NL 255/21 | MCI - MLC Hours of Work and Rest Tool - updated for 2021

Φεβ 19, 2021

Refers to: Ship Owners / Managers / Operators of CI flagged vessels, PHRS Surveyors / Representatives     

Action Date: Immediate


To simplify the correct application of the MLC Regulation 2.3 – Hours of work and hours of rest – and to prevent non-conformities raised by external auditors or Port State Control, it is strongly recommended to employ the attached MLC Work Rest Tool which will allow you to monitor MLC hours of work and rest.


The Maritime Cook Islands highlight that in the application of the MLC standards, each vessel shall take into account the danger posed by the fatigued seafarers, especially those whose duties involve navigational safety and the safe and secure operation of the ship.


It is, therefore, in the common interest of all the parties involved, to ensure the limits fixed by the Regulation 2.3 of the MLC that are complied with.


The attached tool gives you the possibility to monitor the hours worked on board and will help to identify immediately any inability to comply with the MLC Regulation 2.3.


Guidelines for the use of the MLC Work Rest Tool

The file is password protected– ensuring the formulas and the layout of the tool that remain intact.

In the first sheet, you can fill the vessel and seaman details that automatically will be reported on all pages.


You have also a sheet “sample” as the guideline for filling.


The hours shall be indicated with the following letters:

“w” means working hours

“r” means rest hours

“n” means neutral hours (this letter shall be used in case of more than two rest periods in one day, in the application of the rule 2.3.6 “hours of rest may be divided into no more than two periods, one of which shall be at least six hours in length, and the interval between consecutive periods of rest shall not exceed 14 hours”).


The Work Rest Tool has been updated to reflect the year 2020 but you can start to use it from December 2021, to give continuity with the upcoming year.


Do not hesitate to contact us for more information you may need on the above.
