Abstract:Three-dimension finite element model of JZ20-2MUQ platform is built. By using the method of dynamic finite element analysis of dynamic characteristics for the platform is made, and its preceding 10 modes are obtained. The calculating results quite close to the testing results shows that calculating model of the platform is correct. On the basis of the analysis, the effect of structural factors on the dynamic characteristics of the platform is investigated. Conclusions drawn from the analysis can be used in dynamic design or modification of the platform.
Keywords:finite element  offshore platform  dynamic characteristics  structural factors
