基于标准船型评价指标的近海渔船船型发展分析

Analysis on the development of offshore fishing vessel type based on evaluation index of standard ship form

为了给渔船研究方向以及相关政策法规的制定与修改提供参考。针对目前中国对渔船发展情况分析多为定性描述的基本情况,以浙江省近海主流的刺网和拖网船型为例,通过标准船型评价方法中量化指标的计算,分别对1990-1999年、2000-2009年和2010-2019年3个年段的船型各系数进行分析,对体现船型"安全、节能、经济、环保、舒适"5个指标的相关系数进行定量的计算与比较,进而分析近海渔船船型的总体情况与发展趋势。研究发现,除空船重量系数、固定压载系数、平均稳性衡准数等参数对应的性能略有下降外,其余如船型的海军部系数、鱼/油舱容积系数、拖力系数等参数均呈现了良好的态势,总体上船型发展趋势较好。

In order to provide reference for the research direction of fishing vessels and the formulation and revision of relevant policies and regulations,considering that the analysis of the development of fishing vessels was mostly qualitative description of the basic situation at present,the gill net and trawl ships in coastal area of Zhejiang Province were taken as examples,the coefficients of ship form in 1990-1999,2000-2009 and 2010-2019 were analyzed and the quantitative calculation and comparison were made on the correlation coefficients of the five indexes of ship form,namely safety,energy saving,economy,environmental protection,and comfort through the calculation of the quantitative indexes in the standard ship form evaluation method,and the overall situation and development trend of offshore fishing vessels were also analyzed.Result shows:except for the performance corresponding to empty ship weight coefficient,fixed ballast coefficient and average stability criterion was slightly degraded,other parameters such as navy coefficient,fish/oil tank volume coefficient and drag coefficient of ship form showed a good situation,and the development trend of ship form was good on the whole.
