Floating Breakwater

The Floating Breakwater is a floating wave attenuator that utilizes recycles materials and vegetation to create a sustainable green infrastructure product. Layers of matrix sheets are adhered together using Coast Guard approved polyurethane marine foam. The foam also provides buoyancy, enabling the breakwater to float. A nylon mesh netting with rings woven in encapsulates the Floating Breakwater, creating six anchor points. The entire breakwater is ultraviolent (UV) protected and reinforced with spray polyurea. Vegetation is planted into pre-drilled holes where it grows hydroponically, creating a hybrid breakwater structure with durability and aesthetic wetland appeal.

Research & Field Tested

Research conducted by the University of South Alabama suggested that the Floating Breakwater is most effective at attenuating short period waves, such as wind chop. Research also demonstrated that the ideal deployment depth is approximately 3.5 feet to 4.5 feet.

Floating Breakwaters have survived category 1 hurricane conditions of 90 MPH winds and 3-4 foot storm surge in South Louisiana.

Engineered Anchoring Design

Anchoring is critical to keeping the Floating Breakwaters in Place, especially in higher wave energy environments. It is recommended that Floating Breakwaters are anchored in place using 3 flight round rod helical anchors. These anchors have proven to hold Floating Breakwaters in place.

Floating Breakwaters are designed as a floating system that accommodates for fluctuating water levels and eliminates the risk of system settlement. This makes them ideal for locations where soil quality is poor.

Anchoring System

The engineered anchoring design of the Floating Breakwater utilizes equally distributed netting anchor points connected to helical anchors which are uniquely suited for the conditions of coastal marshes.
