Abstract

Oil and gas pipeline accidents can lead to severe consequences such as explosions, injuries, and fatalities. In this thesis, onshore and offshore hazardous liquid and gas pipeline accidents that occurred between 2010 and 2017 are investigated. The main objective is to estimate failure rates and analyze how failure consequences are related to pipeline design. The results help the industry to minimize risks associated with pipelines and improve emergency response planning and accident management systems for new and existing pipelines. Linear and logistic regression and Bayesian rate estimation are applied for the data analyses. Onshore hazardous liquid gathering pipelines have the largest failure rate of 3.37E-03 accidents per km per year. The analysis results shows that ignition, injury, and fatality probabilities increase with diameter.

The University of Calgary, located in the heart of Southern Alberta, both acknowledges and pays tribute to the traditional territories of the peoples of Treaty 7, which include the Blackfoot Confederacy (comprised of the Siksika, the Piikani, and the Kainai First Nations), the Tsuut’ina First Nation, and the Stoney Nakoda (including Chiniki, Bearspaw, and Goodstoney First Nations). The City of Calgary is also home to the Métis Nation of Alberta (Districts 5 and 6).

The University of Calgary is situated on land Northwest of where the Bow River meets the Elbow River, a site traditionally known as Moh’kins’tsis to the Blackfoot, Wîchîspa to the Stoney Nakoda, and Guts’ists’i to the Tsuut’ina. On this land and in this place we strive to learn together, walk together, and grow together “in a good way.”
