The International Labor Convention came into force by the International Labor Organization (ILO) in 2013, and the "Maritime Labor Convention, 2006" (MLC,2006)(1) also came into force. As a result, the law on seafarers' labor was also amended. In this study, authors focused on fatigue caused by labor of seafarers and conducted a survey on fatigue trends due to differences in working environments with the aim of improving the working environment. First, in order to investigate fatigue caused by difference in work that behavior over time, a fatigue checklist was used at the onshore labor organization, and heart rate was measured.In this paper, fatigue of seafarer's were investigated and the main conclusions obtained by this research are as follows:(1)Fatigue can be investigated by a fatigue checklist and heart rate measurement. Also, fatigue recovery can be investigated by sleep measurement and through a questionnaire regarding waking up sleepy.(2)Working onboard tends to be more fatiguing than working onshore.(3)Sleep is related to both fatigue and fatigue recovery; fatigue recovery effect is low while working onboard; quality of sleep is related to one’s living environment and the ship’s operating condition.
