Probabilistic failure analysis of underground flexible pipes
Methods for estimating structural reliability using probability ideas are well established. When the residual ultimate strength of a buried pipeline is exceeded the limit, breakage becomes imminent and the overall reliability of the pipe distribution network is reduced. This paper is concerned with estimating structural failure of underground flexible pipes due to corrosion induced excessive de...
متن کاملComputer Vision Techniques for Automatic Structural Assessment of Underground Pipes
Pipeline surface defects such as cracks cause major problems for asset managers, particularly when the pipe is buried under the ground. The manual inspection of surface defects in the underground pipes has a number of drawbacks, including subjectivity, varying standards, and high costs. An automatic inspection system using image processing and artificial intelligence techniques can overcome man...
متن کاملFull-signature real-time corrosion detection of underground casing pipes
Corrosion monitoring and early detection of pits and wall thinning for casing pipes are considerably important to gas and petroleum industries since the frequently occurring corrosion at the internal or external parts of those steel casing pipes used in underground gas storage or oil fields causes production and environmental protection problems. In this paper, a new version of the direct curre...
متن کاملAutonomous Modeling of Pipes within Point Clouds
Three-dimensional models are in increasing demand for design, maintenance, operations and construction project management. Point-clouds are the main output of automatic data collection using laser-scanners and photogrammetric technologies. Pipe-works may comprise 50% of the value of important construction projects such as industrial and research facilities. We have developed a practical and cos...
متن کاملDEVELOPMENT OF PRODUCTIVITY MEASUREMENT AND ANALYSIS FRAMEWORK FOR MANUFACTURING COMPANIES
The purpose of this research is to present an alternative approach for measuring productivity in manufacturing companies. To achieve the research objective, an in depth investigation on the existing productivity measurement and analysis practices of a case manufacturing company has been carried out through both qualitative and quantitative approaches. The investigation result has shown that the...
