Planet Earth has recently witnessed a change in the behavior of climate variables (including temperature, rainfall, etc.), primarily attributed to global warming. This climate change is a threat that is materializing and has affected elements of the infrastructure, ecosystems, and environmental conditions worldwide, as well as the National Development Plans [“Planes Nacionales de Desarrollo”]. The hydrocarbon-transport infrastructure in Colombia has not escaped the effects of climate variability. Therefore, a strategy must be devised to manage the risk and to adapt these systems in the light of potential harmful effects, and also to supplement or improve the mitigation measures for the effects generated by the oil industry through its operations. Climate disturbances lead to an increase in the likelihood of landslides, wildfires, floods, avalanches, and other natural hazards. The major climate changes that have been identified and that may affect hydrocarbon-transfer systems in Colombia are the following ones: • A gradual increase in temperature. • Changes in the patterns and amounts of rainfall. • A rise in sea level. • An increase in the severity and frequency of extreme weather events. The strategy for adapting the hydrocarbon-transport systems in light of climate change focuses primarily on the following points: 1. Acquiring more knowledge about the climatic changes that are expected to occur in Colombia, including the change in the major climatic variables and their georeferencing. 2. Diagnosing the transport systems and their spatial correlation with future climate scenarios. 3. Identifying the industries or elements of the infrastructure that are most vulnerable to the expected climatic changes. 4. Proposing measures that will add strength and/or resilience, so that the elements of the system can resist the effects of climate change, or overcome them within a short period of time, without affecting the Business. 5. Prioritizing the interventions to be performed at sites that are critical to the Business. 6. Monitoring and tracking the climatic variables in order to adjust the susceptibility models in light of the major impacts (e.g., landslides). The primary goal of this paper is to outline the initiative that has been proposed by the Technical Asset Management Bureau [“Gerencia Técnica de Activos”] (GTA) of Ecopetrol’s Office of the Vice President for Transportation and Logistics [“Vicepresidencia de Transporte y Logística”] (VIT Ecopetrol) in order to adapt the currently operating transport systems so that they can deal with climate change, while ensuring their healthful and safe operation, in compliance with the applicable technical legal requirements. Another goal of this paper is to highlight the advances that have been made by the GTA in the procurement, compilation, analysis, and use of climate information and geotechnical data as basic elements of risk management.
The realization of the weather-related and outside force threat has historically caused losses of containment with their subsequent social, environmental, economic and image consequences for Ecopetrol. The zones in which these phenomena occur are characterized by the interaction of transmission systems with an environment that is complex in its topographical, geological-geomorphological and climatic conditions, and because of the anthropic impact of changes in land use. In Ecopetrol’s office of the Vice-president for Transportation Logistics (VIT-Ecopetrol), a threat management strategy has been proposed that seeks to minimize the vulnerability of the pipelines to processes that can impact on operating efficiency or that, because of their degree of complexity, require comprehensive management in order to guarantee operation at tolerable levels of risk. This article presents a panorama of the work performed with regard to the validation of the threat and risk levels of the assets, the internal analyses performed by geotechnical professionals for formulating the plans for the management of assets and the accompaniment of such in order to achieve the continuous operation of the transmission systems.
The main objective of the integrity and maintenance professionals of hydrocarbon transportation companies is to ensure the integrity and availability of transportation systems by monitoring and controlling the risks to which they are exposed. This article presents a series of aspects that give scope to a structured maintenance and integrity management program, and that can be established in each company based on its organizational structure and culture. Some examples are presented to take into account in geohazard management and that focus on achieving a holistic and prospective view of the professionals who manage geotechnical risk.
In slope movements with slow strain rates that affect rights of way (ROW) or its surrounding areas, an appropriate Inline Inspection (ILI) program with inertial modules may provide timely and quality information, with ease of matching with geotechnical events and lower costs than conventional monitoring methods. In virtue of above, for structural integrity management of pipeline, this information is necessary and its integration with the information obtained from other sources such as ROW patrol, terrain monitoring and pipeline monitoring. This document contains information related to the tracing, analysis and executed activities in the study case located in Colombian center-west, where neotectonic effects and a common ROW with a main highway converged.
In recent years, the Colombian government has strengthened its legislation moving towards a disaster risk management system (Law 1523 in 2012) and has established guidelines on the role of public and private entities (decree 2157 in 2017) when defining the structure of disaster risk management plans. This paper presents the advancements on Natech risk management implementation in Cenit (major Colombian pipeline operator of hydrocarbons transport), to identify areas of potential disaster based on the application of its geohazards assessment model that considers prevention specific elements and consequence analysis.
