摘要：在进行设计之前，首先要对母型船资料进行相应的了解和分析。之后进行的总体设计第一步为通过公式来对设计船的主尺度进行估算。完成估算后，第二步是使用HULLSURFACE模块进行母型船的表面型线设计。在分别完成艏部艉部舯部之后，将三部分联合生成HULL，然后再通过前文计算所得的主尺度进行仿射变换，得到新船的表面型线建模。型线建模的工作彻底完成后，需要新建一个甲板曲面DECK，来使船体成为密闭整体STABHULL。接下来分别在GeometryEditor模块下完成舱室划分工作和在ShipModel模块下完成舱室定义，最后在LoadingConditions模块下进行典型载况的加载，设计船为油船，因此典型载况为满载出港、满载到港、空载出港、空载到港、部分装载出港、部分装载到港这六种。之后就是数据和图表的输出工作，其中主要对象为静水力数据和曲线、邦戎曲线、横剖面面积曲线以及各种载况的稳性曲线等。最后，以上工作都完成之后进行数据和图表的整理计算工作，完成静稳性报告和完整稳性报告。

Abstract：Before the design, first of all to the data of parent ship for a corresponding understanding and analysis. The first step in the overall design is to estimate the main dimensions of the design ship by formula. After completing the estimation, the second step is to use the HULLSURFACE module for the surface profile design of the parent ship. After the completion of the bow stern hereditary part, the three parts are combined to produce HULL, and then through the previous calculation of the main scale of the affine transformation, the new ship surface line modeling. After the completion of the modeling work, you need to create a new deck surface DECK, to make the hull into a closed whole STABHULL. Then complete the pision of the work under the Geometry Editor module and complete the definition of the cabin in the Ship Model module, and finally in the Loading Conditions module under the typical load conditions, the design of the ship for the tanker, so the typical load is full loaded departure, full loaded arrival, ballast departure, ballast arrival, partially loaded departure and partially loaded arrival, some of the six kinds of loading conditions. Followed by the data and the output of the chart work, which is the main object of hydrostatic data and curves, Bonjeans’ curves, cross-sectional area curve and a variety of conditions such as the stability curve. Finally, the above work is completed after the data and chart the finishing calculation work to complete the static stability report and complete stability report.
