摘要:随着渔业的节能减排工作日益提上日程,对渔船的能效水平评估显得尤为重要。本文参考国际海事组织(IMO)通过的常规船舶能效设计指数(EEDI)计算公式及参考线公式,基于部分拖网渔船资料,提出了适用于拖网渔船的EEDI计算公式,并运用统计回归的方法得到了拖网渔船EEDI参考线公式。利用该公式,实例计算了一艘拖网渔船的EEDI值,并与满载时的计算值以及参考线公式计算值进行了比较,结果显示,拖航时的EEDI值较大。公式有一定的适用性,为国内拖网渔船设计提供参考,也为渔业船舶的节能减排提供新思路。

Abstract: With the energy-saving and emission-reduction work for fishery has been being on the agenda, the energy efficiency level assessment for fishery ships is particularly important. This paper is proposing the EEDI (Energy Efficiency Design Index)formula for trawlers, referring to the conventional ship EEDI formula adopted by IMO(International Maritime Organization), as well as its reference line by using statistical regression method, basing on the ship data of several trawlers. The formula is useful for the trawler design, and will provide a new way for fishery ships’ energy-saving and emission-reduction.
Key words: trawler; statistical regression; EEDI; reference line; energy-saving and emission-reduction
