PLF is a modular system based on the geometrical definition of the vessel. It is tailored  to define and calculate the stability of semi-submersible offshore platforms. It enables the definition of a platform type structure, the production of hydrostatic data, as well as the intact and damage stability analyses.

           The PLF geometry definition programs themselves allow the definition of relatively simple structures such as cylinders, cones, box-type shapes etc, which together make up the overall structure. These are economically defined by allowing repeat shapes to be copied, therefore requiring only one definition of each unique part.

           If more complex shapes require to be defined, such as pontoons, which are effectively ship-shape, then the PLF system ‘borrows’ the definition programs from the SIKOB system (included in the PLF package), which can then be referenced and integrated into PLF.

           Additional stability related data can then be defined. These include 3-D wind areas and pressure profiles, stability criteria, reference points etc.

           Once this database of information has been made, a set of application programs can be run which allow the study of the following:

• Hydrostatic data
• Loading condition analysis [now using GStab]
• Intact and damage stability for any axis of inclination [now using GStab]
• Longitudinal strength [now using GStab]
