Abstract
In order to provide a containment boom capable of functioning as a barrier for certainly preventing the containment of oil spill in no concern to momentary violent movements of waves and currents, the containment boom comprises a plurality of float units and a coupling portion by which adjacent float units are coupled to one another. Each of the float units comprises a housing having an oil shielding surface perpendicular to sea level, a float portion having a buoyant force, and a plummet portion positioned under the float portion. In addition, the float portion and the plummet portion are adjusted so as to locate a water line to approximate middle position of vertical length of the oil shielding surface. Furthermore, the coupling portion is a flexible coupling portion for varying a relative position between the adjacent float units.
Claims5
A containment boom comprising a plurality of float units and a coupling portion by which adjacent float units are coupled to one another wherein:
- each of said float units comprises a housing having an oil shielding surface perpendicular to sea level, a float portion having a buoyant force, and a plummet portion positioned under said float portion;
- said float portion and said plummet portion being adjusted so as to locate a water line to approximate middle position of vertical length of said oil shielding surface;
- said coupling portion being a flexible coupling portion for varying a relative position between the adjacent float units;
- wherein said coupling portion comprises a rail member:
- and
- said containment boom includes a position stabilizing member for permitting and limiting the relative position of the adjacent float units in upward and downward directions.
