Dyneema® mooring ropes manufactured by Dynamica Ropes are light and have the same or greater breaking strength as steel wire with the same diameter (depending on the construction) DYNAMICA mooring ropes and marine rope solutions are made with Dyneema®; the strongest man-made fiber in the world.
Mooring lines made with Dyneema®
DYNAMICA mooring ropes made with Dyneema® have a better abrasion resistance and very high UV stability. Dyneema® is much more resistant to UV than any other synthetic ropes. The above properties make DYNAMICA ropes made with Dyneema® easier and safer to handle for the crew and operators.
Furthermore, it is recommended by OCIMF that a pennant or grommet, made of nylon or polyester is fitted to all Dyneema® mooring ropes in order to absorb the shock loads due to high seas, winds and tides ranges.
Key benefits using Mooring ropes made with Dyneema®
- Low weight and easy handling.
- Floats in water.
- Less crew required.
- Less heavy equipment and men for handling.
- Similar strength as steel wire rope of the same size and often stronger.
- Resistant to most chemicals.
- No rust, long lifetime in the maritime environment.
- No need for grease/lubrication.
- High tension and bending fatigue resistance.
- Low elongation. The backlash energy stored is much lower than in the steel wire rope.
- Safer worksites.
Rope pendants made with Dyneema® fibers
The ultra-light and very strong DYNAMICA pendants are developed for the maritime market in order to offer a safer, hand friendly and low-risk alternative to steel wire strops, chains or traditional synthetic ropes for heavy duty towing ropes. Both of these “yesterdays” materials are heavy, inflexible, difficult to rig and dangerous if they break. They require many deckhands and additional equipment for handling and rigging.
In case of the steel wire there is a risk of recoil and sweep when steel wire breaks under too high load. The twisted construction of wire will recoil with extreme energy and sweep the area next to it with dangerous untwisting strands.
DYNAMICA towing pendants are used as tugboat ropes worldwide and ropes made with Dyneema® successfully replace the steel wires and other synthetic fiber. DYNAMICA ropes are also used for pendants in applications where shock loads or high seas do not occur.
Towing rope solutions for Harbor and Deep Sea Towing
Lightweight and flexible tow ropes made of high-performance DYNAMICA ropes ensures that users don’t have unplanned stops and delays. DYNAMICA ropes are significantly easier to use than other fiber ropes or steel wires, because of these characteristics.
DYNAMICA’s high-performance synthetic ropes made with Dyneema® are size-for-size as strong as wire ropes, and often stronger.
DYNAMICA marine tow rope has similar elongation as steel wires but it floats since the weight of Dyneema® fibers is 7 to 10 times lighter than steel wire – at the same strength.
DYNAMICA ropes for harbor towing are UV resistant have a better abrasion resistance than any other synthetic ropes.
Key benefits using Towing ropes made with Dyneema®
- Due to the low elongation of Dyneema® (SK78), in combination with the 12 strand braided construction of DYNAMICA ropes prevents the recoil reaction which is very much reduced if the rope should separate.
- Low weight makes the rope easy to handle, reducing crew required on deck.
- Being generally of 12 Strand construction and due to the reduced elongation of the Dyneema® (SK78) rope, the result of force being applied at one end results in at least a 98% efficiency of that force being supplied as a resulting force at the working end of the rope.
- Not affected by seawater conditions.
- No rust or grease on the deck or fairleads.
- Clean deck area with no grease or dirt.
- Fewer strain injuries from excessive weight.
- Can be easily spliced on board.
- Clean and hand friendly. No “meat hooks” and no “bird nests”.
Protect your mooring ropes, main towing line and pendants with a DYNAMICA protective cover
To provide additional protection to the DYNAMICA Tow ropes and Mooring Lines we recommend the use of Dyneema® (SK78) or polyester Chafe Protection Sleeves. These products are non-load bearing and provide additional protection to the working ropes over high-risk areas where sections of the ropes that come in contact with the uncontrolled areas of serviced vessels such as Bollards and Fairleads/Panama Chocks.
We always recommend that this extra chafe protection is fitted in the eyes of ropes, and strongly suggest it also be fitted on the working end of all tow ropes the protect the area of Tow ropes that are in contact with serviced ships fittings or port facilities that Tug crews have no control over. Where requested, the whole working end of a towline can be covered.
DYNAMICA SUPREME PRO jacket and eye cover is a polyester braided cover that protects the rope against abrasion. It also has the ability to make the line sink, which is an advantage in some solutions.
DYNAMICA SUPERIOR PRO jacket and eye cover is a Dyneema® (SK78) braided cover and provide even more protection of the main rope, because of the Dyneema® braid.
DYNAMICA ORBIT cover jacket and eye cover allow the crewmembers to inspect the main rope for conditions that are unwanted.
Dynamica Ropes often delivers rope and marine solutions where only the exact parts of the rope that are exposed to heavy abrasion, are machine overbraided with a protective cover.
Covers can be applied as follows:
- In the soft eyes
- In the soft eyes and over the splice
- In the soft eyes, over the splice and the agreed distance towards the middle of the rope
- On the entire length of the mooring or towing rope.
These options would be provided with consultation with the customer and Tug crew.
