Fuel Optimal Thrust Allocation In Dynamic Positioning

This thesis gives a short introduction to the Dynamic Positioning (DP) domain and focuses on developing a fuel optimal thrust allocation algorithm for marine DP vessels with a diesel electric power plant. Obtained data is used to develop a static model for the fuel consumption of a diesel generator, as a function of its produced power. This model is used to formulate a convex Quadratic Programm...

Optimal Thrust Allocation Methods for Dynamic Positioning of Ships

The first Dynamic Positioning (DP) systems emerged in the 1960’s from the need for deep water drilling by the offshore oil and gas industry, as conventional mooring systems, like a jack-up barge or an anchored rig, can only be used in shallow waters. GustoMSC has been developing DP drill ships since the early 1970’s and it is still one of their core businesses. DP systems automatically control ...

Quadratic Programming Thrust Allocation and Management for Dynamic Positioning Ships

To solve the complex thrust allocation problems of dynamic positioning ship with azimuth thrusters, the quadratic programming thrust allocation and management system was built. The power optimal thrust allocation was formulated as a quadratic programming problem by the linear treatments of inequality constraints and the optimal solution could be found in a finite amount of time. And some influe...

Transient power control in dynamic positioning - governor feedforward and dynamic thrust allocation

A thrust allocation algorithm with capability to assist the power management system on a vessel with diesel-electric propulsion has recently been proposed. In the work presented here, the results show that the use of this thrust allocation algorithm produces a signi cant improvement in the stability of the electric bus frequency in the presence of large power load variations, as long as those l...

Thrust - Limited Optimal Three - Dimensional Spacecraft Trajectories

Several optimal three-dimensional orbital transfer problems are solved for thrust-limited spacecrafts using collocation and nonlinear programming techniques. The solutions for full nonlinear equations of motion are obtained where the integrals of the free Keplerian motion in three dimensions are utilized for coasting arcs. In order to limit the solution space, interior-point constraints are use...
