Hydrostatic Calculations

When a satisfactory hull definition is available, inclusive of any appendages, then the following computations can be performed:

• Hydrostatic properties for various drafts and trims.

• Cross curves of stability allowing for free or fixed trim.

• Critical KGs or GMs for intact stability.

• Permissible grain heeling moments.

• Deadweight Table and Scale.

• Freeboard in accordance with the 1966 Loadline Convention.

• Curves of floodable length in accordance with the SOLAS 1974 Convention.

• Axis shift stability for offshore structures.

With the internal compartmentation defined as well as the mainhull and appendages, the following Naval Architectural calculations can be carried out:

• Tank calibrations.

• Grain calibrations with trimmed and untrimmed ends.

• Compartment free surface, volumes and centres of gravity for full or partly filled tanks.

• Damaged stability righting levers, damaged hydrostatics and trim, resultant waterplane characteristics and damaged critical KGs or GMs for any number of damaged conditions and permutations.

• Righting levers, an assessment of criteria fulfillment and resultant critical KG's for any number of loading conditions.

• Probabilistic stability assessment according to SOLAS Cargo Ship Rules and the Passenger Ship (IMO Res.A265) Rules.

• Still water vertical bending moments, shearing forces and peak shearing forces for both intact and damaged cases.

• Stability and static longitudinal vertical strength calculations on a regular wave profile and at any heading.

• Way end and fore poppet pressures plus moments of weight and buoyancy for a series of travels during launching. Also velocity-time curve prediction for launch dynamics.

• Transverse and vertical grain heeling moments for partly filled holds.

• Gross and net tonnage in accordance with the 1969 Convention.

• Results of Inclining Experiments.
