loading equipment. "
