At the same time, the sea ice coverage period of about 3 months each year makes the disposal of oil spill accidents in the Bohai Sea waters more difficult and challenging
If the 2011 Bohai Penglai 19-3 Oilfield oil spill occurred during the winter sea ice season, it would cause more serious environmental pollution and economic losses

Embodiment Construction
[0029] 1. In the present invention, two single-piece airbags are compressed and sealed at the upper and lower edges to form a conjoined airbag, such as figure 1 shown. The single-piece airbag is made of 3mm thick rubber material with flame-retardant properties. Each airbag has sub-airbags①, the number is 8, and the sub-airbags are 3cm wide and 61cm high before inflating. The total height of the formed conjoined airbag is 80cm. , with a width of 46cm, a steel wire rope series channel with a diameter of 2cm is reserved at the upper part, and a channel with a diameter of 7cm is reserved at the lower part as a counterweight steel pipe and steel wire rope channel③;
[0030] 2. The hollow part between the two airbags is equipped with a steel round pipe ⑥ with an outer diameter of 6cm and a thickness of 1cm as a counterweight;
[0031] 3. After the configuration is completed, the one-piece airbag is connected in series at the upper end with a stainless steel wire rope with a diamete...

The invention relates to a method for containment and control of oil spills in crushed ice waters, comprising: making a conjoined airbag, the conjoined airbag consists of two single-piece airbags, both of which are made of flame-retardant materials, each The monolithic airbag comprises an upper edge, a lower edge and a plurality of mutually disconnected sub-airbags (1) arranged side by side between the upper edge and the lower edge, and the upper and lower edges of the two monolithic airbags are respectively sealed and connected Together, a rope channel (2) for passing the rope is provided along the upper edge; a counterweight (6) is arranged in the hollow part between the two single-piece airbags; the rope is passed through the rope channel (2) on the upper edge of the conjoined airbag ; Inflate each sub-airbag (1) to finally form an oil boom with a drop-shaped cross-section configuration; select one or more conjoined airbags according to the actual demand length, and connect them to form an integral oil boom screen; Oil spill containment. The invention can improve the containment and control efficiency of oil spill accidents in ice-covered waters.
Description
technical field [0001] The invention relates to an oil spill confinement control method that can be applied in crushed ice areas. Background technique [0002] In recent years, with the increasing development, storage and transportation of global offshore oil, the risk of major oil spill accidents at sea has increased accordingly. Moreover, after an oil spill accident, it will experience multiple different weathering processes at the same time, resulting in significant changes in its physical and chemical properties. These processes include: diffusion, evaporation (volatilization), emulsification, optical oxidation, decomposition, precipitation, refilming, tar ball formation, and biodegradation. Among them, in the first few minutes of the oil spill, under the action of wind and current, the oil spill film can form a diffusion range of hundreds of square meters. If timely and effective treatment measures are not taken, it will seriously threaten the marine ecological environ...
