|Design Code||ISO 24817 & ASME B31.8|
A 500mm NB gas riser on an offshore platform had experienced significant wall thinning due to external corrosion below the platform sea deck. A TechnowrapTM solution was provided which met the required standards of ASME B31.8 (gas transmission and distribution, as an AEA class 3 pipe repair) and ISO 24817 with structural loadings for axial and bending moment. The repair documentation included drawings, work method statement, detailed design and the typical ICR.IAS JV quality documentation.
