Introduction to the Maritime Labour Convention (MLC)
The Maritime Labour Convention (MLC), adopted in 2006, marks a significant milestone in seafarer rights. It consolidates over 65 international labor standards. This treaty aims to protect seafarers globally, given the shipping industry's international nature and its exemption from national labor laws. It represents the most significant advancement in seafarers' rights in over a century.
The MLC's primary goal is to ensure comprehensive protection of seafarers worldwide. It aims to create a fair environment for all Member States and shipowners. The Convention was adopted with no opposition, involving 106 countries and over 1,100 participants. It encompasses 37 ILO maritime conventions and 30 recommendations, addressing various aspects of seafarer protection and maritime labor laws.
What is the Maritime Labour Convention?
The MLC is an International Labour Organization (ILO) convention that consolidates minimum seafarer treatment standards. It covers employment conditions, working hours, rest, accommodation, and health protection in 100 pages.
The MLC applies to most commercial ships, with exceptions for smaller vessels (200 gross tons and below) not engaged in international voyages. The Convention defines seafarers broadly, encompassing all individuals employed on ships. This definition ensures that a wide range of maritime workers benefit from the MLC, enhancing maritime safety and protection.
Key objectives of the MLC
The MLC's primary objectives are to:
Ensure comprehensive worldwide protection of seafarers' rights
Establish a level playing field for Member States and shipowners committed to providing decent working and living conditions
Promote fair competition in the maritime industry by eliminating substandard shipping practices
Enhance compliance and enforcement mechanisms, such as onboard certificates of compliance and a "no more favorable treatment" clause for non-ratifying states
MLC Milestone | Date |
Drafted | 7 February 2006 |
Signed | 23 February 2006 |
Entered into force | 20 August 2013 |
Ratifications (as of August 2021) | 97 states, representing over 97% of global shipping |
The MLC has profoundly impacted the maritime industry, promoting safety, seafarer protection, and fair competition. By August 2021, 97 states had ratified the Convention, covering over 97% of global shipping. This widespread acceptance underscores the MLC's critical role in the maritime community.
Minimum Requirements for Seafarers to Work on a Ship
The Maritime Labour Convention (MLC), 2006, establishes critical standards to safeguard the rights and well-being of the approximately 1.2 million seafarers globally. It mandates minimum requirements for seafarers to work on a ship, aiming to ensure decent working and living conditions. This ensures a level playing field for member states and shipowners committed to these principles.
The MLC, effective since August 20, 2013, applies to vessels over 500 Gross Tonnage (GRT). It requires these vessels to carry a valid MLC certificate. This certificate, valid for up to five years, confirms compliance with the convention's stipulations on seafarer working conditions, health, and safety.
Age Restrictions and Prevention of Child Labor
One of the MLC's key provisions is the minimum age requirement for seafarers. Documentation onboard must verify that all seafarers are a minimum of sixteen (16) years old. This effectively prevents child labor in the maritime industry.
Medical Certification Requirements
The MLC mandates medical certification for all seafarers to protect their health and safety. Medical certificates for seafarers under 18 years of age are valid for one year, while those above 18 are valid for up to two years. These requirements ensure that seafarers are physically fit to carry out their duties and can withstand the demands of working on a ship.

Regular inspections, conducted at intervals not exceeding 36 months, verify ongoing compliance with MLC requirements. Failure to meet these standards may result in the withdrawal of the MLC certificate by the flag state. This highlights the importance of maintaining proper seafarer working conditions and upholding maritime employment rights.
MLC Requirement | Details |
Minimum Age | All seafarers must be above 16 years of age |
Medical Certificate Validity | 1 year for seafarers under 18; 2 years for those above 18 |
Inspection Interval | Not to exceed 36 months |
The MLC sets these minimum requirements to protect seafarers from exploitation and ensure their well-being. Given that a significant portion of seafarers come from diverse cultural, national, and political backgrounds, consistent global adoption of the MLC is crucial. It is essential for providing effective welfare services and maintaining decent working conditions across the maritime industry.
Conditions of Employment for Seafarers
The Maritime Labour Convention (MLC) 2006, often referred to as the seafarers' bill of rights, establishes minimum standards for employment conditions of the estimated 1.5 million seafarers globally. It came into effect on 20 August 2013, applying to all commercial seagoing ships in international waters. This includes vessels of 500 GT or above.
Countries that ratified the MLC must adhere to its 68 existing conventions and recommendations. The Convention mandates enforcement through a system of inspection and certification for ships. It also includes a "no more favourable treatment" clause, preventing ships from non-ratifying states from gaining operational advantages over those from ratifying states.
Seafarers' employment agreements
The MLC stipulates that seafarers' employment agreements must include the seafarer's name, date of birth, and birthplace. Seafarers must be given an opportunity to review and sign their agreement. They must also have access to a signed original. Collective bargaining agreements, if applicable, must also be available on board.
Wages and payment of wages
The MLC requires that seafarers be paid for their work at no greater than monthly intervals. Wage and payment records must be provided to them. Amendments introduced in 2017 ensure that seafarers receive up to four months of outstanding wages and reasonable expenses in cases of abandonment.
MLC Requirement | Details |
Minimum notice period for early termination of employment agreement | 7 days |
Frequency of wage payments | At no greater than monthly intervals |
Employment agreement to include seafarer's name, date of birth, and birthplace | Mandatory |
Seafarers' access to signed original of employment agreement | Required |
Hours of work and rest
The MLC sets out minimum hours of rest and maximum hours of work to ensure the safety and well-being of seafarers. Flag states are responsible for enforcing these requirements. They must also address concerns related to forced labour conditions, which affect approximately 30% of seafarers according to maritime labor surveys.
Entitlement to leave
Seafarers are entitled to paid annual leave, as well as shore leave for their health and mental well-being. In cases where seafarers are held captive due to piracy, their employment agreements remain in effect irrespective of the expiry date. This ensures their wages are protected.
The enforcement regime and compliance checks are designed to address the concerns of the 1.5 million global seafarers effectively.
Accommodation, Recreational Facilities, Food, and Catering
The Maritime Labour Convention (MLC) addresses a wide array of issues related to the living and working conditions of seafarers, ensuring that their rights are upheld and that they work in environments that promote safety, dignity, and respect. Among its various provisions, Title 3 of the MLC specifically focuses on the critical aspect of ensuring decent accommodation and recreational facilities onboard ships. This title emphasizes the importance of providing seafarers with living quarters that are not only safe and hygienic but also conducive to rest and relaxation.
The convention stipulates that ships must provide adequate space, ventilation, lighting, and access to necessary amenities such as clean water and sanitation facilities. Furthermore, it mandates that seafarers have access to recreational facilities that allow them to engage in leisure activities, socialize, and pursue hobbies, all of which contribute to their mental and emotional health.
MLC recognizes that the psychological well-being of seafarers is intrinsically linked to their ability to perform effectively in their roles. By fostering a supportive living environment, the convention not only enhances the quality of life for those working at sea but also contributes to the overall efficiency and safety of maritime operations. The inclusion of provisions for recreational activities and social interaction is particularly important, as it helps mitigate feelings of isolation and stress that can arise from extended periods away from family and friends.
MLC's regulation also outlines minimum requirements for crew accommodation. For instance, in ships under 3,000 GT, single berth sleeping rooms must have a floor area of at least 4.5 square meters. Ships over 10,000 GT must provide a minimum of 7 square meters per seafarer.
Onboard Accommodation Requirements
Ship Size (GT) | Minimum Floor Area for Single Berth Rooms |
Less than 3,000 | 4.5 square meters |
3,000 to 10,000 | 5.5 square meters |
Over 10,000 | 7 square meters |
Recreational Facilities for Seafarers
The convention also sets standards for food and catering. It ensures that seafarers receive nutritious meals and have access to safe drinking water. Ships operating under the MLC framework are subject to regular inspections to verify compliance with these provisions.
Each seafarer must be provided with a clothes locker with a minimum volume of 475 liters and a drawer of no less than 56 liters capacity.
Health Protection, Medical Care, Welfare, and Social Security Protection
Onboard and Onshore Medical Care
The MLC mandates immediate medical attention for seafarers, requiring ship owners to them to disembark them for onshore care. This ensures timely and adequate health care. Ships must also carry necessary medical supplies and equipment for common health issues.
Shipowners' Liability for Seafarers' Health
Shipowners are responsible for medical costs due to illness, injury, or death during employment. This liability covers the period from contract start to repatriation or medical benefit claims.
Social Security and Welfare Provisions
The MLC provides social security and welfare for seafarers and their families. Key provisions include:
Access to shore-based welfare facilities
Social security protection, such as healthcare and pension benefits
Repatriation rights, ensuring seafarers can return home at no cost after serving a maximum of 12 months on board
Compliance and Enforcement of the MLC
Flag States bear the responsibility of issuing Maritime Labour Certificates (MLCert) and Declarations of Maritime Labour Compliance (DMLC) for ships. The DMLC consists of two parts: Part I details the flag state's laws, while Part II outlines the shipowner's commitments to upholding MLC rights for seafarers onboard. Every ship must carry these documents to inform seafarers of their rights and the shipowner's obligations.

Port State Control Measures
Port State authorities have the power to inspect ships for compliance, ensuring that there are no unfair advantages for non-ratifying states. Port State Control Officers (PSCOs) are required to conduct initial investigations into MLC complaints and must seek resolution at the shipboard level. If shipboard resolution fails, PSCOs may impose deficiencies, which can lead to the vessel being detained.
MoU | MLC-related Deficiencies (Post-MLC2006) |
Paris MoU | Above 14% |
Tokyo MoU | Above 14% |
Other MoUs | Below 10% |
Onboard Complaint Procedures
Onboard complaint procedures are available for seafarers if their rights are not respected. If issues remain unresolved, seafarers can escalate the complaint to the master of the ship and external authorities, including flag state, port state, shipowner, trade union, and ITF inspectorate.
Detention of the ship and withdrawal of the MLCert are potential sanctions for non-compliance with the MLC.
Amendments and Additional Protections for Seafarers
The Maritime Labour Convention (MLC, 2006) has seen significant updates to bolster the rights and welfare of seafarers globally. These revisions, endorsed by the Special Tripartite Committee and ratified by the 110th Session of the International Labour Conference on June 6, 2023, are set to take effect on December 23, 2024. This timeline is contingent upon no formal disagreement from more than 40% of ratifying Members, representing at least 40% of the gross tonnage of ships.
The Covid-19 pandemic underscored the imperative for enhanced seafarer rights advocacy. It revealed that hundreds of thousands of seafarers endured prolonged service, were unable to leave their vessels, or were stranded ashore, unable to replace those on board. The amendments aim to rectify these issues, offering additional safeguards for seafarers.
Amendments addressing seafarer abandonment
Regulation 2.5 (Repatriation) has been revised to expedite repatriation processes, focusing on abandoned seafarers. The updates mandate that seafarers are informed of their compensation rights before and during the contract period. They also underscore the shared responsibility for repatriation among port states, flag states, and labour supplying countries.
Financial security for seafarers' death or long-term disability
The amendments introduce provisions for financial security in cases of seafarers' death or long-term disability. Flag states are now obligated to investigate and report seafarer deaths to the ILO. A global register of seafarer deaths is also part of the reporting requirements. The amendments also clarify the scope of financial security certificates, resolving discrepancies between registered owners and operational management companies.

Other notable amendments include:
Prohibition of recruitment fees charged to seafarers (Regulation 1.4)
Provision of appropriate social connectivity and internet access by shipowners and port States (Regulation 3.1)
Ensuring suitable food in terms of quantity, nutritional value, quality, and variety, provided free of charge (Regulation 3.2)
Facilitating prompt disembarkation of seafarers needing immediate medical care (Regulation 4.1)
Mandating the provision of appropriately-sized personal protective equipment for seafarers (Regulation 4.3)
Impact of the MLC on the Maritime Industry
Benefits for Seafarers and Their Families
MLC ensures fair employment practices for seafarers, a cornerstone of the convention. It mandates access to medical care, protection against wrongful termination, and reasonable communication and internet access. These provisions have significantly improved the safety of their work environment, reducing exhaustion and stress.

Recent amendments to the MLC, which took effect on December 1, 2024, further enhance seafarers' well-being. They ensure access to high-quality meals and drinking water. The amendments also promote safety and gender equity by providing appropriate personal protective equipment.
