Petroleum and natural gas industry - Pipeline transportation systems - Geological hazards risk management for onshore pipeline (ISO/FDIS 20074:2019)
This document specifies the tasks, contents and basic methods of the geological hazard identification, evaluation and control of oil and gas pipelines. It is proposed to apply in geological hazard management of land-based long-distance transportation of crude oil, refined oil, natural gas, coal bed methane and coal gas pipelines. The “pipelines” referred in this document include pipelines and subsidiary facilities of pipes and the “geological hazards” include geotechnical hazards, water hazards and geological constructive hazards.**Furthermore, geotechnical hazards merely contain landslides, collapse, debris flow, ground subsidence (including only gob collapse and karst collapse), special types of soil (including only loess collapse, swelling of swelling soil, the frost heaving and thaw settlement of frozen soil and the salt heaving collapsibility and wind erosion and sand burying of salty soil); hydraulic hazards consist of slope damage, river ditch damage and farmland damage due to rainfall. Geological constructive hazards only contain faulting and earthquake.**This document is not applicable to process pipelines in oil or gas stations, urban gas pipelines, pipelines for oil refining or petrochemical factory and any other enterprises related.**This document can be used as a reference in the risk assessment of oil and gas gathering and transportation pipelines.
