Abstract
Abstract A boom includes a plurality of boom sections joined end to end. Each boom section includes two or more parallel inflatable chambers which are joined with a weighted curtain which is reinforced for strength. Boom sections are stored compactly on respective reels. A substantial number of reels are arranged compactly in the hold of a carrier vessel which is smaller in size and has greater speed and maneuverability than vessels carrying known oil spill containment systems. Boom sections are consecutively unwound from their respective reels and connected end-to-end as they are deployed to form a continuous boom. The boom sections unwind naturally from the reels as the carrier vessel moves through the water away from a tender vessel holding the first end of the boom. The boom's deployment is controlled by a brake on an idler roller and a hydraulic crane's drive wheel on the reel, thus limiting manual handling to lighter-weight tasks. the carrier vessel, or, preferably, the tender vessel may inflate the chambers of the boom sections as they are deployed. The system is self-contained, as the carrier vessel is adapted to carry the tender vessel on its aft deck, releasing it when arriving at the spill site. Also, the tender can simultaneously deploy two substantially parallel booms, allowing an oil spill to be controllably segmented into smaller oil spills which are anchored or towed to calmer waters to await skimmer vessels.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
184 words
A method of deploying a boom for containing a spill of oil or other substance on the surface of water, comprising the steps of: partially unrolling a portion of a first boom section from a first reel aboard a carrier vessel; attaching a first end of the boom section to a tender vessel; causing relative motion of the tender vessel and the carrier vessel to further unroll the first boom section; partially inflating one or more inflatable chambers within the first boom section through one or more corresponding valve assemblies disposed near the first end of the boom section as the boom section is deployed through relative motion of the carrier vessel and the tender vessel; substantially stopping relative motion of the tender vessel and the carrier vessel as the unwinding of the second end of the first boom section approaches; partially unwinding a second boom section from a second reel aboard the carrier; attaching the second end of the first boom section to a first end of the second boom section; and completing the inflation of inflatable chambers of the first boom section.

The method of claim 1, further comprising: repeating the above process using additional boom sections and reels.
Claim 4
Dependent Claim
70 words
The method of claim 2, further comprising the steps, associated with the step of attaching boom sections, of: affixing a floatable spacer between the first boom section and the second boom section; and affixing a sealing device over and between the first and second boom sections and the floatable spacer so as to prevent flow of the oil or other substance from one side of the boom to the other.
Claim 5
Independent Claim
277 words
A method of deploying a boom for containing a spill of oil or other substance on the surface of water, comprising the steps of: partially unrolling a portion of a first boom section from a first reel aboard a carrier vessel; attaching a first end of the boom section to a tender vessel; causing relative motion of the tender vessel and the carrier vessel to further unroll the first boom section; partially inflating one or more inflatable chambers within the first boom section through one or more corresponding valve assemblies disposed near the first end of the boom section as the boom section is deployed through relative motion of the carrier vessel and the tender vessel; substantially stopping relative motion of the tender vessel and the carrier vessel as the second end of the first boom section approaches being unwound from the reel; inserting one or more valve assemblies into the one or more respective inflatable chambers near the second end of the first boom section; partially unwinding a second boom section from a second reel aboard the carrier; attaching the second end of the first boom section to a first end of the second boom section; connecting one or more connecting tubes between the one or more respective valve assemblies at the second end of the first boom section to one or more respective valve assemblies at the first end of the second boom section, allowing flow of gas from the inflatable chambers of the first and second boom sections; simultaneously completing the inflation of inflatable chambers of plural boom assemblies using the one or more connecting tubes; and removing the one or more connecting tubes.
