【Abstract】 A new ideal, in this paper, is described that the barge and the jacket are considered as a combined floating body or a joint system before the jacket separating from the barge. And the relative motion between two bodies is completely independent with each other. The relevant mathematical models of the floatation of the joint system and both static and dynamic lever arms are presented. Moreover, in order to evaluate the displacement and the center of buoyancy of the jacket at any time and any position, an accurate and interesting method is introduced to define and describe the jacket′s pipes and the detail calculation process for obtaining the displacement and the buoyancy center of each pipe component. The computer program is developed with this new method. And a practical engineering project is used as an example. The calculational results of intact stability are provided in the paper.更多还原
