The Polish Shipping Register has launched a software package to enable quick and accurate assessments of a ship’s loading condition and consequent stability and strength.
PR claims its StabPRS software represents a major advance in processing data to provide day to day onboard assistance in operating vessels safely. The program calculates the effects of changes in the ship’s loading condition, updates the stability parameters, presents risk levels and predicts likely outcomes. This enables master and crew to take the necessary remedial action. StabPRS calculates traditional stability, shear forces and bending moments, and verifies cargo weight, using draft marks data. The package’s options include verifying wave generated forces affecting heavy cargo lashings; simulating cargo handling by deck cranes and predicting the heel angle of every cargo handling process; planning optimal routes in given wave conditions; and warning crew about exceeding allowable strength and stability parameters. The program operates whether the ship is intact or damaged. For example, it calculates damage stability and hull strength when up to several compartments are flooded.
