    In the design of a floating production, storage and offloading (FPSO) unit and a floating offshore wind turbine, it is important to evaluate dynamical behavior of systems with floating structures and devices connected by mooring lines and riser cables for carrying resources, supplying energy and so on.
    This study focuses on a multi-body system with huge degrees of freedom and develops a model applicable to the parallel computation and the state estimation techniques. The present model introduces an incremental description of rotation of the body, which ensures a computation accuracy regarding a time step size. In addition, the local Lagrange multiplier method is employed for development of the model applicable to the parallel computation technique. Then, the proposed method is validated by comparisons with experimental results and a conventional method.

    The flow-induced vibration for flexible thin plates and membranes surrounded by a fluid flow is an important engineering topic in the state-of-the-art manufacturing technology for the functional flexible membranous products, such as rollable solar panels, LED panels and so on.
    We proposed an alternative analytical method for a description of the fluid-structure interaction problem based on the canonical theory for the constrained system. The proposed method is inspired by a numerical approach for multi-body system dynamics. In addition, this study developed a stability analysis method for a prediction of the flow-induced vibration. Then, the boundary condition for pressure, widely used in this problem, was verified by prospective vibration behavior. The proposed method was validated by comparing with results in the literatures.
