What Is the Maritime Labour Convention?
The Maritime Labour Convention (MLC 2006) is an International Labour Organization (ILO) convention adopted in 2006 and entered into force on 20 August 2013. It consolidates and updates more than 65 previous ILO maritime labour instruments into a single, comprehensive framework that establishes minimum requirements for seafarer working and living conditions. MLC is widely recognized as the fourth pillar of international maritime regulation, complementing SOLAS (safety), STCW (training and certification), and MARPOL (environmental protection) to form the complete regulatory foundation for the shipping industry.
Key Titles and Requirements
MLC is organized into five titles covering every aspect of seafarer welfare. Title 1 addresses minimum requirements for seafarers to work on ships, including minimum age, medical fitness, and training. Title 2 covers conditions of employment — seafarer employment agreements, wages, hours of work and rest, leave entitlement, and repatriation rights. Title 3 sets standards for accommodation, recreational facilities, food, and catering. Title 4 deals with health protection, medical care, welfare, and social security. Title 5 establishes the compliance and enforcement framework, including flag state inspection, port state control, and the Maritime Labour Certificate (MLC certificate) that ships of 500 GT and above in international trade must carry.
DMLC and Enforcement
Compliance with MLC is demonstrated through a two-part Declaration of Maritime Labour Compliance (DMLC). Part I is issued by the flag state and lists the national requirements implementing each MLC standard. Part II is prepared by the shipowner and describes the specific measures adopted onboard to meet those requirements. Port state control officers inspect vessels for MLC compliance and can detain ships that fail to meet minimum standards, making MLC enforcement one of the most impactful regulatory mechanisms in shipping.
Crew management software supports MLC compliance by tracking seafarer employment agreements, monitoring hours of work and rest to ensure they remain within legal limits, managing leave entitlements and repatriation schedules, maintaining medical certificate records, and generating the documentation required for flag state and port state inspections. Digital platforms provide real-time visibility into MLC compliance status across an entire fleet, enabling proactive management rather than reactive responses to inspection findings.
