Tethers, ropes and winch ropes for subsea applications

Meeting the challenges of deepsea operations

Subsea and deepsea installations present unique engineering challenges where precision and reliability are non-negotiable. Whether you’re deploying equipment at extreme depths or managing complex underwater structures, the right equipment can make the difference between project success and costly delays.

Efficient installation at depth

Efficient installation at depths is critical to staying on schedule and within budget. That’s where ropes and slings made with HMPE/Dyneema® technology deliver measurable advantages.

When you choose Dynamica tethers, ropes or winch ropes engineered with HMPE/Dyneema® , you benefit from exceptional strength-to-weight ratios, minimal elongation under load, and significantly reduced recoil risks. These properties translate directly into safer operations and more efficient installation procedures in demanding subsea environments.

Expert engineering support throughout your project

Drawing on over two decades of specialised experience in subsea applications, our engineering team works closely with you throughout the project lifecycle. From initial concept development through design optimization to final deployment, we provide technical expertise that helps you select and implement the optimal solution for your specific operating conditions.

Dynamica Tethers - mooring of MWA

5 huge MWA structures. 90t. 12.5m x 14 m. Manufactured by NOV. Installed by Havfram at Balder field. The installation required each of the MWA’s to be pulled down to enable connection to the preinstalled suction mid-water arch foundation – consisting of 140t anchors using Dynamica MWA Tethers.

Flexibility & maneuverability on request

A world-class provider of cable pull-in, termination and testing services for the entire offshore industry contacted Dynamica Ropes for advice.

Edvard Grieg tie-back

Technip was looking for high performance fibre slings with as little elongation as possible, low weight and an extremely low length tolerance (0.20 % or less) to be used for the tie-back operation at 100 m depth in the oilfield in the North Sea. Dynamica SafeLift Slings met this challenge in fact the slings were made with 0.15 % length tolerance.

Pull-in improvement for Chestnut Oil Field

Offshore operations are challenging and any risk have to be eliminated. National Oilwell Varco asked us to develop a pulling system for Chestnut FPSO - an oilfield located approx. 290 km east of Aberdeen, at a water depth of 120 m.
