These costs are passed on, reflected in increased prices to the world's petroleum product consumers. With the advent of widely available computing and communications technology, it is logical that we should seek relief from corrosion and maintenance problems in the form of a high-tech solution. To this end the authors have developed an expert system, the Petroleum Corrosion and Coating Expert System (PCCES) equipped with an extensive knowledgebase of physical and chemical phenomena and the metallurgical characteristics of the pipes themselves. Essentially a complex decision tree, the expert considers factors in a real-world situation and attempts to produce appropriate conclusions based on inference from the knowledgebase. For greater ease of use, the expert system relies on a Java applet design, eliminating the need for proprietary client-side software.IntroductionThe deterioration of the components of gas and oil pipelines costs billions of dollars every year. It was estimated that in the United States alone the problem of corrosion cost 33 billion dollars in 1989 GNP. The application of control strategy for protection and coating of these pipelines would help the efforts to conserve natural resources1.Human experts in the field may give good advice on how control and protection strategies may be implemented, but human experts are not always available to the on-site maintenance personnel. Geographical and cost considerations make it impossible to provide live expert input at every turn. When, as is usually the case, the questions and tasks involved are of a repetitive nature (i.e. one case of pipeline maintenance bears much resemblance to another), there is a strong motivation for the design of an Expert system; a simple application of Artificial Intelligence able to analyze a situation based on real-world information and utilizes coded concrete information from human experts (knowledge) to infer appropriate actions and advise on-site personnel.The primary development goals for this expert system are as follows:Optimization of pipeline maintenance operations, thereby optimizing investments in Oil and Gas pipeline hardware and maintenance.Provision of a system suitable both for training and for direct application to everyday pipeline maintenance problems.Providing regular maintenance personnel instantly with the information needed to solve problems, which would normally require input from a human expert.Increasing the speed and reliability of solutions implemented in the field.Cost reduction through optimization.Assistance in the automation of uncomfortable and monotonous operations.Enabling wider access to technical knowledge within organizations.Design of the Expert SystemThe knowledge acquisition, representation and knowledgebase development for a pipeline corrosion and coating expert system begins with the acquisition of expert information, accomplished both by interview and review of published information. For the initial development we have seeded the system with knowledge from Dr. R. Islam, a noted authority in the field of petroleum engineering.As development continues, information from other experts and a wide ranging literature search will be integrated into the expert system's knowledgebase to provide it with an ever-widening area of expertise.
