With regard to hydrocarbon transmission lines, the analysis of susceptibility to external corrosion constitutes a fundamental tool in formulating management plans for the purpose of mitigating such threat by establishing protection barriers that are appropriate for the environmental characteristics identified.
This document presents a perspective from the management of the Weather-related and Outside Force Threat as a contribution to the determination of the corrosivity index for the electrolyte by relating the lithological units of soils with their potential for generating electrochemical oxidation-reduction processes that can lead to the corrosion of buried pipelines.
The major events involving geotechnical instability that have affected the operation of the hydrocarbon-transfer systems maintained by VIT-Ecopetrol in recent years indicate the importance of managing — in conjunction with the local authorities, the communities, and other stakeholders — policies regarding appropriate land use on and near the rights-of-way (ROWs).
With a view toward ensuring ongoing operations that are in harmony with the environment, VIT-Ecopetrol has been implementing strategies for working with the Colombian government toward the development of scenarios involving shared responsibility for risk management. These scenarios include the harmonization of regional land-use planning with the presence of the hydrocarbon-transport infrastructure; the preparation of emergency plans; and the mitigation of slope-instability events associated with intense deforestation, uncontrolled urban expansion, and other significant changes in land use.
This paper describes the advances that have been made in monitoring the actions of third parties in connection with the management of the threat and risk posed by climate and external forces, based on an analysis of the development of the region and its interaction with areas of geotechnical interest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
