    • Marine icing observed on KV Nordkapp during a cold air outbreak with a developing polar low in the Barents sea. 

      Samuelsen, Eirik Mikal; Løset, Sveinung; Edvardsen, Kåre (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06)
      Marine icing is a phenomenon that may occur for temperatures below subfreezing where sea spray either is lofted from the sea surface or being generated by waves interacting with a ship or a structure. On a voyage from Tromsø to the waters east of Bjørnøya late February 1987, the Norwegian Coast Guard vessel KV Nordkapp experienced heavy icing due to a polar low that raged over these waters during ...

    • Sea-spray measurement tools and technique employed in marine icing field expeditions: A critical literature review and assessment using CFD simulations 

      Dhar, Sushmit; Naseri, Masoud; Khawaja, Hassan Abbas; Samuelsen, Eirik Mikal; Edvardsen, Kåre; Barabady, Javad (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-24)
      Sea-spray icing resulting from sea spray droplets accreting on exposed surfaces poses a significant safety concern for vessels and marine structures operating in cold climate regions. One of the key parameters determining the amount of ice accretion is the quantity of incoming sea spray, which eventually comes in contact with the structure in the presence of brine film freezing temperature. Hence, ...

    • Spray Icing on ONEGA Vessel- A Comparison of Liquid Water Content Expressions 

      Dhar, Sushmit; Samuelsen, Eirik Mikal; Naseri, Masoud; Aarsæther, Karl Gunnar; Edvardsen, Kåre (Journal article; Tidsskriftartikkel, 2022)
      The hazards associated with ice accretion primarily due to impinging freezing sea spray on ship structures are considered among serious safety concerns for ships operating in the colder regions. An accurate sea-spray icing-estimation model to evaluate the ice accumulation during operations in these regions can make marine operations safer. The accuracy of the present icing models for estimating icing ...

    • Unprecedented Vessel-Icing Climatology based on Spray-Icing Modelling and Reanalysis Data: A Risk-Based Decision-Making Input for Arctic Offshore Industries 

      Naseri, Masoud; Samuelsen, Eirik Mikal (Journal article; Peer reviewed, 2019-04-11)
      Marine icing is considered a major concern for vessels operating in the Arctic Ocean. Interaction between vessels and waves is the major source of sea spray that, under certain conditions, can lead to ice accretion on the vessels and thus create hazardous situations. Various models have been developed for the estimation of ice accretion rate using meteorological and oceanographic parameters. Various ...
