Administrative burdens and over-exertion in Swedish short sea shipping

ABSTRACT

Despite significant changes in work tasks performed on board, towards more sedentary monitoring and administrative work, the incidence of occupational injuries and disorders remains high among seafarers. In order to improve safety standards, industry stakeholders increasingly require written documentation of numerous routines, procedures and tasks performed on board. These increased demands have however added to the administrative burden. Some say, to the extent that administrative work has become a safety risk in itself. This paper presents the result of a survey investigating how Swedish seafarers perceive their own level of fatigue, stress and over-exertion related to work. The material consists of 1309 respondents originating from a random selection procedure, of which 651 reported to be employed in short sea shipping. Multiple regression analysis (OLS regression), allowing adjusted effects, were applied in several steps of the analysis. The highest levels of exertion were reported by employees in the catering department, positions not generally associated with high administrative burden. Perceived high levels of administrative work do increase the level of exertion, but cannot explain the observed pattern. Future ship and trade-specific studies on physical and mental well-being and complementary studies on the catering department’s working conditions and work environment are necessary.
