This is a cylinder with a varying diameter over its height, representing the jacket structure. The second method uses an equivalent stick model. This flow is used to determine the drag and inertia loads exerted by the water. Current, waves and the jacket's motions result into a flow perpendicular to the member center lines. The first calculation method uses bins along the length of all jacket members. Both of these methods rely on the Morison equations. A 2D numerical model of a jacket type support structure installation in the side-lead direction has been developed in Python with two ways of calculating the forcing. This need brings the research objective of this thesis to "Development a parametrized motion prediction model for jacket installation.". This repetitive nature leads to a need for a better understanding of the behaviour during installation of various jacket geometries. Toornstra, Benjamin (graduation committee)Ĭontrary to a one-off jacket installation where a contractor can wait for favourable weather conditions, the installation of support structures for offshore wind turbines is of repetitive nature.
