Aqualine FrøyaRing® cages can handle the enormous forces from mooring.

Thanks to the stays used between the two plastic tubes the Aqualine FrøyaRing® cages consists of, the structure cannot lose its shape even in the event of the collapse of one of the tubes.

The cage can withstand all the forces of nature in exposed locations.

The Aqualine FrøyaRing® cages is made of flexible plastic and strong steel in a solid combination. A combination that means maximum escape prevention.








  • Cages with steel fittings

    Flexible plastic and strong steel. The cage has proven its strength over 35 years of exposure to the effects of water, wind and weather.

    The Aqualine Frøyaringen® Cage with steel fittings:

    • double collar tube and handrail tube in PE 80/100 polyethylene plastic
    • fully-welded steel clamps attached with stays and chains around the full circumference
    • steel clamps prevent ovalising and pipe breaks
    • the nets are attached to the clamps and ensure that load is evenly distributed throughout the structure
    • linings between clamps and collar tubes reduce friction
    • the collar tubes can pitch and yaw freely between the clamps
    • the design is based on flexible plastic, strong steel, collar tubes and clamp/stay system working together
    • adaptable to local conditions
    • over 100 certified floating collars with circumferences from 70 to 300 metres
    Aqualine is one of the very few approved suppliers of floating collars, nets and mooring equipment.

    We only use certified plastic welders with extensive experience at home and abroad

    Our certificates are approved according to the requirements of NS9415.

  • Aqualine Bottom Ring

    A sinker tube provides extra safety, a better environment for the fish and makes net cleaning easier. All Aqualine FrøyaRing cages are certified for use with a sinker tube.

    Advantages of sinker tubes:

    Safety:
    • reduce point loading on nets
    • give full control during lining up
    • minimum risk of propeller damage to nets
    • stable net volume, even under extreme conditions

    Environment benefits:

    open mesh ensures good through-flow and less growth.

    'constant' cylindrical net volume means fewer injuries and stress
    a sinker tube makes delousing using sealed tarpaulins easier in large net cages

    Easier cleaning:
    - easy washing using brushes/high-pressure washes or divers
    - net drying without significant changes to net shape

    Aqualine has long experience of supplying and servicing sinker tubes. A sinker tube helps prevent the shape and thus the net volume from changing in locations subject to many storms.


    They are designed to make net handling easier.

    Bottom rings are raised gradually, using a winch mounted on a boat or the floating collar. Growth can then be removed while the fish remain almost undisturbed in the lower area.

    Delousing can also be performed safely and in a controlled manner, thanks to being able to maintain full control of the net volume.

    Bottom ring weight varies from 15–140 kg per metre. Local conditions govern sinker tube weight required
