Bunker Booms are used on land-to-water transfers, or mid-stream transfers of fuel applications. Usually installed in pairs, at an appropriate distance on each side of the transfer hose, Bunker Booms create a contained area at the point of transfer. Bunker Booms are fitted with fiberglass longitudinal battens that flex like a spring. The end plates are fitted with stiff gasket material to create a seal against the vessel(s) and the dock. The Bunker Boom will spring open with pressure to seal and contact the vessel and dock and create a contained area. If oil is spilled in this area, it will be contained in smaller area than if the entire vessel were surrounded.
