초록

The dynamic response characteristics with flexibility variations are examined for presenting the basic data for design of Tension Leg Platforms(TLPs)in waves. A numerical approach is based on the dynamic response analysis theory, in which the superstructure of TLPs is assumed flexible instead of the rigid body assumption used in two-step analysis method. The hydrodynamic interactions among TLP members, such as columns and pontoons are not included in the motion and structural analyse. The equations of motion of a whole structure are formulated using element-fixed coordinate systems which have the origin at the node of the each hull element.
