Seaflex - The Mooring System

SEAFLEX is an elastic mooring solution for docks/pontoons, wave attenuators and buoys that is unrivaled in its ability to keep the floating application stable and secure even in locations exposed to extreme weather conditions.

The main part of a SEAFLEX is a reinforced homogeneous rubber hawser; attached together with a high quality stainless steel plate.

Depending on each locations specific forces the product will be equipped with 2 to 10 individual hawsers per SEAFLEX unit.

According to tests monitored by Det Norske Veritas (DNV), one single SEAFLEX rubber hawser can withstand a force of drag greater than 10 kN, elongate over 100 % of its length and retract back to original length. While doing this the system is putting constant tension and providing stability to the moored application.


The SEAFLEX mooring unit is constantly being improved in order for us to be able to adapt the mooring system to your specific neeeds.

SEAFLEX mooring system is generally regarded to be more efficient and have a longer lifespan than most traditional mooring methods.

Over the years, we have added several features to the SEAFLEX units in order to improve the effectiveness and longevity of the system. We always strive for perfection.

The unique patented Bypass safety feature was added to the SEAFLEX unit as a standard component in 2008, and acts as a safeguard if the system should be exposed to conditions beyond the intended design. If the SEAFLEX mooring system is being used in highly corrosive areas, we can also offer our new Titanium Hybrid Model which ensures longevity even in the roughest environments.

Areas of use

SEAFLEX is suitable for both fresh and salt water, made only with high quality long lasting materials such as rubber, high-grade stainless steel and square-plait polyester rope.

We also offer a titanium hybrid model for severely corrosive areas.

The system can handle virtually any water level variation with references in locations with up to 35 meter (~115 feet) artificial variation, but is as beneficial in areas without water fluctuation providing added stability.

The system absorbs forces from wind and waves reducing the stress on the docks and boats during bad weather and improves stability. SEAFLEX moorings works as well in shallow water as it does in deep water, proven by references that has water depths up to 90 meters (~295 feet).


SEAFLEX can be dimensioned to handle everything from small residential docks and commercial marinas to large wave attenuators at locations that see hurricane strength forces.

After over 30 years of mooring docks/pontoons we are experts in knowing what is needed to securely attach virtually any floating application..

SEAFLEX are also frequently used for mooring navigational buoys and swing moorings. Other applications moored with SEAFLEX is among others, floating houses, floating solar panel parks and floating fountains. We are also involved in wave energy projects and other ground breaking aspects of ocean construction.
