04192 Integrity Assessment of Pipeline Networks Through Close-Interval Potential Survey

Picture for 04192 Integrity Assessment of Pipeline Networks
Available for download

A close-interval potential (CIP) data survey on ~154 km of Crude Oil/Gas pipeline networks. This aim was to generate corrosion data to determine weak sections of the pipelines/flowlines and, to ascertain the effectiveness of the CP system and integrity of the Crude Oil/Gas pipeline networks. The pipeline networks were found safe for continued operation under its present condition.

This work involves a close-interval potential (CIP) data survey on approximately 154Km of Crude Oil/Gas pipeline networks. The CIP was carried out at 5-meter intervals along pipeline right of way (ROW) with a microprocessor controlled data collector (data logger) and a Cu/CuSO4 reference half-cell.

The survey runs from Makaraba, Utonana, Abiteye, Dibi, Olero Creek, Opuekeba, and terminating at the Escravos Tank Farm of the western swamp facilities. This study therefore seeks to generate corrosion data with a view to determining weak sections of the pipelines/flowlines. The CIP survey is also aimed at ascertaining the effectiveness of the CP system and integrity of the Crude Oil/Gas pipeline networks. The CIP values obtained were used to evaluate changes in structure potentials with respect to the environment, location/severity/population of "hot spots" (corroding areas), and potential areas of coating disbondment, holidays, blistering, seam tenting, cracking and wrinkling and location of areas that are subject to stray current electrolysis. Using all the CIP accumulated data; a risk assessment is presented to determine the present integrity of the pipeline networks. The assessment reveals that the pipeline networks were safe for continued operation under its present condition. Further, it recommends a repair/replacement program for some segments of the pipeline in order to bring the system to an acceptable level of operational safety and product availability. 

Key words: cathodic protection, close-interval potential, hot spots, risk assessment matrix

New cathodic protection (CP) criteria were developed based on AC and DC current densities measured using coupons. Using these criteria, the design of CP systems for newly constructed pipelines, paralleling high voltage AC power lines, and  DC rail transit systems, was successfully performed.

04044 Performance of High Potential Magnesium Anodes: Factors Affecting Efficiency

Magnesium anodes are provided to the corrosion control industry by a number of domestic and international manufacturers and distributors.  Anode composition is commonly the only criterion used for quality control by the end users. Many of the anodes, however, have been shown to meet the compositional and potential specifications, and yet have had measured efficiencies as low as 7%.
