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 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.
