Seasafe is a modular system based on the geometrical definition of the vessel. All Seasafe projects require a geometric definition of the hull, together with as many internal compartments as are needed to support the type of work being carried out. The hull form is modelled using a set of longitudinal curves built up of B-Splines. Items external to the hull can also be defined, such as rudders, deckhouses etc that may contribute to buoyancy, or perhaps required for graphical purposes. For semi-submersible offshore platforms, see the PLF package.

            Additional information is added to the database, dependent on use. Such information can include reference points such as unprotected or weathertight opening, intact and damage stability criteria (all standard stability criteria are predefined), wind areas and wind pressure profiles, lightweight distributions for longitudinal strength - together with their associated shear force and bending moment permissibles, moments such as lifting or towing, and user-defined loads as input for cranes, deck areas etc.

            Seasafe has a comprehensive range of analytical programs that can study the following functions:

• Hydrostatics & cross curves
• Analysis of loading conditions [now using GStab]
• Intact, damage stability analysis (against all current regulations such as IMO, SOLAS etc) [now using GStab]
• Longitudinal strength (sheer forces, bending and torsion moments) [now using GStab]
• Grounding calculations (single, two point and shelf grounding) [now using GStab]
• Oil outflow calculations [now using GStab]
• Intact and damage stability for ranges of conditions (sets of draughts/trims or displacements/trims, against all current regulations such as IMO, SOLAS etc) [now using GStab]
• Probabilistic damage stability for passenger and dry cargo ships [now using GStab]
• Production of Sounding tables
• Production of Bonjean tables
• Grain stability [now using GStab]
