Oil containment boom refers to a kind of equipment that surrounds the oil and dirt on the water surface with a floating body with skirt under the water to prevent its diffusion. Portable booms are commonly used to stop the spread of oil pollution in oil spills at sea and ports. It is composed of inflatable floating body, skirt, tension belt, counterweight chain and anchor parts. It is fixed around the oily water surface that needs to be fenced with anchor. It can be divided into marine type, offshore type, port type and other types according to the use area, and has corresponding products. PVC oil containment boom of hopetopway ship wharf is an equipment to prevent oil spill pollution in water area. To prevent oil spill pollution, we must first prevent the spread of oil spill. At present, oil barriers are widely used to intercept oil spill. In addition to intercepting the spilled oil, the oil barrier can also guide the spilled oil and concentrate it as much as possible for further recovery and treatment.

Basic structure of oil containment boom.

Oil containment boom: the equipment that can float stably on the water surface, which is used to prevent the diffusion of oil spill in the water area, reduce the oil spill area, transfer oil spill and floating debris, and protect the water environment is called oil containment boom. There are many kinds and forms of oil booms. But the basic structure is composed of floating body, skirt, tension belt, counterweight and joint.

▲ Floating body: the part that provides buoyancy for the oil containment boom. Its function is to use air or buoyancy materials to provide buoyancy for the oil boom, so that the oil boom can float on the water. The floating body can be placed inside or outside the surface of the oil containment boom.

▲ Skirt: refers to the continuous part of the oil containment boom below the floating body. Its function is to prevent or reduce the escape of oil from under the oil boom.

▲ Tension belt: refers to the long belt component (chain, belt) that can bear the horizontal tension applied on the oil boom. It is mainly used to bear the tension caused by wind, wave, tide and towing.

▲ Counterweight: ballast that enables the oil containment boom to sag and improve the performance of the oil containment boom, which can make the oil containment boom in an ideal state in water. Generally, it is made of steel and lead materials, or water is used as ballast.

▲ Joint: a device permanently attached to the oil containment boom to connect each section of the oil containment boom or other auxiliary facilities.

Oil spill diversion of oil containment boom.

After an oil spill accident occurs, the spilled oil will drift and spread freely under the action of external factors. In order to facilitate the recovery operation or to dredge the spilled oil to the designated place, especially in the area with rapid flow in the river or near the shore, in order to effectively control the flow direction of the spilled oil, facilitate the recovery or prevent the spilled oil from entering the sensitive area, the oil containment boom is usually used to set external defense according to the set angle. There are generally two situations for oil spill diversion. One is to arrange the oil containment boom for a long time, which is generally arranged at the water intake and power plant;

Another situation is to arrange oil containment booms near reefs, mainly in case of oil spill, temporarily arrange oil containment booms according to specific conditions to realize oil spill diversion and lead the oil spill to areas that are easy to recover or other non sensitive resources.

Delivery of oil containment boom.

When the oil containment boom is put into the water from the shore or ship, the tug shall cooperate or the ship shall ride against the current, and it shall be put into the water section by section to avoid disturbance. The oil containment boom shall be sorted out before being put into operation without twisting. Pay attention to the direction when putting in and do not twist after dropping, otherwise it is difficult to straighten it in the water.

When throwing or recovering the oil containment boom into the water, the oil containment boom is easy to be damaged by the shore and ship. For example, it is safe and labor-saving to put it in the convex corner with rollers and chutes.
