Critical pointsThis extension allows for the input of critical points and openings (e.g. ventilation openings, down-flooding points, deck edge points, weather tight openings and tank connections). These points are mostly used during the evaluation of stability criteria and are required by the following extensions:

  • Load cases (intact stability)
  • Probabilistic damage stability
  • Deterministic damage stability
  • Cross curves extension
  • Max. allowable VCG' extension
  • Floodable length curves

The use of critical points gives the designer a clear understanding of when specific events such as deck immersion or downflooding occurs (output of displacement, heeling angle, trim and draft. For damage stability calculations weathertight openigs and tank connections can be specified.
