Oil industry Oil boom fabric

What is  Oil boom fabric ? What is the basic structure of the PVC oil boom fabrics in the oil industry? What are the performance characteristics of Oil boom fabric ?

Oil fence is a kind of equipment that surrounds oil and dirt on the water surface by floating body with skirt under the water to prevent its diffusion. Portable booms are often used to prevent the spread of oil in oil spills at sea and in ports. It is composed of inflatable floating body, skirt, tension belt, counterweight chain and anchor pieces, etc., which are anchored around the oil pollution water surface to be enclosed. According to the use area, it can be divided into Marine type, offshore type, port type and other types, with corresponding different technical data.

Basic structure

Can float on the water surface stably, used in the water to prevent the spread of oil spill, reduce the oil spill area, transfer the oil spill and floating objects, protect the water environment of the equipment called oil boom. There are many types of booms in different forms. But the basic structure is made up of float body, skirt body, tension band, counterweight and joint.

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

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

Tension band: a long band member (chain, strap) capable of withstanding the horizontal tension applied to the oil boom.It is mainly used to withstand the pull of wind, waves, currents and tow.

Counterweight: ballast that makes the oil boom sag and improves the performance of the oil boom. It can make the oil boom in an ideal state in the water. Generally steel, lead material, or the use of water as ballast.

Connector: A device permanently attached to the boom and used to connect each boom or other auxiliary device.

Performance index

The performance indicators of the boom generally refer to the freeboard, draft, height, total height, weight, total buoyancy, float weight ratio and tensile strength of the boom.

Freeboard: Minimum vertical height above the waterline of the boom. Used to prevent or reduce oil spills over the oil containment boom.

Draft: The minimum vertical depth of the surface layer below the waterline of the boom.

Height: Sum of freeboard and draft of containment boom.

Total height: maximum vertical height of oil containment boom.

Weight: The total weight of a fully assembled boom including the boom joint.

Total buoyancy: The weight of fresh water displaced by the sinking of the containment boom.

Total buoyancy ratio: The ratio of total buoyancy and total weight of the oil containment boom, referred to as buoyancy ratio. The high floating-weight ratio indicates that the oil containment boom has a strong ability to recover the floating state after being flooded. This self-recovery ability of the oil containment boom is called the wave property. The higher the floating-weight ratio, the stronger the self-recovery ability and the better the follow - up property.

Tensile strength: the breaking tension of the oil boom when it is broken.

Function

The functions of oil boom can be summarized as follows: containment and concentration, oil spill diversion and prevention of potential oil spill.

Oil spill containment and centralization After an oil spill accident occurs, the oil spill will spread and drift rapidly under the influence of tidal current, wind and other external factors, forming a large pollution area. When oil spills occur in open waters, coastal waters or ports, timely deployment of containment booms can timely control the oil spills in the diffusion.

 By dragging or reducing the containment range of the containment booms, the oil film can be gathered to a smaller range for recovery, which can not only prevent oil spills from spreading, but also increase the thickness of the oil film, which is convenient for recovery or other processing.

Oil spill diversion

After the oil spill accident occurs, the oil spill will drift and spread arbitrarily under the action of external factors. In order to facilitate recovery operations or to channel the oil spill flow to the designated place, especially in the river or coastal area with fast flowing water, in order to effectively control the flow direction of the oil spill to facilitate recovery or to prevent the oil from flowing into the sensitive area, the oil fence is usually used to set external prevention according to the set Angle.

Oil spill diversion generally has two conditions. One is the long-term deployment of oil containment boom, generally placed in the water intake and power plant; The other situation is to deploy the containment boom when the reef is near. Mainly, when the oil spill occurs, the containment boom will be temporarily deployed according to the specific situation to realize the oil spill diversion and lead the oil spill to the area that is easy to recover or to the area of other non-sensitive resources.

Prevent potential oil spills

Prevention of potential oil spills usually refers to the deployment of containment booms in advance to prevent and control oil spills in places where oil spills may occur or where there is a risk of oil spills according to the local waters.

 In this way, when there is real oil spill, it can prevent the spread of oil spill, take recovery measures, and recover the oil spill in the containment control in time. When a ship is handling oil in the dock or transferring oil in the anchorage, it is usually required to lay containment booms in advance to control the operation. Sometimes, the grounded or sunken ship before salvaging, also according to the actual situation should be appropriate containment control.

Storage and maintenance

The storage and maintenance of oil boom is directly related to the quick oil spill emergency response and effective implementation of containment operations. To ensure a quick response, the containment site should be located as close as possible to wharves, operational points and sensitive resource protection areas, and the containment site should be accessible to vehicles and ships. For outdoor oil containment booms, ensure that the storage area is well drained and insect pests are noted. Keep away from moisture and direct sunlight;

If stored indoors, it should also pay attention to moisture-proof and ensure good ventilation conditions. According to the situation, necessary measures should be taken in advance to prevent insect pests (such as releasing rodent poison, etc.);

The oil boom that needs to be folded and stored should be placed on the shelf and no other items should be stacked above it to avoid the deformation of the oil boom caused by excessive pressure, and regularly expand the stacked oil boom for inspection, and the original folding traces should be avoided when refolding; If it is necessary to store the oil boom on the reel, it should avoid distortion of the oil boom in the winding process, and regularly unwrap the wrapped oil boom and then recover it after inspection.

Maintenance of oil containment mainly refers to daily maintenance and maintenance after recovery operations. 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;

General inspection of the oil boom is not due to pull and other loading and unloading causes of oil boom wear, fracture, fiber aging, connector corrosion or damage, and necessary maintenance and replacement; For long-term deployment in the waters of the oil boom, also to be regularly maintained, generally according to the specific situation should be regularly hauled ashore, remove the oil boom attached to the surface of the Marine life and other adhesive;

No matter what kind of maintenance and maintenance is carried out, it is necessary to make detailed records and arrange inspection and maintenance items according to the records, to ensure that in a certain period of time, all the contents involved in the oil fence can be carried out a general inspection and maintenance, so that the oil fence is always in a good standby state.
