The capabilites of the Topcorp model were evaluated by testing it in Bongkot field conditons. Field data from 10 pipelines subject to top of line corrosion and inspected at least twice were used. The pqper summarises the results and discuss the cabailites of Topcorp to predict TLC and cols spot corrosion
