A method of manufacturing a plurality of secondary containment panels and assembling and installing the panels in a secondary containment system of an above-ground liquid storage tank or other retention facility includes forming a plurality of flexible substrate pieces. A liquid impermeable coating is applied to the upper surface of each piece such that an edge segment of the piece remains uncoated. The coating is applied to the substrate piece in an indoor enclosure using a computer controlled robotic sprayer that applies a uniform coating. A system for coating secondary containment panels. An apparatus for spraying a coating on secondary containment panels. The apparatus may be computer controlled and operate automatically to coat the surface of the panel.

Methods of containing liquid introduced onto a support surface include forming the support surface with at least two mats, the mats forming a perimeter of the support surface. A plurality of berm members is positioned at least partially around or proximate to the perimeter of the support surface and extends upwardly relative to the mats sufficient to prevent liquid introduced onto the top of the support surface from leaking off of the support surface around the perimeter thereof.

The present disclosure relates to multi-layered elastomer-based liners. In at least one embodiment, a coated substrate includes a substrate and a first elastomer coating disposed on the substrate. The first elastomer coating is substantially free of sulfur and includes a first elastomer selected from the group consisting of a polyurea, a polyurethane, a polyurea-polyurethane copolymer, and combinations thereof. The coated substrate includes a second elastomer coating disposed on the first coating. The second elastomer coating includes a second elastomer selected from the group consisting of a polyurea, a polyurethane, a polyurea-polyurethane copolymer, and combinations thereof. The first elastomer is the same as or different than the second elastomer and at least one of the first elastomer or the second elastomer is a polyurea-polyurethane copolymer.

A hydraulic fluid assembly having an electric motor, a hydraulic pump, hydraulic fluid reservoir, and a hydraulic fluid spill over receptacle engaged to and underneath the hydraulic fluid assembly for capturing spill over hydraulic fluid and directing such spill over to a periphery of the hydraulic fluid spill over receptacle, where the periphery is accessible and away from the hydraulic fluid assembly such that the spill over may be manually wiped up with a cloth rag instead of causing a slippery pontoon boat surface.

A modular subsea fluid storage unit has a variable-volume inner tank having a rigid top panel and a peripheral wall that is flexible by virtue of concertina formations. The peripheral wall is extensible and retractable vertically while the horizontal width of the tank remains substantially unchanged. A side wall of a lower housing part surrounds and is spaced horizontally from the peripheral wall of the inner tank to define a floodable gap between the peripheral wall and the side wall that surrounds the tank. An upper housing part extends over and is vertically spaced from the top panel of the inner tank and overlaps the side wall to enclose the inner tank. The floodable gap and the upper housing part enhance thermal insulation and trap any fluids that may leak from the inner tank.
