Empirical Design

Precisely evaluation of the reliability of aging structure is essential, particularly in the oil gas industry where inaccurate predictions of structural performance may have significant hazardous consequences. Related to this issue, it is important to predict the corrosion behavior of the gas pipeline structure used in the production of gas in subsea area. As corrosion is concerned, the effects of pipeline failure due to significant reduction of burst strength will make it hard for the pipeline operator to maintain the serviceability of pipelines. Therefore related to this problem, the resistance service of the pipeline is assessed by means of burst strength capacity. In this study, the critical part of the corrosion along 2.4 km pipeline is assessed using two approaches; empirical design codes formula and ANSYS numerical analysis. The future integrity of the pipeline is then assessed to predict the remaining year in service for the aging pipeline. The results and outcomes of the present study will be useful for evaluating the pipeline integrity as well as the prediction of the remaining life of in service aging pipeline structures.

Pipeline Failures

The integrity of pipelines transporting hydrocarbon is critical to economy, safety and environment. One of the leading cause of pipeline failures is 3rd party damage during excavation activities, followed by corrosion, which is becoming increasingly significant as the pipeline infrastructure ages. Current inspection techniques for corrosion monitoring may require the pipeline to be shutdown during inspection reducing overall availability and a potential loss of revenue. Structural Health Monitoring (SHM) offers the promise of a paradigm shift from schedule-driven maintenance to condition-based maintenance (CBM) of pipeline structures. Built-in sensor networks integrated with the pipeline can provide crucial information regarding the condition and damage state of the structure. Diagnostic information from sensor data can be used for prognosis of the health of the structure and facilitate informed decision processes with respect to inspection and repair, e.g., repair vs. no repair or replacement. Asset management can be performed based on the actual health and usage of structures, thereby minimizing in-service failures and maintenance costs, while maximizing reliability and readiness. This paper provides an overview on the design of a SHM system for in-situ real-time, rapid assessment of pipeline integrity using a built-in sensor network. Results of a cost-benefit study conducted for the system usage on pipeline structures will also be presented.
