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.

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.

HALO Dock is a floating structure with sections of HALO wave attenuator panels specifically designed to be mounted under the deck surface. This unique designs allows for an "invisible" use of our HALO technology to dissipate wave energy found in waves & boat wakes.
For such instances when a marina might want to protect their facility from wakes, but also wants to use the protecting area for a boat slip, the HALO Dock presents an ideal solution.

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.

The WaveWall is the answer to today's marina needs for wave attenuation. Atlantic-Meeco collaborated with some of the world's foremost marine engineering companies to create the Wavewall's breakthrough design. Extensive wave tank testing addressed multiple wave sizes, wave frequencies and anchorage.
Whether you are dealing with wakes from increased boat traffic or want to expand your marina into presently unprotected areas, the WaveWall offers exceptional performance and exceptional value.

The HALO Security Barriers are comprised of a series of energy absorbing panels which are configured to provide a physical barrier.
In the Maritime Security Barrier product, HALO panels are composed of environmentally friendly, maintenance free materials, which are deployed vertically, and linked by high quality marine grade cable together with additional panels into a floating bulwark.
The Security Barrier can include at least two rows of panels, connected by composite rods. In addition, depending upon client specification, the Barrier could include webbing below (to prevent underwater incursions) and razor wire above. Each system can be configured with integrated options such as sonar, lighting, sensors, audible deterrents and other security features. The entire Barrier will be moored using high-specification anchoring and mooring systems suitable for the environment where deployed.
The HALO Maritime Security Barrier works under the principles of strength and flexibility, using structural composition to stop any attempted threat.
If a boat strikes the face of the HALO Security Barrier at high speed, the barrier is designed to flex (absorbing energy) with the boat plowing into the barrier. HALO is not a "floating fence post" merely there to support a cable that provides stopping power, instead, a great deal of HALO's stopping power comes from the barrier itself.
In addition, by creating a progressive impact to stop a speeding vessel with an enveloping action, our energy-absorbing barrier can survive much higher velocities than a rigid barrier.

Prevent Beach Erosion with HALO Ocean
Conventional coastal protection systems just don't work. Breakwaters, groins, and jetties are static structures that cannot be tuned to varying wave conditions. Beach replenishment projects cost millions yet can't prevent escalating coastal erosion.
Let HALO Ocean protect your beach from destructive waves that strip sand and damage property. Only eco-friendly HALO with its modular panels can be customized and rapidly doployed to reduce waves by 80%, twice as much as other systems.
Protect Your Beach
HALO uses structural interference, buoyancy, and wave absorption to diminish wave force and restore a beach. HALO Ocean units filter out erosive waves and permit accretionary waves to pass through the system, accumulating sand. The HALO also acts as an artificial reef for wildlife.
HALO is composed of rows of non-toxic polyethylene panels. Rows are connected by adjustable, energy-absorbing Delrin rods, which allow the structure to recoil under extreme wave conditions and then reset itself. Wave energy passes through small openings in 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.

HALO Shockwave protects inland waterways and channels from the damaging force of waves and 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.
Eco-friendly protection for close quarters
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.
A HALO Shockwave unit installed on either side of an inlet or marina will reduce the current wave reflection caused by exposed smooth surfaces. HALO Shockwave is fully adjustable and installation is simple, rapid, and requires no special tools.
The combination of its unique design, along with energy-absorbing materials, allows the HALO Shockwave to provide calm waters for inlets, marinas, intra-coastal waterways and rivers.

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.
