# Singapore-flagged tanker runs Colombian cabotage route with 60,000 barrels

The vessel 'Mockingbird' delivered hydrocarbons between Buenaventura and Tumaco, a domestic move that under U.S. law would be reserved for American-flag ships.

The Singapore-flagged tanker 'Mockingbird' arrived at Tumaco after moving 60,000 barrels of hydrocarbons from Buenaventura, a cabotage operation between two Colombian ports. [^1] Cabotage is the transport of goods or passengers between two points in the same country by a vessel registered in another country. [^2]

The 'Mockingbird' call illustrates a domestic move that under U.S. maritime cabotage law would be restricted to American-flag vessels. The Jones Act prohibits foreign-flag bulk carriers from shipping cargo from the U.S. West Coast to Hawaii. [^5] A 2011 MARAD report found operating a Jones Act-compliant vessel costs $12,600 more per day than an open registry ship, with almost 90% from higher crew costs. [^6]

The read here is that foreign-flag cabotage operations like the 'Mockingbird's' Colombia run are routine outside the United States, where the Jones Act's domestic shipping restrictions do not apply. The U.S. Virgin Islands are exempt from U.S. maritime cabotage laws due to an agreement made during World War I. [^4] In 1982, the Alaska Statehood Commission estimated the Jones Act drained $225 million a year from Alaska's oil industry and $41 million from other sectors. [^7]
