Sammendrag
Human error is a contributing factor towards almost all major accidents involving Dynamic Positioning (DP) systems. The expectations of the DP operators’ performance are high. Their jobs are said to entail roughly 99% boredom and 1% action, where their main task is to monitor the computer screens, and they need to be ready and able to recover the position of the vessel within seconds of an emergency. The DP operator is the last barrier for avoiding collisions with potentially major consequences. The aim of this presentation is to advance an understanding of the DP operators’ performance situation, presents how to develop principles for the visualization of risk information, and illustrates how this can improve detection of hazardous situations and decision-making processes for DP operators. User-centered design is critical for the development of the principles for the visualization of risk information. User-centered design emphasizes the gathering of information on the user context and user needs. Methods for gathering this information include interviews and observations. The focus of the presentation is on human machine interface, risk communication, the visualization of risk, and how this can improve decision-making for DP operators. Furthermore, the presentation concludes with possible other applications of the principles for visualization of risk for DP operations, and the need for further research.
