Abstract
Previous work developed simulation components for ship mechanical systems, including cables, winches, cranes, and payloads. The payload modelling includes treatment of collisions, such as those that can occur when cargo being lifted by a crane strikes the side of a ship. The payload modelling also includes treatment of hydrodynamic forces in calm water and in waves. This report describes improvements made to simulation components to achieve increases in both fidelity and computational speed. Verification and validation of simulation components were performed using test cases of varying complexity. A launch and recovery example demonstrates the usage of crane and payload models when deploying a small boat from a large ship in waves. A towing example demonstrates the usage of the cable model when a naval frigate is towing a tuna clipper.
