Problems solved by technology

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

[0024] 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;

[0025] 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;

[0026] 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...

Abstract

The invention relates to an ice-resistant oil boom applied to an ice breaking region. The ice-resistant oil boom comprises a one-piece air sac, wherein the one-piece air sac comprises two single-piece air sacs made of a material with a flame retardant characteristic; each single-piece air sac comprises an upper edge, a lower edge and a plurality of sub air sacs (1) which are arranged between the upper edge and the lower edge in side by side and are not communicated with each other; the upper edges and the lower edges of the two single-piece air sacs are respectively sealed and connected together; a first balance weight (6) is arranged between the two single-piece air sacs; and a rope channel (2) for allowing a rope to pass is arranged along each upper edge. After each sub air sac (1) is inflated, the whole one-piece air sac forms a structure with a section shaped like a water drop. By using the ice-resistant oil boom, the containing efficiency of an oil spill accident in an ice covering water area can be increased.

Description

technical field [0001] The invention relates to an anti-ice oil containment boom which can be applied in the crushed ice area. 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 environmen...
