Abstract: Fire compartmentation is one of the most important and complicated ship general design work, especially for the passenger ships, such as the cruise ship and Ropax with large number of rooms. The traditional design method, which is based on two-dimensional (2D) drawings and human subjective judgement, costs heavy workload and is likely to induce mistakes. A three-dimensional (3D) assisted fire compartmentation method for ship cabins has been proposed based on the secondary development of the 3D modelling software UG through the programming analysis of the specification requirement logics. This method embeds the relevant knowledge requirements of the fire protection rules. It fulfils the functions of customizing the categories of the ship cabins, automatically creating the common interface of adjacent cabins, and automatically setting the common interface’s fire protection level, which is highlighted in different colors, according to the regulations. It also counts the usage of different fire protection levels, which can lay the foundation for helping the designers to optimize the cabin arrangement based on the objective of reducing fire protection materials.

摘要： 防火区域划分是船舶舱室设计重要且繁复的总体设计工作,尤其对于舱室众多的豪华邮轮和客滚船等客船类船型,传统的设计方法基于二维图纸、依靠人为判断划分,工作量极大且容易出错。通过对规范要求逻辑的程序化解析,基于三维建模软件UG采用了二次开发方法,该文提出了一种船舶舱室防火区域三维辅助划分方法。该方法嵌入了防火规范相关知识要求,实现了自定义船舶舱室类别属性、自动创建毗邻舱室共界面、根据规范自动设定公界面防火属性并以不同颜色突出显示等功能,还提供了不同防火类别使用情况的统计功能,为辅助设计者以精简防火材料为目标优化舱室布置奠定了基础。
