Optimization of River-Sea-Going Ship Type Scheme and Operation Strategy Under Emission Control Area in China

Abstract

Throughout Chinese existing river-sea-going ships, there are widespread problems such as chaotic ship types, small average tonnage, serious aging of ships, and low energy efficiency. In order to cater to the requirements of ship emission control areas implemented in China on January 1, 2016, research is carried out on optimization of river-sea-going ship type scheme and operation strategy under emission control area. The lowest cost model of single-ship round-trip voyage is constructed and the ship operation strategies under the emission control zone in China are analyzed. Through discussing the effects of different operation strategies on ship speed, cost and emissions, some suggestions are put forward for the operation of existing river-sea-going ships. At the same time, combining the optimization of design speed with the optimization of ship form schemes, a design speed model of river-sea-going liner based on penalty cost is proposed, and a comprehensive evaluation index system of river-sea-going liner form schemes based on technological advancement, environmental protection and economy is constructed. Systematic optimization of river-sea-going ship type scheme provides an effective way for the preliminary design of the river-sea-going ship, in line with the current river-sea-going shipping background of energy saving and emission reduction in China.
