title = "Numerical simulation for truncated model tests of deepwater semi-submersible platform with viscous damper compensated system in mooring lines",
abstract = "Through a truncated model test of semi-submersible platform with the static equivalent mooring system, the availability of numerical simulation in the motions calculation of semi-submersible platform are validated and the results show the mooring damping may contribute significantly to the total damping of deepwater floating platform in the low frequency range. The viscous damper is designed to simulate the contribution of mooring damping. The dissipated energy by a mooring line from the floating platform as a result of its oscillation is applied to calculate the mooring-induced damping. The value difference of mooring induced damping between the truncated and full-depth mooring line is linearized to provide parameter for the design of viscous damper. The viscous damper is added to the numerical simulation of the motions calculation of semi-submersible platform with the truncated mooring line. Finally, the results are compared with motions calculation of semi-submersible platform with the full-depth mooring line.",
