Situation Awareness (SA) issues are often identified as contributing factors to drilling incidents, mostrecently in the Deepwater Horizon blowout. Two studies aimed to identify the cognitive componentsrequired for offshore drillers to develop and maintain SA whilst controlling subsea hydrocarbon wells. Instudy one, critical incident interviews were conducted with 18 experienced drilling personnel. Transcriptswere subjected to thematic analysis, producing a framework of cognitive processes that enable drillers tobuild up an understanding of what is happening in the well bore and surrounding environment, predictinghow the situation may develop. In the second study, analysis of 24 hours of observations (in-vivo andvideo) from a high fidelity well control simulator suggest behaviors such as monitoring and crew sharinginformation contribute to the drillers’ SA. The findings highlight the importance of SA for safe andeffective performance in drilling and are being used to develop a cognitive task analysis.
