Structural integrity assessment and life extension study for an offshore production platform
AETERNA conducted a comprehensive structural integrity assessment of an aging offshore production platform. The study included underwater inspection (ROV), topside NDT, cathodic protection survey, and structural analysis using SACS software to evaluate remaining life and fitness-for-service.
25+ years in service, exceeded original design life
ROV underwater inspection, topside NDT, CP surveys
15+ years additional safe operating life demonstrated
The platform had exceeded original design life with limited documentation. Harsh offshore environment required specialized inspection techniques. Corrosion under insulation and marine growth obscured critical structural elements.
Our multidisciplinary team performed ROV-based underwater inspection of jacket structure, topside UT thickness measurements, and CP potential surveys. Structural analysis using SACS assessed wave loading and member utilization. We delivered a detailed life extension plan with prioritized remedial recommendations.
