Floating Breakwaters 4016, 4020

Product catalog summary

Overview: The document describes the QMF system, a floating breakwater solution designed for marinas, yacht harbours, and leisure ports. It is composed of steel-reinforced concrete pontoons with a polystyrene core, functioning as a wave attenuator with a robust structure.

Specifications: The standard units are available in 16 or 20-meter modules, reducing the number of necessary moorings and joints, which in turn lowers maintenance costs. The width of these units ranges from 2.4 to 5 meters. The concrete used has a strength of 45N/mm², is watertight, and reinforced with galvanized steel mesh. The core is made of expanded polystyrene with a density of 15kg/m³.

Applications: The QMF system is suitable for wave attenuation and protection of basins and docks in estuaries and semi-sheltered coastal environments. It is also used for berthing and mooring large vessels and landings in exposed areas.

General Characteristics: The system features impregnated Nordic pine fenders, silent and semi-flexible joints with galvanized steel bolts and elastomer blocks, and a modular construction with variable dimensions. Fixings and moorings primarily use chains or flexible moorings, with optional piles, metallic sections, or radius arms. The live load capacity is above 4kN/m².

Optional Accessories: Nonlinear geometry of the floating breakwater is possible at angles of 30º, 45º, and 60º. Deck options include Nordic pine wood, exotic pine, or composite materials. Additional accessories include cast iron and aluminum cleats and bollards, marine elastomer fenders, and pigmented concrete.

Technical Specifications: The document provides detailed specifications for models 4016 and 4020, including dimensions, weight, net capacity, and joint strength. Both models have a length of 16 or 20 meters, a concrete width of 4 meters, a height of 1.8 meters, a draft of 1.20 meters, and a freeboard of 0.60 meters. The weight is 34 tons for the 4016 model and 42 tons for the 4020 model, with a net capacity of 6.0 kN/m² and joint strength of 2x812 kN.

Advantages: The QMF system is highlighted for its stability, resistance, strength, and safety.

Marinas, Yacht Harbours and Leisure Ports FLOATING BREAKWATER IN REINFORCED CONCRETE The QMF system is composed of steel reinforced concrete pontoons with polystyrene core. This equipment works as a wave attenuator, having a massive and extremely strong structure. GENERAL CHARACTERISTICS 45N/mm2 concrete, watertight, reinforced with galvanized Strength steel mesh. Massive and extremely resistant units Core Expanded polystyrene, density 15kg/m3 Its geometric configuration, construction method and type of joints makes it a very good choice for protection of basins and in-port docks. Fenders Impregnated nordic pine Joints Silent and semi-flexible, with galvanized steel bolts and elastomer blocks Flexibility Modular construction with variable dimensions The standard units are usually built on 16 or 20m modules; these lengths decrease the number of necessary moorings and joints, and has advantages in terms of the overall behaviour of the system, reducing maintenance costs. The width ranges between 2,4 and 5m. Fixings and Primordially chains or flexible moorings; optionally piles, moorings metallic sections or radius arms Services Cable ducts in PEAD pipe Live load Live load capacity above 4kN/m2 Optional accessories Nonlinear geometry of the floating breakwater are possible (30°, 45° e 60°).
