    • Boarding Control System - for Improved Accessibility to Offshore Wind Turbines 

      Auestad, Øyvind Fidje; Perez, Tristan; Gravdahl, Jan Tommy; Sørensen, Asgeir Johan; Espeland, Trygve H. (Journal article; Peer reviewed, 2015)
      This paper considers the dynamic modelling and motion control of a Surface Effect Ship (SES) for safer transfer of personnel and equipment from vessel to-and-from an offshore wind-turbine. Such a vessel is a key enabling ...

    • Motion Compensation System for a Free Floating Surface Effect Ship 

      Auestad, Øyvind Fidje; Gravdahl, Jan Tommy; Sørensen, Asgeir Johan; Espeland, Trygve H. (Chapter, 2014)
      This paper deals with vertical motion compensation, or motion damping, on a freefloating Surface Effect Ship (SES) at zero speed. The Motion Compensation System (MCS) works by varying the air cushion pressure of a Surface ...
