Description
Summary:To obtain information on stress, fatigue, and work-rest cycles of both submersible operators and surface support crew members during an actual submarine rescue fly-away mission, six operators and seven surface support personnel (SSP) were monitored during the conduct of a six day trial open-sea submarine rescue evolution using the Deep Submergence Rescue Vehicle (DSRV), Mystic. Operators and crew members lived aboard the mother submarine which carried the DSRV from port to the site of the downed submarine and return. Demographic information, psychological measures, performance measures and environmental data were obtained during pre-deployment, transit-out, at dive site, and transit-in periods. The overall results suggested that a DSRV mission of the present duration and difficulty can be accomplished without exceeding the capabilities of the crew and support personnel. The trend of the changes does, however, suggest that missions of longer duration may require scheduling of regular sleep periods for personnel to maintain performance. (Author)
