Buoyant barrier and method for installing the same
Abstract
Abstract A BUOYANT BARRIER IS PROVIDED, AS WELL AS A METHOD FOR INSTALLING THE SAME, WHICH MAKES IT POSSIBLE TO ESTABLISH THE BARRIER TO CONFINE AN OIL SPILL AT A REMOTE LOCATION IN A RELATIVELY SHORT TIME AFTER THE SPILL HAS OCCURRED. THE BARRIER STRUCTURE CAN BE OF FLEXIBLE SHEET MATERIAL AND IS PROVIDED IN LIGHT WEIGHT PACKAGED FORM, READY FOR DELIVERY BY AIR, THE STRUCTURE BEING SUCH THAT VERY HIGH RATES OF DEPLOYMENT ONTO THE SURFACE OF A BODY OF WATER ARE PRACTICAL. IN ITS PACKAGED FORM, THE BARRIER STRUCTURE IS COMPLETELY FREE OF WEIGHTS. IN DEPLOYED FORM, THE WEIGHT OF THE STRUCTURE IS SUPPORTED BY AIR-INFLATED BUOYANCY CHAMBERS, AND THE STRUCTURE IS STABILIZED BY A CHAMBER OR CHAMBERS FILLED WITH WATER FROM THE BODY OF WATER ON WHICH THE STRUCTURE IS DEPLOYED.
