Common experience in Europe shows that third party interference is generally the main cause of incidents leadings to a gas leak. Gaz de France performed an important work in order to take into account this incident cause. This work, mainly based upon experimental studies, allowed to characterise pipeline resistence to denting and puncture by excavators. Most of the work was done on behalf of EPRG (European Pipeline Research Group composed of major European pipeline operators and pipe manufacturers), and resulted in simple criteria for dent and puncture resistance covering the whole range of transmission pipelines. The paper presents the main principles of a software called 'PACTOLE' that incorporates the results of this work on third party work interference for pipeline design purposes. 'PACTOLE' aims at checking that the pipeline resists to different scenarios of aggression by an excavator. The defect stability criteria used in this context are recalled. The paper presents also 'PACTOLE''s functionality and interface. A typical case of implementation of this software is also detailed. Finally, perspectives of further development are indicated.
