Allocation of Performance Shaping Factors in the Incident Analisys: A Case Study in a Midstream Installation

In the midstream sector, had occured many major accidents involving fuel storage terminals and pipelines, which had significant consequences such as fatalities, injuries, health problems due to explosions, fires, toxic vapor cloud, significant environmental damage, damage to economy, loss of inventory, reconstruction costs, discontinuity of production, legal costs, damage compensation costs, increased risk in the insurance premium and damage to image of the companies involved to the accident. The efficient and safe storage and distribution of oil presents challenges for technical solutions, remaining essential for economic activity. In this context, it is necessary identifying performance shaping factors (PSFs) that influence safe operations. The most typical root causes related to accidents include equipment failure, human error, environmental factors, work organization, training and, communication, among others. The principal objective of this study is to apply a methodological framework to identify the factors that affect the performance of workers in a terminal unit for oil storage and transportation. After identification of factors that affect the job performance, a decision-making model based on AHP (analytic hierarchy process) is applied to rank and weight the principal performance shaping factors (PSFs) that influence safe operations. The next step involves the use of the SHELLO model to group the main PSFs in elements named software, hardware, environment, liveware and organization. In the last phase, a relevant accident that had occurred in refered site was analyzed.
