    • Experimental Investigation of Deicing with Seawater 

      Sæterdal, Ane Solbakken; Visich, Aleksandra; Deshpande, Sujay; Sundsbø, Per-Arne (Chapter; Bokkapittel, 2023-06-19)
      Increased traffic and interest in arctic regions necessitate measures to ensure the safety and functionality of vessels. Sea-spray icing is one of the significant hazards for small- and medium-sized vessels in polar waters. Ice cover can restrict access to essential parts of a vessel and compromise its stability. Existing deicing measures, such as heat or chemical application and manual ice removal, ...

    • Experiments With Sea Spray Icing: Investigation of Icing Rates 

      Deshpande, Sujay; Sæterdal, Ane Solbakken; Sundsbø, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-11)
      Sea spray icing on ships and marine structures depends on a complex correlation between metocean parameters and vessel characteristics. Sea spray icing rates have mostly been investigated and given as a function of general metocean parameters. The existing models suffer from the lack of experimental data. More experimental data are required for better prediction models and understanding of the icing ...

    • Ship resistance analysis using CFD simulations in Flow-3D 

      Deshpande, Sujay; Sundsbø, Per-Arne; Das, Subhashis (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-19)
      While designing the power requirements of a ship, the most important factor to be considered is the ship resistance, or the sea drag forces acting on the ship. It is important to have an estimate of the ship resistance while designing the propulsion system since the power required to overcome the sea drag forces contribute to ‘losses’ in the propulsion system. There are three main methods to calculate ...
