摘要
秘鲁Camisea管道运输系统(PTS)由Perú (TGP)所有,Compañía Operadora de Gas (COGA)运营,起始于亚马逊雨林,穿过安第斯山脉(4850msnm),最终下降到太平洋海岸。PTS已经运营了10多年,拥有天然气(NG)和液化天然气(NGL)输送管道。天然气管道长888公里,包括两个环路(沿海和山区分别为105公里和18公里)。天然气天然气管道长557公里。从起点(0公里)到210公里,路权(RoW)位于亚马逊雨林的岩土工程环境中。然后,在210公里到420公里之间,PTS穿过安第斯山脉。最后,在420公里和730公里之间的RoW位于秘鲁太平洋沿岸。TGP的PTS系统可以识别、分析和控制可能影响管道完整性的不同类型的威胁。该作业是根据作业的管道完整性管理(PIM)中定义的国际标准制定的。因此,对第三方损害(TPD)、地质灾害、外部和内部腐蚀等危害进行了分析。然而,由于秘鲁的经济增长和发展,在某些情况下,由于个人、社区或工业活动对保护区周围环境的干预,导致地质灾害的程度被自发地改变和激活。因此,RoW的稳定程度对于分析天然气和天然气管道的完整性是必要的。本文描述了一些由与TPD相关的活动引发的TGP的PTS RoW稳定性变化的实际案例。报告强调,减灾行动的确定、分析、定义和执行是以横向方式进行的,涉及不同业务领域的参与,例如:整体维护、岩土技术、完整性、社会管理等。所有的活动都是在保持社区、环境和基础设施之间的平衡的情况下进行的。考虑的一些情况包括:工业区水箱故障引发的洪水和冲刷,由于障碍物造成的渠道冲刷,以及靠近排水区的建筑产生的不稳定的斜坡过程。如今,该公司开展了一些活动,以减轻TPD产生的地质灾害。其中一些活动除其他外包括:提高社会认识、技术会谈、与工业和地方行政实体达成协议、岩土工程维修和监测。此外,还强调指出,上述所有缓解行动都是以不同业务领域之间的横向方式进行的。然后,将收集到的信息妥善保存在地理信息系统数据库中。
Practical Cases: Geohazards on RoW Generated by Third Party Damage
Camisea Pipeline Transportation System (PTS) in Peru, owned by Transportadora de Gas del Perú (TGP) and operated by Compañía Operadora de Gas (COGA), begins in the Amazon rainforest, crosses the Andes Mountains (4850msnm) and finally descends towards the Pacific coast. The PTS has been operating for more than 10 years and it has Natural Gas (NG) and Natural Gas Liquids (NGL) transportation pipelines. The NG pipeline is 888km long which includes two Loops (105km and 18km in the coast and mountain sectors, respectively). NGL pipeline is 557km long.
From the beginning (0 km) to 210 km, the Right of Way (RoW) is located in the geotechnical context of the Amazon rainforest. Then, between km 210 and km 420, the PTS crosses the mountain chain of the Andes. Finally, between km 420 and Km 730 the RoW is located on the Peruvian Pacific coast.
TGP’s operation of the PTS identifies, analyzes and controls the different types of threats that can affect the integrity of the pipelines. The operation is developed according to international standards defined in the Pipeline Integrity Management (PIM) of the operation. Consequently, hazards such as Third Party Damage (TPD), geohazard, external and internal corrosion, among others, are analyzed.
However, associated to the economic growth and development of Peru, there have been some cases where the intervention of a person, community or industrial activity in the surroundings of the RoW has resulted in the level of geohazards are spontaneously modified and activated. Consequently, the degree of stability of the RoW is necessary to analyze the integrity of the NG and NGL pipelines.
This article describes the occurrence of some practical cases where there was a change in the stability of the RoW of the TGP’s PTS triggered by activities related to TPD. It is highlighted that the identification, analysis, definition and execution of mitigation actions are carried out in a transversal way which involves the participation of different operational areas such as: Integral Maintenance, Geotechnics, Integrity, Social Management, among others. All the activities are done with the approach of keeping the balance between community, environment and infrastructure.
Some of the cases considered are: Flood and scour of the RoW triggered by the failure of a water tank in an industrial area, scour of channels due the obstructions and an unstable slope process generated by constructions near the RoW.
Today, the operation develops activities in order to mitigate geohazards generated by TPD. Some of these activities are, among others: Social awareness, technical talks, agreements with industrial and local administration entities, geotechnical maintenance and monitoring. In addition, it is highlighted that all the mentioned mitigation actions are carried out in a transversal manner between different operational areas. Afterward, the collected information is properly saved in the Geographic Information System database.
