Agenda
Safety, Excellence, Innovation, Teamwork, Transparency 3rd of December, 2012. Rotterdam
Several configurations can be envisioned
Membrane tanks and 9%Ni are the safest designs
Above ground is the most economical configuration
Typical configurations
Above-ground Semi-buried Inground Cryogenic
cavern
Single
containment Double
containment
9%Ni
Full Containment
Membrane
Full Integrity
Largest footprint Easiest and fastest to built
In case of failure, LNG is contained by a dik
In case of failure, LNG is contained by a bund wall
Mostly used nowadays
In case of failure, both LNG and NG are contained by the concrete walls
Most compact & economical design
In case of failure, both LNG and NG are contained by the concrete walls
Full Integrity storage types (safest designs) Non-Full Integrity storage types
Land storage tank options
Safety, Excellence, Innovation, Teamwork, Transparency 3rd of December, 2012. Rotterdam
Single Containment
Large tank spacing
Greater safety distances to public
Larger site area required
Cheaper design but very difficult to get approval by local authorities as safer design are available
Safety, Excellence, Innovation, Teamwork, Transparency 3rd of December, 2012. Rotterdam
Double Containment
Closer tank spacing
In case of failure, LNG is contained by a bund wall
Bund wall much closer to primary container
Not cost advantage & less safer than Full integrity systems (9%Ni & Membrane)
Safety, Excellence, Innovation, Teamwork, Transparency 3rd of December, 2012. Rotterdam
9%Ni Full Containment
Full Integrity system :No bund wall required
In case of failure, both LNG and NG are contained by the concrete walls (safest design)
Mostly used nowadays
Safety, Excellence, Innovation, Teamwork, Transparency 3rd of December, 2012. Rotterdam
Membrane Full Integrity
Full Integrity system :No bund wall required
In case of failure, both LNG and NG are contained by the concrete walls (safest design)
Very popular for inground and high seismic areas.
Safety, Excellence, Innovation, Teamwork, Transparency 3rd of December, 2012. Rotterdam
9%Ni Full Containment
Membrane Full Integrity
Safest designs: What are the technical challenges?
Tank size is limited by thickness of 9% Ni steel plate
Not well adapted for harsh seismic environment
Not adapted for fast track solution
Room for innovation is very limited; the technology
has reached its maturity phase
No limitation of capacity
Well adapted for harsh seismic environment
Significant feedback from LNG tanks and Huge feedback from Membrane LNG carrier in more severe conditions
Cost & Schedule saver
No technical challenges for Membrane ???
So why no Membrane tanks have been recently built?? Answer at the end of the presentation

What should be the tank proper capacity?
Facts: Conventional LNG terminals are considering 160K LNG Tanks capacity This is suitable for 147K LNG carriers.
But LNG carriers size is increasing:
New range of conventional LNG carriers: between 155K to 170K
31 LNGC of Qflex type: (210K-217K)
14 LNGC of Qmax type: 266K
WHY NOT INCREASING THE SIZE OF LNG STORAGE TANKS?
2 Q-Max and 2 Q-Flex vessels

GST® Membrane : A Very Flexible Technology
Safety, Excellence, Innovation, Teamwork, Transparency 3rd of December, 2012. Rotterdam
Ease of Tank Design with GST® Membrane
Tank Design is optimized with this patented innovative arrangement.
With only 2 differently shape elements, 95% of the tank’s surface can be covered.
Membrane is suitable to harsh seismic conditions (no need of complicated anchors:
Cost & construction schedule savings)
Membrane is a very flexible design: no theoretical limit to tank capacity.

• Materials are easily available with several suppliers in Europe and Asia.
• With a standardized production, membrane allows significant procurement cost savings.
• Membrane allows to have a faster production time: around 3 weeks for the main components (based on a typical 160K).
• Most of the components of the membrane technology can be locally produced.
Ease of Procurement with GST® Membrane
Safety, Excellence, Innovation, Teamwork, Transparency 3rd of December, 2012. Rotterdam
With membrane, almost all components are prefabricated:
• Limited operations on site.
• 40% less welding time compared to 9% Ni.
• Light handling equipment (no crane inside the tank).
• High ratio of Local Workmanship
At least 3 to 4 months saving compared to conventional 9%Ni tanks
