Abstract:
An attachment to a drainage hose for use on a stockpiling barge that includes: a fluid pervious bag formed of a flexible fabric material, the fluid pervious bag having an open end and a closed end, a ballast material attached to or retained within the closed end of the fluid pervious bag, and means for securing the open end of the fluid pervious bag about a hose. Also disclosed are the attachment in combination with a drainage hose and a stockpiling barge, a method of filtering runoff water from a stockpiling barge through the use of the attachments, and a method of preventing non-dissolved organic or inorganic contaminants from flowing from a stockpiling barge into a body of water through the use of the attachments.
Abstract:
Modular boom curtain section are disclosed, including zipper elements for connection of adjacent modular boom curtain sections. Boom curtains assembled from the boom curtain sections, boom systems containing those boom curtains, and methods of assembling the boom systems are also disclosed.
Abstract:
A containment/exclusion boom (10) includes a boom curtain containing an upper curtain portion (12) and a lower curtain portion (14) that are connected together at a central region (22), the upper and lower curtain portions each being formed of a sheet of flexible fabric material that allows the flow of water therethrough; and first and second support systems (24 and 26, respectively) which can be positioned in a body of water and connected separately to distinct positions on the boom curtain; whereby the first and second support systems maintain at least one of, but preferably both, the upper and lower curtain portions in a substantially sloped arrangement upon introduction of the boom into the body of water.

Abstract:
An attachment (10) to a drainage hose (40) for use on a stockpiling barge that includes: a fluid pervious bag (12) formed of a flexible fabric material, the fluid pervious bag having an open end and a closed end, a ballast material (30) attached to or retained within the closed end of the fluid pervious bag, and means (28) for securing the open end of the fluid pervious bag.
Abstract:
A water filtering intake system includes a plurality of inlets (24) in communication with a water intake pump and a containment/exclusion boom having a support system (14) positioned in a body of water and a curtain of flexible fabric (16) which allows movement of water therethrough. The curtain has an upper end connected to the support system and a means for maintaining the lower end against the floor of the body of water. The curtain surrounds the inlets and filters water drawn through the curtain when the pump is operated and water is drawn through the inlets.
Abstract:
Disclosed are a sound attenuation sleeve for use on a piling during underwater construction and a method of using such a sleeve for attenuating underwater transmission of sound and/or shock waves during underwater pile driving operations.

Abstract:
A submersible boom that includes: a support system containing a substantially horizontal support member; a boom curtain formed of a flexible fabric material, the boom curtain being suspended from the substantially horizontal member; and means for raising and lowering the substantially horizontal support member between first (with the substantially horizontal support member at least partially above the surface of a body of water) and second (submerged) positions. Use of the boom in accordance with a method of allowing boat traffic ingress into and egress from a region within a body of water is also disclosed.
