• Experimental and Numerical Study of the Free Surface Elevation Over the Pontoons of a Semisubmersible Platform in Waves 

      Pessoa, João; Stansberg, Carl Trygve; Fonseca, Nuno; Laranjinha, Manuel (ASME 2018 37th International Conference on Ocean, Offshore and Arctic Engineering - Volume 1: Offshore Technology;OMAE2018-78009, Chapter, 2018-06-25)
      The region over the pontoons, especially in the vicinity of columns, is typically a critical area in terms of upwell when analyzing the air gap of semisubmersible platforms. There is indication that numerical computations ...
    • Investigation of Higher-Harmonic Wave Forces and Ringing Using CFD Simulations 

      Kamath, Arun; Bihs, Hans; Pakozdi, Csaba (ASME 2018 37th International Conference on Ocean, Offshore and Arctic Engineering;Volume 7B: Ocean Engineering;OMAE2018-77925, Chapter, 2018-06-25)
      Typical offshore structures are designed as tension-leg platforms or gravity based structures with cylindrical substructures. The interaction of waves with the vertical cylinders in high sea states can result in a resonant ...
