Description
Technical field
The present invention relates to a kind of spill containment method that can be applied in trash ice area.
Background technology
In recent years, with global offshore oil development, accumulating it is growing, the risk of great marine oil overflow accident occurs
Increase therewith.Moreover, after oil spill accident occurs, multiple different weathering processes will be undergone simultaneously, in turn result in its physics, chemistry
The significant changes of property.These processes include：Diffusion, evaporation (volatilization), emulsification, photo oxidation, decomposition, precipitation, again film forming,
Tar ball forming and biodegradation.Wherein, occur in oil spilling in the first few minutes time, in the presence of wind and stream, oil spilling
Film can form the range of scatter of hundred square meters, if do not take timely and effectively treatment measures will serious threat marine ecology
Environment and human lives.Therefore means effectively are contained, it is necessary to take in time, oil spill area is controlled in accessible scope
It is interior, then recycled.Especially when there is ice covering on sea, the chemical and physical properties of one side oil spilling will have pole
Big change, the floating ice on the other hand to drift about can hinder to contain the advance of equipment, now the difficulty of containing of oil spilling greatly increased.
At present, the oil fence used both at home and abroad is typically made up of three parts：Floating body (float), screen body (middle skirt
Body), counterweight (weight of bottom).Three respective functions in part are respectively：Floating body provides buoyancy for the oil fence, it is ensured that it can
Swim on the water surface；Skirt body is connected to below float, and it forms one of barrier under water, and effect is so that the oil fence is gathered around under water
There is the drinking water of certain vertical depth, it is ensured that certain thickness oil spilling can be surrounded；Mass is connected under skirt body, effect is that balance is enclosed
Oil barrier, and also provide tension force for skirt body and can form barrier.And set currently for the spill containment of open water research and development
It is standby to have frozen water domain, can be due to influenceing to fail caused by Sea Ice Drift.
The above-mentioned oil fence is applicable only to open water, will be in Sea Ice Drift when it is applied to sea ice Water Area Covered by VTS VTS
Effect is lower to occur following several failure behaviours：
In the presence of the sea ice that drifts about, the oil fence is it is possible that sink, so as to reduce the height on the oil fence water surface
Degree, the oil spilling for causing to be contained cover the oil fence under certain energy effect and splashed；
In the case of the mixing of oily ice, oil spilling appears in the latent posture of subglacial, so as to cause oil fence skirt body depth
Deep with long-pending oil depth etc., the oil spilling contained is fled from below skirt body, and then triggers oil spilling leakage；
In the presence of the sea ice that drifts about, the oil fence can not stably stop or vertically on the water surface, in turn result in oil spilling
Diffusion；
Because ice is a kind of crystalline material of water, there is higher intensity and toughness, oil fence work under certain condition
When making and ice interaction, may result in the oil fence and scratched by ice, make the oil fence damaged and lose afloat stability, contain effect
Rate reduces.
For these reasons, in the processing of many real engineering practices, find situation be present even in micro broken ice
Under, traditional oil fence is also possible to fail to containing for oil spilling.Therefore, for may have ice Water Area Covered by VTS VTS occur oil spilling thing
Part is, it is necessary to research and develop energy oil-control while have both the oil fence of control ice ability.
At present, it is existing in China's Bohai Sea water area has come into operation production platform and the sea-bottom oil-gas pipeline laid
More than 70% was on active service more than 15 years, and this just promotes the risk of the great marine oil overflow accident of Bohai Sea water area generation to increasingly sharpen.Meanwhile
The sea ice covering phase of annual 3 months or so causes the oil spill accident disposal of Bohai Sea water area to face bigger difficulty and challenge.If
The oil spill accident in the Peng Lai of the Bohai Sea in 2011 19-3 oil fields occurs that between there is the ice age on sea in the winter time, then more serious environment will be caused
Pollution and economic loss.Therefore, research and development are for there is frozen water domain to contain the oil fence product of efficiency high to there is ice Water Area Covered by VTS VTS oil spilling
The emergency disposal measure of accident seems particularly significant.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of the existing oil fence, is combined with the environmental quality of ice Water Area Covered by VTS VTS, research and development one
Kind is applied to the oil fence for having ice Water Area Covered by VTS VTS oil spill accident, using such a oil fence, provides a kind of trash ice spilled oil in water area and contains
