Abstract
The article focuses on solving a problem of optimal thrust distribution over the actuators in a ship Dynamic Positioning, according to DNV-ST-0111 standard, Level 1. The classic Quadratic Programming approach is combined with the numerical solusion used to handle the propeller with the rudder constraints in the optimization task and the influence between thrusters and skeg. It is presented as an efficient method of minimizing the power consumption. The resulting tool for performing a Dynamic Positioning capability assessment allows for fast calculations to qualitatively compare different designs. The study has proven that the Quadratic Programming based method gives less optimistic solution in comparison with DNV tool and can be safely applied at an early design stage. Further validation of the tool with the time-domain simulations would contribute to increasing confidence in its application to the daily routine calculations.
