Online Leak Sealing Using Modified Composite Repair to Stop Minor Leaking on Piping

In general, the composite repair only effective as leak sealing if the system shut down (offline condition). Composite repair for leak event required sufficient curing time without any pressure presence to get best performance, If the curing time is not reached, the optimum bonding of the composite material with the pipe surface will not achieved so it will tend to leak again. Meanwhile, for critical lines may trigger total shutdown for entire field. Asset integrity engineering team seek the solution to close the leak as quickly as possible, safe, relatively cheap and without any shut down platform. Composite repair was chosen with some modification by fabrication venting pad as patched material on pipe leak surface. This venting nipple pad will localize the leak and relocate the hydrocarbon release to a safe area using temporary hose waiting composite curing time achieved. This repair was executing with very minor preparation and without any welding or hot work activities. Repair was done without any safety issue, no shutdown and all activities categorizes as cold work.
