Quantitative Analysis for the Development of Maritime Transport Efficiency

摘要

This paper analyzes the maritime transport efficiency which include ships' quantitative analysis of four main kinds. Nearly 90 percent of the world total trade of goods measured in tons are moved by sea. And vessel's transport efficiency is higher than the other vehicles, so ship is regarded as an epitome of science and technology. The development of ships is achieved by technological innovation, the innovation is the fundament, Now using the principle of transport efficiency to analyze the historical development of transport vehicles is needed .Transport efficiency is the energy efficiency used for transport facilities, which is expressed as η=1/h_(fs foc)·wv/p·w_p/w In the historical time, ship's size, speed and engine output power have changed largely. And this paper will discuss base on the basic formulas and statistics of four kinds of ships: bulk carriers , LNG carriers ,oil tankers and container ships.
