Research on Motion Analysis and Simulation Technology of Double Ship Floating Installation of Large Structures

The offshore platform is developing towards the trend of large-scale, complex and centralized. Compared with the single-ship floating installation, the double-ship floating installation can be applied to the installation of more complex and diversified offshore platforms and can improve the safety of installation. It is the development direction of large-scale offshore platform installation technology. In this paper, the motion analysis and simulation technology of double ship floating installation are deeply studied. Through momentum analysis, load model, and motion model establishment, the kinematics simulation is carried out under the South China Sea working condition, which provides basic kinematics data for double ship floating installation.
