Numerical investigation of dynamic behaviour of single and two hinged articulated towers in random sea

The present paper deals with comparative studies on hydrodynamic behaviour of Single and two hinged articulated towers in Random sea. dynamic is investigated under long crested Uni directional random sea the wave force calculations are performed using Modified Morison equation. A visual based C + program developed to evaluate response by taking into account non linearities like time variation submergence, instantaneous tower orientation loading. Finally, equations motion solved New Mark integration scheme followed Fast Fourier transform obtain Power spectral densities. From results, it observed that presence intermediate hinges reduced energy coming Two indicating its significance over towers.
