Dynamic stiffness in mooring designs, referring to the stretch of the mooring line under load, has long been an overlooked and underappreciated parameter in the Floating Offshore Wind Turbine (FOWT) industry.
Gradually, the industry is recognizing its critical importance.
Early demonstrators have highlighted serious issues caused by excessive dynamic stiffness under load, such as shock-loads.

At FibreMax, we remain at the forefront of innovation and custom solutions.
We are proud to announce that we have been working diligently with our Fiber-Partners Dyneema, Teijin Aramid, and our technology partner Mocean Offshore to develop a software solution that allows users to validate the dynamic stiffness behavior based on their defined mooring line values.
Upon completion of this validation, the specific mooring line configuration can be exported to a .DLL file, enabling users to import this configuration into OrcaFlex for simulations that closely mirror real-world conditions.

Crucial data collection has been performed, in close cooperation with our fiber partners, through extensive testing on scaled FibreMax tendons.

These tests were conducted at different frequencies and loads to cover various wave periods and load scenarios, including hurricane/cyclone forces (ULS).

This data is exclusively applicable for FibreMax Parallel Wound Tendons and not for any other constructions (e.g., ropes).

The fibers incorporated in this unique software tool are:
Dyneema DM20 (HMPE)
Polyester
Teijin Twaron LM 1000 (Aramid)
Teijin Twaron HM 2200 (Aramid)
Teijin Twaron UHM 3200 (Aramid)

We have just released Beta Version 2.4.2 to a select group of FOWT partners for final testing. We anticipate the official release in early Q4-2024.
