一、前言

  SESAM （Super Element Structure Analysis Module）是由挪威船级社（DNV-GL）开发的一款有限元分析（FEA）系统，它以 GeniE、HydroD 和 DeepC 等模块为核心，主要用于海工结构的强度评估、波浪荷载计算和系泊系统分析等。GeniE、HydroD 和 DeepC 分别是 Sesam 系统的固定式结构分析模块、漂浮式结构分析模块和系泊系统分析模块。HydroD is the software package for robust hydrodynamic analysis and stability analysis.

  在 HydroD 中，可以进行浮体的水静力分析（Hydrostatic）和水动力分析（Hydrodynamic）。水静力分析是在 HydroD 内部实现的，水动力分析则需调用 Wadam（频域）或 Wasim（时域）程序。在 HydroStaticAnalysis 文件夹下，可以定义的静水力分析有三类：AVCGAnalysis、HydroStaticRuleChecks 和 StabilityAnalysis。

二、稳性分析

  Stability analyses depend on loading conditions and location. In addition you may decide upon start and end of angle interval where you want to compute. Wind influences stability as heeling moments and it is thus necessary to include it in the stability calculations. The purpose of a load cross section is to define where HydroD shall compute still water forces and bending moments during hydrostatic analysis.

三、Hydrostatic Rule Checks

  When the hydrostatic analysis has been performed, hydrostatic rule checks may be carried out based on various given codes. IMO、MARPOL 和 IGC 分别是国际海事组织、国际防止船舶造成污染公约、国际地理大会的缩写。

四、AVCG Analysis

  An AVCG analysis is an analysis where the maximum allowable vertical position of the centre of gravity according to a specified rule set, is computed for a (normally large) number of intact and damaged loading conditions. There are several Rule sets to use in these analyses. A part of the analysis is to find the most critical rotation axis. The range of axis directions to search through is defined by the user.
