ABSTRACT

The structural integrity of platform components under operational loads and environmental storm conditions is required for risk assessment and inspection plan development. In-place analysis was performed to verify that the platform structural members have the robustness and capability to support the loads in operating and storm conditions. A finite-element analysis is adopted to estimate the in-place behavior of a typical fixed offshore platform for reassessing design parameters based on measured performances. The SACS software is employed to find the dynamic characteristics and the displacement responses of platform consistent with in-place analysis aligned with the stresses at selected members and joints are examined based on unity checks. The directions of environmental loads and water depth variations have significant effects on the results of the in-place behavior. The results confirm that the in-place analysis is quite essential for the reliable design of the offshore platform and assessment of existing offshore structures.

固定式海上平台设计水平评估的就地分析

摘要

风险评估和检查计划的制定需要平台组件在操作负载和环境风暴条件下的结构完整性。执行就地分析以验证平台结构构件具有在操作和风暴条件下支撑载荷的坚固性和能力。采用有限元分析来估计典型固定式海上平台的就地行为,以根据测量的性能重新评估设计参数。使用 SACS 软件来查找平台的动态特性和位移响应,与在选定构件处的应力对齐的就地分析一致,并基于统一检查检查节点。环境荷载的方向和水深变化对就地行为的结果有显着影响。结果证实,就地分析对于海上平台的可靠设计和现有海上结构的评估非常重要。
