Pipeline Hydrocarbon Transportation: Some Operating Concerns and R&D Trends

This paper describes R and D efforts and trends and possible application of new technologies to improve on pipeline construction and operations. The paper also identifies possible solutions for some operating concerns related to pipeline integrity and safety. Safety is defined as protection for humans, the environment and materials/equipment. As in other industries, the oil and gas business too is driven by events; a typical example is the current interest on Stress Corrosion Cracking (SCC). Accordingly, there are technical concerns related to the influence of SCC and aging on pipeline integrity and the consequent financial concerns regarding possible pipeline upgrading, derating, abandonment and possible retrieval. Potential new solutions include a proposed flexible tube (currently under development) made out of fiber glass composites. This patented innovation could reduce pipeline construction and operating costs. This tube could also eliminate some problems typically associated with metal corrosion. Also included is the application of Fiber Optic Sensor (FOS) technology to the monitoring and evaluation of pipeline integrity. FOS technology may be utilized to study SCC because of its high resolution, and its insensitivity to electro-magnetic interference, and its real time availability.
