Why choose Dynamica Towing & Mooring ropes?

Dynamica Mooring ropes offer a lightweight, strong, and reliable solution for securing vessels safely in port or offshore. They are the preferred choice for all types of vessels - from the biggest container carriers, bulk carriers, navy, tankers, LNG vessels, ferries, barges, tug boats, fishing vessels to luxury yachts and smaller boats. Recommended for split drums winch applications. Not recommended for use on H-bits, capstans cleats.

Dynamica Towing ropes are engineered to deliver outstanding performance during demanding towing and tugging operations. They are the preferred choice for ships, tugboats and other vessels engaged in both harbour and offshore towing tasks.

Dynamica Mooring & Towing ropes are made with HMPE/Dyneema^® making them lighter, safer and just as strong as steel wire. Combined with their excellent abrasion and UV resistance, the ropes are ideal for a wide range of mooring and towing operations in wet and harsh maritime environments.

By choosing Dynamica Mooring & Towing ropes you gain:

Safe worksites
Low weight
Easy handling
Clean deck
Very high strength-to-weight ratio
Excellent fatigue life
Floats in water (depending on construction)
Less crew and heavy equipment for handling required
Resistant to most chemicals
No rust, long lifetime in the maritime environment
No need for grease/lubrication
High tension and bending fatigue resistance

Towing and Mooring rope construction

Dynamica Mooring & Towing ropes are manufactured with HMPE/Dyneema^® in a 12-strand braided construction. Besides this, your ropes can be constructed in many different ways e.g. with a braided or woven cover made either of heavy duty polyester or Dyneema^®. Both covers can get a final treatment with a Double Shield Coationg (DSC) which prevents abrasion, penetration of sand/mud particles and UV.

If used on high seas or with strong winds, it is recommended by OCIMF that the rope is fitted with nylon, polyester or mixed rope stretchers in order to absorb the shock loads.

Pennant

Our standard construction is a pennant with eyes with or without braided cover.

Thimble & masterlinks

Apart from the standard construction, Dynamica Mooring & Towing ropes can also be manufactured with customised solutions such as thimbles and masterlinks.

Elongation of Dynamica Mooring & Towing ropes

Dynamica Mooring & Towing ropes have a low elongation of only 3-4 %, which is similar to steel wire. For towing operations, this ensures more even tows. Thanks to their stiff construction, the ropes are also more comfortable and safer for the crew to handle.

Although we heat-stretch the Towing and Mooring ropes during production, you will experience elongation during initial use due to constructional elongation. However, after a few operations, the rope will become more length stable than their steel wire counterparts.

In case of breakage, the ropes' low mass and elongation results in the energy being distributed along the ropes’ entire length in a linear fashion. This results in a low and controlled recoil - unlike steel wire, which is known for lashing out and endangering people as well as equipment.

Do & don't

To ensure maximum strength and safety, it's important to handle your rope correctly during spooling. Avoid rotating the rope, as this can disturb its internal construction and reduce its strength - potentially leading to premature failure during use.

When the rope is not in use, always store it in a dry, covered area, away from direct sunlight and high temperatures. UV rays can gradually weaken the rope fibres, so proper storage helps preserve the rope's performance and extend its service life.

To further protect your rope from UV-degration and harsh weather, we recommend applying a high-quality, weather-resistant coating. This extra layer of protection is especially important for ropes used in marine and offshore environments, where exposure to sun, salt and moisture is constant.

Taking these simple precautions will help maintain the integrity, strength, and reliability of your rope - keeping both your crew and operations safe.

Braided and woven covers & jackets

How to protect Dynamica Towing & Mooring ropes

To extend the lifespan of Dynamica Towing & Mooring ropes, we recommend using a protective cover made of braided or woven HMPE/Dyneema^® or polyester.

The 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 in an agreed distance towards the middle of the rope
On the entire length

We always recommend covering the eyes and working ends, as these often are in contact with uncontrolled areas of service vessels or port facilities - areas where the crew has limited or no control.

Braided polyester cover

The braided polyester cover protects the rope against abrasion. It makes the rope non-floating, which is an advantage for some operations. On request, the cover can be treated with DSC.
