Load effects analysis of high-pile pier skid-way quay while offshore platform loaded to barge whose deck elevation adjusted by aided jacks

摘要

The vertical bearing capacity calculation and security evaluation methods of high-pile pier skid-way quay while large offshore platform moving to barge whose deck elevation adjusted by aided jacks are researched by the theoretic analysis and numerical calculation method. Based on the study, the load effects of 6000ton skid-way quay are acquired under the offshore platform weight and jacks load caused in the process of large platform moving to the barge whose deck elevation adjusted by aided jacks, the security of skid-way is assessed, and the security measures of skid-way structure which should be taken during moving platform are proposed. The analysis of simulation results shows that the bearing capacity of skid-way in vertical meets the requirements of design under the jacks load and platform weight by using uniform pressure to compute. The 6000ton skid-way quay is secure while large offshore platform loaded to barge whose deck elevation adjusted by aided jacks. The conclusions above can provide the experience for the security evaluation of high-pile pier skid-way structure and the optimization of procedure to load the large offshore platform on barge whose deck elevation adjusted by aided jacks.
