Abstract
During recent years, many systems and models have been developed for inspecting, monitoring and managing the maintenance of oil/gas pipelines. However, the adoption and application of these systems by the industry have not been very effective. On the other hand, the reliability of some condition assessment systems is not very efficient because of: (1) the subjective nature of monitoring data interpretation by experts; and (2) the complex relationships between the many types of defects. Dawotola et al. (2013) developed an integrity maintenance optimization framework for petroleum pipelines for the determination of the probability of failures and their associated consequences. Hovhanessian et al. (2008) developed pipeline risk management system for lifetime prediction and to establish priorities for monitoring activities. Otegui (2014) investigated the conditions contributed to failures of buried pipelines. The study concluded that the most frequent threats for the integrity of onshore buried pipelines are corrosion and third party damage, as well as loss of data about material and operation, old repairs and demographic changes. Due to the constraints of time, budget and other resources such as manpower and equipment, it is not possible for oil and gas assets owner organizations to either attend to all maintenance requirement schemes within a given planning period or to perform all the planned maintenance concurrently. Accordingly, the primary objectives of this research is to investigate and rank the significant parameters governing the decision making process for priority rating of repair and maintenance activities for oil/gas pipelines and to develop an integrated pipeline maintenance management system.
