This paper presents a continuation of the projects [5, 6] dealing with the novel concepts of evacuating people from large passenger ships. A novel integrated drive and control system for chain lift with lifeboats fastened on it as well as for stern port- ramp, is presented. Additional novel elements is the application of the stern port - ramp fitted with a buoyancy element, and its increased capability of automatic adjusting its operational deflection in the case of a large forward trim of ship. It increases safety and comfort of evacuation in the difficult conditions, but to obtain it a more complex drive and control system has been required to be designed.
