Abstract: A system for containing spillage from a tanker at a moorage. The system in its deflated stated state remains submerged so as not to obstruct the passage of a vessel thereover. Once a vessel is moored in place thereover, the perimeter boom is inflated to bring the boom to the surface to surround the entire ship. A liner continguously attached to the boom extends downwardly to form impermeable walls and a floor below the tanker. The system is routinely deployed prior to any on-loading or off-loading operation when spills are most likely to occur. Deflation of the boom upon completion of the operation causes the entire system to once again assume its submerged state.

Abstract: A system carried aboard tankers which upon deployment serves to positively contain oil leaking therefrom. A boot sealingly engages the hull while a buoyant boom supports the periphery of an impermeable liner attached to the boot. A skirt extending from the boom is tethered to the deck of the vessel. The entire system is normally maintained in a compact, folded form spooled up on a storage reel which is positioned on the deck of the tanker.
