Open publisher page 0 citations

Abstract

The pinion and rack jacking system is the most important bearing apparatus of the jack-up platform.It has to support the platform itself,equipments on it and external loads.Thus the jacking system bears heavy load for long time.In this paper,the most commonly used three legs jack-up platform was selected for analyzing the load acted on the jacking system,by means of internal force of the legs.Results of the research can be used for the safety evaluation and life prediction of the jacking units.
