A study by DSM Dyneema, a close partner of the liquefied natural gas industry, concluded that industry trends are changing the performance demands for mooring lines. Ropes with Dyneema—a low-weight, maximum-strength PolyEthylene fiber used in 50 percent of LNG mooring lines—are as strong as steel wire ropes of the same diameter but at only 1/7 the weight. Dyneema ropes are about 60 percent of the diameter and 30 percent of the weight of equally strong polyester or polyamide ropes. The lower weight of Dyneema-based ropes means reduced deckhand injuries. Moreover, in the unlikely event of a rope failure, ropes with Dyneema show no snap-back. Additionally, Dyneema fiber floats on water and is extremely durable and resistant to moisture, UV light and chemicals.
