In addition to performing the usual calculations relating to stability, sheer forces and bending, the software enables the weight of the cargo to be calculated from the vessel’s draught marks and, in the case of general cargo and specialised heavy-lift vessels, predicts the degree of list anticipated when lifting heavy loads, all within 10–15 minutes. The system can provide print-outs for attachment to the ship’s log.
StabPRS also predicts the motion of the vessel in irregular sea states and displays a motion simulation showing exactly what the ship is likely to experience. Should the vessel be involved in an incident, StabPRS can calculate the stability and hull stresses when one or more compartments are flooded, showing in graphic form the state of the ship under such conditions in calm water.
Prior to rolling out StabPRS globally in 2008, PRS is working with a number of Polish ship-owners who are providing valuable feedback. Five owners are participating in the project and seven vessels have either been provided with StabPRS software or are about to have it installed. Two further vessels are scheduled to be fitted with it very soon.
