A PGMP is a set of practices and procedures used to systematically identify, evaluate, and manage geohazards for the purposes of reducing the risk of damage to a pipeline system to an acceptable level. A PGMP is operated for the entire lifespan of the pipeline from conception and design, to construction,operation, and until the pipeline system is decommissioned. Thus, the PGMP should be designed and implemented in such a way that critical information will be maintained and accessible for the lifetime of the pipeline.
Because a variety of different groups participate in the design, construction and operation of a pipeline,overall ownership of the PGMP rests with the operator. The operator shall designate an individual or organization (the“PGMP team”) to administer the PGMP during and between the different phases. The PGMP team may be the operator’s personnel or a qualified third party entrusted by the operator. In case of replacement of one organization by another, a proper handover of geohazard risk management duties shall be ensured. When the geohazard risk management is assigned to a third party, the operator shall be continuously and intimately engaged with the third party to ensure that the interests and needs of the operator and all stakeholders are being adequately addressed and protected.
Determine the width of the corridor for which the identification process should be conducted. This width can be variable, depending on the terrain and geohazards present. The corridor width should at a minimum be as wide as the routing corridor and should ideally be conducted to a distance equivalent to the distance from which hazards initiating outside of the proposed route(s) could affect the route, such as long run-out landslides. In this phase the corridor width for identification process might be in the order of 5 km to 10 km, depending on the nature of the geohazard: erosion and mining subsidence will have a very narrow evaluation corridor, whereas seismic and pyroclastic threats might have a much wider evaluation corridor. Debris flows (from steep mountainous streams) and landslides triggered in bedrock require a corridor width up to potential source, which is height of land, i.e. crest elevation.BS EN ISO 20074 pdf free download.
