This document summarizes key aspects of the water and pipeline transportation industries in the United States. It discusses the types of carriers that operate on domestic waterways and pipelines, including inland, coastal, intercoastal carriers, and private vs for-hire carriers. It also outlines the operating characteristics of these industries, noting that water carriers have relatively low costs but slower speeds, while pipelines have very low costs but limited flexibility. The document concludes by mentioning some current issues facing these industries, such as drug testing, port development challenges, and the impact of larger vessel sizes.

- 6. Water Transport Industry Overview Types of Carriers – For-hire water carriers are carriers that charge a fee for services. Includes • Exempt carriers – Excluded from federal econ. regulation adm. by STB – Carriers are exempt when transporting dry or liquid bulk commodities – Most goods transported by water are bulk commodities, thus most for-hire carriers are exempt from economic regulations • Regulated common carriers – Common carriers – Contract carriers © 2011 Cengage Learning.

- 8. Water Transport Industry Overview Types of Carriers – Coastal carriers • Operate ocean-going ships and barges along Atlantic, Pacific and Gulf of Mexico coasts • Moves large quantities of crude oil from Alaska ports to refineries along Pacific Coast – Intercoastal carriers • Operate ocean going ships and barges between coasts • Moves large quantities of oil from Gulf to Atlantic ports © 2011 Cengage Learning.
