Structural Integrity Analysis of Fixed Offshore Jacket Structures
Keywords:
Offshore jacket structures, load analysis, structural response, stress utilization, foundation utilizationAbstract
Offshore structures which are used to support oil and gas exploration and production facilities are subjected to external loadings such as gravity loads, environmental loads, seismic loads, hydrodynamic loads and accident loads. Physically, the natural responses of the structures are specified in term of displacement and vibration. In this paper, the structural response to external loadings of an offshore structure operating in the Malaysian Water, is measured in terms of stress utilization at structural component level. Offshore structures are designed and assessed to meet the requirement as stipulated in international standards. The type of loading, structural assessment, structural response and utilization checks are discussed. The design of the jacket structure that is studied complies with code requirement with sufficient robustness to withstand either in-service condition or extreme condition.References
