The purpose of this legislation, known as the Allied Partnership and Port Modernization Act, is to allow certain foreign dredge ships, specifically those from NATO countries and major non-NATO allies, to operate in U.S. waters. This aims to enhance dredging capabilities and improve port infrastructure in the United States. Key provisions of the Act include the amendment of existing laws to permit dredging by vessels that are either documented in NATO member countries, built by these countries or major non-NATO allies, and owned or operated by entities from NATO countries.
