Anchoring a Containment Boom
Q: Hi. I am interested in your boom anchors and containment boom. I plan on weaving this boom through two docks and attaching it to the pier. I will have two anchor points on shore where the water meets the land. How can I anchor this boom to the shoreline? How can I secure the boom to the pier with all the tides?
A: Thank you for contacting us! When using any one of our Containment Booms or turbidity barriers, we offer several different boom anchors to help secure your boom in place during use. Depending on your project requirements, different anchors and rope lengths can be used.
Types of Boom Anchors
Several Marine Grade Anchors are available to help secure you boom or silt barrier into place on a specific body of water.
Available anchors include:
- 24 lbs. Danforth Galvanized Steel Anchoring System
- 40 lbs. Danforth Galvanized Steel Anchoring System
- 8 ft. x 3/8" Galvanized Steel Chain Lower Rods
- 60 ft. x 5/8" Polypropylene Rope Upper Rode with Thimbles
- 12" Diameter Polyethylene Hard Sheel Jim Buoy
- 6 ft. x 5/8" Polypropylene Painer Rope with Thimble and Galvanized Shackles
Securing the Boom to Shore
In order to secure you boom to an anchor on the shoreline, any rope, cable or chain that goes from the end of the boom to the shore anchor point can work. The goal is to try and keep your anchor point no more than 3 feet from the high water elevation.
Securing the Boom to Pier
To secure the boom to a pier, the best approach would be to use a tidal compensator. This will allow the boom to raise or lower with changing water levels or tides, without placing strain on the curtain. There are standard (pictured to the right) and HD models available, depending on water and weather conditions.
A second choice would be using a short poly rope. Using other items, such as a steel hoop or ring, can be problematic as the waves tend to cause the loop to get stuck on the piling. This will, in turn, cause damage to your boom.
Using a poly rope can be an excellent way to accommodate for changing water levels as it allows for more flexibility than a metal hoop.
- Look to the bottom of your boom or silt barrier. Here you should find a ballast chain the runs the length of the barrier. On this chain should be larger loops. See if one of these loops is matched with a piling.
- If a loop is matched with a piling, tie your rope through this ring and around your piling.
- If there is no loop matched with a piling, use a punch or other similar object and cut a small hole into the vinyl surrounding your ballast chain. Thread your rope through this hole into a link on the chain, and then back out through the other side of the curtain. Tie off your rope with this.
- Trial and error may be necessary to find the right placement in your flow or wind.
Using poly may require replacement approximately every year, but it does allow for more flexibility and helps keep your boom in place.
