Development of approach for reliability assessment of pipeline network systems

Integrated assessment of failure probability of the district heating network

“…Our previous paper includes a pilot study, however, the scope of that study in [1] was limited to the identification of the most vulnerable pipe section on general statistical failure data, evaluation of the mechanical fracture of the selected pipeline and estimation the consequence of this failure to consumers of the network. However, the integrated deterministic-probabilistic pipe rupture analysis, which is part of methodology described in paper [1], was not performed and its influence on the piping failure probability was not taken into account.…”

“…DH network includes three main parts: (1) water heating source, (2) heating supply and distribution piping, (3) consumer systems, which use the heat [1]. The consequences of loss of heating accidents are especially dangerous during the winter season in countries with harsh winters (e.g.…”

“…The methodology for the assessment of reliability of piping networks, presented in our previous work [1], was taken into account in this paper. Our previous paper includes a pilot study, however, the scope of that study in [1] was limited to the identification of the most vulnerable pipe section on general statistical failure data, evaluation of the mechanical fracture of the selected pipeline and estimation the consequence of this failure to consumers of the network.…”

Safety distance between underground natural gas and water pipeline facilities

“…Several studies have been conducted to increase the reliability of the natural gas piping system by improving the system integrity [1][2][3][4] and extending its service life [5]. With the advancement in pipe manufacturing technology, manufacturing defects can possibly be eliminated once and for all.…”

Non-dimensional correlations on flame height and axial temperature profile of a buoyant turbulent line-source jet fire plume

“…[1][2][3][4] A jet fire can form as a result of the leakage and ignition of hydrocarbon gaseous fuel in case of a broken pipe or safety valve, or similar accidental scenarios. 5 Jet fire can pose such serious adverse impact that its characteristics have received extensive research attentions [5][6][7][8][9][10][11] in the past decades.…”
