据国际风帆动力船舶协会（IWSA）估计，到今年年底，约有25艘大型商船将安装风力辅助推进系统，其运力达120万载重吨；到2023年底，将有多达50艘大型船舶利用风能辅助航行，总吨位超300万载重吨。此外，最近已有10艘小型游轮采用传统柔性帆技术，注册总吨位达5万吨。鉴于燃油价格仍保持高位，而风能又具有可观的经济潜力和脱碳能力，对于船东们来说，利用风能为船舶提供动力将越来越具有吸引力。IWSA还称，改进后的风力辅助推进方案能解决船舶5-20%的能源需求，对于经过优化的新船，这一数值甚至可以达到30%。

    According to the International Windship Association (IWSA), at the end of this year, about 25 large commercial ships will be installed with wind propulsion systems, which will represent a total cargo volume of 1.2 million deadweight tons. IWSA estimates that by the end of 2023, as many as 50 large ships will utilize wind energy to carry cargo with a total tonnage of more than 3 million deadweight tons. In addition, 10 small cruise ships have adopted traditional soft sail technology, with a total registered tonnage of 50000. Considering the high fuel price and the considerable financial and decarbonization potential of wind power, wind power will become an increasingly attractive choice for ship owners. According to IWSA, the improved wind assistance solutions can save 5-20% of the ship's fuel use while the power requirement, with potential to reach 30%.

Deadweight Ton n. 载重公吨位

Tips：载重吨（DWT）是衡量船舶载重能力的指标，普遍以吨计量，吨有英吨、美吨、公吨的区别。英吨计2,240磅；美吨计2,000磅，公吨计1,000千克。
