Abstract: In order to maintain the fixed position, the thrust allocator needs to determine the magnitude and direction of the thrust required for each azimuth thruster to create a force and moment equilibrium. However, there exist multiple solutions for the thrust-allocation problem because, the oil rig platform is overactuated and the azimuth thrusters fitted at oil rig platform?s pontoon level can produce forces in different directions. Therefore, the solution to the thrust allocation problem can be found by formulating it as an optimization problem, with an objective to minimize power consumption, drag, tear/wear and other costs related the control variables, subjected to the constraints such as thruster position constraints and other operational constraints. In this thesis, different thrust allocation approaches have been discussed.
