On this page we explain how WRH analyses the regulations of MLC 2006 and exemptions as per STCW Manila Amendments, 2010:

The following 5 requirements apply, together:


minimum of 10 hours rest within any 24 hour period

2. these 10 hours of rest must not be devided into more than two periods
3. one of these two periods shall be at least 6 hours

the interval between two rest periods must not exceed 14 hours

(or from another perspective: a seafarer must not work longer than 14 hours without a rest period)

5. 77 hours rest within any 7 day period

according to MLC 2006, Standard A2.3 § 5 - 6


These regulations are not limited to one calendar day but apply over the date limit for two days as well.


10 hours rest within 24 hours



10 hours rest devided into no more than two periods


Duration of one rest period at least 6 hours


Interval between two rest periods ( = work period) min. 14 hours


77 hours rest in 7 days
