Seafarers’ work in vessels at sea is one of the hardest, most demanding and under very difficult conditions profession. Seafarers often work for very long hours, far from their relatives, isolated in a multicultural, highly hierarchised micro-society. Studies have also shown that bullying is an often phenomenon in ships. This situation often generates mental health problems, which put at risks lives, the vessel, passengers, cargo, the environment from pollution and local coastal economies. The central aim of this project is to develop a training course and learning resources for seafarers and maritime workers concerning the preservation and improvement of their mental health.
