Parametric study on the deep ocean space-rocket launching triceratops.

This paper conducts numerical studies on the response of a deep ocean rocket launching triceratops for five rocket launching cases at a water depth of 1055 m. It is observed that the relative response of the structure increases with the increase in the thrust force and moments; relative surge response of deck and buoyant legs are marginal compared to heave and pitch due to the ball and socket joint connecting the deck and the buoyant legs. Hence, the novel response characteristics offered by the ball joints are utilized for launching large rockets. As the launch varies from small to huge rockets, the variation in the tether tension is also increased. The Quadra-response spectrum for the launch shows the importance of the resonance condition under rocket launch. Parametric studies of varying sea states along with light air, moderate breeze, and strong breeze conditions were selected for the study. The worst scenario for a deck is observed under a strong breeze when large rockets are launched. The numerical analysis shows that the relative displacements due to the rocket launch depend on the environmental parameters and thus emphasize a holistic design approach incorporating the combined effects of wave, wind, and rocket. • Offshore triceratops is an ideal option for space launches. • Partial isolation inducted by ball joints enables desirable dynamic characteristics for such operations. • Ball joints restrain the transfer of impulse force to the legs during space launch. • Operational stability of offshore triceratops during rocket launch is verified.
