Maritime & Shipping · Ireland
Seafarers stand watch systems such as six-on/six-off for weeks at a time, with broken sleep, noise and motion. Fatigue on watch raises the risk of grounding, collision and injury.
Reg Watch
Regulatory change that affects how you manage fatigue in maritime & shipping: what has changed in the last 12 months, and what is on the way.
Upcoming changeNo date set yet
Amendments to the Maritime Labour Convention agreed in 2025 (harassment and bullying, shore leave, repatriation, medical care) are expected to take effect internationally in December 2027. The ILO has called for joint work with the IMO on seafarer hours of work and rest; no new rest-hour rule has been proposed.
Regulatory changes checked as at 1 October 2026.
Regulation
Seafarers are carved out of the general national working-hours rules and covered by international standards given effect through Irish law. Those require at least 10 hours' rest in every 24 and at least 77 hours' rest in every 7 days, structured differently from the shore-based regime - the daily floor is lower, the weekly total higher, and rest may be split into no more than two blocks. Compliance is verified by flag state survey and certification, and port state inspectors check the same records wherever the ship trades.
DoTLogos identify the regulator and don’t imply endorsement.
Seafarers on Irish-flagged ships sit outside the general national working-hours rules, under international maritime rest-hour standards instead. The Marine Survey Office, part of the Department of Transport, is the flag state authority that surveys and certifies Irish ships and inspects rest-hour records. Since January 2026 marine accidents are investigated by the new Marine Accident Investigation Unit.
Seafarers on Irish-flagged ships must get at least 10 hours' rest in any 24-hour period, split into no more than two blocks with one of at least 6 hours and no more than 14 hours between consecutive rest periods, and at least 77 hours' rest in any 7 days - put the other way, no more than 14 hours' work in 24 and 72 in a week. Ship operators must keep records of each seafarer's daily hours of rest, make them available for inspection, and hold the maritime labour certification confirming compliance, checked by government surveyors. Shore-based port and terminal staff stay on the ordinary national rules.
If an Irish ship doesn't meet these rest-hour rules, the government can detain the vessel - meaning it simply can't sail - and can withdraw its compliance certificate, both immediately and severely costly for a shipping company. This can also be checked by foreign port authorities when an Irish ship visits another country, so getting it wrong carries international, not just domestic, consequences.
The enforcement lever here is the ship, not a euro tariff. A vessel can be detained until it complies and its maritime labour certificate withheld or withdrawn, and the same rest-hour records are checked by port state inspectors abroad. Lost trading days, charter-party penalties and cargo-delay claims from a single detention typically dwarf the fines seen in general safety cases - which in Ireland run to €5,000 summarily and €3,000,000 on indictment.

Fatigue-critical roles
The roles where a fatigued worker is most likely to cause serious harm, the tasks that carry the risk, and why fatigue builds up in them.
| Role | Risk | High-risk tasks | Why fatigue builds |
|---|---|---|---|
Officer in charge of a navigational watchRules
| Critical risk | Keeping a bridge watch alone in the 00:00-04:00 or 04:00-08:00 watch; collision avoidance in coastal traffic; port arrival straight after cargo work | 6-on/6-off or 4-on/8-off watches, port-call cargo work eating rest, time-zone changes, months-long tours |
Engineer officerRules
| Critical risk | Unmanned machinery space on-call alarm response at night; engine-room watch; bunkering, fuel changeover and blackout recovery after broken sleep | UMS on-call nights with repeated alarms, port maintenance during rest periods, heat and noise |
Marine pilot (port company)Rules
| Critical risk | Conning large ships through pilotage waters at night; boarding by pilot ladder in swell; back-to-back jobs and long coastal pilotages | 24/7 on-call job lists, night jobs, long transits and travel between jobs, irregular rest |
Tug masterRules
| Critical risk | Ship-assist and harbour towage at night on short notice; towline handling near girting risk; coastal barge towing on two-watch systems | On-call 24 h harbour rosters, two-watch towing (6-on/6-off), back-to-back jobs |
Skipper (fishing vessel); master (passenger boat)Rules
| Critical risk | Skippering a ferry or workboat with minimum crew on long days; night fishing then steaming home after hauling; lone watch on small vessels | Long seasonal days, early starts, split shifts on commuter ferries, multi-day trips with fragmented sleep |
Able seafarer (watch rating)Rules
| High risk | Lookout and helm on night watches; mooring and anchor work during port calls that cut into rest; fire rounds | Watch rotations, port-call work in rest periods, long tours |

How the suite fits
Grades describe how strongly a product connects to an obligation. None discharges an obligation, and none carries a compliance warranty.
Regulation 6(1) of S.I. 314/2023 requires your watchkeeping to have regard to STCW Code section A-VIII, under which watches must be rested and fit for duty. Fatiguefit4Duty supports that. A fitness-for-duty check, not a fitness-for-duty decision - the duty call stays with you.
About Fatiguefit4DutyNo Irish maritime rule names a fatigue assessment after a casualty or near miss. Was It Fatigue? supports your own investigation of incidents involving your seafarers and your safety management review. A structured judgement aid, not a determination of cause.
About Was It Fatigue?No Irish maritime rule reaches sleep in new-parent households. SleepWellBaby is offered to the working parents among your seafarers as a wellbeing benefit, not as a step any Irish regulation requires.
About SleepWellBabyRecommended bundle
Every bundle is priced on prevalence: your whole cohort gets access, and you pay for the share predicted to need each product. How pricing works.
Proactive fatigue risk: assess, manage and train, with sleep screening underneath.
Assess, manage, investigate: from the Census to the point of duty to the post-incident review.
Why this pairing in Ireland
S.I. 314/2023 reg 6(1) applies STCW A-VIII: watchkeepers must be rested and fit; Fatiguefit4Duty supports that with a pre-watch check. Awareness eLearning refreshes the STCW fatigue competence; Sleepfit screens between medicals. Fatigue Lifecycle adds casualty review.
