Gorgon Completes Drilling Campaign
The Deepwater Frontier drill ship has completed the final
Jansz-Io well and demobilised from the Project.
General Manager Major Capital Projects Kevin Shannon said
it was a significant milestone with all 10 wells at the Jansz-Io
field and eight at the Gorgon field ready to produce.
“The Jansz-Io drilling campaign was completed with an
impressive safety record – more than 540 days incident and

injury free,” Kevin said.
“This is a great accomplishment given the wells were drilled in
a water depth of 1,350m so the work required to connect the
rig to the seabed was particularly challenging.”
ExxonMobil, the Jansz-Io work operator, will officially
handover the wells to Chevron over the coming months.
Pre-commissioning Underway on Subsea Facilities
Pre-commissioning activities are
underway on the subsea facilities at the
Gorgon and Jansz-Io fields following the
installation of all 63 tie-in spools.
Upstream Facilities Project Manager
Milton Bruce said the spools were one
of the final components of the Project’s
subsea gas gathering system to be
installed, linking the wells and subsea
structures to the pipeline system.
“In simplistic terms, when all the
main structures that make up the gas
gathering system were installed we
measured the gaps between them
and fabricated spools to the specific
length required so we could connect the
system,” Milton said.
“With all spools installed and tied-in we
are now pressure testing the integrity of
the spool connections.”

Upstream Fast Facts
Jansz-Io Pipeline Pre-commissioning in Full Swing
With all onshore and offshore pipelines
installed and tested, pre-commissioning
activities are well underway on the
Jansz-Io pipelines.
Gorgon Upstream Facilities Project
Manager Milton Bruce said a series of
activities are preparing the pipelines
and associated infrastructure for the
introduction of hydrocarbons.
“Pre-commissioning provides assurance
that our pipelines, structures and
associated infrastructure are in good
working condition,” Milton said.
“The process involves cleaning to
remove debris, gauging to check
internal walls, flooding and hydrotesting
to confirm the operating pressure and
finally dewatering and drying before
packing the pipelines with nitrogen
to preserve them prior to operations
commencing.
“We recently completed dewatering the
three Jansz-Io pipelines – production,
monoethylene glycol and utility – from
the inlet area to the main subsea
structure, located around 140km
offshore.
“Our focus over the next few months
is to dry and prepare the Jansz-Io
pipelines so they are ready to be packed
with nitrogen and handed over to our
Operations team. We will then turn our
attention to pre-commissioning the
Gorgon pipeline system.”
Gorgon’s first LNG Train will be startedup with Jansz-Io gas.
The Project’s subsea gas gathering
system is located on the ocean
floor over the Gorgon and Jansz-Io
gas fields.
The Jansz-Io field is located
approximately 130km northwest
of Barrow Island in 1,350m of
water. The Gorgon field is located
approximately 65km west of
Barrow Island in 200m of water.
Subsea trees will contain and
control the production wells at
both fields. The produced gas will
be gathered at several manifolds
installed at each field and
transported via pipelines to Barrow
Island.
Both field developments are
supported by a feed gas pipeline,
monoethylene glycol injection
pipeline, utility pipeline and fibre
optic, electro-hydraulic control
umbilicals – a total of six product
pipelines and two umbilical casings.

The Downstream scope includes the design and construction of a three-train 15.6 million tonne per annum LNG
facility on Barrow Island and a domestic gas plant with the capacity to provide 300 terajoules of gas per day to
Western Australia. It also includes operations and accommodation facilities.
Domestic Gas Pipeline Ready to Import
Following the final connection at the jetty, the domestic gas pipeline is now connected from the mainland through to the plant site.
Gorgon Development Director Scott Young said pre-commissioning activities were also complete paving the way for gas to be
imported to start-up the first gas turbine generator (GTG).
“Starting up the first GTG will provide
the power to start commissioning the
various systems and facilities,” Scott
said.

“The BEAR system provides a safe
way of dealing with a situation where a
towline parts, leaving one barge adrift
while the other remains under tow.
It also eliminates the potential risks
associated with tug crews attempting to
manually release the anchor,” said Kent.
A total of 13 BEARs are now installed on
Project barges and Maritime Engineers
has been granted an Australian Patent
for the system.

Inlet Facilities Nearing Completion
Construction activities are progressing
on facilities in the inlet area, the entry
point for raw gas flowing into the gas
treatment plant from the two fields.
With all the major pieces of equipment
in position, work is well underway to
connect the individual components.
The current focus is completing the
construction of eight monoethylene
glycol (MEG) storage tanks and the
slugcatchers.
it acts as an antifreeze to absorb water
and prevent hydrates forming that could
block the pipelines.
MEG, which will be stored in the tanks,
will flow to the field in a separate
pipeline and back with the raw gas in the
production pipeline. MEG plays a critical
role in the transportation of the gas as
With several hundred people working in
the area it has been a great team effort
to carry out the work in a safe and
coordinated manner.
Operations Powering Up
The first members of the Operations
team have commenced commissioning
and monitoring systems in the Central
Control Room (CCR) on Barrow Island.
The CCR is located in the Project’s
Permanent Operations Facility and will
be used to oversee all aspects of plant
operation, including the gas treatment
and liquefaction process.
Barrow Island LNG Production Manager
Steve Pattrick said activities in the CCR
would continue to ramp up as Gorgon
progresses towards first gas.
“Technicians are commissioning the
fire systems and monitoring equipment
from the CCR. It’s a big step towards full
occupancy when the control panels will
be monitored 24 hours a day,” Steve said.

Key Focus on Mechanical, Electrical and Instrumentation Work
With Project execution activities now 90 percent complete, the key focus is the mechanical, electrical and instrumentation
(ME&I) work on Barrow Island.
Gorgon Development Director Scott Young said the ME&I work had ramped up following delivery in June last year of the final
module required to start-up the first LNG train.
“Essentially the ME&I scope involves all work activities required to connect the various components of the plant,” Scott said.
“As Barrow Island is a Class A Nature Reserve we fabricated the plant in smaller pieces offsite to minimise the impact on the
Piping and insulation work underway on the main
cryogenic heat exchanger for Train 1. LNG facility insulation
limits the impact of external temperatures on pipe and

island during the construction phase, before transporting them to Barrow where they are now being installed and connected.
“With most of the 51 modules and all 236 pre-assembled racks and units already installed, the profile of the plant site won’t
change much this year. However, significant progress is taking place on the ground to complete a wide-range of activities to
enable us to start-up the first LNG train later this year.
“This includes welding, pressure testing and painting activities, as well as installing cabling and insulation. In the next few
months there will be a change in the mix of skills required on site, with the focus of activity turning to the electrical works as
we move from construction to commissioning.”

Innovation Drives Efficiency
A Container Roll-Out Warehouse
System (CROWS) has been introduced
in the Barrow Island supply chain to
improve the efficiency of equipment
and material delivery.
that fit inside shipping containers.
Depending on the weight of the
materials stowed on the racks, they
can be stacked three high inside each
container.
The CROWS involves specially designed
inter-connectable cargo carrying racks
Once on site the racks are removed
from the container with a forklift and
stacked until the materials are required.
Materials and Logistics Manager Rob
Lowe said the island’s Class A Nature
Reserve status had created additional
challenges during construction.
“The State Agreement under which
Gorgon operates limits the land
available to the Project which means the
total construction footprint, including
laydown, is very small for a project of
this scale,” Rob said.
“The introduction of the CROWS has
increased storage space on Barrow as it
allows four racks to be safely stacked on
top of each other.”
The CROWS has been a collaborative
effort between Chevron, CB&I
Kentz Joint Venture and Sea Box
International.
Monitoring an
Environmental
Legacy
As part of the Project’s
commitment to protecting the
conservational values of Barrow
Island and its surrounding waters
more than 20 ongoing flora and
fauna monitoring programs are
undertaken.
Terrestrial Ecologist Andy Smith
said these programs helped to
verify that appropriate strategies
were in place to minimise Project
impacts on the environment and
the local fauna.
“It is pleasing to see our monitoring
results indicating our strategies are
working,” Andy said.
One of the primary purposes
for data collection is to estimate
population size to better predict,
monitor and manage potential
impacts associated with the
construction and operation phases
of the Project.

Flatback Turtle Tagging
Seabird Monitoring
Turtle tagging, one of nine marine
turtle-related monitoring programs, is
carried out annually during the nesting
season from November to January.
Surveys monitoring three seabird
species – the Bridled Tern, the Wedgetailed Shearwater and the Silver
Gull – are carried out on Barrow and
surrounding islands.
Undertaken on the beaches of
Barrow Island and Mundabullangana
– a reference site located west of Port
Hedland – teams of volunteers tag,
measure and collect data on the nesting
turtles.
The 2014-15 season marked the tenth
year of the program which has seen
more than 700 volunteers tag and
measure more than 9,000 turtles.
In the previous two surveys more

Gorgon was recently awarded a national Engineering
Excellence Award by Engineers Australia for the JanszIo Subsea Pipeline Scarp Crossing.
Gorgon Upstream Facilities Project Manager Milton
Bruce (second from left) said winning the award capped
off close to 10 years of detailed research, planning and
execution activities.
“Accessing the Jansz-Io field required crossing an
underwater escarpment at the edge of the continental
shelf where the water depth goes from 500m at the top
down to 750m. Typically subsea pipeline span lengths
are in the order of 40m. However, the steepness of the
scarp route resulted in the design of 270m long spans,”
Milton said.
At the end of last year the Salvation Army received a
much needed boost to its Christmas Appeal following a
$10,000 donation raised from ticket sales to Gorgon’s Got
Talent.
Gorgon’s Got Talent has been held annually since 2009
to showcases the hidden talents of those working on the
Project. Each year the winner selects a charity of their
choice to donate $10,000.
