克拉克森统计数据显示,航运业的绿色转型步伐正在加快,船东开始投资氢、氨等替代燃料动力船舶。目前,全球商船队中已有超过320艘“液化天然气预留”船舶,此外还有99艘“液化天然气预留”船舶、130艘“氨预留”船舶以及6艘“氢预留”船舶的订单。超过5,500艘船舶应用了包括导管螺旋桨、旋筒帆和空气润滑等在内的节能技术(EST),占总吨位的24.5%。压载水管理系统(BWMS)的改造也在按计划进行,约占总吨位70.6%的船舶已安装了该系统。超过1,700艘船舶已安装或计划安装岸电连接设备,但拥有岸电系统的港口仅有171个(约6,000个码头),急需加大对港口设施的投资。
The green transition of the shipping industry is picking up pace with shipowners starting to invest in vessels that are technologically prepared to burn alternative fuels such as ammonia and hydrogen. There are now over 320 “LNG ready” ships in the fleet and 99 on the orderbook, while there are 130 “ammonia ready” and 6 “hydrogen ready” vessels on order. Energy-saving technologies (ESTs) have been fitted on over 5,550 ships, accounting for 24.5% of fleet tonnage: this includes propeller ducts, Flettner rotors, air lubrication systems and others. BWMS retrofit programme ongoing: majority of fleet tonnage (70.6%) now BWMS-fitted. Huge investment at ports is needed: only 171 ports (out of ~6,000) have shore side power, while over 1,700 vessels are fitted/set to be fitted with shore power connections.
lubrication n. 润滑
美 /ˌlubrɪˈkeʃən/ 英 /ˌlu:bri'keiʃən/
词根为lubricate“上油”,源于拉丁语lubricare“滑的”,在现代英语中引申为“给……上油”。
Air Lubrication Systems P.n. 空气润滑系统
Tips:船舶空气润滑系统是一种利用空气泡来减少船舶阻力的装置。该装置将空气从船舶底部快速喷出,形成蜂巢状气泡,这些气泡能迅速联合起来,在船体外表面形成1~2cm厚的空气层,有效减少船舶航行时的阻力,提高推进效率,减少燃料消耗,实现节能减排。
