In order to optimize the maintenance of plants, such as chemical or petrochemical one, concentration of resource on effective parts is important and one candidate for this is the introduction of risk based inspection (RBI) . However, one of the subjects for the introduction of RBI in my country is a development of damage database. Risk assessment is done by multiplying consequence with probability of failure (PoF) and thus the PoF data play an important role. If we have no database concerning PoF, other databases such as those of reference or oversea countries have to be referred. In this case, those data might not be suitable to Japanese situation. Therefore, development of Japanese own database is quite important. This paper deals with the failure of pipes and shows some points concerning how to develop the PoF database.
