What the convention requires
Welfare at sea is simultaneously a legal obligation, an operational risk control and a retention lever — and it is measured, uncomfortably, in the inspection record. MLC Title 4 welfare deficiencies were 10.1% of all Paris MoU deficiencies in 2025, the third largest category behind fire safety and machinery.
That statistic is worth sitting with. In a year when inspectors wrote up 51,797 deficiencies across 16,474 inspections, roughly one in ten concerned the conditions in which people live and work on board.
MLC 2006 obliges shipowners to provide, among other things: safe and decent working and living conditions; medical care on board comparable to that available ashore; access to medical facilities in port; health and safety protection and accident prevention; and access to shore-based welfare facilities.
The 2025 amendments, adopted at the ILO in June 2025 and expected in force in late December 2027, add materially:
| Area | What changes |
|---|---|
| Key worker status | Governments to recognise seafarers as key workers and facilitate their movement |
| Shore leave | Without visa or special permit, without discrimination; written reasons required for refusal |
| Repatriation | Facilitated without discrimination on any grounds |
| Violence and harassment | Governments and shipowners to prevent violence, sexual harassment, bullying and sexual assault |
| Fair treatment | ILO/IMO fair treatment guidelines to apply in casualty investigations |
Why mental health is an operational issue
Fatigue, isolation, long contracts, uncertainty about relief and financial stress at home degrade decision-making. Decision-making failures are the proximate cause of a large share of maritime incidents. The connection is not sentimental.
Measures that actually work
1. Connectivity, properly provisioned
Contact with family consistently ranks at or near the top of seafarer quality-of-life factors. Treat bandwidth as infrastructure, not a perk: enough for a video call, available in cabins, not metered so tightly that calling home is a budgeting decision.
2. Reliable reliefs
Uncertainty about when you go home is corrosive in a way that a long contract is not. A relief date that is honoured is worth more than a shorter contract that is not.
3. Payroll that works
Money arriving late, or arriving short after transfer fees, produces stress that follows a seafarer onto watch. Reliable payment is a welfare measure.
4. A complaint route that is actually usable
MLC requires an onboard complaint procedure with an off-ship contact. The test is whether a junior rating would use it to complain about a senior officer. If the answer is no, it is not a procedure — it is a poster.
The 2025 harassment amendments make this concrete. A workable system needs: a written policy, training delivered to every rank, at least two reporting routes (one off-ship), investigation capability that is independent of the vessel, protection against retaliation, and evidence that reports lead to action.
5. Medical access — including psychological
Medical care comparable to shore standards includes mental health. Practical provision: telemedicine access with practitioners trained in seafarer-specific issues, confidential and available in the seafarer's own language, with a clear pathway to repatriation for care when required.
6. Trained peers on board
Peer support programmes — training crew members to recognise distress and start a conversation — work at sea for the same reason they work in other isolated industries: the person most likely to notice is the one on the next watch.
7. Food and accommodation
Unglamorous and disproportionately important. Provisions quantity and variety, a qualified cook, potable water testing, cabin ventilation and temperature, and functioning recreational space. These appear in MLC Title 3 and in the deficiency statistics for good reason.
8. Shore leave, wherever it is possible
Getting off the ship, even for two hours, is a genuine reset. The 2025 amendments strengthen the right; managers can support it by choosing agents and berths where access is practical and by making the request routine rather than exceptional.
What to measure
| Indicator | Signal |
|---|---|
| Relief compliance rate | Predictability of going home |
| Rest hour non-conformances | Fatigue exposure |
| Shore leave taken per port call | Whether the right is real |
| Connectivity availability and usage | Whether the provision is adequate |
| Complaints raised, closed, and time to close | Whether the system is trusted |
| Medical repatriations by cause | Including psychological causes |
| Retention by vessel | Wellbeing problems are usually ship-specific first |
Retention by vessel is the most diagnostic. When one ship in a fleet of twelve loses people consistently, the cause is almost never the ship.

Frequently asked questions
Is mental health covered by MLC?
Medical care obligations under MLC Title 4 are not limited to physical health, and welfare provisions apply broadly. Several flag states and industry bodies have issued specific guidance on psychological wellbeing at sea.
What do the 2025 MLC amendments require on harassment?
Governments and shipowners are to take measures to prevent shipboard violence, sexual harassment, bullying and sexual assault, aligned with the Violence and Harassment Convention, 2019. Entry into force is expected in late December 2027.
Does connectivity really affect safety?
Indirectly but meaningfully. Isolation and family stress degrade concentration and decision quality, and both are reduced by reliable contact home.
Who can a seafarer contact if the onboard route fails?
The designated off-ship contact in the vessel's complaint procedure, the flag state, the port state, ITF inspectors, and seafarer welfare organisations in port.
