- the world´s leading cage supplier AKVA group is the world’s leading supplier of both plastic and steel cages. Polarcirkel, the most recognized brand in aquaculture, invented the plastic cage concept in Norway in 1974, and has since supplied more than 42,000 cages worldwide. The renowned Wavemaster steel cages originated in Ireland in 1985, and more than 12,000 cages have since been delivered globally. In order to ensure the highest possible quality, competitive pricing and on-time deliveries, the cages and components are manufactured in many different regions. All cages are installed by professional installation teams, and serviced by professional AKVA group service technicians. AKVA group invests heavily in innovative and professional R&D in order to remain the leading supplier of cages; not only to improve products in the short term, but also to look into the future of tomorrow’s demands for cage technology.

Polarcirkel Cages

Strong and rigid HDPE hand rails.

New PIM Bracket design provides superior strength.

A secondary redundancy safety chain placed inside the outer floating pipe is optional.

Experience is a crucial success factor in the fish farming business. AKVA group (Polarcirkel) invented the plastic cage in 1974, and has since supplied more than 42.000 Polarcirkel Cages and 12.000 Polarcirkel Boats. The cages are made from raw materials especially suited for the dynamic loads of the sea, and are available in a wide range of models, shapes and sizes to suit individual needs.

Many have tried to copy these products, but none have managed to match the genuine Polarcirkel designs and quality builds. Plastic cages started out as small single pipe circles, but now our largest models approach 200m circumference, and with floating pipes of 500mm diameter. Both circular and square cage systems are available. Combined with AKVA group´s global sales and service network, thePolarcirkel Cage is well proven and recognized worldwide.

Safe Polarcirkel walkways

In order to increase crew safety on fish farms, another Polarcirkel innovation was launched in 1999; the integrated Polarcirkel Walkways. The anti-skid walkway panels fit securely between the two floating pipes, forming a stable and safe working surface. The PE pressure moulded panels are held in place with strong and flexible continuous PE tubing inter-locking the panels to the PIM brackets.

The Polarcirkel cages include smart solutions for fully integrated walkways, sinker tube systems, safety floatation and system redundancies.

Polarcirkel quality and certificationAll Polarcirkel Cages are manufactured and assembled in accordance with AKVA group’s Quality Assurance System (ISO 9001) which is certified by DNV (Det Norske Veritas). All cages in Norway are designed in accordance with NS9415 (Norwegian Standard 9415 for cage farming equipment to prevent fish escape).

Polarcirkel Cage History

32 33

Proven Sinker Tube concept

As cages grew bigger and nets became harder and harder to control in strong currents, Polarcirkel invented the sinker tube concept in 1989. A concept that later has been adopted as an industry standard. The Polarcirkel Sinker Tube consists of a 200-280mm heavy walled PE pipe filled with steel wires (typically 20-70 kg/m). It is supported by strong ropes fastened through the stainless steel sleeve in the PIM brackets.

Polarcirkel cage sizesThe most popular models are the circular cages in 315, 400, 450 and 500mm floating pipes with circumferences from 90-160m.

Polarcirkel Cages - designed for rough conditions... Strong Polarcirkel PIM Brackets

Extensive use of PE (Polyethylene) in our PIM (Pressure Injection Moulded) brackets eliminates corrosion, minimizes expensive and difficult maintenance, and substantially increases cage lifespan compared to steel brackets. This is especially important in areas with high salinity, warm water temperatures and choppy seas.

Only strong and high quality PE is used for Polarcirkel brackets, while many suppliers use weak and low quality rotationally moulded Medium and Low Density Polyethylene. This makes the Polarcirkel brackets superior in terms of structural strength, durability and UV resistance. This is especially important in high energy offshore farm sites and areas with high UV radiation from the sun.

For areas prone to icing, such as Norway and Canada, another critical advantage of the Polarcirkel HDPE brackets is that they will not ice up as steel brackets do. Icing is a dangerous safety problem for all floating structures, including cages. Heavy ice overloads the cage, reduces stability and jeopardizes overall cage integrity. As the name indicates, the Polarcirkel cages are well suited for extreme arctic conditions!

All Polarcirkel Cage designs are carried out by our professional R&D department. Independent marine engineering consultants are also involved in advanced static and dynamic load calculations to ensure all designs meet or exceed expected real life loads as well as applicable industry standards.

AKVA groups proven sinker tube system uses a vertical rope. No metal parts, such as chain and shackles, can there-fore cause damage to the net.

All the weight of the net and sinker tube system is supported by the floating pipe - NOT by the handrail.

When harvesting, the net volume is reduced by lifting vertical ropes of the sinker tube system. This leaves no load on the handrails.

Forget corrosion! Photo showing a Polarcirkel bracket after ten years in saltwater!

A wide range of flexible Polarcirkel cages are designed for extreme weather conditions, such as here on Norway’s stormy coastline at 70° North.

Polarcirkel cages are known for their strong railings and high reserve buoyancy, which is crucial in case of sudden excessive net loads or icing.

Wavemaster is the world’s leading supplier of steel cages with close to 10.000 cages delivered since 1985! The cages provide an ideal platform for fish farming. Wide non-slip walkways with high free-board around all sides of the cages allow the operator full flexibility of operation and easy access from cage to cage. This is becoming essential for good husbandry and maintenance. The compactness and simplified mooring arrange-ments make Wavemaster Steel Cages a very attractive option for many sites.

The cages are available in a wide range of models, single- or double string systems and sizes up to 40x40m to suit individual needs.

The patented moulded rubber hinge system allows the cage structure to adapt to the wave profile, thereby reducing loads on the member and ensuring longer life of the cages.

The Wavemaster Steel Cages include smart solutions for fully integrated non-slip walkways, net supports and floats with self-draining top.

Wavemaster has a proven track record of installations on a wide range of sites and in many different climates around the world, such as here in Chile.

The handrail system provides tie off points at the main walkway level, posts to support the net and removable hand-rails. They can easily be removed while the net is tied to the posts.

The upper surface of each float incorporates sloping surfaces so that any feed or debris deposited can be washed away by wave action or water hose. High reserve buoyancy is crucial in case of sudden excessive net loads.

Wavemaster - a trusted steel cage concept...Wavemaster began producing steel cages in Ireland in 1985, in Canada in 1988 and in Chile in 1990, and today supplies cages to all world markets. The large number of cages currently in use on a wide variety of sites, operating under diverse wave and wind conditions world wide, has demon-strated the reliability of the Wavemaster design. Produced locally and designed to suit local markets, Wavemaster provides the most cost effective steel cages available to the industry. Steel cages are suitable for sites with moderate exposure and strong tidal currents. Combined with a global sales and service network, the Wavemaster Steel Cages are a well proven concept indeed!

Steel cages allow for a simplified mooring arrangement due to it’s system structure and design.

The wide walkways provide superior support for predator nets, well spaced from the fish net. This is a crucial feature for some areas.

A wide range of strong, high quality mooring systems are also available in various dimensions.

Feed Barge

Safe and stable cage construction built to withstand icing and rough conditions.

Feed barges can be moored at the end of steel cages and provide easy access to the cages for farm staff.

Wavemaster steel cages are also available with driveable centre walkway, such as here in British Columbia, Canada.

Hot dip galvanizingAll components are hot dipped galvanized after manufacture. This has proven to be the most effective and durable coating for use on fish pen structures.

Ongoing R&DAll of the Wavemaster designs are continuously updated to reflect operating experience and the changing work practises of the fish farmers using the equipment. This continues to make Wavemaster the leading edge steel cage in the fish farming industry.

Secure floatsTwo different types of floats are available. The standard type provides normal free board while the high type provides extra high free board. All are rotationally moulded, UV stabilized polyethylene filled with expanded polystyrene and then sealed. They are attached to the cagestructure using galvanized steel bands and bolts (Chile & Scotland) or bolts with fender washers (Canada).

Environmental data helps you to stimulate growth

Environmentally friendly, flexible and smart solutions...In Net Cleaning, filtered high pressure sea water is used to remove marine fouling on the nets. Idema Net Cleaners use rotating cleaning discs mounted on support frames in various shapes and combinations. We use rugged, tailor-made high-pressure pumps to drive the cleaning discs. The cleaning process starts with submerging the frame on the inside of the net, using only sea water under high pressure. Idema cleaning systems do not use chemicals or scrubbing action making them environmentally friendly while ensuring minimal wear on the nets.

This Optical Oxygen Sensor connects directly to the feed system and can stop the feeding at low oxygen levels.

Idema Net Cleaners also keep nets clean in tropical waters, as here in Thailand.

It is extremly important to keep the weight of the cages light in cold periods. Icing and fouling can indirectly cause breakdowns and serious damage.

The width of the cleaning path ranges from 80cm, up to 290cm for the largest model using 7 washing discs. The discs are generally delivered in 40cm diameterbut can also be ordered in 30cm or 50cm diameter.

Heavy Duty Cleaning discs with smooth front rail in stainless steel ensures minimal wear of the net. The discs have low resistance in the water, extra high rotation speed - from 750 to 1500 rpm depending of water pressure, flow rate and cleaning disc diameter.

The Heavy Duty center bearing with silicium-carbide pressure housing mean less service calls and minimal down time.

Extra strong 2-layer steel reinforced high pressure hose with strong connector fittings for heavy duty use.

A video camera provides full control of the Net Cleaning

On the larger Idema frames we offer tailor-made camera and video systems that provide a full overview, and the possibility to inspect of the nets. A camera installed direcly on the Net Cleaner will send you crystal clear video images that can be saved for later inspection and documentation of the net cleaning process.

One of the new models in the Idema range; an effective 7 disc washing rig with a stainless steel protective for the net.

A wide range of models - up to 7 cleaning discs The large Net Cleaners can be operated in automatic mode by two persons using a crane, winch, cap stand or as a integrated option on ROV (Remotely Operated Vehicle). The smallest Net Cleaners can easily be operated from the cage by a single person.

The environmental conditions in the cages are the most vital parameters for top quality and faster biomass growth.

With a Polarcirkel Cabin workboat you can easily visit the site and watch the net cleaning on a PC screen.

With one of our smart camera systemsyou can watch the net cleaning bothabove and below water, via cable or via a wireless sensor network (CAP).

Why use a camera to monitor feeding?Cage sizes have rapidly increased over the last 20 years, and as a result, the visible area has decreased accordingly. In a cage of 160 diameters, only 0,2% is visible from the surface. Therefore a submersible camera is a requirement for monitoring and controlling feeding.

Environmental data is a critical feeding parameter...

To know the environmental data as temperature, oxygen and current speed are factors that are important inputs when feeding fish. In the Akvasmart CCS Feed System all these factors can be set to automatically control or adjust the feeding. All environmental data will be logged and can be used in further analyses either in AkvaControl or in Fishtalk.

Temperature - the foundation for all feeding regimes and growth models. The Akvasmart Temperature Sensor is a reliable and robust sensor that can be submerged at desired depths. Accurate real time readings are displayed and logged by the AkvaControl Feed System software. AkvaControl can cal-culate the expected daily feed amount based on feed tables with measured temperature data. The Akvasmart Temperature Sensor is connected to the Akvasmart CCS Feed System either by connection to the Akvasmart CCS Selector Valve or via the CAP network.

Oxygen – an important factor for growth and fish welfare.The Akvasmart Oxygen Sensor is connected to the Akvasmart CCS Feed System and can stop the feeding at low oxygen levels in water. The Oxygen Sensor is an optical sensor that is robust and dependable with no need for water flow. The only maintenance is periodic cleaning and there is no need for re-calibration. The principle of operation is to illuminate the oxygen as the reflected light is a measurement of dissolved oxygen in the water.

Environmental current – knowledge’s prevents feed wasteThe Akvasmart Current Sensor is connected to the Akvasmart CCS Feed System and will prevent feed waste caused by tidal current that pushing pellets out of the cage. The Akvasmart Current Sensor is located in strategic positions at site and you set which cages that are connected to the sensor and the maximum tidal current speed (in cm/sec) that allows feeding. When the current speed exceeds the limit, the feeding temporarily stops in these cages and resumes at slack current later, all other cages will be feed as scheduled.

The integration between Akva Control and Fishtalk software provides the choice of where and when to analyse the environmental data.

Continuous data readings from the cages are transmitted through the Akvasmart wireless sensor network (CAP) or via an EAP (Environmental Access Point).

Using the Temperature Sensor in combi- nation with an Oxygen Sensor gives a good picture of the environment.

The Current Sensor angles like a pendulum when exposed to currents. The angle is measured and converted electronically to cm/sec.

The machined bronze housing prevents marine fouling and makes the sensor low maintenance.

The absolute oxygen concentration is measured by illuminating a membrane with modulated blue light and by reading the phase changes in the reflected red light. The signal is then linearised and temperature compensated.
