Mooring Ropes

Dyneema®

View Details

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.

What makes a good mooring line?

An important feature of a good mooring line is a high degree of elongation. If the mooring line doesn't have a certain degree of elongation, the movement of the boat caused by wind and waves puts unhindered force on the cleats or grommets on which the rope is fastened to. A mooring line absorbs this kinetic energy, which not only prevents possible damage, it also makes the time spent on board more pleasant. Similarly, a mooring line must have a high breaking force to be able to secure the boat, even in stormy weather and heavy swell. The necessary breaking force depends on the size of the boat. We recommend always being generous when considering breaking force, as even slight chafing will weaken the rope considerably - and there are plenty of places where mooring lines can chafe, such as on fairleads, chocks etc. Mooring lines should therefore be robust. They should also have good flexibility and grip, so that managing the lines, coiling and making knots or splicing is easier. Finally, UV resistance is important. Mooring lines which are left permanently at the berth should not be allowed to become porous or brittle.
