SPECIFICATIONS
Tow Bridle
Enviro-USA™ tow bridles provide a strong, reliable connection for towing turbidity curtains, floating barriers, containment booms, and other marine equipment, helping distribute towing forces for safer, more controlled deployment and positioning in demanding marine construction, dredging, environmental containment, and waterway applications.
Tidal Compensator
Enviro-USA™ tidal compensators help maintain proper positioning and tension of turbidity curtains, floating barriers, and containment systems as water levels rise and fall, providing reliable performance for tidal waters, marine construction, dredging, sediment control, shoreline protection, and environmental containment applications.
Reefing Line
Enviro-USA™ reefing lines provide a durable, reliable solution for raising, lowering, and managing turbidity curtain skirts during deployment, retrieval, maintenance, and changing water conditions, helping improve handling and control in marine construction, dredging, sediment control, shoreline protection, and environmental containment applications.

Tow Bridle FAQs
A Tow Bridle, also called a Floating Tow Bridle or Towing Bridle, is a marine accessory used to connect to the end of a turbidity curtain, oil containment boom, or other floating barrier so it can be safely towed and positioned in the water. The bridle distributes the towing load across the barrier rather than concentrating the pulling force at a single attachment point, helping protect the boom or curtain during deployment.
Using a Tow Bridle helps distribute towing forces more evenly across the barrier, reducing concentrated stress on connectors and other structural components. This allows turbidity curtains and oil containment booms to be moved into position more uniformly and can help reduce unnecessary wear during installation, deployment, and repositioning.
Yes. In addition to towing and deploying floating barriers, Tow Bridles can be used to help secure turbidity curtains and oil containment booms to riverbanks, pond edges, beaches, or shorelines. Because the bridle spreads the load across the barrier connection, it can provide a more effective transition between the floating barrier and its shoreline attachment point.
Yes. Enviro-USA™ Floating Tow Bridles include flotation to help keep the bridle at the water surface if it is dropped during deployment or retrieval. This makes the accessory easier to locate and handle while crews are installing or repositioning turbidity curtains and oil containment booms.
Tidal Compensator FAQs
A Tidal Compensator is a marine barrier accessory designed to allow a floating turbidity curtain, oil containment boom, or similar barrier to move vertically as water levels rise and fall. It connects the floating barrier to a fixed vertical structure and allows the connection point to travel with changing water levels, helping the barrier maintain its intended position.
A Tidal Compensator typically connects the end of the floating barrier to a vertical structure or I-beam system. As tides or water elevations change, the compensator moves vertically along the structure, allowing the attached boom or barrier to rise and fall with the water instead of remaining fixed at one elevation.
A Tidal Compensator should be considered when a turbidity curtain, oil containment boom, or floating barrier is attached to a fixed structure in an area where water levels fluctuate. Common environments can include ports, harbors, docks, waterfront facilities, tidal waterways, and other locations affected by changing tides or water elevations.
Changing water levels can create undesirable loading or positioning problems when a floating barrier is rigidly attached to a fixed structure. A Tidal Compensator allows the attachment point to move with the water, helping the floating barrier continue to follow the water surface as tides rise or recede. This can improve the functionality of the overall barrier installation in fluctuating-water environments.
Yes. Enviro-USA™ identifies both a Standard Tidal Compensator and a heavier-duty HD Tidal Compensator. The appropriate system depends on the barrier, attachment structure, water-level variation, environmental conditions, and project requirements. A project specialist can help determine which configuration is appropriate for a specific installation.
Reefing Line FAQs
A Reefing Line is an integrated turbidity curtain accessory that allows crews to adjust the effective depth of the curtain skirt. Reefing lines are especially useful where water depth changes because of tides, changing bottom contours, or varying site conditions, allowing the curtain depth to be modified without replacing the entire barrier.
Turbidity curtains often operate in waterways where the distance between the water surface and bottom is not constant. Reefing Lines allow the curtain skirt depth to be adjusted for changing tides and bottom contours, making them useful for projects where water depth varies across the installation area or changes over time.
Yes. Reefing Lines can be used to raise or adjust the turbidity curtain skirt as site conditions change. By adjusting the deployed skirt depth, contractors can better accommodate tides, changing water levels, and variations in underwater contours while maintaining a more appropriate curtain configuration for the site.
Enviro-USA™ states that its turbidity curtain Reefing Lines are built into the curtain during manufacturing and are available upon request. Because the system is incorporated into the barrier, customers who expect changing depths, tidal conditions, or a need to periodically raise the skirt should discuss Reefing Lines with a project specialist when specifying the curtain.
