Health & Safety
Newly-developed cathodic protection systems using autonomous, networked sensors deliver information about the pipe-to-soil electrical potential at any desired location on a pipeline, leading to closed-loop CP-current regulation for optimal protection of the pipe. Such a system is also sensitive to any physical contact to the pipeline and therefore offers additional surveillance functionality. Inside the pipeline, in-line inspection with magnetic flux leakage (MFL) and electromagnetic acoustic transducer (EMAT) technologies offers more detailed information about the internal and external problems associated with corrosion, cracking and disbondment of the external coating. Leak detection can also be carried out by means of an in-line inspection tool carrying sensors for detecting leakage noise. For the purpose of protection against third
party interference, in-line inspection technology is also used for detecting metal loss or undesired metal-enhancement, which may related to illegal intervention on the pipeline. All the above technologies are independent of each other, but they are all trying to expose any weakness of the pipeline from different facets.
When all these different technologies are integrated on a single software platform, enhanced system intelligence for risk assessment is obtained. Tis enhanced intelligence can then be used to identify actual and potential adverse events, to suggest effective and comprehensive means for the reducing of risk, or to plan useful maintenance activities in advance. It can even indicate the need for future technology developments. Improving the effectiveness of the pipeline integrity platform by adding new technologies is a never-ending process. Te ROSEN Group has already supplied
the market with one of the most powerful software platforms available for pipeline integrity management, and is actively developing various real-time monitoring solutions. In addition, the company is constantly improving
the reliability and effectiveness of its ILI services. In order to enhance risk assessment capability, ROSEN is also aiding pipeline surveillance technologies by focusing on existing leak detection solutions based on ILI techniques, which are specially designed for convenient and low-cost frequent running by a pipeline operator. ●
