The report describes an exploratory first phase of an investigation of human stress and fatigue in the merchant marine. Its principal purposes were to: survey the effects of fatigue on human performance in the transportation industries; describe the state of the art in measuring fatigue; investigate the causes of stress and fatigue on merchant ships; summarize the insights gained about the implications of reduced manning as well as measures to mitigate fatigue; and discuss the results of preliminary attempts to gauge fatigue during the routing voyages using survey methods. The findings in the report are based primarily upon about three dozen extended interviews conducted with officers on five merchant vessels during brief coastal voyages. The physiological and behavioral methods of fatigue measurement reviewed were found to be difficult to apply during routine operations, but the self-reporting survey techniques tested eventually proved quite workable. It was concluded that organization and design factors could provide opportunities under some circumstances for the design and operation of advanced merchant ships which can be sailed safely and efficiently by well-rested crews which are smaller than are common today.
