ON STRUCTURAL RESPONSE ANALYSIS OF SEMI-SUBMERSIBLE OFFSHORE STRUCTURES IN WAVES

Recently, as semi-submersible offshore structures advance into deeper and rougher waters for operation, the design conditions have become severer requiring structural response analysis in very high non-linear waves. From this viewpoint, this paper presents an approximate response analysis method for the semi-submersible offshore structures in waves based on the finite amplitude wave theory and introduce the results of a series of tank tests for verifying the accuracy in computation and its applicability to practical problems. Finally, the accuracy in computation and applicability of the computer program based on the finite and small amplitude wave theories are discussed by comparing with the results of the above tank tests.
