📖
What is the Isp Hours Of Rest & How does it work?
The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) sets strict minimum rest periods to ensure crew fatigue does not compromise safety at sea. For watch‑keeping personnel the minimum rest is 10 hours in any 24‑hour period, 70 hours in any 7‑day period and 140 hours in any 14‑day period. Compliance is verified by comparing the actual hours worked against these thresholds. The calculation must consider the cumulative work time over the relevant windows (24 h, 7 days, 14 days) and subtract it from the total possible hours to obtain the rest earned.
R_{24}=24-W_{24}\text{h}
R_{24} = Rest hours available in the last 24 h window
If the derived rest hours fall below the STCW minima, the vessel must adjust watch schedules or provide compensatory rest to meet the regulatory requirements before the next sailing period.
