Dynamic Positioning around an alternative control point

Traditionally, the control point (CP) of a dynamically positioned vessel is located around its center of gravity (CoG). However, during offshore operations, other locations, such as the crane tip or gripper position, become more critical due to the load being located there. This thesis proposes shifting the control point from the CoG to an...

Station-keeping in the vicinity of the collinear Lagrange points

In this thesis, the performance of three different station-keeping methods applied to Sun-Earth L2 halo orbits is investigated. In order to evaluate these methods, first a framework for accurate satellite dynamics was developed. This was done by starting off at the Circular Restricted Three Body Problem, and extending that to a more accurate...
