Human Performance is a different lens through which to view safe work execution. Human Performance principles provide a framework to consider and account for the way work actually gets completed. By understanding how work gets done we can make it easier to get it right and harder to get it wrong. Human Performance recognizes the complex interaction between workers, the systems they use, the processes they follow, the equipment they interact with and the culture inside of which they work. This presentation will focus on the application of Human Performance concepts from early engineering and design, construction execution, completions, through handover to normal operations and maintenance. It will provide a brief overview of what Human Performance is including key messages around the role of leadership, the concepts of latent conditions, drift, error traps and performance modes. The remainder of the presentation will provide examples of how to successfully integrate Human Performance thinking into deepwater projects from the early design phase through execution and into normal operations.
