Abstract: The drill floor structure, which supports the drilling modules of the drillship or drilling unit, should not only meets the requirements of the operation function, but also restricted by the hull dimensions and weight control, and different design schemes should be developed quickly for comparison and selection in the preliminary design stage. Under this background, based on the secondary development function provided by NAPA Designer, a parametric design module of drill floor structure is compiled, which drives the creation and update of the parametric model of the drill floor through data interaction. In addition, various design schemes are quickly provided for comparison and selection, and furthermore, finite element models are exported for structural strength analysis. Through a real ship project, it has been proved that the parametric design method of drill floor structure based on NAPA Designer can reduce the user threshold and significantly improve the design efficiency.

摘要： 钻台作为钻井船或钻井平台中钻井模块的载体,既要满足作业功能的需求,又受到主船体尺度和重量控制等因素的制约,故在初步设计阶段需快速制定不同设计方案供比较选择。在此背景下,该文基于NAPA Designer软件提供的二次开发功能,编写了钻台结构参数化设计模块,通过用户自定义界面数据交互驱动钻台参数化模型的创建和更新,可实现快速提供多种设计方案进行比选,并导出三维有限元模型用于结构强度的分析校核,从而得到钻台结构的优化设计方案。经过实船项目测试表明,基于NAPA Designer软件的钻台结构参数化设计方法可有效降低使用者门槛并显著提高设计效率。
