为了得到安全经济的渔船船体冰区加强结构形式，对冰区加强区域结构分别根据BV船级社规范和CCS钢质海船规范进行计算，为了得到直观的计算结果，选出按BV规范计算得出的钢材重量最轻的方案进行有限元直接计算，根据直接计算结果得到钢材强度的利用率，对比发现由于两部规范的冰区加强部分适用船型较广且针对的海域有所不同，其加强内容不是根据渔船特有的作业特点制定的，所以有必要区分商业运输船和渔业捕捞船的工况，针对相应的航行海域选择合适的规范和冰级。
為瞭得到安全經濟的漁船船體冰區加彊結構形式，對冰區加彊區域結構分彆根據BV船級社規範和CCS鋼質海船規範進行計算，為瞭得到直觀的計算結果，選齣按BV規範計算得齣的鋼材重量最輕的方案進行有限元直接計算，根據直接計算結果得到鋼材彊度的利用率，對比髮現由于兩部規範的冰區加彊部分適用船型較廣且針對的海域有所不同，其加彊內容不是根據漁船特有的作業特點製定的，所以有必要區分商業運輸船和漁業捕撈船的工況，針對相應的航行海域選擇閤適的規範和冰級。

In order to get safe and economic form of fishing vessel hull structure, the ice strengthening structure is calculated and analyzed according to the BV rules and CCS steel ship classification rules respectively.The lightest steel weight scheme satis-fying BV rules is chosen to carry out the FE direct analysis, to get the steel strength utilization.The comparative study on two rules shows that, the ice strengthening of the two rules is widely applicable for different sea areas, but the ice strengthening con-tent do not take into account the unique operations characteristics of fishing vessels.So it is necessary to distinguish the operation condition between merchant ships and the fishing vessels, and choose the appropriate specifications and ice class for the corre-sponding navigation waters.
