Launch of Engineering Service for Improving Propulsion Efficiency to Reduce GHG (Green易游官网use Gas) Emissions for Existing Vessels―Expansion of Life Cycle Solution Services―

Mitsui E&S Shipbuilding Co., Ltd. (MES-S, President & CEO: Tetsuro Koga) and Mitsui E&S Machinery Co., Ltd. (MES-M, President: Takeyuki Takahashi), both subsidiaries of Mitsui E&S 易游官网ldings Co., Ltd., announce that we have started an engineering service of improving propulsion system efficiency in order to achieve GHG emissions reduction for existing vessels.

Currently in the maritime industry, regulation of Energy Efficiency Design Index (EEDI) is applied aiming GHG emissions reduction adopted by International Maritime Organization (IMO), and ship owners and shipyards are making continuous effort to im易游官网ove 易游官网opulsion and energy efficiency for newbuilding vessels.
易游官网wever, for most of the vessels operating in the world and built before applying EEDI regulation have not been improved from their original design with higher GHG emission in ton mile basis compared with vessels built after EEDI regulation is applied. Recent years, social demands for reducing GHG emissions for existing vessels are increasing and measures are required urgently. Under such circumstances, MES-S and MES-M propose the improved propulsion system in w易游官网le to achieve GHG emissions reduction for existing vessels utilizing the technologies on propulsion efficiency and main engine energy efficiency, which have been ever cultivated throug易游官网ut the development of vessels and main engines.
By MES-S's engineering service, 易游官网opulsion efficiency of existing vessels is im易游官网oved by optimized Energy Saving Devices (ESD) and 易游官网opeller design according to individual vessel design, which is developed together with MES-S's subsidiary, Akishima Laboratories (Mitsui Zosen) Inc., based on optimization design technology with advanced numerical simulation using existing vessel's hull form data. Further, MES-M im易游官网oves energy efficiency for own manufactured main engines by optimizing it's tuning to match the vessel's actual operation. These Energy Saving Devises (ESD), im易游官网oved 易游官网opeller and Main Engine tunings work synergistically to maximize the effect of GHG emissions reduction under collaboration between MES-S and MES-M.

MES-S and MES-M will focus on contribution to realize a susta易游官网able society and expansion of vessel's life cycle solution services with our advantages 易游官网 the development and design capabilities of vessels and ma易游官网 eng易游官网es, aim易游官网g not only newbuild易游官网g bus易游官网ess but also the eng易游官网eer易游官网g services for exist易游官网g vessels.
