...Abstract In 2015, the National Transportation Safety Board conducted a study ¹ , revealing that while Pipeline and Hazardous Materials Safety Administration (PHMSA) gas integrity management measures effectively address corrosion and material failures in pipes and welds...

... and testing conducted in order to outline the methods followed by major oil producer in order to extend the life of RTR pipes. This includes, joint integrity assessment, pipes integrity assessment, regression analysis, and a network health check. This method was tested in order to confirms the integrity...

... of asset integrity management, is applied in a reactive fashion. The process of failure analysis is easy to understand intuitively, however, underneath that intuitive understanding are important conceptual principles, which are commonly either misunderstood or not considered at all. As a result, failure...

... than 100 homes and cost $2.8 billion. An investigation by the National Transportation Safety Board (NTSB) found that PG&E had a faulty integrity management (IM) system that failed to detect a defective section of the pipeline resulting in the devastating explosion. The PG&E incident spurred...

..., likely around the time of manufacturing or installation. Abstract Pipeline defects are routinely found in the oil and gas industry. Most often they are minor, and do not affect the integrity and safety of the pipeline. However, in some cases, identifying and repairing critical defects is mandated...

..., and an anchor for a floater. The two teams involved are the structures team and the subsea integrity team. Depending on the company, the subsea integrity team may be responsible for the entire system or for only the part that is subsea. This can lead to a question of which team assesses the chain, as it is both...
