WAVE DAMPENER FOR FLOATING STRUCTURES

摘要

A dampening device for dampening the vertical wave-induced motion component of a floating structure. A dampener may project as a skirt down below the bottom of the floating structure and includes of a plurality of channels extending substantially horizontally and converge from an inlet to an outlet leading away from the floating structure. When the structure moves downwards water is forced from the underside through the channels and creates a jet effect which acts with dampening effect on the vertical motion of the structure. The dampening device may also be made in the form of an outwardly projecting skirt on the floating structure and consist of a plurality of channels, where a number of first passages extend in a substantially vertical direction and merge into a number of second passages which extend in an at least substantially horizontal direction.
