外航貨物船の運航実績値に基づくLCAのための海上輸送データ：単位輸送量当たり燃料消費量と大気環境負荷ガス排出量

Abstract

Data for LCI analysis associated with seaborne transportation are very limited although a great quantity of natural and energy resources are imported and various kinds of manufactured products are exported by oceangoing cargo-ships in Japan. Therefore based on logbooks of typical oceangoing cargo-ships, fuel oil consumptions and gaseous exhaust emissions per unit transportation were studied. The studied ships comprise of eight ships, which are categorized in five types of ships, namely, two oil tankers, two bulk carriers, two container ships with different sizes, a pure car carrier and an LNG carrier. Averaged fuel oil consumptions per unit transportation were compared and evaluated with the ones derived from nominal data. Averaged data of navigation were provided such as distances, service speeds, cargo loading factors, and averaged load factors of main engines, diesel generators and auxiliary boilers. The gaseous exhaust emissions per unit transportation derived from the averaged fuel oil consumption include carbon dioxide, sulfur oxides and nitride oxides.
