WebJan 12, 2012 · Theory, 6D Buoy Theory 196 w Warning: This lumped buoy surface-piercing model is not realistic or accurate – OrcaFlexdoes not have enough geometry information for lumped buoys to model the surface-piercing accurately. It is just a simple way to give a buoyancy force, wetted volume and centre of wetted volume that vary in the Three types of 6D buoy are available: lumped buoys, spar buoys and towed fish. These share some common data, but they differ in the ways in which the buoy geometry is defined and the fluid loads and surface-piercing effects are calculated. These differences are summarised below. Lumped buoys See more These are the simplest type, and have an abstract geometry: their shape is not defined. This necessarily restricts the accuracy with which interactions with the water … See more These are intended for modelling axisymmetric buoys whose axis is normally vertical and where surface-piercing effects are important (such as for a CALM buoy). … See more These are intended for modelling bodies whose principal axis is normally horizontal. Towed fish are identical to spar buoys except that, for convenience, the stack of … See more
