Abstract

Oil and gas pipelines are susceptible to various forms of damage where repair mechanisms have since been developed for rehabilitation. Once installed, structural health monitoring often incurs excessive costs and defects rectification of the repaired pipeline becomes a major challenge. Finite element analysis (FEA) provides a rapid route to predict the behaviour of the rehabilitated pipelines under prescribed in-service conditions. In this paper, burst strength of a commercially available composite sleeve repair system, Helicoid Epoxy Sleeve (HES)™, which combines the use of carbon fibre strip and epoxy grout as reinforcement to damaged pipe, was investigated through experimental and numerical approaches. Design standards for subsea pipelines are used in the calculation of design pressure and burst pressure. In the experimental setup, API 5L X52 steel pipe was machined with 50% metal loss defect in wall thickness to simulate external corrosion. Results from design calculations, experimental and FEA showed good correlation with margin less than 10%.
