what is oil spill boom？

 Oil containment boom is a kind of equipment used to enclose oil and dirt on water surface with underwater floating body with skirt to prevent their diffusion. Portable containment booms are commonly used to prevent the spread of oil pollution in oil spill accidents at sea and ports. It is composed of inflatable floating body, skirt edge, tension band, counterweight chain, and mooring parts. It is fixed around the oily water surface that needs to be fenced with anchors. It can be divided into marine type, offshore type, port type and other types according to the use area, and has corresponding different technical data. When an oil spill accident occurs, the oil spill will spread and drift rapidly under the influence of tide, wind and other external factors, forming a large pollution area. In case of oil spillage in open waters, near shore waters or ports,pvc oil boom shall be arranged in a timely manner, so that the oil spillage in the process of diffusion can be enclosed in a timely manner. Through the pvc boom to drag or narrow the containment area, the Rubber oil boom can be gathered to a smaller area for recovery, which can prevent the spread of oil spillage, and can also increase the thickness of oil film for recovery or other treatment.

Performance characteristics of oil containment boom.

The surface of the oil boom shall be clean, and the PVC coating of the pvc boom shall not fall off or crack; The body wrapping is firmly sewn without cracking, and all parts are torn; The floating boom has a cylindrical structure and is foamed as a whole. The floating body is complete in shape. The floating body is sealed and wrapped with oil resistant materials to prevent oil spillage or loss; Measures shall be taken for metal structures, such as galvanizing and coating, and non-metallic materials shall be made of seawater resistant, weather resistant and oil resistant materials; The Rubberc oil fence can be connected and positioned with the ship or shore by the cable. The surface of the pvc boom is flat and smooth, which is convenient for transportation, towing, cleaning and storage. The operation and maintenance cost is low; The vulnerable parts of the pvc oil fence and the main body of the pvc boom can be repaired in situ, and other accessories can be replaced in situ. The counterweight chain shall be burred, coated with asphalt paint on the surface and surrounded by the wrapping cloth, and shall not be exposed; The drain hole and the tarpaulin ring on the joint are riveted firmly, cracked or skewed; The connectors of the same type of oil interceptors shall have good interchangeability; The normal service life shall not be less than 3 years, and the normal storage life shall not be less than 6 years.

Basic structure of oil containment boom.

The oil containment boom can stably float on the water surface and is used to prevent the spread of oil spill, reduce the area of oil spill, transfer oil spill and floating objects, and protect the water environment. There are many types of oil containment fence with different forms. But the basic structure is composed of floating body, skirt, tension belt, counterweight and joint.

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

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

Tension belt: refers to a long belt component (chain, belt) that can withstand the horizontal tension applied on the pvc boom. It is mainly used to bear the tension generated by wind, wave, tide and drag.

Counterweight: ballast that can make the pvc boom droop and improve its performance. It can make the oil containment boom in an ideal state in the water. It is generally made of steel, lead or water as ballast.

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

Storage and maintenance of oil containment boom.

The storage and maintenance of the oil containment boom is directly related to the rapid oil spill emergency response and the effective implementation of containment operations. In order to ensure rapid response, the storage location of the pvc boom should be as close to the wharf, operation point and sensitive resource protection area as possible, and ensure that the storage location of the pvc boom is convenient for vehicles and ships to enter and exit. For the oil fence stored outdoors, ensure that the storage site is well drained, pay attention to insect pests, moisture-proof, and avoid direct sunlight; When it is stored indoors, it should also pay attention to moisture-proof and ensure good ventilation conditions, and take necessary measures to prevent pests (such as releasing rodenticide) in the storage place according to the situation; The oil containment boom that needs to be folded for storage shall be placed on the partition frame and no other items shall be stacked on it to avoid deformation of the oil containment boom due to excessive pressure. The stacked oil containment boom shall be inspected regularly and the original folding trace shall be avoided when it is folded again; If the oil boom needs to be stored on the reel, it should be avoided that the oil boom is twisted during the winding process, and the oil boom should be unfolded regularly and recycled after inspection. The maintenance of thepvc oil boom mainly refers to the daily maintenance and the maintenance after the recovery operation. The maintenance after the recovery operation is mainly to check whether the oil boom is damaged, whether the accessories are complete or whether they need to be replaced and repaired; Daily maintenance: generally check whether the oil boom is worn, cracked, fiber aged, connector corroded or damaged due to pulling and other loading and unloading reasons, and conduct necessary maintenance and replacement; The pvc oil fence that has been placed in the water area for a long time should also be maintained regularly. Generally, the oil containment boom should be towed to the shore regularly according to the specific situation to remove the marine organisms and other adhesive substances attached to the surface of the oil containment boom; No matter what kind of maintenance and service is carried out, detailed records shall be made and inspection and maintenance items shall be arranged according to the records to ensure that all the contents involved in the oil containment boom can be inspected and maintained generally within a certain period of time, so that the floating boom is always in a good standby state.
