辽宁省木质渔船载重线勘画的研究

Marking loadline of wooden fishing vessels in coastal areas of Liaoning Province

针对辽宁省大多数的木质渔船无图纸、确定公约船长并勘画载重线有困难的实际问题,对辽宁省主要沿海地区典型木质渔船进行了测绘、倾斜试验和稳性计算。在统计分析的基础上,提出公约船长(Lc)与甲板长(Ld)的关系为Lc=0.883Ld,公约船长的中点距艏柱内缘甲板处的距离(Ldf)与甲板长的关系为Ldf=0.473Ld,并提出勘画永久性载重线标志的方法。

In this paper, surveying and drawing, inclination experiment and calculation of stability were conducted for classic wooden fishing vessels without drawings in coastal area of Liaoning province. The convince length Lc was found to be the length of deck Ld and Ldf which is the distance from inside of stem to the center of convince length of 0. 473Ld which is the length of deck. The suggestion of permanent mark of marking loadline is proposed. The method is simple, reliable and practical, and has the referential value, which is excellent for the work of marking loadline on wooden fishing vessels in Liaoning province.
