Temple, Barker & Sloane, Inc. (TBS) was contracted by TDPA to analyze the economics of the various alternatives for importing crude oil from various foreign sources to U.S. Gulf ports, and comparing these to the economics of the deepwater port proposed by TDPA. Chapter II, Principal Findings, summarizes the results of TBS' economic analysis. Chapter III describes the operational aspects of the transportation alternatives reviewed. Chapter IV provides an overview of conditions and interrelationships in the international tanker market. Chapter V contains a detailed description of the cost inputs and assumptions used to develop the economics data for each of the transportation alternatives. Chapter VI describes the comparative analysis of costs including a description of the methodology employed. The cost data developed in this report for shuttle tankers, lightering operations, port fees, fuel and other inputs generally are based on average costs as computed by TBS and therefore may not replicate any single firm's cost of operation. This report also contains additional data in three appendices. Appendix A contains a summary of U.S. energy supply demand factors and the outlook for crude oil imports to the U.S. Appendix B is a detailed description of the development of distribution pipeline and terminal tariffs for TDPA's proposed facility and similar tariffs for Galveston's proposed Pelican Island facility. Appendix C contains the detailed logistics costs and cost differentials by source, destination, alternative and year.
