Abstract :
Developed mooring unit, the MoorMaster, which replaces conventional
mooring lines is addressed here. The hydraulics of the system have a strong
deducting effects on the motions of the moored ship. MoorMaster act in two
different states. In first state; mechanism controls transfer mechanism to
suitable position and joint with ship. Second state is passive mechanism state
that lock in last position and the controller is passive so that springs and
dampers appliance in mechanism carry passively apply forces from ship to
mechanism. First; we defined state variables and According to the Lagrange
equations, dynamics model of MoorMaster is extracted using Matlab
Toolboxes and dynamics numerical simulations will be done. Then design a
Controller to control the mechanism to stick to the vessel’s body. Second
state; investigate the interaction forces/moments in between the moored ship
and the mechanism. have considered the simplest case, where the ship is
located just under the MoorMaster force. Ship motion equations solved using
Lagrange equations. and then design a controller that gives the ability to
MoorMaster which exert forces and torques suitable in the freedom direction,
per ship behavior. The results are given in a series of figures.
