Esta edición del Boletín entrega un recuento de la Conferencia sobre el Efecto Año 2000 en los Sistemas de Transporte del Hemisferio Occidental, que se celebró en Cancún, México, en mayo de 1999. Asimismo, proporciona un nuevo análisis sobre el transporte marítimo en Sudámerica, elaborado y presentado por Uruguay en la Quinta Reunión Ordinaria de la Conferencia de Ministros de Transportes, Comunicaciones y Obras Públicas de América del Sur, Cochabamba, Bolivia, en abril de 1999.

En este estudio se analiza el rol de América Latina y el Caribe dentro del contexto global en el que se desenvuelve el sector de los hidrocarburos. Asimismo, se abordan los factores que incidieron en la oferta y la demanda, y las causas de la volatilidad en los precios del petróleo y estudia los impactos sobre el sector fiscal, dividiendo el análisis entre los países productores/exportadores de petróleo y los consumidores/importadores. Finalmente, se estudian los impactos sobre otros ámbitos de la economía, lo que incluye un análisis sobre los nexos del petróleo con otras materias primas, los impactos sobre el sector externo, el tipo de cambio, crecimiento económico, endeudamiento externo y las inversiones en el sector petrolero y de las energías renovablesEl estudio cierra con una serie de recomendaciones y conclusiones

Having in mind that petroleum's history presents a huge growth, the exploration and production areas have been receiving lots of investments, in order to attend the increasing demand for gas and petroleum. Looking through that scenario, new technologies have been evolving in favor of discovering new natural petroleum deposits and act with effectiveness in truly deep waters without giving up the worldwide best operational security practices. The use of rigid pipes in marine installations have been rising quickly and, thanks to this reality, the many storage and pipe launching forms became study objects and are getting improved. The analysis of steel API X70 characteristics, proving that they are suitable for use in pipes developed to transport gas and petroleum is the theme of this presentation. A tensile test was conducted to determine the base metal's mechanical properties, draining's tension, traction's resistance, elasticity's modulus and maximum tension. An aspect that is concerning too is the metallographic analysis, in order to determine the studied iron's microstructure. Results of analyzes showed that the steel has high resistance, with good capacity for deformation and well defined yield point, concluding suitable for the application in question

Despite the growing concern in seeking more sustainable energy sources, oil demand is likely to grow in coming years. To keep up with this growth, the oil industry has increasingly invested in innovation and efficiency. Knowing that, new technologies have been developed to explore deeper waters, without giving up the best practices in worldwide operational safety. The use of rigid pipelines in deepwater offshore facilities is increasing quickly and because of this, the ways of storing and launching pipe have been studied and perfected. In this paper the Bauschinger effect on API 5L X70 steel was analyzed proving that there was a reduction in yield strength when an effort was applied in a previous direction, then an effort was then applied in the opposite direction. To observe this phenomenon, the tensile test was conducted to determine the mechanical properties of the base metal, such as yield stress, tensile strength, elasticity and maximum tensile, so then compare it with the results obtained in the Bauschinger Effect Test. The analysis results showed that the steel had high resistance, with good plastic deformation capacity without failing, well-defined yield point, showing itself appropriate for the operation of oil and gas pipes
