Human error plays a significant role in oil and gas pipeline systems’ incidents and accidents. According to one study, operator error was the "direct cause" and was responsible for 30.9% of 500 incidents involving pipework failure and subsequent chemical release. The material presented in this paper is based on findings of an investigation of control room operations of a U.S.- based oil and gas pipeline company. Notwithstanding, the utilized framework and its findings could be applied to the control rooms of other pipeline systems. Both the micro- and macroergonomic considerations are discussed; suggestions for the reduction of potential for human error through the elimination of human-task and human-machine mismatches are offered.
