  • CargoMax - Vessel Loading Program

    CargoMaxTM is a shipboard loading calculation program which is used for planning and evaluating ship loading. It quickly and precisely calculates ship stability and stress characteristics based on any loading condition specified by the user. For over 20 years it has proven itself a valuable tool to maximize vessel utilization, increase cargo loading efficiency, increase crew productivity, monitor margins of safety during load/discharge, and improve safety (reduce human error). Numerous options are available to provide even greater utility for specific crew operations.
