A system for providing a flexible cover in a storage tank is provided that reduces the amount of vapors released from a hydrocarbon liquid and other liquids and reduces the amount of product (liquid) lost to the atmosphere. The flexible cover is, in some embodiments, comprised of one or more membranes joined together along their respect perimeter edges. The membranes are made from a material or materials that allow the cover to roll up, or otherwise reduce the cross sectional diameter or area of the cover, to allow the membrane to pass through a port in a storage tank. Once inside the storage tank, the cover may return to its normal and/or predetermined dimensions to cover the upper surface of the hydrocarbon or other liquid, which reduces the release of vapors from the hydrocarbon liquid and other liquids.

A pneumatic motor propulsion source including a friction welding apparatus, a gas accumulator tank operably coupled to the friction welding apparatus, and an air compressor operably coupled to the gas accumulator tank.

A storage system for a petroleum product and related methods includes a floating roof seal having a vapor barrier and a coupling assembly. The coupling assembly includes a barrier securement and a shoe mount bracket for securing to a shoe plate. The barrier securement has a securement body and a resilient portion biased toward a clamp position and configured to selectively deflect relative to the securement body from the clamp position to an installation position. The barrier securement with the resilient portion in the installation position is configured to be received on the shoe mount bracket such that the barrier portion is positioned between the barrier securement and the shoe mount bracket. The barrier securement with the resilient portion in the clamp position is configured to compress the barrier portion against the shoe mount bracket thereby fluidly sealing the barrier portion between the shoe mount bracket and the barrier securement.

Floating roof tank for a volatile liquid have an outer roof and an internal floating roof with a primary seal with a support such that when the tank is empty, the floating roof will rest on the support whether the tank is in a vertical or horizontal position. The support enables the tank to be transported in a horizontal position without damage to the seal. The floating roof tank with support can be configured as a conical tank, flat bottom tank or slant bottom tank. The floating roof tank can also include a cleaning system and a flush mounted manway cover.

A defect perimeter sealing system that includes a plurality of perimeter base components that are arranged around a defect of a tank, where all of a top of the perimeter base components are encompassed or spanned by compression panels, the plurality of perimeter base components and the compression panels defining a fill zone between the plurality of perimeter base components and the compression panels, and an injected material in the fill zone.
