In a number of the ports along the Gulf of Mexico, upstream offshore oil and gas activities are the primary drivers of the social, economic, and political landscapes. We have some understanding of how ports and communities respond to cycles in the industry, how those cycles may affect segments of the industry differential, how ports servicing expensive deepwater exploration and production may have quite different pulses than those building for and supplying the shallow shelf. In this study of the impacts of fabrication and shipbuilding on coastal communities, however, we studied locales where upstream oil and gas activities are not the only, or even the dominant shapers of the social landscape. We selected communities where oil-related shipbuilding and fabrication sectors are significant, but not the only players. Some, such as Pascagoula, have major rig fabricators, but a naval yard as well, a yard whose pulse is set by congressional appropriations and presidential directives, not by the supply and demand for oil. Others, such as Brownsville, attend closely to the supply and demand for steel and scrap metal in manufacturing plants across the border. Others have been, are, or hope to be major factors in international shipping and maritime trade. These complexities have been extensively described in the first two volumes of this report. This chapter briefly addresses the literature on ports, to borrow the building blocks for an understanding of ports and their evolution. It then offers a general overview of Gulf Coast ports, focusing on what is largely assumed to be a key characteristic of port activity—channel depth. A short compilation of shipyard typologies is then given, underscoring the variety of yards. Finally, two sections look at ramifications of the construction and ownership provisions of the Jones Act, which requires that vessels engaged in coastwise trade be built, owned, and crewed domestically. The first queries why vessels but not rigs appear to be covered under this legislation. The second takes a brief look at one community’s efforts to change its “site” characteristics to be competitive in the market for deep-water structures. |
