• Abstract:
  This 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 this report are based primarily upon about three dozen extended interviews
  
  conducted with officers on five merchant vessels during brief coastal voyages. In the
  
  course of these interviews, more than a score of variables were identified which affect
  
  fatigue and stress, which may be grouped into organizational factors, voyage and schedul
  
  ing factors, ship-design factors, and physical/environmental factors. These interact in
  
  complex fashion resulting in widely different levels of fatigue on different ships and in
  
  different situations.
  
  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.
