Abstract
Ship-mounted cranes are widely used in transportation and installation of heavy loads to the seabed. To minimize adverse effect caused by harsh environment, the cranes are equipped with compensation equipment for the motion. When we design the compensation equipment for the cranes, anti-sway control algorithms in the equipment should be included. To test the feasibility of the algorithms effectively at the early design stage, the hardware-in-the-loop simulation (HILS) framework can be used as one of alternatives. The proposed method consists of several components: virtual mechanical system based on multibody system dynamics, virtual actuator and sensor, and hardware controller. In this study, it is applied to an example of the anti-sway control of the crane on an offshore supply vessel (OSV) during the installation operation of a subsea equipment using the proposed HILS framework.
