Technical Field

[0001] The utility model relates to the technical field of oil exploitation, and particularly relates to a rapid deployment device for an offshore oil boom. Background Art

[0002] An oil boom is an offshore oil spill emergency device that can effectively control oil spill accidents and recover the spilled oil at sea.

[0003] In offshore oil and gas fields, during the deployment process of a conventional oil boom deployment device, it is necessary to first hoist the container filled with the oil boom from the platform to the workboat, then pull out the oil boom in the container on the workboat, and then inflate the skirt of the oil boom. The vertical balance state of the skirt in water is achieved through the mechanical balance of the floats and counterweights. The hoisting and deployment on the workboat take a long time; during the inflation process, an external inflation method is also required to inflate the skirt, which not only requires a separate independent inflation device to be set up, but also requires a large amount of manual operation during the inflation process, which is time-consuming and laborious, seriously affecting the deployment speed of the oil boom and the timeliness of oil containment. Summary of the Utility Model

[0004] Aiming at the above problems, the purpose of the utility model is to provide a rapid deployment device for an offshore oil boom. Usually, the oil boom is stored in a sealed fiberglass shell to reduce the maintenance frequency. In case of emergency, it can be quickly thrown from the platform to the sea surface, and the skirt of the oil boom can be quickly inflated automatically, and there is no need to set up an external independent gas supply device, which not only improves the inflation speed, simplifies the oil boom deployment device, but also improves the deployment speed and efficiency.

On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be completely conveyed to those skilled in the art.

[0020] The present utility model provides a rapid deployment device for an offshore oil boom. By designing an automatic inflation generating device on the skirt of the oil boom, the self-inflation process of the skirt can be completed during the deployment of the oil boom, eliminating the step of external inflation. Through the throwing method, the deployment speed of the oil boom is improved. With this automatic inflation device and method, the external air pump inflation of the oil boom is replaced, simplifying the inflation process.

[0021] As Figure 1 shown, the rapid deployment device for an offshore oil boom provided by the present utility model includes: a roller 1 and an oil boom 2. During operation, the roller 1 drives the oil boom 2 to unfold and lay flat on the workboat and move to the sea surface. During recovery, the oil boom 2 moves from the sea surface to the workboat under the drive of the roller 1 and winds around the roller 1; a skirt 3 is provided on the oil boom 2; an inflation generating device 5 is provided at the bottom of the skirt 3 for inflating the skirt 3.

[0022] As Figure 2 shown, in the above embodiment, preferably, the inflation generating device 5 includes a fixed bag 51, an inflation generator 52, a connecting pipe 53, a fixing pin 54, and a skirt valve 55; the fixed bag 51 is provided at the bottom of the skirt 3, and there is a space for accommodating the inflation generator 52 between the fixed bag 51 and the skirt 3; the inflation generator 52 is provided in the space between the fixed bag 51 and the skirt 3; the skirt valve 55 is provided on the skirt 3; the inflation generator 52 is connected to the skirt valve 55 through the connecting pipe 53; the fixing pin 54 is provided on the connecting pipe 53 for controlling the opening and closing of inflation.

[0023] It should be noted that the inflation generator 52 needs to be pre-inflated with just enough air to fill the skirt.

[0024] In the above embodiment, preferably, the present utility model further includes a float 4 and a counterweight 6. The float 4 and the counterweight 6 are respectively provided on both sides in the width direction of the skirt 3; with the cooperation of the float 4 and the counterweight 6, the oil boom 2 stands upright on the sea surface.

[0025] In the above embodiment, preferably, the present utility model further includes a fixing bracket 7; a plurality of fixing brackets 7 are respectively provided below the oil boom 2 and are arranged at intervals along the length direction of the oil boom 2; the fixing bracket 7 is used to support the oil boom 2.

[0026] It should be noted that the bottom of the fixed bracket 7 can be fixed to the workboat.

[0027] As Figure 3 shown, the deployment process of the offshore oil boom rapid deployment device of the present utility model is as follows:

[0028] (1) Under normal circumstances, the oil boom is placed in the oil boom container 9 by means of "M-shaped" folding or roller winding. The oil boom container 9 is placed at the position of the inclined bearing platform 11 at the edge of the lower deck of the offshore platform 8 and fixed by the baffle 10;

[0029] (2) In the case of platform oil spill, by pulling out the baffle, the oil boom container 9 will be released and move under the action of gravity and fall into the sea. Under the impact, the oil boom container 9 will open, and the oil boom will be released from the container and start automatic inflation;

[0030] (3) The operators on the rescue ship will find one end of the oil boom, connect it, then start the ship, hold one end of the oil boom, and carry out the oil containment operation;

[0031] (4) When recovering the oil boom, the oil boom is automatically deflated, and then the oil boom is placed in the oil boom container by means of "M-shaped" folding or roller winding.

[0032] Among them, the automatic inflation process is as follows:

[0033] A. By setting an inflation generator on the oil boom, the inflation generator is fixed on the skirt of the oil boom, fixed by a fixing bag, and deployed as the oil boom is deployed;

[0034] B. During the deployment of the oil boom, the operator rotates the fixing pin of the inflation generator by a certain angle, and the high-pressure gas in the inflation generator enters the skirt of the oil boom for inflation;

[0035] C. After the pressure of the inflation generator and the skirt is balanced, the inflation is completed, the air fills the skirt space of the oil boom, and maintains a certain pressure and volume, ensuring that the oil boom is in an upright state under the action of the counterweight.

[0036] Among them, the automatic deflation process is as follows:

[0037] 1) During the recovery of the oil boom, the operator removes the inflation generator from the connecting pipe and takes it out of the fixing bag;

[0038] 2) The gas in the skirt of the oil boom will be released to ensure that when it enters the roller or folding, the internal pressure is atmospheric pressure, and it shows a flat pressure state after entering the roller or folding;

[0039] 3) Place the inflator back in place for recycling and use it again after inflation.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
