AbstractDesign of a model scale lifeboat deployment system is presented. The lifeboat deployment system facilitates testing of physical model lifeboats. It is comprised of a controlling application and three core subsystems; a wave timer, two davits and associated controllers, and a boom and associated controller. The controlling application presents an intuitive graphical user interface and provides configuration and operational control of the entire system. The wave timer analyzes data from a wave probe to determine the optimum time a lifeboat should be launched. This process ensures the lifeboat lands on the least dangerous part of the wave phase. The wave timer and automated launch capability enable researchers to study the effects of deploying the lifeboat at differing wave phases. The davits and controller subsystem raises and lowers the lifeboat at user specified controlled rates. The boom and controller subsystem orients and propels the lifeboat away after launch. The angle of the boom, which is dependent on boom load, is continually adjusted by a simple closed loop feedback system. Discussion of the design requirements and implementation of this system are presented.
