Strength is an essential feature in mooring lines – especially given the extreme conditions LNG carriers usually operate in. Strength isn’t just crucial to commercial success, but also to the safety of crew members and port workers
Para-aramid fibers Twaron® and Technora® provide full confidence in your mooring lines’ strength. These fibers are proven to provide maximum durability and reliability – particularly at the elevated temperatures and UV levels of Qatar, Australia, and other typical regions for LNG operation
Independent rope testing authority TTI confirmed this strength performance, testing Twaron®-and Technora®-based mooring lines against HMPE ropes at typical LNG-carrier temperatures. The tests assessed strength, tensile performance, and creep resistance.
The aramid-based ropes consistently outperformed HMPE ones (download full article here), with particularly noticeable differences at higher temperatures. In particular, at 50°C and 70% minimum breaking load, the aramid samples survived for 100 hours. In contrast, the HMPE ropes failed after only 10 minutes under these conditions
Aramid-based ropes also deliver superior strength under prolonged UV exposure. Since mooring lines are commonly used in regions with high UV levels, this is a particularly important advantage.
When exposed to extreme levels of UV light at Teijin Aramid’s Research & Innovation Center, braided aramid-based ropes outperformed HMPE-based ropes (download full article here). Specifically, all the aramid ropes retained full strength even after 1,000 hours of UV exposure – and some retained strength for up to 4,000 hours.

From these results, it’s clear that aramid is the strongest mooring solution for LNG carriers operating in hot, sunny climates.
