Freeboard: the minimum vertical height above the water line of the oil containment fence. It is used to prevent or reduce spill oil from splashing over the oil fence.
Draft: the minimum vertical depth of the surface layer below the water line of the floating boom.
Height: the sum of freeboard and draft of oil boom.
Total height: the maximum vertical height of the oil boom.
Weight: the total weight of a fully assembled section of the oil boom including the oil containment boom joint.
Total floating weight ratio: the ratio of the total buoyancy to the total weight of the boom, referred to as the floating weight ratio. The high floating weight ratio indicates that the oil containment boom has a strong ability to recover its floating state after being flooded. This self recovery ability of the oil boom is called wave following property. The higher the floating weight ratio, the stronger the self recovery ability and the better the wave following property.
Tensile strength: the breaking force when the oil containment boom is broken under tension.
