The Natural Gas (NG) and Natural Gas Liquids (NGL) Transport System of Camisea consist of two parallel pipelines. Both pipelines run from the exploitation site at the plant Malvinas located in the Cusco Department and traverse the Peruvian Amazon and Andean region (up to a height of 4,800 m above sea level). The Natural Gas pipeline has a total length of 730 kilometres (Km) and terminates in Lurín situated to the south of Lima. The NG pipeline is divided into three segments with different pipe diameters. The first segment: 210 Km long and 32 inch diameter; the second: segment 310 Km and 24 inch diameter; the third segment: 210 Km and 18 inch diameter. The NGL pipeline is 560 Km long and ends at the Pisco plant. It is divided into two segments with different diameters. The first segment: 455 Km long and 14 inch diameter; the second: segment 105 Km and 10.15 inch diameter. The NG and NGL transport system has been in operation since August 2004. Since then, five failures have occurred. These accidents have lead to leakages. In one case two persons were injured due to a fire. All failures concern the smaller pipeline (NGL). Due to these problems, the Ministry of Energy and Mines of Peru decided to carry out an integral audit on the pipeline system. Germanischer Lloyd has the task to determine whether the Camisea pipeline transportation system has been constructed and commissioned in compliance to the specifications and international norms and standards. The document review activities of the audit team will cover all the phases of the project; design, material and equipment acquisition, construction, testing, commissioning, operation and maintenance. In addition, the work group will perform inspections on site along the pipeline route in order to evaluate specific points considered critical due to their location (geo-hazardous areas). The expert team will also asses the geotechnical mitigation works that are being carried out. The auditor will verify that all equipment installed in the surface stations is in compliance with the specifications. Finally, the causes of the five accidents will be investigated. At the end of the project Germanischer Lloyd will issue a report addressed to the Ministry of Energy and Mines containing a detailed description of the activities, the results and possible mitigation strategies to solve potential problems.
