Providing a model for inspection, repair and maintenance of oil and gas transmission pipes – A Literature Review Study

Providing a model for inspection, repair and maintenance of oil and gas transmission pipes to marine platforms is among the most important issues related to marine structures, especially in relation to piping at the bottom of the sea [1 and 2]. In this way, it is quite effective to recognize different defects caused in the piping sections of offshore industries for their repair and maintenance as well as for suitable positioning of the pipes in deep water to prevent the defects [3, 4, 5 and 6]. These defects may be caused by scour of waves, effects of waves, leakage, rupture and corrosion. This project deals with corrosion. Moreover, use and recognition of different tests and procedures will be of a great importance to detect the defects. After detection of defects by using the existing procedures, different processes of pipe repair and maintenance should be used to improve the condition of pipes. In this regard, several models and procedures have been provided to achieve this purpose. In this project, some of the different types of breakage and failure caused by corrosion in oil and gas transmission pipes are identified and predicted and the results have been validated by authentic research bodies and laboratory tests.
