Short sea shipping poses significant problems for many seafarers,
particularly for officers employed in oil tankers as chief officers.
This study examines chief officers’ working conditions on short sea
shipping. In this study, Simio simulation software was utilised to
evaluate the working hours of chief officers. The results demonstrate
that the rest periods of the chief officers have been less compromised
as the navigation period increases in oil tankers operated on short sea
shipping. To comply with the relevant regulations, a navigation period
of 24–28 h is the minimum condition for an oil tanker to have a chief
officer; however, an additional officer may be required for shorter
voyages. The findings of the research provide some recommendations to
maritime authorities to achieve safe short sea shipping.
