An integrated hydraulic drive system of a novel device for launching lifeboats from large passenger ships

Dymarski C.

Polish Maritime Research

nr 1

3-10

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.

A concept of drive and control system of a novel device for people evacuating from large passenger ships

nr 4

54-58

Year-after-year increasing number and size of sea-going passenger ships make it necessary to search for novel methods of evacuation of passengers from such large objects or to improve those which have been applied so far. This paper presents a concept of one of the original methods, in which, a.o., chain lifts have been applied to hold up life boats during voyage as well as to launch them in case of evacuation. Technical assumptions and requirements as well as schematic diagram of the hydraulic drive and control system of the lift, is presented.
