Reasons for using containment booms Oil Containment/Concentration Deflection Protection
Basic Boom Usage Booms can be used in two ways: Static Mobile
Basic Boom Usage Static (anchored) Constrain the spread of the spill
Basic Boom Usage Static (anchored) Contain and concentrate the spill so as to aid recovery
Basic Boom Usage Static (anchored) Divert the oil towards areas better suited for its recovery from the water surface
Basic Boom Usage Static (anchored) Protection of sensitive areas
Basic Boom Usage Mobile Contain and concentrate the spill so as to aid recovery

Key Parameters of Booms Freeboard Draught Buoyancy ratio
Boom Types - Curtain Booms Consist of an air or solid flotation chamber and a continuous underwater section hanging down.

Boom Types Summary Curtain Booms Flotation member filled with air, inert gas, solid foam or granulated foam Flexible skirt which can move independently of flotation member Buoyancy ratio between 5:1 20:1 Air filled booms: easy to clean but slower to deploy than solid booms Storage: small for air filled; large for solid foam filled booms
Boom Types - Fence Booms Solid Float Ballast
Boom Types - Fence Booms Consist of an air or solid flotation chamber and a continuous underwater section hanging down.
Boom Types - Fence Booms
Boom Types - Fence Booms
Boom Types - Fence Booms Types Centre Line Flotation Member Low cost; easy to operate; but can easily bend over due to low roll stiffness Outboard Flotation Member Outboard floats increase roll stiffness and are more stable External Tension Line Increased performance in strong currents; can be complicated to deploy and recover

Boom Types Beach Sealing Boom
Boom Types Summary Beach Sealing Boom Specially designed to keep the oil in the intertidal zone Unique cannot be replaced by other boom types Must be handled with care to prevent tearing the bottom Can be easily connected to containment booms
