About the Marshall Islands Flag
Registry Authority
The Marshall Islands registry is administered by International Registries Inc. (IRI) on behalf of the Office of the Maritime Administrator of the Republic of the Marshall Islands. Headquartered in Reston, Virginia, with a network of 28+ offices worldwide, IRI manages one of the three largest open registries — the Marshall Islands flag now ranks third globally by deadweight, with around 5,000 vessels.
Why Ships Register in the Marshall Islands
The flag is on the Paris MOU, Tokyo MOU, and US Qualship 21 white lists, and has held that status for an unusually long stretch. Owners cite the registry's responsive service, full IMO convention compliance, no nationality restriction on crew, and a corporate framework that allows both ship registration and the underlying owning company to be domiciled together under Marshallese law — a structure favoured by US-listed tanker and gas-carrier companies.
Notable Operators
Many of the largest US-listed shipping companies fly the Marshall Islands flag, including Frontline, Euronav, DHT, International Seaways, Teekay, Golar LNG, GasLog, and Star Bulk. Greek owners such as Angelicoussis Group and TMS Cardiff Gas also flag substantial fleets here.
Trade Routes
Marshall Islands tonnage is dominated by crude and product tankers on Middle East–Far East and US Gulf–Europe trades, LNG carriers serving Qatar, Australia, and the US Gulf, and dry-bulk carriers on the iron-ore and grain trades to China and Southeast Asia. The flag is rare on liner container services but common on chemical and gas carriers.
