QMF

QMF

Product catalog summary

Applications: The document outlines the use of QMF (Floating Wave Attenuator) for wave attenuation in coastal, sheltered, and estuarine areas to protect watersheds and docks. It is also applicable for bridge piers in adverse conditions.

Structure: The QMF is constructed from marine concrete with a density of 45N/mm², reinforced with galvanized steel mesh. The core is made of expanded polystyrene with a density of 15kg/m³. Fenders are made from impregnated Nordic pine.

Fasteners and Fittings: The system uses semi-flexible fasteners, including bolts, washers, and nuts made of galvanized steel, and blocks in marine elastomer.

Flexibility: The construction is modular with variable sizes, allowing for customization.

Mooring Systems: Options include chains, elastic moorings, piles, metal profiles, or radius arms.

Services: HDPE conduits are provided on both sides of the structure.

Live Load: The structure supports a live load greater than 5kN/m².

Accessories and Options: The document mentions the possibility of non-linear geometries (30º, 45º, and 60º), decks made of Nordic pine, exotic wood, or composite materials, and various cleats and bollards made of aluminum or cast iron. Additional features include marine elastomer fenders, concrete pigmentation, and extra connection and hatch boxes.

General Features: The QMF range consists of robust, resistant, and safe pontoons primarily used as wave attenuators for bay and port protection. The monolithic and modular units are built in sections of 15 or 20 meters, reducing the number of moorings and connections required, which enhances system performance and reduces maintenance costs. Widths range from 3 to 6 meters, with heights between 1.4 and 1.8 meters.
