Evaluation Method for Energy Saving of Sail-Assisted Ship Based on Wind Resource Analysis of Typical Route

Sail-assisted technology can reduce greenhouse-gas emissions by saving the energy consumption of ships with wind utilization. The distribution characteristics marine resources are critical to energy-saving effect sail-assisted ships. However, due lack effective evaluation methods for improving utilization rate energy, a high potential still exists. A novel method based on resource analysis typical ship routes is proposed in this paper. First, three-degree-of-freedom motion model considering wing sail forces constructed. Then, acquisition and spatial–temporal interpolation proposed. On basis, field probability matrix force established. Ultimately, an combining sailing condition case study results show that oil tanker sailed China-to-Middle East route was more than 5.37% 2021 could reach 9.54% single voyage. It great significance realize popularization application technology, thus greenization shipping industry.
