摘要
改装设计的养殖工船因养殖需要在主甲板上增设了多个吊机,而且高度已经对驾驶室视线形成了遮挡,位于船中的海工吊及前部的起重机小吊形成的遮挡比较分散,两个遮挡区域之间的角度小于5°,常规的作图方法满足不了法规中对视域的要求,如果通过改变吊机布置位置来达到要求会影响船舶功能。为解决养殖工船视域盲区间角度小于5°问题,在实现主甲板上吊机功能前提下,通过合并两个区域,达到了两个盲区之间角度大于5°的要求。此方法可将视域中多个分散的小角度视线盲区合并,以达到法规对于盲区之间的角度小于5°的要求,此作图方法可应用于对类似于养殖工船甲板布置的船舶。
To meet aquaculture demands,modified aquaculture vessels usually have several cranes added on the main deck,and the cranes are high enough to block the navigation bridge visibility.The middle crane and the crane at the front form scattered blind sectors,and the angle between the two blind zones is smaller than 5°.With the conventional drawing method,the legal requirement for the bridge visibility can’t be met,while if the requirement is to be met by changing the crane layout position,then the ship functions will be affected.In order to solve this problem of the angle being smaller than 5°,a method is proposed in this paper,that’s to combine the two zones while ensuring the function realization of the cranes on the main deck,so that to increase the angle between the two blind zones to larger than 5°,and meet the legal requirement on visibility.This method can be applied to ships with similar deck layout with that of aquaculture vessels.
