“…It consists of a ring that has the same internal diameter but is thicker than the pipe. The rings are welded between two adjacent pipe lengths at intervals of several hundred meters [1]. Figure 1 shows the schematic of a ring stiffened pipeline.…”

“…At higher pressures, this degradation in moment and curvature capacity is more severe. As for bending, higher D/t pipes can develop wrinkling and local shell buckling prior to the limit state induced by ovalization [1]. Such pipelines are designed to prevent buckling and collapse failures due to normal combined bending and external pressure loads, but are left vulnerable to propagating collapse failures initiated under extraordinary circumstances [2].…”

The paper reports an experimental study on the collapse of long uniformly pressurized ring-stiffened bent pipelines. Bending in the presence of external pressure is experienced by pipelines during their installation and operation. The buckling aptitude of shells is dependent on two leading geometric ratios, i.e. the length to radius and radius to thickness. In this paper, four different ring-stiffened steel pipeline specimens were tested to collapse. The evolution of the specimens behavior that has been recorded in the presence of a uniform external pressure is outlined. A thin-walled pipeline is sensitive to buckling phenomena when it experiences locally a compressive stress. It is often considered that its behavior under bending is rather similar to pure compression, but very few are the experimental investigations that precise the real behavior of it. A comparison of experimental data to empirical formulae and design recommendations is finally achieved. Consequently, it has been found that with using ring stiffeners the structure behavior against the combination of loads is improved in all loading paths. Also it has been found that buckle propagation in all manners occurs suddenly and dynamically and the amount of initial bending moment is not serious in defining the number of buckling modes. Also, the considerable effects of a longitudinal spot weld line on the buckling strength and mode shapes are verified.

“…Los oleoductos son tuberías e instalaciones utilizadas para el transporte de petróleo, que actúan como arterias en el interior de la tierra, ya que son extensas tuberías de acero y plástico, siendo la manera más económica de transportar estos productos en tierra [2]. En los oleoductos, el petróleo se mantiene en movimiento gracias a las estaciones de bombeo que son construidas a lo largo del oleoducto y permiten tener un flujo a una velocidad de 1 a 6 m/s [3].…”

El transporte de hidrocarburos es de gran importancia a nivel mundial debido a que permite la distribución desde su punto de extracción, terminales de almacenamiento, plantas de refinamiento de petróleo y de gas, hasta llegar a sus puntos de comercialización. Se analizan las diferentes formas en la que los hidrocarburos pueden ser transportados, desde una perspectiva onshore y offshore, teniendo en cuenta los procesos de midstream y downstream de los hidrocarburos, dándole una importancia significativa a los impactos ambientales asociados con estos medios de transporte, los posibles desastres que pueden generarse y cómo estos han contribuido a mejorar la propia infraestructura del transporte. También se hace una revisión de la realidad colombiana en materia de transporte de hidrocarburos, describiendo algunas oportunidades de mejora y resaltando su importancia en la vida cotidiana del país.
