Maritime & Shipping · Singapore
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 changeExpected from 23 December 2027
Maritime Labour Convention amendments adopted 6 Jun 2025 (shore leave, repatriation costs, a legal ban on onboard harassment) are expected in force 23 Dec 2027. The Workplace Fairness Act 2025 (covering disability and mental health conditions) is targeted to commence around end-2027.
Regulatory changes checked as at 1 October 2026.
Regulation
Maritime has binding fatigue rules. Seafarers on Singapore-registered ships must have at least 10 hours' rest in any 24 hours and 77 hours in any seven days, in no more than two periods, one of at least six hours, with no more than 14 hours between rest periods. The master keeps daily rest records. Seafarers are outside the Employment Act; port, shipyard and other shore staff follow the baseline.
MPALogos identify the regulator and don’t imply endorsement.
The Maritime and Port Authority of Singapore (MPA) enforces seafarers' hours of rest on Singapore-registered ships under the Merchant Shipping (Maritime Labour Convention) Act 2014 and the STCW Convention, including through inspection and detention. The Transport Safety Investigation Bureau investigates marine casualties. Shore-based staff fall under MOM.
As shipowner you must ensure your seafarers get the minimum hours of rest - 10 in any 24 hours and 77 in any seven days - with the master recording rest daily in the standard format and giving seafarers a monthly copy. Your manning and safety management arrangements must make those hours achievable in practice, including after crew changes. Shore-based port and shipyard workers are covered by the baseline safety and employment law.
A shipowner who fails to provide minimum rest commits an offence punishable by a fine of up to S$10,000 (Merchant Shipping (MLC) Act 2014, in force 2026). MPA can detain a non-compliant ship until deficiencies are fixed, and sailing in breach of a detention notice carries up to S$50,000 and/or two years' jail for owner and master. TSIB publishes its fatigue findings in named reports.
Fines are modest - up to S$10,000 per rest-hours offence (2026) - but detention stops a ship earning. A fatigue finding in a published TSIB report, as in the Hafnia Nile collision, carries reputational and charter consequences well beyond any fine.

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 watch (deck officer)Rules
| 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 |
Marine 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 |
Harbour pilot (PSA Marine)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 master (harbour craft)Rules
| 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 |
Harbour craft / ferry masterRules
| 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 seaman (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 |
Stories
Published findings and prosecutions from regulators, courts and investigators in Singapore.
Jul 2024 · At sea, South China Sea
In 2024 a Singapore-registered tanker collided with another tanker in the South China Sea; both ships caught fire and a shore worker on the other tanker later died. Singapore's Transport Safety Investigation Bureau found the officer of the watch had under two hours' unbroken rest in the 38.5 hours before his midnight watch and was likely fatigued. He had joined after overnight travel, and an unannounced fire-alarm test woke him.

How the suite fits
Grades describe how strongly a product connects to an obligation. None discharges an obligation, and none carries a compliance warranty.
Sleepfit screens sleep health across your crew. The Merchant Shipping (Maritime Labour Convention) Act 2014 sets hours of rest in s 16 and a general health and safety duty in s 40; neither names a sleep screen. It screens; diagnosis stays with your clinicians.
About SleepfitFatiguefit4Duty records a pre-watch fatigue check for your watchkeepers, supporting the general duty in s 40 of the Merchant Shipping (Maritime Labour Convention) Act 2014. A fitness-for-duty check, not a fitness-for-duty decision - the duty call stays with you.
About Fatiguefit4DutyAwareness eLearning gives your crew recorded fatigue education, supporting the general health and safety duty in s 40 of the Merchant Shipping (Maritime Labour Convention) Act 2014. The Act names no fatigue training content.
About Awareness eLearningWas It Fatigue? structures a fatigue review after a shipboard incident, supporting the general duty in s 40 of the Merchant Shipping (Maritime Labour Convention) Act 2014. No Singapore rule requires a fatigue review. A structured judgement aid, not a determination of cause.
About Was It Fatigue?SleepWellBaby supports parents among your crew and shore staff through the most broken months of infant sleep. No Singapore shipping rule reaches sleep in new-parent households; it is offered as a benefit.

Why this pairing in Singapore
The Merchant Shipping (Maritime Labour Convention) Act 2014 sets rest hours (s 16) and a general duty (s 40), naming no fatigue tool. Sleepfit screens crew, Fatiguefit4Duty adds a pre-watch check, Awareness eLearning trains. Fatigue Lifecycle adds shipboard incident review.
