In this project, geotextile tube technology is adopted as part of an integral solution for beach erosion problems at the Dos Bocas marine facilities for Petroleos Mexicanos (PEMEX). The solutions designed consisted of: geotextile tubes (GT) filled with sand working as beds for oil conduction pipes that were previously in risk of collapsing due to sand foundations lost within the surf zone, installation of a submerged breakwater using GT along 1.9 km of coastline, installation of 62000 m3 of beach nourishment for coastline stabilization. This article describes elements of the design criteria and installation process, field survey data before and after beach profiles comparison and graphical material is presented, and analysis corroborating natural beach recovery after breakwater installation. Post-construction evidence is also given, leading to the conclusion that this project has worked as expected, ensuring long-term oil conduction and storage facility integrity. The following conclusions are highlighted for this project: Adopting an integral solution guarantees a long-term solution to this beach erosion problem. The versatility of the GT allows usage in an innovative application such as pipe support elements. As in other projects in Mexico (Alvarez et al., 2006; Alvarez and Espinoza, 2008; and Escalante and Solis, 2008), GT working as coastal protection structures have acted as effective and environmentally friendly alternatives for shore stabilization. Beach nourishment, in conjunction with shore protection structures, is a good alternative to increase the longevity of beach reconstruction projects. GT structure construction requires comparatively minimal logistics and equipment, while offering installation and maintenance cost benefits. Regardless of the successes of this project and the proven potential of GT to be effective for shore protection, based on site observations during project construction, there are issues that require continued monitoring and research, including: GT durability against UV exposure. scour apron performance for assuring settlement control. strength of the seams and filling port sections of manufactured geotextile tubes.
