Abstract

In the deepwater region, wave and current coexist simultaneously. The presence of currents in the water body alters the form of wave profile and characteristics. This paper presents the experimental study of the dynamic responses of the classic and truss spars subjected to random wave and current. The JONSWAP Spectrum was used to generate the random wave. The responses of the structures due to random wave and current in terms of Response Amplitude Operators (RAO) in surge, heave and pitch were determined and presented. Results showed that the effect of the existence of current together with wave in the water body caused significant increases in the dynamic responses of the structures. Keywords: Wave-­current interaction;; Spar platforms;; Numerical analysis;; Model tests;; Wave basin;; Response Amplitude Operator (RAO)
