A Common Risk Classification Concept for Safety Related Gas Leaks and Fugitive Emissions?
Log, Torgrim; Pedersen, Wegar Bjerkeli (Journal article; Peer reviewed, 2019)Gas leaks in the oil and gas industry represent a safety risk as they, if ignited, may result in severe fires and/or explosions. Unignited, they have environmental impacts. This is particularly the case for methane leaks ... -
Analysis of a Costly Fiberglass-Polyester Air Filter Fire
Log, Torgrim; Gunnarshaug, Amalie (Journal article; Peer reviewed, 2022)In September 2020, a fire at a liquefied natural gas (LNG) plant in the Arctic areas of Norway received national attention. In an unengaged air intake, the heat exchanger designed to prevent ice damage during production ... -
Analysis of a High‐Voltage Room Quasi‐Smoke Gas Explosion
Bakka, Marit Sigfrid; Handal, Erling Kristian; Log, Torgrim (Peer reviewed; Journal article, 2020)During an air separation unit shut-down in a methanol production plant, a stop signal was sent to the control cabinet of a synchronous motor for a booster compressor. The control cabinet stopped magnetizing the rotor, while ... -
Analysis of Expected Skin Burns from Accepted Process Flare Heat Radiation Levels to Public Passersby
Log, Torgrim (Peer reviewed; Journal article, 2021)Hot flaring, even from quite high flare stacks, may result in significant heat radiation outside a facility to, e.g., public roads where random passersby may be exposed. The present study suggests a novel method for analyzing ... -

We evaluate the performance of 10 available state-of-the-art ... -
Cold Climate Structural Fire Danger Rating System?
Metallinou, Maria-Monika; Log, Torgrim (Peer reviewed; Journal article, 2018) -
A Cold Climate Wooden Home and Conflagration Danger Index: Justification and Practicability for Norwegian Conditions
Strand, Ruben Dobler; Log, Torgrim (Peer reviewed; Journal article, 2023)The vast majority of fire-related deaths occur in residential buildings. Until recently, the fire risk for these buildings was only considered through static risk assessments or period-based assessments applying to certain ... -

Experience gained from 15 years of fire protection plans for Nordic wooden towns in Norway
Kristoffersen, Martin; Log, Torgrim (Peer reviewed; Journal article, 2022)There is a genuine will to protect Nordic wooden towns in Norway, as they are considered national heritage and an important part of the urban identity. The fire protection of wooden heritage towns is an ongoing cooperation ... -
A Fire Revealing Coastal Norway’s Wildland–Urban Interface Challenges and Possible Low-Cost Sustainable Solutions
Log, Torgrim; Gjedrem, Anna Marie (Peer reviewed; Journal article, 2022)The Calluna vulgaris L. that dominated coastal heathlands of Western Europe were for millennia managed by regular burning cycles for improved grazing. Most places in Norway this practice has, however, been neglected over ... -
Fire Risk Prediction Using Cloud-based Weather Data Services
Strand, Ruben Dobler; Stokkenes, Sindre; Kristensen, Lars Michael; Log, Torgrim (Peer reviewed; Journal article, 2021)Dry and cold winter seasons result in very dry indoor conditions and have historically contributed to severe fires in the high and dense representation of wooden homes in Norway. The fire in Lærdalsøyri, January 2014, is ... -
