Cost Competitive cost in number of areas

Environmental Strong environmental lobby amongst local communities against

onshore facilities (e.g. US East Coast, California, Baja California,

Italy) No environmental impact on shore line

Security and safety Remote from inhabitants, hence consequences of accident

limited Contain or lower risk arising out of terrorist threat post 9/11

Regulatory

Planning / permitting may be shorter for offshore facilities In the US for example, permitting for offshore facilities falls under

US Coast Guard rather than FERC. US Coast Guard decisionsmade within a year

A floating LNG receivingterminal is hard to notice

from shore.

Typical land-based terminal

Break-water and turning basin required

Potential LNG FSRU

LNG FSRU - WHY?

The NIMBY* and BANANA* issues can be handled!

* NIMBY - Not In My Back Yard* BANANA - Build Absolutely Nothing Anywhere Near Anything

A company of

LNG FSRU - WHAT IS IT?

The FSRU is a steel mono-hull with:

LNG storage tanks

Re-gasification plant

Crew facilities with control room and utility machinery

Moored with an external turret, soft yoke arrangement or STL

for free weather-vaning

Gas send-out line arranged through the mooring system downto the seabed and from there directly to the shore manifold

LNG Carriers berthing side-by-side for offloading

MOORING

A company of

The sloshing phenomena occur when theship motions coincide with the natural

frequency of the liquid motion in the tanks.The build-up of violent motion is due to

frequency, not amplitude.

The sloshing phenomena takesplace in partially filled tanks.

A floating LNG Terminal is

always partially filled.

SLOSHING PHENOMENA

No problem.

The FSRU will be designed and built to minimize harmful effects on the local environment:

Use of gas instead of oil for power generation (zero particle- and SOx emissions) No flaring of gas during normal service Complete on-board sewage treatment Complete on-board waste compacting or incineration plant No chemical effluents

NORMAL EMMISSIONS AND RELEASES

Exhaust gas from power generation Seawater for regas plant (4 MMTPA)

(normal water circulation 10,000 tons/h, temperature reduction 6.5 C)

ACCIDENTAL EMISSIONS AND RELEASES

Cold vent of natural gas (in case of system de-pressuration)

LNG spillage during loading operation

A company of

Offshore LNG facilities technology has matured to a point where itenables the jump from traditional onshore to offshore facilities

Floating (FPSO/FSRU) and fixed (GBS) structures, using eithersteel or concrete hull

Wealth of knowledge from the now mature oil FPSO sector whichcan be transferred to FPSO/FSRU LNG facilities design and operation

FRSUs currently in approval phase (Livorno, Cabrillo Port,Baja California)

LNG carrier technology knowledge transfer

GBS concrete receiving terminals are currently under FEED stage(Rovigo, Pelican, Baja California, Gulf of Mexico)

Cryogenic storage well understood and integration not major issue
