Barges, concrete sea walls, and the like are static structures that cannot adjust to changing conditions. They cost thousands each year to maintain, yet waves still damage property.
Let HALO Harbor protect your marina. For less than half the cost of conventional technologies, the proven HALO absorbs rather than deflects the force of vessel wakes to reduce waves by 80%, twice as much as other systems.
Since HALO filters water flow instead of obstructing it, it can be tuned to block out only harmful waves allowing the natural flushing of harbors.
HALO is composed of rows of non-toxic polyethylene panels. Rows are connected by energy-absorbing Delrin rods, which allow the structure to recoil under extreme wave conditions and then rest. Wave energy passes through small openings on the panels to the area between the unit and its mooring points. In this area, waves overlap to create interference, which dissipates the wave's energy.
It's time to finally stop the waves.

BREAKWATERS
Martini Marinas’ floating breakwaters are designed to comply with the findings of detailed hydraulic experiments. The result is a wave-breaking structure shaped like a catamaran, which makes it extremely effective in countering the motion of the waves and dissipating the energy generated by their impact. To guarantee even greater stability, Martini Marinas developed an original system of differentiated volumes for its breakwaters.
Unlike conventional breakwaters made of reinforced concrete anchored to the seabed, the Martini Marinas series does not run the risk of being put out of action by excessively deep
waters or by silting. Each model comes in a choice of two versions, for marinas located on the sea and on the lakes, and can be completed with dunnage and connecting gangways.

SF Marina System Ab has been designing and manufacturing floating concrete breakwaters since 1984 after many years of manufacturing large concrete pontoons. We have installed them in a wide variety of sites in quite adverse conditions with no failure to date. The units installed are performing the functions we have designed for with great success. Our breakwaters are specifically designed for and are required to be moored with chains, sinkers and anchors.
Our Marina installation in Acapulco which is protected by one of our floating breakwaters was exposed to the hurricane Pauline some years ago without any damage. And the hurricane Floyd passed through our Marina installation at Charleston last september without any damage.
The geometry of this pontoons, in combination with our patented coupling and an advanced mooring system, makes our floating breakwater an excellent wave attenuator. This pontoons have been developed gradually over a number of years and today there are numerous reference-installations in use both in Sweden and abroad. The breakwaters from SF MARINA are all-concrete pontoons with all the advantages of high stability and buoyancy. The all concrete and styrofoam construction of the pontoon produces a very high degree of buoyancy thus making it virtually unsinkable. As a result of the use of high quality materials, coupled with a thorough manufacturing process, the pontoon enjoys a long life-span. Each standard pontoon is designed to accept electrical and water supply services. Normally, the pontoons would be moored using chains and blocks. This pontoons are first and foremost as a floating breakwater.

Floating pier BW400 (BW300), is a wave attenuator and high-stability mooring quay able to protect partially sheltered docks. This pier consists of a system of modular elements interconnected by semi-elastic joints. The modules are floating structures made of reinforced concrete conglomerates. Inside, a core of polystyrene foam make them light and unsinkable. Concrete is obtained from a mixture of pozzolanic or blast furnace cements and is therefore suitable to the marine environment. Selected aggregates assure a high-quality concrete.

We study and we manufacture concrete floating breakwaters and floating pontoons of big dimensions and inactivity.
The above dimensions and weights have been resulted from studies on particular regions and conditions. The policy of our company is to make distances of floating breakwater after of study on the particular harbour and not the sale of the concrete breakwaters.

wakes. This energy-absorbing wave attenuator acts as a barrier and prevents the structural wear and tear on docks and seawalls, while greatly reducing erosion of channel banks.
The eco-friendly, tunable HALO™ Shockwave has articulating arms that can be secured in either a horizontal or vertical orientation directly upon a solid surface, seawall, bulkhead or on pilings.
The structure allows wave energy to pass through small openings on its face to the area between the unit and its mooring points. In this area, waves overlap to create interference, which dissipates the wave's destructive energy. Securing the unit in place, articulating arms contain dampening pads for the absorption of severe energy loads.

HALO ECO units are the smallest of the HALO line, are portable, rapidly deployed, and easily adjusted to changing climates once in the water.
HALO ECO units require non-invasive anchoring methods, and offer the same low maintenance and self-cleaning properties of other HALO models.
HALO ECO is an ideal solution for wetlands restoration, riverbank protection, pollution control, aquaculture, and oil containment.
HALO ECO works with nature to dissipate waves and wakes, foster growth of aquatic vegetation, allow littoral drift of sand, permit the natural flushing of an environment, protect sensitive wetlands, and act as an artificial reef for wild life.
Like other HALO wave attenuators, the HALO ECO is designed to allow a portion of wave energy to pass through small openings on its face to the area located between the unit and its mounting points. This area is where the waves overlap and interfere with each other causing dissipation.

Concrete has long been recognized throughout the world as the preferred material for marina docks and wave attenuators. It provides mass for stability, rigidity for strength and durability, and is a long term solution in fresh and salt water marine settings. Where a floating wave attentuator is called for, concrete offers a usable economic option.

Floating breakwaters can only be used economically in fairly sheltered locations where effective fetch is less than 6 km (i.e. wave period generally of less than 4 seconds).
The breakwaters reduce the wave height and strength by directly deflecting some of the energy and dissipating smaller amounts by friction and turbulence. Significant amounts of energy are dissipated by the movement of the floating breakwater due to its size and flexible anchoring.
The main technical parameters i.e. width, height, weight and moment of inertia, are selected for maximum attenuation capacity. The connection between the pontoon units is semi-flexible with sufficient rigidity to enable the breakwater to work as a continuous structure - a significant advantage in wave attenuation capability.

Commercial floating structures to meet the needs of berthing larger vessels and provide wave attenuation for inshore locations.
Walcon Marine Ltd is proud to represent in the UK, SF Marina from Gothenburg, Sweden who specialise in the production of top quality all concrete floating breakwater structures.
Considerable wave research has been carried out over the last 20 years. on the use of floating structures as wavebreaks in sheltered locations such as estuaries and lagoons. The wake of passing vessels and short period waves can still create unpleasant conditions in yacht harbours. Recent experience has shown that floating pontoon breakwaters are effective in attenuating waves in marginal sites.
