International Maritime Health Association

What International Maritime Health Association does

International Maritime Health Association (IMHA) is a non-governmental professional association registered in Belgium in 1998 and headquartered in Antwerp, operating continuously since 1997. Its mandate is to improve the physical and mental health of seafarers and, increasingly, fishers, by convening clinicians, hygienists, port health officers, shipping-industry medical staff, academics, and students through membership services, a biennial scientific congress, training workshops, and standards-setting work. It holds consultative status at the United Nations and acts as a primary civil-society channel to the World Health Organization, the International Maritime Organization, the International Labour Organization, the International Transport Workers' Federation, the International Chamber of Shipping, the International Seafarers' Welfare and Assistance Network, and EU sectoral social-dialogue bodies.

IMHA's core product surface consists of the International Symposium on Maritime Health (ISMH, held biennially), the ICS International Medical Guide for Ships and associated Ship's Medicine Chest Program and training materials, the International Maritime Health Journal (academic publication), recurring training workshops (including the TMAS Doctor Training Workshop launched in Esbjerg in November 2024), the IMHA Podcast, the SHIP health-promotion materials developed with ISWAN, and a webshop for publications and branded merchandise. Inputs are predominantly clinical and policy expertise contributed by a multinational Board of Directors and volunteer committees; outputs are guidelines, training, events, publications, and advisory input to international regulators.

The revenue model is that of a member-funded NGO with diversified project and grant income. Public price points are modest — €150 for an individual membership and €475 for a supportive membership — with additional inflows from symposium registration and sponsorship, workshop fees, journal advertising and subscriptions, webshop sales, and grants (including from funders such as the ITF Seafarers Trust). Total annual revenue is not publicly disclosed; given the membership pricing, biennial event cadence, and grant dependency, total inflows are likely in the low single-digit millions of euros. No venture, growth-equity, or commercial funding round is disclosed, and there is no headcount trend data.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• World Medical Association (WMA): WMA is the global federation of national medical associations representing physicians worldwide. It is a broader-scale peer to IMHA in terms of being an internationally elected, membership-governed medical professional association that issues ethical and professional guidance — a template that mirrors IMHA at a much larger scale.
• International Maritime Pilots' Association (IMPA): IMPA is the international professional association representing maritime pilots, organized on a similar model to IMHA: international non-profit, country-member federations, elected leadership, consultative engagement with IMO, and a recurring international congress. It is comparable in governance template and maritime-policy interface, even though it covers navigation rather than health.
• International Chamber of Shipping (ICS): ICS is the principal international trade association for merchant shipowners and operators, headquartered in London. It is a direct partnership counterparty of IMHA (IMHA's Suzanne Stannard edited the ICS International Medical Guide for Seafarers and Fishers) and is comparable as the umbrella convener for shipping-industry stakeholders whose work IMHA's guidelines support.

Others

• World Health Organization (WHO): WHO is the United Nations specialized agency for health, with which IMHA cooperates on maritime health education and research. WHO is comparable only at the institutional/mission level rather than structure or scale, functioning as a global health policy convener rather than a peer professional society.
• International Maritime Organization (IMO): IMO is the United Nations specialized agency for maritime safety, security, and environmental regulation. IMO is a flagship institutional partner of IMHA (joint ILO/IMO medical examination guidelines) and is comparable in maritime-policy authority, but functions as a regulator rather than a peer professional association.

Direct peers

• Seafarers UK: Seafarers UK is a UK-registered grant-making charity that funds welfare, health, and safety initiatives for seafarers, fishers, and their families. It is comparable to IMHA as a maritime-focused non-profit funder and convener that frequently partners with organizations like IMHA on health promotion and welfare projects for seafarers.
• Apostleship of the Sea (Stella Maris): Apostleship of the Sea is the Catholic Church's international maritime welfare charity operating port-based chaplaincy and welfare services for seafarers globally. Like IMHA, it is a non-profit, globally active NGO whose mission centres on seafarer wellbeing, often coordinating with the same international partners (ILO, IMO, ITF).
• Société Française de Médecine Maritime (SFMM): SFMM is the French Society of Maritime Medicine and a recognized publisher in the field, including the monograph 'La Santé Mentale des Gens de Mer' on seafarer mental health. It mirrors IMHA's model as a national professional society of maritime medicine clinicians, with overlapping scientific remit and a longstanding relationship via IMHA's research network.
• International Seafarers Welfare and Assistance Network (ISWAN): ISWAN is a London-based international charity that, like IMHA, is a membership-supported NGO serving the seafarer welfare ecosystem with global reach. The two organizations already run joint programming (e.g., the 2024 Paris health promotion workshop and SHIP revisions), making ISWAN the closest functional peer to IMHA.
• International Commission on Occupational Health (ICOH): ICOH is the leading international scientific society in occupational health, with a Maritime Workers' Subcommittee. It is comparable to IMHA as a global, volunteer-governed professional association producing scientific guidance, position papers, and triennial congresses for occupational medicine specialists — including those serving seafarers.
