Buoys

The buoy object enables to define any kind of structure that must be part of the model but is not a line. Equivalent loads (drag, inertia, mass, buoyancy) will be used to model the structure.

Each buoy is characterized by a number of data, which can be split as follows.

  • General data : to specify the name of your buoy, the position of the buoy center expressed in the global coordinate system, and whether the buoy is free or linked with another object from your model.

  • Drawing : to define all the geometrical parameters used to display the buoy in the 3D view window.

  • Properties : to define the mechanical and hydrodynamic properties of the buoy.

  • Fairleads/Hang-off points : this defines fairleads and hang-off points linked to the Buoy which can be used to connect other model components. Each fairlead and hang-off point is defined through its coordinates and built-in angle with respect to the Buoy reference point. You may create as many fairleads and hang-off points as desired.

Note

Despite the "fairlead" and "hang-off" terms are generally used to refer to mooring lines connection and riser connection, this does not make any difference there. These points could be thought of as general purpose connection points to which any model component can be linked to.
