Gorgon Foundation Project

6 6

Runs through a three-train (15

million tonne per annum) LNG

and Domestic Gas facility on

Barrow Island.

It is the largest LNG plant ever

to be fed by a subsea system.

The Greater Gorgon Area

represents Australia's largest

known gas resource, estimated

to contain 40 trillion cubic feet

of gas – equivalent to 25% of

the country's total known gas

resources.

Subsea System

15

Subsea tie-back to Britannia Bridge Link Platform (BLP).

Subsea manifold containing:

− Two fully populated wellbays

− Subsea HIPPS

− Manifold mounted split Cooling loop

− Well and HIPPS SCMs

− Umbilical termination and distribution

− Chemical injection points (various)

Subsea structures “Fishing Friendly” / designed for required snag loads.

Subsea Manifold

Manifold piping and cooling spool

design

– Cooling loop made out of two “coils” -

for flexibility - self-draining

– HIPPS valves

– Production Valves

– Manifold piping orientated to meet

area subsea architecture

requirements, predominant current

direction, etc

– Interface with temporary Subsea Pig

launcher.
