Their mental health is affected by the environment in which they live, often coupled with long working hours that contribute to stress, anxiety, loneliness, depression, and suicide. This proposal seeks to improve the seafarers’ mental health by introducing a comprehensive, evidence-based global maritime mental health promotion program that attracts the youngest seafarers to choose and to stay in the job. Methods: The theories on empowerment, life-long- and problem-oriented learning with the inclusion of all stakeholders form the theoretical background. Our main task is to create responsibility among all stakeholders to help to create a comprehensive occupational- and public health program at sea that includes the whole maritime industry. The specific physical, chemical and psychological working environment factors on board also relate to the seafarer's health conditions (1)(2)(3). The quality of the mental work environment is dependent on several factors which have been carefully described in the past approx. 30 years (4) (5) (1). Ships with ongoing replacement of crew present great challenges for both the manager and the employees and the culture at the workplace (6). During navigation, the sailors are often moved to very small working groups, where conflict management can be difficult. The requirements are very variable, the nature of the work requires considerable discipline and thus less self-control. Support from superiors and colleagues can be made difficult by the fact that crews come from many different nationalities. These conditions can lead to experienced stress and burnout (7) (1). Fatigue is considered a significant health and safety problem [14]. Jet lag after long flights for joining is described as part of this (8). (12) In the latest research Helen Sampson, director of Cardiff University's Seafarers International Research Centre, said that seafarers working on cargo ships "experience very little happiness on board". (9) She said there was evidence recent-onset psychological disorders were increasing among serving seafarers but 55% of employers said they had not introduced any policies or practices to address mental health for a decade. Seafarers' mental health and well-being found that internet access would make the most significant contribution to improving mental health and well-being together with other key recommendations underscored in the report and the BBC News (Seafarers Mental Health and Well-being Nov. 2019). Jensen and Oldenburg conclude that because of many stressors on board, and the lacking respective education, there is a strong need to integrate stress management in the maritime educations especially for officers <sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> Guidelines for prevention <a rel="nofollow" class="external free" href="https://www.copsoq-network.org/assets/Uploads/COPSOQ-network-guidelines-an-questionnaire-COPSOQ-III-131119-signed.pdf">https://www.copsoq-network.org/assets/Uploads/COPSOQ-network-guidelines-an-questionnaire-COPSOQ-III-131119-signed.pdf</a> Authors "soft guidelines" page 7, start with: "Never start a psychosocial risk assessment unless there is a clear intention of taking action if indicated". The psychological stress in seafarers resulting from the Covid pandemic has already been investigated by our MAHRE group with GHQ 12 test.
