Turbidity barrier installation differs substantially from one situation to another. In the case of a single section of Type 1 barrier that will be anchored on land and where the water movement is minimal, installation can be as simple as extending the barrier between anchor points, attaching it, and allowing the ballast chain to pull the curtain to the bottom. For anything more complex, the precise steps may differ but it will follow a general basic outline.
If you have multiple panels, it’s typically best to start by laying them out on an open shore area and connecting them before moving it into the water. In this step, it’s important to clear out the area before beginning because sharp rocks, barnacles, and abrasive surfaces like concrete can damage the curtain. Use heavy duty tarps to protect the curtain during this step if necessary. The types of panel connections vary according to supplier, so follow your supplier’s directions exactly to ensure a strong connection and effective seal between panels. Roll up the skirt section once you’re finished to prevent damage during deployment. Repeat this step, panel by panel, moving the completed sections out into the water as you go. Once fully assembled and placed in a staging pattern, you can tow the assembled curtain to the proper location. This requires care so that undue stress is not placed on any single connection or panel. If your supplier has provided towing connections, use them. Once in place, attach the curtain sections to their anchors. You should have an anchoring plan provided by your supplier, and some anchors may need to be deployed in advance. Follow your anchoring plan carefully and attach in the proper order to avoid dislodging anchors or damaging the curtain. Once the attachments are complete, the final step is to unfurl the curtain itself and allow it to sink. If necessary, this is the time to make adjustments to individual anchors.
