THEORETICAL SEAKEEPING PREDICTIONS ON BOARD SHIPS - A SYSTEM FOR OPERATIONAL GUIDANCE AND REAL TIME SURVEILLANCE

A prototype of an on board based guidance and surveillance system for wave-induced effects on ships has been developed. The system includes a complete model of the ship for direct hydrostatic and hydrodynamic analysis of arbitrary operating conditions. The sea state is evaluated from measurements of the ship motions. Criteria for warnings of non-desired events can be initiated on board. The system can work as an automatic real time monitoring system which will alert the bridge officer when risk levels are exceeded. At the same time advice can be given on changes of speed and heading that will decrease the risk. The system can also be used in a manual mode for analysis of forthcoming situations in order to optimise the operation of the ship.
