Eder construction at Tadotsu Shipyard Co., Ltd., part of the Imabari Shipbuilding Group, was delivered to “K” LINE as “K” LINE’s ? rst LNG-fueled car carrier. This vessel is a next-generation environmentally friendly vessel expected to reduce emissions of carbon dioxide (CO2) by approximately 45% based on EEDI, emissions of sulfur oxides (SOx) by al- most 100%, and emissions of nitrogen oxides (NOx) by 80% to 90% by means of Exhaust Gas Recirculation (EGR) in addition to the use of LNG fuel, compared to conventional vessels using heavy fuel oil. This vessel utilizes a variety of environmental measures and digital technologies in an effort to improve safety, environment, and quality that are important issues for “K” LINE.

Environmental: The ship is equipped with a dual fuel main engine and auxiliary engines capable of operating on either

LNG or Marine Gas Oil (MGO). The main engine type is a high-pressure MAN B&W ME-GI for low GHG emissions by negligible methane slip (unburnt gas) and reduced CO2 emis-
