Abstract Introduction The aim of this study was to screen for MSD complaints, to analyze the activity and to identify their risk factors. Methods This cross-sectional study involved 903 men aged 20 years and with a seniority 2 years. It included a questionnaire and an ergonomic analysis of the activity. The questionnaire included: socio-demographic and professional characteristics, health status and life habits, stress and items from the Nordic questionnaire. The observation of work situations required video recordings and the use of three methods Occupational Safety and Health Administration (OSHA), Rapid Upper Limb Assessment (RULA) and Gesture Tracking and Assessment Tool (OREGE). Results The prevalence of MSDs was 61.9%. It was significantly higher among deckhands than among other professionals (65.6% versus 27.4%; p 0.001) and among seasonal workers than among permanent workers (67.8% versus 43.1%; p 0.001). Stress was an aggravating factor, whereas leisure activities were protective. The prevalence of MSDs was 40.5% (lower back), 40.4% (wrist/hand joints), 34.6% (neck) and 31.7% (shoulders). The ergonomic analysis of the workstation was performed on a deckhand who unloaded the fish crates out of the hold of a trawler. OSHA score = 12 (normal5); significant risk of upper limb MSD. RULA total score = 7 (acceptable between 1 and 2); immediate modification. OREGE scores evaluating effort, repetitiveness and joint positions indicate that the actions were not recommended or to be avoided. Conclusion The analysis made it possible to evaluate the difficulty of the job and to note a high risk of MSDs requiring ergonomic and organizational improvements.
