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
