How did gulf oil spill happen？

 Offshore oil drilling is inherently risky, so the more RIGS there are, the more accidents there are. And now, in order to get more oil, humans are frequently drilling into the deep sea. Oil tanker accidents often occur in the course of oil transportation. For example, on March 16, 1978, the Liberian tanker Amolgo Cadiz struck a reef in Brest Bay, Brittany Peninsula, northwestern France, carrying 220,000 tons of light crude oil into the sea. On 19 July 1979, a Liberian-registered tanker, the Atlantic Express, collided with another Liberian tanker, the Aegis Captean, off Trinidad and Tobago, spilling 300,000 tons of oil from both tankers into the sea. After the ship sinks, the fuel oil in the tank can continue to leak out for a long time. According to statistics, the world every year due to shipwrecks into the sea of oil up to 500,000 tons. Hopetopway oil boom is a necessary equipment to prevent oil spill pollution in water area. To prevent oil spill pollution, the first step is to prevent the spread of oil spill. In addition to intercepting the oil spill, the boom can also guide the oil spill and make it as concentrated as possible for further recovery and treatment.

Here is the contene list:

●Characteristics of oil booms.

●Classification of oil booms.

●Containment boom recovery and storage.

△ Booms are necessary for oil spill control. When oil spill occurs, containment booms should be used to contain oil spill and prevent its diffusion. Booms can also direct oil spills to suitable areas to make them as concentrated as possible, providing conditions for physical recovery of oil spills.

Characteristics of oil booms.

(1) High strength, oil resistance, wear resistance, weather resistance, long service life.

(2) Good waverider, good stability, strong oil stagnation ability.

(3) Small storage volume, good mobility, easy to lay, recovery and storage.

(4) Multiple independent gas chamber structure, when 1 or 2 adjacent gas chambers leak, the section of oil boom can still float on the water surface.

(5) Suitable for use in wharves, harbours and offshore oil platforms of rivers, rivers, lakes and seas. Especially suitable for oil spill emergency treatment.

Classification of oil booms.

◆ According to the wrapping material can be divided into: rubber containment, PVC containment,PU containment, net containment and metal or other materials made of metal or other containment.

◆ According to the floating body structure, it can be divided into: solid float containment boom, inflatable containment boom, floating and sinking containment boom, etc.

◆ According to the use of water environment can be divided into: calm water containment boom, calm rapids water containment boom, non open water containment boom and open water containment boom.

◆ According to the use of the situation can be divided into: permanent layout containment boom, mobile layout containment boom and emergency containment boom.

◆ According to the use can be divided into: general purpose containment boom, special purpose containment boom, such as: fire containment boom, oil suction containment boom, weir containment boom, beach type containment boom and other special purpose containment boom.

Containment boom recovery and storage.

1. The recovery process of boom is opposite to that of expansion, but it should be combined with storage mode.

2. Oil boom storage can be placed on shore boats. However, it is easy to damage the oil fence when entering the water and then recovering it, so it is best to have rollers and slideways beside the boat on the shore. Booms can be discharged, stacked (be careful not to disturb) or winched on shore.

3. The solid float containment boom is relatively large in volume when stored by capstan, but it can be mechanically retracted and lowered more conveniently. The boom can be hoisted section by section onto the ship on shore by means of cranes and other devices.

4. Detach all anchor lines from booms prior to recovery. Storage place should be ventilated, avoid direct sunlight.
