Dynamic motion decoupling and damping is achieved with the use of mass, added mass, buoyancy, submerged weight and drag in arbitrary locations on catenary and/or tensioned lines. The original line configuration may or may not be modified. Novel, drag and added mass enhancing devices effective in all directions can be used to increase the suppression effectiveness and/or in order to reduce the number of devices used. This invention is suitable for use on new designs and it is also suitable for retrofitting on existing, already installed lines. |
