Description
Wave-induced motions and loads on a moored and articulated multibody offshore structure are investigated through numerical analysis. A coupled mooring-joint-viscous flow solver is employed to account for mooring dynamics, joint restrictions, nonlinear rigid body motions, and viscous flow effects. The study focuses on two modular floating structures (MFSs) connected by a flexible joint, with and without a rotational damper, and positioned using four symmetrical mooring lines. The analyzed responses encompass multibody motions and the associated forces acting in the hinged joints and the mooring lines. The results reveal that the influence of the damper on heave motions is less significant. Notably, the presence of the rotational damper has a noticeable impact on pitch motions between the two hinged MFSs. Introducing a rotational damper on the flexible joint effectively dampens the highly dynamic pitch motions while not imposing additional loads on the flexible joints.
