About the Indonesia Flag

Registry Authority

The Indonesian flag is administered by the Directorate General of Sea Transportation under the Ministry of Transportation. Indonesia has one of the world's largest national-flag fleets by ship count — over 10,000 vessels — driven primarily by domestic coastal trade requirements among the country's 17,000+ islands.

Why Ships Register in Indonesia

Indonesia's strict cabotage law (Presidential Instruction No. 5/2005) reserves all domestic seaborne trade — passenger, cargo, and offshore-support — for Indonesian-flagged, Indonesian-owned, and Indonesian-crewed ships. This single requirement explains the size of the flag and the dominance of small ferries, tugs, barges, and coastal tankers in the fleet.

Notable Operators

Pertamina International Shipping, Berlian Laju Tanker, Soechi Lines, Pelni (the state passenger-ship operator), Meratus Line, Salam Pacific Indonesia Lines, and a long tail of mid-size operators flag tonnage in Indonesia. The fleet includes a large share of tugs, barges, and coal-loading shuttle vessels.

Trade Routes

Indonesian-flagged ships dominate domestic inter-island trade between Java, Sumatra, Kalimantan, Sulawesi, Bali, and the eastern islands; coal shuttle services from Kalimantan mines to power stations and export terminals; and Pertamina's domestic crude and product distribution. Offshore-support ships serve the country's upstream oil and gas fields.
