Abstract

Vessel, preferably for petroleum processing and storage, with carrying capacity mainly comprised by one single hull, with a main deck (1). The new and inventive feature is comprised by at least one, mainly horizontally shaped dampening device (1) reaching out from either side of the hull (3) under the water line, extending preferably along the entire length of the vessel. The purpose with, and the effect of the dampening device (2) is to dampen the rolling movements of the vessel, and also for pitch and heave movements. In the preferred embodiment the dampening device (2) has a plurality of vertical apertures (22) allowing limited water through flow. The dampening device (2) with the openings (22) act as a mechanical filter which to a large degree dampens the rolling, pitching and heave movements and let pass long-wave roll, pitch and heave movements, but with dampened amplitude.
