RESPONSE CHARACTERISTICS OF A LONG LIFE TYPE FLOATING OFFSHORE AIRPORT IN WAVES (2ND REPORT: ON THE MOTION AND DEFLECTION IN REGULAR HEAD WAVES)

The paper deals with the deflections and bending moments of a new type floating offshore airport in waves, with emphasis on its deck stiffness and effects of the loss of one unit. The response to regular head waves are studies numerically and verified by experiments. The hydrodynamic forces induced by waves are calculated using a 3D singularity distribution method taking the symmetry of the structure into account. Structural analysis is conducted using the finite element method. The hydroelastic responses, namely deflection and bending moment in waves are determined by combining the two analyses. The influence of deck stiffness on deflection and moment are discussed through a series of calculations and the effects of the loss of one unit is investigated.
