Description
Oil is less dense than water, giving it buoyant properties. That means when oil releases into the ocean, it naturally floats to the surface rather than sink to the bottom or hover in the middle. This makes containment booms highly effective at creating a barrier that traps oil in a thick layer on the water’s surface. Any oil that releases into water will travel to the surface where booms are waiting to contain it. With that said, oil spreads fast on the surface when it’s not contained. The longer first responders wait to deploy oil spill containment booms around the perimeter, the larger the spill area will become. This is why it’s important for response crews to work fast during the initial hours of an oil spill. After surveying the situation, first res
ponders will layout a perimeter of booms to contain the oil. The goal when dealing with a spill is to create a full circle of booms with no openings or gaps. Once the boom circle is complete, the oil will remain trapped inside where it can no longer continue to spread.
Oil booms reduce the possibility of pollutiion shorelines, rivers, and oceans, but also allow for an easy recovery. During spill responses, sensitive locations are threatened by oil slick, but these areas can be protected by equipment. Oil containment boom are designed and manufactured using plastic, metal, or other materials to slow the spread of oil and keep it contained. Durainflate manufactures oil spill containment booms for all applications and conditions, including conventional booms, air-inflated boom, self-inflating boom, and permanent boom.
Booms feature several heavy duty components to stand up to tough marine environments. Impermeable PVC is a high strength fabric common to most booms, often a bright yellow or orange for high visibility. It acts as a skin around the foam flotation chamber which sits above the water surface (the freeboard). Boom floats provide buoyancy and come in different shapes, including flat rectangular (fence booms) or round cylinders (curtain booms).
PVC also forms the skirt that sits in the water and acts as the barrier wall beneath the surface. A ballast chain at the base of the skirt provides weight and bottom tension. This section is known as the boom’s draft.
Slide connectors and pins run down the total height of the boom, linking sections together to form the enclosure shape. Some booms use a tension cable that runs along the top of the freeboard, to provide extra strength in rough water conditions.
