on Towing Vessel Crew Fatalities

Report of the QAT. The Quality Action Team (QAT) on Towing Vessel Crew Fatalities was chartered in November 1995 as the first subject-specific QAT to be established under the auspices of the Coast Guard-AWO Safety Partnership.

Fatigue of a watchstander is often cited as a possible cause of an accident. NASA has done extension research into fatigue and how it effects individuals, and should be considered whenever an accident occurs.

This site has a wealth of information from the NASA Ames Research Center on Fatigue Countermeasures. The goals were to determine the extent of fatigue, sleep loss and circadian disruption in flight operations; to determine the impact of these factors on flight crew performance; to develop and evaluate countermeasures to mitigate the adverse effects of these factors and maximize flight crew performance and alertness
