Wind Energy Conservation of Global Trade Routes Based on Oil Tankers

Abstract

Sail-assisted Ship is an effective way to use wind energy to improve the green level of ships. The distribution characteristics of offshore wind resources are very important for sail-assisted ships, but there is still no effective energy-saving evaluation method to evaluate its utilization rate. This paper calculates the energy saving effect on the main trade routes based on wind resource analysis. Taking the large oil tanker with wing sail as the research object, the ocean wind resources in the sea area of the world’s main trade routes are analysed by spatiotemporal interpolation method. Wind resource information on trade routes was obtained, a model was built based on wind field probability matrix and thrust load matrix during full load sailing, and the wing sail energy saving effect was calculated. Based on this model, the annual energy saving effect of large oil tankers on main routes was analysed. Finally, combined with the actual sailing condition of the ship, the energy saving evaluation method of the sail aid ship on the typical route is proposed .The conclusion shows that if the popularization and application of sail aid technology can improve the energy efficiency of ships, it is of great significance to the green level of shipping industry.
