Modeling Skin Injury from Hot Spills on Clothing
Log, Torgrim (Peer reviewed; Journal article, 2017) -
Modelling breakdown of industrial thermal insulation during fire exposure
Gunnarshaug, Amalie; Log, Torgrim; Log, Maria-Monika Metallinou; Skjold, Trygve (Peer reviewed; Journal article, 2023)The aging of many of the installations in the oil and gas industry may increase the likelihood of loss of containment of flammable substances, which could lead to major accidents. Flame temperatures in a typical hydrocarbon ... -
Numerical Investigation of the Required Quantity of Inert Gas Agents in Fire Suppression Systems
Hu, Xiaoqin; Kraaijeveld, Arjen; Log, Torgrim (Peer reviewed; Journal article, 2020)Inert gas agents have the potential to be widely used in fire suppression systems due to health and safety concerns associated with active chemicals. To suppress fire while minimizing hypoxic effects in an occupied area, ... -
Optical Gas Imaging (OGI) as a Moderator for Interdisciplinary Cooperation, Reduced Emissions and Increased Safety
Log, Torgrim; Pedersen, Wegar Bjerkeli; Moumets, Heike (Journal article; Peer reviewed, 2019)Optical Gas Imaging (OGI) cameras represent an interesting tool for identifying leaking components in hydrocarbon processing and transport systems. They make it possible to see exactly where a leak originates, thereby ... -
Reducing Wooden Structure and Wildland-Urban Interface Fire Disaster Risk through Dynamic Risk Assessment and Management
Log, Torgrim; Vandvik, Vigdis; Velle, Liv Guri; Log, Maria-Monika Metallinou (Peer reviewed; Journal article, 2020)In recent years, severe and deadly wildland-urban interface (WUI) fires have resulted in an increased focus on this particular risk to humans and property, especially in Canada, USA, Australia, and countries in the ... -
Skin temperatures of a pre-cooled wet person exposed to engulfing flames
Log, Torgrim (Journal article; Peer reviewed, 2017)In a television show, a wetted bare-skinned person slid through engulfing kerosene pool fire flames. The 0.74 s flame exposure resulted in pain and light sun burns. The heat and mass transfer involved in this dangerous ... -
Small Scale Hydrocarbon Fire Test Concept
Bjørge, Joachim Søreng; Metallinou, Maria-Monika; Kraaijeveld, Arjen; Log, Torgrim (Journal article; Peer reviewed, 2017)In the oil and gas industry, hydrocarbon process equipment was previously often thermally insulated by applying insulation directly to the metal surface. Fire protective insulation was applied outside the thermal insulation. ... -
Study of Heathland Succession, Prescribed Burning, and Future Perspectives at Kringsjå, Norway
Gjedrem, Anna Marie; Log, Torgrim (Journal article; Peer reviewed, 2020)The coastal heathland of Western Europe, dominated by Calluna vulgaris L., was previously maintained by prescribed-burning and grazing to the extent that the Calluna became anthropogenically adapted to regular burning ... -
Study of Industrial Grade Thermal Insulation as Passive Fire Protection up to 1200 °C
Bjørge, Joachim Søreng; Gunnarshaug, Amalie; Log, Torgrim; Metallinou, Maria-Monika (Journal article; Peer reviewed, 2018)It has recently been demonstrated that 50 mm thick industrial grade thermal insulation may serve as passive fire protection of jet fire exposed thick walled steel distillation columns. The present study investigates the ... -
Study of Industrial Grade Thermal Insulation at Elevated Temperatures
Gunnarshaug, Amalie; Log, Maria-Monika Metallinou; Log, Torgrim (Peer reviewed; Journal article, 2020)Thermal insulation is used for preventing heat losses or heat gains in various applications. In industries that process combustible products, inorganic-materials-based thermal insulation may, if proven sufficiently heat ... -
Tunnel Fire Dynamics as a Function of Longitudinal Ventilation Air Oxygen Content
Khattri, Sanjay Kumar; Log, Torgrim; Kraaijeveld, Arjen (Journal article; Peer reviewed, 2019)Longitudinal ambient air ventilation is the most common methodology for maintaining an amicable environment in tunnels during normal operations while providing an evacuation path during tunnel fire emergencies. The present ... -
Validation of a Predictive Fire Risk Indication Model using Cloud-based Weather Data Services
Stokkenes, Sindre; Strand, Ruben Dobler; Kristensen, Lars Michael; Log, Torgrim (Journal article; Peer reviewed, 2021)The high and dense representation of wooden homes in Norway, combined with periods of dry and cold climate during the winter season resulting in very dry indoor conditions, have historically resulted in severe fires. Thus, ... -
Virtually Fenced Goats for Grazing Fire Prone Juniper in Coastal Norway Wildland–Urban Interface
Log, Torgrim; Gjedrem, Anna Marie; Log, Maria-Monika Metallinou (Peer reviewed; Journal article, 2022)For millennia, the coastal heathlands of Western Europe were managed by regular burning cycles for improved grazing. In recent decades, this practice has generally been neglected. In Norway, the result is accumulation of ...
