世界上最大的邮轮公司——嘉年华邮轮集团宣布,将在2027年之前为旗下大部分邮轮安装空气润滑系统。这一举措能够为每艘船舶减少约5%的船体阻力,将大幅降低整个船队的燃料消耗和碳排放。目前,有五艘邮轮正在安装Silverstream空气润滑系统ALS,嘉年华集团还计划在旗下超过一半的邮轮品牌中,为其现役或新建的至少十艘邮轮安装该系统。随着时间推移,此项目还将不断扩大。空气润滑系统通过空气释放装置泵出大量的微小气泡,在船体底部形成一层“空气毯”,以减少水与船体表面之间的摩擦阻力。此外,嘉年华集团还承诺到2030年将碳排放基线较2019年降低20%,并期望于2050年实现碳中和。
Carnival Corporation & plc, the world’s largest cruise company, is expanding the installation of air lubrication systems to the majority of the cruise line brands in its fleet through 2027. The cruise major expects to generate significant savings in fuel consumption and carbon emissions by reducing hull resistance by approximately 5% per ship. Carnival is currently installing the Silverstream System ALS on five ships. In addition, the company is planning at least 10 more installations for existing and newbuild ships across more than half of its cruise line brands, and it expects continued expansion of the ALS program over time. The system pumps tiny bubbles through air release units on the hull to reduce friction between the vessel and the water, helping it glide through the ocean. On the same time, Carnival Corporation has committed to reducing carbon emission intensity by 20% from its 2019 baseline by 2030 and has set an aspiration to achieve net carbon-neutral ship operations by 2050.
resistance n. 电阻,抵抗,阻力
美/rɪˈzɪstəns/ 英/rɪˈzɪst(ə)ns/
该词由动词resist加上名词词尾-ance构成。resist前缀re-表示“回,向后”,词根sist源于拉丁语sistere,表示站立,合起来直译为“站立在相反的一面”,引申为“阻挡,抵抗”。
hull resistance P.n 船舶阻力
Tips:船舶阻力是指船舶航行时,作用于船体上阻止船舶运动的力,包括空气阻力和水阻力。在一般民用船舶中,空气阻力仅为总阻力的2% ~4%。水阻力包括两部分,一是突出于船体以外的舵、轴和批龙骨等所受的附加阻力;二是船体本身所受的阻力即裸体阻力。附加阻力一般仅占总阻力的3%~10%。船舶阻力会使航行速度降低,进而引起燃油消耗和对应污染物排放的增加。
