MLC 2006: A Seafarer's Rights Guide for Ship Management Companies

The Maritime Labour Convention, 2006 (MLC 2006) is often described as the fourth pillar of international maritime regulation, standing alongside SOLAS, MARPOL and STCW. Where STCW governs competence and the others govern safety and pollution, MLC 2006 governs people — the working and living conditions of the seafarers who make global trade possible. For ship management companies and manning agencies, it is not a welfare aspiration but a binding legal framework enforced by flag states and port state control alike.

Why MLC 2006 is called the seafarers' bill of rights

Before MLC, seafarers' rights were scattered across dozens of older ILO conventions that few states had ratified consistently. MLC 2006 consolidated them into a single, enforceable instrument that entered force in 2013 and now covers the overwhelming majority of world tonnage. Its genius is in its enforcement teeth: a ship can be detained by port state control for serious breaches, exactly as it can for a safety deficiency. Crew welfare became an operational reality, not a moral footnote.

MLC 2006 turned seafarer welfare from something owners ought to provide into something they must prove they provide — documented, inspectable and enforceable in any port.

The five titles of the convention

MLC is organised into five titles that together cover the seafarer's entire working life:

1. Title 1 — Minimum requirements for seafarers to work on a ship. Minimum age, medical fitness (the ENG1 or equivalent), training and qualification, and properly regulated recruitment and placement services.
2. Title 2 — Conditions of employment. The Seafarer Employment Agreement, wages, hours of work and rest, leave, and repatriation.
3. Title 3 — Accommodation, recreation, food and catering. Standards for living quarters, recreational facilities, and the quality and quantity of food and drinking water.
4. Title 4 — Health protection, medical care, welfare and social security. Medical care on board and ashore, shipowner liability, health and safety, access to welfare facilities, and social security protection.
5. Title 5 — Compliance and enforcement. The Maritime Labour Certificate, the Declaration of Maritime Labour Compliance, inspections and on-board complaint procedures.

The Seafarer Employment Agreement

At the heart of Title 2 is the Seafarer Employment Agreement (SEA). Every seafarer must have a clear written contract, in a language they understand, signed before joining, with a copy in their possession. The SEA must set out the parties, the wages and how they are calculated, paid leave, the conditions of repatriation, health and social security benefits, and notice periods. For a manning agency this is non-negotiable groundwork: an emergency placement does not excuse an absent or non-compliant SEA.

Hours of rest

MLC, working alongside STCW, sets clear limits on fatigue. Seafarers are entitled to a minimum of 10 hours of rest in any 24-hour period and 77 hours in any 7-day period, with rest divisible into no more than two periods, one of which is at least six hours. These are not guidelines; they are recorded, audited, and directly linked to safe watchkeeping. Manning levels that quietly rely on crew breaching rest hours are a compliance failure waiting to be found.

Recruitment and placement: the agency's own obligations

MLC 2006 regulates manning agencies directly. A compliant recruitment and placement service must:

• Charge no fees to the seafarer for finding employment — the cost falls on the shipowner, not the worker.
• Maintain an up-to-date register of the seafarers it places.
• Ensure seafarers are informed of their rights and duties under the SEA before engagement.
• Verify that seafarers are qualified and hold the documents required for the job.
• Operate a system of protection to compensate seafarers if the agency or the shipowner fails to meet obligations.

This is one of the clearest dividing lines between a professional agency and an exploitative one. The "no fees to the seafarer" principle is fundamental, and any arrangement that charges crew for jobs is a direct breach.

Repatriation: a right, not a favour

One of MLC's most important protections is the right to repatriation — a seafarer must be returned home at the end of their contract, or in cases of illness, injury, shipwreck or the shipowner's insolvency, at no cost to the seafarer. The 2014 amendments strengthened this further with financial security requirements, so that abandoned crews are not left stranded without wages or a way home. Managers must ensure the financial security certificate is valid and that repatriation is planned, not improvised.

What compliance looks like in practice

For a ship management company, MLC 2006 compliance is continuous and documented. The vessel carries a valid Maritime Labour Certificate and Declaration of Maritime Labour Compliance; SEAs are in place and held by every crew member; rest-hour records are maintained honestly; accommodation, food and welfare meet the standard; and an on-board complaint procedure exists that crew can actually use without fear. When port state control boards, none of this should require scrambling — it should already be true. Treating MLC as the human foundation of crewing, rather than a certificate to renew, is what separates a responsible operator from one waiting for a detention.
