The purpose of this master’s thesis was to investigate the risks associated with performing a vigilance task in a simulated moving environment. More specifically, the effects of simulated motion on both postural stability and the performance of a simulated search and rescue (SAR) task. Many offshore occupations are considered strenuous and potentially dangerous in nature due to continuous wave-induced perturbations. These perturbations are responsible for accidents and injuries related to reduced postural stability and increased work-related energy demands. To investigate these potential adverse effects, a single data collection utilized a motion platform and a 360-degree screen which displayed visuals synchronized to platform motions. The results show that performing a SAR task in a simulated moving environment has a significant adverse effect on SAR task performance and postural response. As simulated wave motions increased, there was a decrease in SAR task performance and increased lower limb muscle activations, as well as the number of steps taken. These results indicate the likelihood of increased risk of falls and human factors errors when performing a simulated SAR task in a motion environment.
