The document summarizes key findings from a three-year study called MARTHA on long-term seafarer fatigue. The study found that masters suffered more fatigue than crews, fatigue can cause long-term health issues, and motivation decreases over long voyages. It also found that sleep quality deteriorates and social cohesion starts to suffer after six months at sea. The study collected extensive data on fatigue, sleep, and well-being from over 1,000 seafarers. It provides guidance to help shipping companies improve practices around fatigue. Wallem Ship Management supports the findings and discusses its programs to promote seafarer wellness and mitigate fatigue risks.
