Investigation of systems for the detection of third-party impact on high-pressure gas pipelines© DIV Deutscher Industrieverlag GmbH (10/2011)
Construction activities may cause damage to pipelines and thus present a potential risk to pipeline integrity. Existing organizational measures such as regular pipeline patrols by vehicle or pipeline surveys by plane as well as rules and regulations to be observed by outside companies performing work in a pipelineās right-of-way help to reduce this risk effectively. Appropriate technical monitoring methods are an additional means to protect pipelines against external influences. Under a comprehensive research project DVGW examined new methods for monitoring high-pressure gas pipelines and preventing third-party impact (TPI). The project focused on the TPI systems available on the market for continuous pipeline monitoring to ensure prompt detection of thirdparty activity. The TPI systems considered most suitable for the purpose were selected and tested in the field. The project also included an evaluation of the systems tested and recommendations for action.
Design of a pipeline rehabilitation including the modern approach of PIMS and RMS© DIV Deutscher Industrieverlag GmbH (10/2011)
An Eastern European pipeline operator was facing challenges regarding the integrity of an existing pipeline system in which several leaks and accidents had already occurred. In order to render the system āFit for Purposeā a number of tests and rehabilitation possibilities were analysed by ILF Consulting Engineers and an optimum rehabilitation concept defined. The actual condition of the pipeline system was first assessed with respect to current standards, resulting in recommendations for the replacement or rehabilitation of some pipeline sections. The future integrity and safety of the pipeline system will, however, depend on the continuing implementation of āRisk Managementā and āPipeline Integrity Managementā systems.
