Integrating Monitoring and Stress Management for Multidimensional Ship Safety Regulation and Seafarers' Well-Being Improvement

Abstract

The article deals with the problems of monitoring stress level in merchant seafarers using modern methods based on cortisol level measurement. The authors analyze the relationship between increased stress level and safety of navigation, highlighting cortisol as an important biomarker of stress. Data from studies conducted aboard two ships where the increase in cortisol levels in captains and their mates over a six-week period of employment was analyzed are presented. The results showed a significant increase in cortisol levels, indicating high stresses on the crew and potential risks to the safety of shipping. The paper proposes technological solutions for stress monitoring based on wearable biosensor devices that can be integrated into the crew management system for timely adjustment of working conditions and risk reduction. Special attention is paid to the interdisciplinary approach to stress management including psychophysiological, environmental and social factors
