Abstract :
The mobile mooring system of ships usually consists of dozen of anchor windlasses, and it is an important question how these windlasses coordinate to fulfill the commanded tension input. The tension allocation of mobile mooring system with eight anchor windlasses is formulated in this study. The tension allocation problem is defined as an optimization problem and an active set method is adopted to find the optimized solutions. The simulation results show that the mobile mooring system is able to allocate dynamically the tension of each anchor windlass, and keep the ship at the desired position under sea wind.
