  • Secure the giants of the ocean

    Your crew and ship safety is the highest priority. Speed and efficiency are a daily challenge. Dyneema® SK78 is the strongest fiber for use in mooring ropes and tow ropes. For oil and gas tankers, containers, bulk cargo ships and naval vessels, ropes with Dyneema® ensure you have the most reliable and durable solution. 

    Secure the giants of the ocean
  • Durability

    Ropes need more than strength. They need to withstand extreme and regular abrasion through fairleads, winches, capstans or H-bits. Ropes with Dyneema® SK78 last longer than other synthetic ropes in demanding environments. By specifying ropes made with Dyneema® SK78, vessel operators can realize higher value in return for their investment. Durability delivers value. 

  • Rigorous on quality

    Ropes made with Dyneema® SK78 ensure consistent high performance from each and every fiber in the rope. Ropes made with Dyneema® are manufactured by leading specialists, only in close collaboration with DSM Dyneema. 
  • Designing with HMPE’s creep property? We can help.

    DSM Dyneema runs a multi-year program to determine the exact behaviour of ropes made with Dyneema® fibers under long term static loads. This has enabled us to develop a creep design tool by which we and our customers can predict creep rate and elongations, and estimate creep lifetime. Ropes with Dyneema® SK78 offer one of the highest creep lifetimes seen in commercial marine HMPE ropes.

  • The Dyneema® guarantee:

    Protection with Dyneema®, the world’s strongest fiber™:

    • Fast innovation in partnership with the industry
    • Over 25 years leadership innovating critical high performance products in Life Protection, Personal Protective Equipment, Medical, Maritime and Sports
    • Entire manufacturing process, from polymerization of UH Molecules to fiber spinning, owned by DSM Dyneema
    • Highest manufacturing standards with lowest tolerance
    • All production managed to DSM’s industry leading environmental standards
    The Dyneema® guarantee:
  • Super strong but lightweight

    Dyneema® has the highest strength to weight ratio among synthetic fibers. Weight for weight a rope made with Dyneema® is 7 times stronger than steel wire rope. 

  • Dyneema® shows higher tenacity

    Dyneema® has the highest tenacity when compared with other high performance fibers.

  • High tenacity and low elongation

    Dyneema® has very low elongation at break, and as a result, stores less energy. A rope made with Dyneema® has limited backlash or snaking behavior in the event of a line failure.

  • Creep estimation with Dyneema®

    Dyneema® SK78 exhibits much lower creep elongation than most other HMPE, and creep failure is seen much later as compared to other HMPE fibers, under the same temperature and load conditions. 

  • ShoreTension System with mooring lines with Dyneema®

    The device has already been successfully used at quays in various ports. The invention of the Rotterdam-based Royal Boatsmen’s Association Eendracht (KRVE) allows for vessels to be tightly and reliable moored alongside the quay in all weathers. This yields substantial advantages for both safety and operations.

  • Taking the drama out of a crisis

    When SMIT Salvage towed stricken cargo ship Modern Express to Bilbao, Spain, the story wasn’t over. The vessel was healing at 45 degrees, making it essential that once tied up, it couldn’t move. Enter ShoreTension with Dyneema® – the only system that can guarantee constant tension. This proved crucial for the safe and stable mooring and subsequent righting of the ship. The ShoreTension system eased the salvage work and significantly reduced the risks during the operation.

  • Faster mooring operations

    You don't need the world's strongest crew every time you moor. Mooring lines made with Dyneema® are light enough for one crew hand to manage. If you want to save time in every port, ropes made with Dyneema® make every mooring faster.
  • PT Indo Straits: No breakages in two years

    When PT Indo Straits was looking for new mooring lines for two of its transshipment barges, it knew what it wanted: something strong, safe, highly reliable and easy to handle that would perform well for at least a year in service in harsh working conditions. It wanted the best. Ropes made with HMPE fiber. But within a week of installing the ropes they discovered that not all HMPE fiber is the same. Feel Secure. Only with Dyneema®

  • Your safest choice

    Some ropes become dangerous when they break. Because ropes made with Dyneema® retract in a linear direction, there is limited backlash or snaking effect if they break. You can't make a lighter, safer choice for your crew.

  • Move to synthetic line cuts costs and increases safety

    When Shell needed to tow and position its newest and largest tension leg platform, the Olympus, during the U.S. hurricane season, it recognized the significant challenge on its hands. The combination of scale, complexity, and safety considerations led it to switch to Samson lines made with Dyneema® throughout the towing process.
