Practical Compliance / Role of Shore Management

Management of Watch Keeping & Working Routines

Generally, the three-watch system such as 4 on / 8 off, provides an optimal approach although non-conformances will be triggered by periods of additional work if they are not properly planned and managed.

A two-watch system, such as 6 on / 6 off, will provide short-term compliance although technical non-conformances will occur during each rest period under both the STCW and MLC Conventions. In addition, any period of additional work will result in significant non-conformances during subsequent work periods.

If necessary, Master may implement 5 on/7 off watch schedule to provide enough rest to the crew and meet the minimum rest hours regulations.

Day workers are generally viewed as being relatively straightforward when managing their work/rest periods. However, callouts and the response to alarms will impact on their ability to comply with minimum rest period requirements. Good planning and, where necessary, the adoption of compensatory rest periods will serve to limit the number of recorded non-conformances.

Crew should be given holiday on Sundays as much as practically possible.

On vessels with an additional deck officer for watchkeeping and where the Chief Officer is primarily on day work, the Master shall ensure that minimum 4 navigational watches per month are assigned to the Chief Officer to maintain his navigational skills.

Drills and training, fire rounds, and attending to UMS alarms are to be recorded as work.

According to IMO and OCIMF guidelines, musters, firefighting and lifeboat drills, and drills prescribed by national laws and regulations and by international instruments shall be conducted in a manner that minimizes the disturbance of rest periods and does not induce fatigue.

A short break is by definition considered as neither work nor rest. The definition of how long a short break is varies from Flag State to Flag State. When calculating rest, these break periods are ignored and not counted as rest. Software allows the user (vessel) to select their Flag’s interpretation of short breaks if one of the following:

For Company managed vessels, any break of 60 mins or less (0-60 mins) shall be excluded from the rest period.

Experience has shown that the levels of non-conformance on a vessel can be significantly reduced by enhanced awareness and management on board.

Over-reliance should never be placed on one individual, risking adverse impact on normal rest period requirements.

Role of Shore Management

Company provides proper guidance on the management of fatigue, its impact on safety, and the regulation of hours of work/rest.

Seafarers must alert their onboard managers should they be working, or at risk of working, in non-conformance or violations of the minimum requirements.

Masters are required to inform Crew Manager/respective MTSI immediately in case of:

In the event of significant non-conformance, the Master is authorized to take action which may include the suspension of operations until personnel are suitably rested. Prior to that decision, the Master should have raised the issues and sought guidance from the marine department.

AA) Shore Management Actions: Shore management should also be aware of, and react to, planned or expected periods of high intensity operations and ensure that staffing on board is adequate in good time prior to the planned operations.

Operations should include, but not be limited to:

BB) Monthly Monitoring by Shore Management (MTSI): Shore Management (MTSI) should ensure the following is done every month to ensure proper monitoring of work and rest hours:

CC) Monitoring and Evaluation: MTSI to monitor and evaluate rest hours received from the vessel once every 7 days and conduct a review and analysis in cooperation with TSI. Any major concerns to be raised to Senior Management by the Marine Manager.

Respond to NC raised by the vessel on breaches of hours of rest – Each NC to be evaluated and responded to accordingly.

Escalation to Marine Manager: The following should be escalated to the Marine Manager:

7. ADDITIONAL CREW

Master shall request for additional crew if the Vessel is unable to meet minimum rest hours as per the various regulations due to:

The Master shall send the request to MTSI with a copy to Crewing Operations.

8. SHORT-HAND MANNING

The Master shall re-schedule the working hours in the case of short-hand manning onboard due to some urgency until the manning levels are back to normal.

9. SOFTWARE

The Master shall use ISF Watch Keeper or similar DSM software to record the work and rest hours.
