Mooring integrity is an important concern in the offshore industry [1]. Mooring leg failures can have  significant consequences, such as temporary shutdowns and require unplanned, thus expensive, repairs. On the other hand, an over dimensioned design leads to higher loads acting on the floating facilities and a large investment. Meanwhile, the development of deepwater projects has led to the discovery of the new fatigue mechanism of ‘Out of Plane Bending’ [2]. This means that the design of moorings requires more detailed analysis to ensure the integrity of the mooring system.

LNG Mooring Lines Made with Dyneema

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.

Mooring Safety Improved at Port Taranaki

Scotload, part of James Fisher and Sons plc, has designed and delivered a solution for the monitoring of mooring line stresses at Port Taranaki, a deepwater port in New Zealand. The company said it utilized its SmartLoad 2Ex technology for Zone 2 hazardous areas to improve safety and significantly reduce the risk of mooring incidents. Port Taranaki has a long history of mooring difficulties and experiences long period waves (LPW) which excites the motion of moored vessels, increasing the loadings and the possibility of breaking the mooring lines.
