Using Dynamica Winch ropes saves time
A specialist in winch solutions for offshore cable pulling
At Danish Krigers Flak (DKF), they used traditional steel wires for array cable pulling of array cable strings for 72 turbines, but they were on the lookout for a replacement that was safer and more effective.
DKF is situated in the Baltic Sea in the easternmost part of Danish territorial waters. The array cable pulling was a time-consuming operation as it had to be done using two installation ships in order to connect the 72 turbines with their respective offshore substation.
Until recently the only available winch rope for cable pulling was a traditional steel wire. The running had to be attached to a hammer lock at the end, which in turn connected to 5 km of 800 mm array cable that was pulled along the seabed.
Not exactly a perfect working condition for a synthetic rope!
"Steel wire rope cannot give the flexibility required and it has always rubbed against the TP aperture causing paint damage to the infrastructure and causing the steel wire rope to splinter and require to be replaced”
The challenge: finding a winch system built for harsh environments
Winch systems operating in offshore marine environments must meet exceptionally high demands. The combination of saltwater exposure, abrasive seabed conditions, and the physical loads involved in cable pulling puts both equipment and personnel under considerable strain. In these environments, durability and reliability are not optional - they are essential. The risk of failure is not merely a financial concern; it is a safety issue. Any snag or breakdown with two large vessels waiting at sea carries significant operational and economic consequences.
As a master rope manufacturer with deep knowledge of rope made with Dyneema® or HMPE, Dynamica Ropes was asked to develop a bespoke installation solution that could go the extra mile where steel wire consistently fell short. The ability to install and, where necessary, repair winch lines quickly and efficiently on site was a key requirement - particularly given the scale of the DKF project and the controlled sequencing required to connect all 72 turbines without delays.
The solution: high quality winches
The solution was Dynamica Winch ropes with double shield coating (DSC) as they are custom-made and can be manufactured in continuous endless lengths - they are the ultimate synthetic replacement of the heavy and dangerous steel wires.
Dynamica's vast range of winch ropes means that bespoke products can be engineered for specific applications - from standard offshore lifting operations to the type of demanding array cable pulling seen at DKF.
Dynamica's solutions are compatible with most winch equipment commonly used across the industry, making them a practical choice whether the project calls for a full bespoke installation or integration with existing infrastructure on site.
“Using Dynamica rope saved time due to being faultless during all installations, having 2 large vessels in the sea waiting can be very costly if there are snags with the rigging [...] The ropes performed very well, there were no issues during any of the array cable pulling operations, each rope was attached to a winch with 5 turns around the drum. Dynamica performed fantastic with no fraying and withstand all conditions during operations the construction material if the rope allowed the flexibility and maneuverability during the installation to the TP."

Performance, reliability, and comfort features by design
Dynamica Winch ropes are designed with a hard fibre core, which makes them compact and dimensionally stable. The highly abrasion resistant braided polyester or Dyneema® cover ensures efficient protection against abrasion. These design choices are not incidental - they reflect a tested approach to rope construction that is applied across Dynamica's own range of rope products. Whether the application involves lifting, or specialist winch systems for marine use, the same principles of durability and reliability run through the entire supply.
When in operation, winch lines are subject to tension and in some cases the dirt, mud, rust can penetrate the rope. The abrasive elements can start to wear down the fibres and lower the performance of the winch ropes. The DSC protects the winch ropes against these abrasive elements. For operations in demanding environments - particularly offshore and marine settings - this level of protection is what separates a reliable winch service from one that carries unnecessary risk.
