    • 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 ...

    • Industrial Thermal Insulation Properties above Sintering Temperatures 

      Gunnarshaug, Amalie; Metallinou, Maria-Monika; Log, Torgrim (Journal article; Peer reviewed, 2021)
      Processing highly flammable products, the oil and gas (O&G) industry can experience major explosions and fires, which may expose pressurized equipment to high thermal loads. In 2020, oil fires occurred at two Norwegian O&G ...

    • Influence of Acetone and Sodium Chloride Additives on Cooling Efficiency of Water Droplets Impinging onto Hot Metal Surfaces 

      Bjørge, Joachim Søreng; Bjørkheim, Svein Arne; Log, Maria-Monika Metallinou; Log, Torgrim; Frette, Øyvind (Peer reviewed; Journal article, 2019-06-19)
      In the present work, the cooling efficiency of water droplets falling onto hot aluminum and stainless steel discs from heights of 12.5 cm, 25 cm, 50 cm and 100 cm, corresponding to speeds of 1.5 m/s, 2.2 m/s, 3.1 m/s and ...

    • Method for measuring cooling efficiency ofwater droplets impinging onto hot metal discs 

      Bjørge, Joachim Søreng; Metallinou, Maria-Monika; Log, Torgrim; Frette, Øyvind (Peer reviewed; Journal article, 2018-06-09)
      The present work outlines a method for measuring the cooling efficiency of droplets impinging onto hot metal discs in the temperature range of 85 °C to 400 °C, i.e., covering the boiling regimes experienced when applying ...

    • Modelling breakdown of industrial thermal insulation during fire exposure 

      Gunnarshaug, Amalie; Log, Torgrim; Log, Maria-Monika Metallinou; Skjold, Trygve (Journal article; Peer reviewed, 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 ...

    • 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 (Journal article; Peer reviewed, 2020-03-18)
      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 ...

    • Small Scale Hydrocarbon Fire Test Concept 

      Bjørge, Joachim Søreng; Metallinou, Maria-Monika; Kraaijeveld, Arjen; Log, Torgrim (Peer reviewed; Journal article, 2017-11-14)
      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 Industrial Grade Thermal Insulation at Elevated Temperatures 

      Gunnarshaug, Amalie; Log, Torgrim; Metallinou, Maria Monika (Journal article; Peer reviewed, 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 ...
