At the recent Subsea 2012 conference in Aberdeen, First Subsea's Brian Green presented a new perspective on the mooring challenges facing oil and gas operators as they develop fields in deeper waters in his presentation 'Deepwater Mooring – Going Deeper, Getting Leaner'.
Deeper moorings can take longer to deploy and require more boat time. The 'Lean Installation' concept for the deployment of deepwater moorings is intended to reduce the time (and cost) of deepwater mooring deployment, yet improve the integrity of the moorings. The presentation describes the application of Lean Installation as a framework for future mooring technology developments. It also reports on First Subsea and the University of Sheffield's collaboarative research into the manufacture of large scale, steel forgings, and the development of mooring in-line connectors and new approaches to pre-loading deepwater mooring lines as examples of Lean Installation.
