The shipping industry is rapidly growing worldwide, yet many challenges are expected to arise: High investment in infrastructure while at the same time reducing operational costs and ensuring the safety of employees. These are not only the major challenges for the shipping industry but also factors that determine the characteristics that the marine industry expects from the ropes they use.


Ropes made with Dyneema ®, the world’s strongest fiber™, are well-established on the market and appreciated by ship and harbor operators. Mooring ropes made with Dyneema® have a proven track record by providing safe mooring for all kind of ships worldwide. Dyneema® offers a solution that is superior over steel wire and other synthetic ropes in terms of economic efficiency and workplace safety and shows that superior strength and durability do not necessarily lead to compromises in weight and handling.

Customers value ropes made with Dyneema® as they are:

  • Stronger
  • Lighter
  • Easier to handle
  • Safer
  • Require less maintenance
  • More durable

The world’s lightest heavy-duty rope

Traditionally ropes, made of steel, are well-known for their strength but are heavy, difficult to handle, and pose a significant threat to employee safety. Conventional synthetic ropes overcome some of these drawbacks but still are too bulky and heavy. Ropes made with Dyneema®, on the other hand, combine all the requirements that the shipping industry nowadays has for its ropes. Its maximum strength and minimal weight make Dyneema® the world’s strongest fiber – and the ideal rope for the shipping industry.

Mooring lines made with Dyneema®

  • are as strong as steel-wire rope of the same diameter, yet less than one-seventh the weight
  • are about 60% of the diameter and 30% of the weight of an equally strong polyester or nylon rope
  • have an elongation of less than 2.5% at break, which is close to steel wire and much less than polyester or nylon ropes
  • outperform steel wire and synthetic ropes in terms of tension, bending fatigue and abrasion resistance
  • float on water, have a good UV resistance, are resistant to most chemicals and salt, and do not absorb water

Thus, a mooring rope made with Dyneema® is not only made of the strongest fiber in the world but is also the world’s lightest rope – the perfect solution for the shipping industry.


The mooring line industry is not yet fully aware of the potential of aramid-based mooring line solutions. This while Teijin Aramid has more than two decades of experience in developing innovative aramid materials that strengthen and improve products for use in the maritime industry. In particular, mooring lines (for both static and semi-static applications) that integrate Teijin Aramid’s materials Twaron® and Technora® offer improved performance standards and longer lifetimes.

Key benefits when using aramid:

  • Low weight
  • High strength
  • High thermal stability
  • Improved durability
  • Reduced risk of injury
  • Reduced maintenance

A smart investment that saves money and ensures safety

Mooring ropes made with our High Performance Fibers are a great opportunity for the shipping industry to address two of their major challenges: Reducing operating costs and ensuring a safe work environment. Dyneema® ropes for instance are lightweight ropes, which makes them easy to handle, reduces mooring times and ultimately optimizes utilization and efficiency of vessels. Mooring ropes made with Dyneema ® have a longer lifetime compared to traditional ropes which reduce the total cost of ownership and operating costs for ship and harbor operators.

The fact that ropes made with Dyneema® are a synthetic material reduces the maintenance to a minimum: Dyneema® ropes do not require greasing but still do not damage any part of the ship. Further, the absence of grease reduces the potential impact on our environment. When talking about efficiency one also has to consider the individual in touch with the rope – the employee. Dyneema® ropes reduce the physical workload and the number of injuries due to its softness and low weight.

Further, the low elongation minimizes the risk of a backlash in case a mooring line breaks. High Performance Fiber ropes are an intelligent investment: The higher initial costs are amortized quickly and the investment pays back in multiple ways – lower total cost due to longer lifetime and lower maintenance and higher safety due to lower weight and easier handling.
