Dyneema® DM20 fiber: engineered for smarter systems
When the future of global energy lies in the balance, every fiber of every offshore operation counts. And some count more than others – like Dyneema® DM20 fiber. This Dyneema® grade is carefully designed to bring offshore energy projects, both traditional and renewable, to life as safely and efficiently as possible.
The result? Successful projects that power up wind power while driving down the cost of energy for all.

Pull-in ropes
Dyneema® enables STRENGTHplus+
Mooring lines and subsea tethers made with Dyneema® are uniquely strong – but there’s much more to it than that. Dyneema® DM20 fiber is the only HMPE fiber that’s suitable as a load-bearing core for permanent installation and has a DNV-approved lifetime performance model.

Cutting the costs of offshore energy
At Dyneema®, we’ve got decades of offshore experience behind us, woven into our fiber technologies. And we’re proud to support the industry with high-performance tethers, tendons, and mooring ropes made with Dyneema® DM20 fiber – as strong as steel but 85% lighter, for greater time and cost efficiency during transport and installation.
For more efficient offshore energy
Engineers can support you in design choices
Lightweight fibers offer design freedom and installation benefits
Long lifetime suitable for permanent moorings
Bespoke technologies for cut- and abrasion-resistant mooring line covers
Mooring lines that are reliable under pressure
Demand for offshore energy is rising. Projects are growing in size and complexity and heading into deeper waters. Safety and reliability are the ultimate priorities in tough offshore conditions – especially when deadlines are tight.
These challenges mean the limitations of mooring ropes and subsea tethers made from conventional steel or generic high-modulus polyethylene (HMPE) are increasingly under the microscope. The good news? Mooring lines and subsea tethers made from Dyneema® fibers are more than capable of taking the strain.
For greater peace of mind
Predictable longevity
Performance-driven retirement criteria
Support from our engineers
Anti-abrasion and anti-cut solutions
High strength-to-weight ratio
Near-neutral buoyancy
Superior service life
Excellent resistance to fatigue and creep
Reduced chance of failure
Making offshore energy projects more sustainable than ever
It’s pretty simple: in a world that’s woken up to the sustainability challenge, Dyneema® delivers the lowest carbon footprint per unit strength of all high-performance fibers. Opting for more sustainable mooring and tethering solutions made with Dyneema® fiber can fast add up to a lower footprint for your offshore operations.
How? Upstream, 100% of the energy used to make our fibers comes from renewable sources. Downstream, lightweight Dyneema®-based mooring lines and subsea tethers enable less energy use in transport and operations – plus, their longer service life means greater resource efficiency.
Dyneema® from bio-circular feedstock is also available for our customers in the offshore mooring industry. To make your offshore installation even more sustainable, choose Dyneema® fiber made from bio-circular raw material: the world’s first-ever bio-circular HMPE fiber.

Putting performance to the test
Products made with Dyneema® have been in use in offshore environments for three decades, with their lightweight strength making them a favored solution. But world’s strongest fiber™ offers so much more than just strength. Offshore applications are the perfect target for the all-round power of Dyneema® fiber, as proven by our suite of proprietary, state-of-the-art testing equipment.
In fact, we’re the only manufacturer to rigorously test both the fiber and the rope – simulating real-world conditions and evaluating product performance. And we use the results to help us engineer even better fibers and predict a rope’s lifetime based on various critical operating parameters.
Finding the right fiber grade
If you design or operate offshore energy systems or related infrastructure, you want to know your crews will be using the right tools for the job. Some lines need protective covers to provide extra resistance to abrasion or cutting. Contact us for our recommendations on the best Dyneema® grade for your application.
Dyneema® DM20 fiber
We recommend Dyneema® DM20 fiber for the load-bearing core of subsea tethers and mooring lines. Offering the highest fatigue lifetime of all UHMWPE fibers, it’s the only UHMWPE suitable for permanent installations.
Dyneema® SK78 fiber
If creep, abrasion, temperature, durability, and/or fatigue are critical issues in your application, this is the grade for you.
