Speaking of the Jones Act
In reality, the Jones Act has yet to be an issue in the response efforts. The Deepwater Horizon response team reported in a June 15 press release that there are 15 foreign flagged ships currently participating in the oil spill cleanup. None of them needed a waiver because the Jones Act does not apply. The Jones Act is a trade and commerce law that was enacted in 1920 as part of a larger Marine Merchant Act. It requires all trade delivered between U.S. ports to be carried in U.S. flagged vessels constructed in the United States and owned by American citizens. The law states its purpose is to develop a merchant marine for national defense and commerce.
