Study and optimization of energy storage system for saving fuel consumption of ship's generators by self-made simulation using actual ship data

■　Overview
My research focuses on whether the installation of an energy storage system using lithium-ion batteries in a ship's AC power system is effective in reducing the fuel consumption of the ship's generators. We are also studying what are the optimal power output and capacity of the energy storage system. Based on data measured on actual vessels, I have created our own simulation to reproduce the energy flow of the ship's power system.


■　Self-introduction
My name is Norichika Nagayama, a first-year student in the Master's Course in Marine System Engineering. After graduating from the Department of Marine Electronics and Mechanical Engineering, I went on to Advanced Onboard Training Course for Mercantile Marine(the Engineering Course) and entered graduate school in October 2022. In extracurricular activities, I am a member of the American football team at my alma mater (high school) as a student coach. I look forward to working with you.

Proposal for Fuel Consumption Reduction Operation of Shioji Maru Based on CPP Characteristics


■　Overview
Reducing fuel consumption has been a longstanding issue for marine transport operators. In particular, coastal shipping and fisheries have been severely affected by the recent sharp rise in crude oil prices and the shift in trend from long-term yen appreciation to yen depreciation. The reduction of fuel consumption is therefore a major demand of the times. Based on this social phenomenon, this study focuses on methods to reduce fuel consumption in the Shioji Maru.
