The introduction of new and larger vessels, Q-Flex and Q-Max, and new, often more exposed terminals becoming operational have changed mooring dynamics. The need to maintain workers’ safety at all times, whilst delivering maximum operational efficiency through lower costs and faster turnaround times remains unchanged. DSM Dyneema, a close partner to the LNG industry, has done a study which concludes that these industry trends are changing the performance demands for LNG mooring lines. In parallel to DSM Dyneema’s investigation, in 2011 members of the LNG community created a Users Group to further investigate HMPE mooring line failures which TTI (UK) was asked to facilitate. DSM Dyneema is part of the Users Group, while at the same time continuing its own investigation program.
