Oil boom lease
The oil containment boom is a kind of equipment that the floating body with skirt under the water gathers the oil and dirt on the water surface to prevent their diffusion. Portable booms are commonly used to prevent the spread of oil pollution in oil spills at sea and in ports. It is composed of inflatable floating body, skirt, tension belt, counterweight chain, anchor parts, etc. it is fixed around the oily water surface that needs to be fenced with anchors. It can be divided into marine type, offshore type, port type and other types according to the use area, and has corresponding different technical data.
The functions of oil containment boom can be summarized as follows: containment and concentration, oil spill diversion and prevention of potential oil spill.
Oil spill containment and concentration
After an oil spill accident, the oil spill will rapidly spread and drift under the influence of tide, wind and other external factors, forming a large pollution area. In case of oil spill in open water, nearshore waters or ports, oil containment booms shall be set up in time to control the spilled oil in diffusion. The oil film can be gathered in a small range for recovery by dragging or narrowing the enclosure range through the oil containment booms, which can not only prevent the spread of oil spill, but also increase the thickness of oil film for recovery or other treatment.
Oil spill diversion
After an oil spill accident, under the influence of external factors, the spilled oil will drift and spread at will. In order to facilitate the recovery operation or to dredge the spilled oil flow to the designated place, especially in the area with turbulent river or near shore water flow, in order to effectively control the flow direction of the spilled oil for recovery or to prevent the spilled oil from entering the sensitive area, the oil containment boom is usually used to set an external defense according to the set angle. There are generally two conditions for oil spill diversion. One is to arrange the oil containment boom for a long time, which is generally arranged at the water intake and power plant; The other is to arrange oil containment booms near reefs, mainly to temporarily arrange oil containment booms according to specific conditions when oil spills occur, so as to realize the diversion of oil spills and lead the oil spills to areas that are easy to recover or other non sensitive resources.
Prevent potential oil spills
To prevent potential oil spills usually means to arrange oil containment booms in advance for oil spill prevention and control according to the local water conditions where oil spills may occur or there is an oil spill risk. In this way, when oil spills really occur, the oil spills can be prevented from spreading, and recovery measures can be taken to timely recover the oil spills in the containment. When a ship carries out oil loading and unloading operations at the wharf or oil transfer at the anchorage, it is usually necessary to arrange an oil containment boom in advance according to the specified requirements for setting control; Sometimes, a grounded or sunken ship should be properly enclosed and controlled according to the actual situation before it is salvaged.
