MOMENT STABILITY SYSTEM FOR LARGE VESSELS

Abstract

An improved computerized moment stability system is provided which will rapidly obtain the solution to operational and post damage stability problems which may be present on an oceangoing vessel. The system includes three functional modules plus an initialization data base module. The data base modules stores the basic stability data concerning all watertight compartments and tanks onboard the vessel. An operational stability module is provided for performing the operational calculations to determine the stability parameters which exist under normal conditions. In addition, the operational module can provide reports concerning the day to day inventory of consumables as well as help in properly performing the loading and unloading of the vessel to maintain a safe, stable, condition at all times. A stability assessment module is included which performs the necessary calculations for the determination of post-damage conditions and the stability parameters for the vessel after battle, collision or grounding damage has been sustained. The post-damage stability is compared with the predamage stability in the corrective strategy module whereby either operator corrective strategy or system developed corrective strategy can be established for correcting the questionable stability of the vessel. Various corrective strategy analyses can be hypothetically attempted to determine the best strategy to follow. The data base module can also provide a system backup through the production of a complete compartment and tank stability card file for possible post-damage stability analysis for the vessel under emergency conditions.
