    • Investigating a Simplified Model for Moonpool Piston Mode Response in Irregular Waves 

      Ommani, Babak; Kristiansen, Trygve; Berget, Kjetil (ASME digital collection;OMAE2018-78352, Chapter, 2018-06-25)
      Estimating moonpool piston mode response at resonance is important for operation safety. This is a difficult task, in particular, due to nonlinear nature of the moonpool response connected to the damping imposed by the ...

    • A Physical-Based Damping Model of Gap and Moonpool Resonance in WAMIT 

      Ravinthrakumar, Senthuran; Ommani, Babak; Kristiansen, Trygve; Olimb, Idunn; Lyngvær, Bernt Karsten (Chapter; Peer reviewed, 2022)
      An engineering model to estimate and incorporate quadratic damping of the piston-mode moonpool responses in the proximity of the piston mode period is proposed. The model provides a physical-based equivalent linearized ...
