Oil product transport pipelines are subject to failure processes, their technical accidents leading to environmental pollution, affecting human activities and especially high financial losses. That is precisely why conducting an audit regarding the condition of the pipeline is recommended by the legislation in force. The purpose of the article is to present the defects that may appear during the operation period of the pipelines transporting petroleum products and to establish a way of determining the risk in operation based on the use of numerical models created for this purpose. Also presented are the maintenance models of the main oil product transport pipelines and the history of the application of the risk assessment models in the operation of these transport systems. The model proposed in this article is based on the use of all the elements that can intervene in affecting the transportation systems of petroleum products, being the only evaluation system that uses neural networks, both in the definition of risk and especially in the establishment of pipeline rehabilitation methods.

The transportation infrastructure for petroleum products contains complex pipeline systems, developed on a global scale and totaling investments of hundreds of millions of dollars. The operation and maintenance of these systems have to be performed in relation to the analysis of incidents of various types, which take place in various areas of the world. The present paper aims to analyze in as much detail as possible, from a statistical point of view, the case of the pipeline system for petroleum products in Romania in order to streamline the operation of this critical infrastructure for Romania. Through the statistical tools, we established the hierarchies of the causes of the analyzed incidents, weights of the effects generated by these sources of accidents, and correlations between various parameters, in order to create a useful plan of measures and actions in the efficient operation of the pipeline system. The importance and topicality of the subject is also demonstrated by the major negative impact of the accidents in this sector, through product leaks from pipes in the soil and in watercourses, which generate significant pollution values, thus influencing the balance of the environment.

“…According to [15], the total direct economic losses from accidents on US gas pipelines for the period 1986-2012 years amounted to $558,778 million. According to [16], the average damage from accidents at gas and oil pipelines is $10 4 -$10 7 , excluding the cost of gas losses. The actual gas losses reach 10 4 m 3 .…”

“…In reality, the defects have inevitable random dispersion of sizes. For detected defects, these are caused by the random nature of the defects, as well as by statistical errors and the probabilistic nature of the operational characteristics (sensitivity and detectability) of non-destructive testing methods [16]. The dispersion of the calculate sizes of defects determined by statistical scattering loads, operating conditions and scattering of mechanical properties.…”

Subsea inter-field pipelines are an important element of offshore oil and gas infrastructure. Leakage or fracture of these pipelines is associated with the risk of large economic and environmental losses. One of the main sources of pipeline fracture is pipe defects. The presented section discusses the methodological aspects of assessing the hazard of defects of subsea inter-field pipelines by risk criteria of accidents. A conceptual approach of defects hazard assessing by risk criteria has been formulated, based on analysis the requirement of modern standards. The risk is defined as the probability of negative consequences, the scale of which is determined by the hazard class of pipeline accidents. The probability and scale of accidents are linked by a risk matrix. A method for a three-level assessment of the suitability of a pipeline for operation after in-line inspection has been developed. The method allows assessing the hazard of the most typical defects in subsea pipelines, such as metal loss, metal delamination, cracks and crack-like defects. The allowable defect sizes are determined for the given risk criteria using partial safety factors. The novelty of the methodology lies in the substantiation of safety factors according to risk criteria corresponding to a given class of damage and loss. A scheme for making decisions on the admissibility of defects by risk criteria has been developed. An example of hazard assessment of defects in subsea pipelines is presented.
