Home' Asia Pacific Defence Reporter : APDR October 2016 Contents occurred in preparing the future Hobart AWD for sea
trials. By February this year, the combat systems and
test activities had come alive, then in April the first main
engine was started, and by late July the gas turbines
had been tested.
A status report from the AWD Alliance announced
that Hobart was 97% complete, which is for the whole
of ship as at the end of August. At 9.20am on 12
September 2016, the future AWD Hobart departed
the wharf at Techport Adelaide for the first time to
commence several days of shipbuilder Sea Trials off the
coast of South Australia. Lloyd Beckett said to APDR:
“Hobart’s Builder’s Sea Trials represents a decade
of dedication and effort, and millions of hours of work,
by the AWD workforce on one of the most complex
shipbuilding projects in Australia’s history.”
This first phase of trials is designed to test the ship’s
hull, propulsion and navigation systems. A second
phase of more advanced CAT5 trials will take place
in early 2017 when Hobart tests its combat and
The commencement of sea trials is a significant
milestone for the AWD project and a major step
towards delivery of the most capable warships ever
operated by the RAN.
In February the AWD Alliance announced ‘Combat
system compartments, such as the Combat System
Equipment Rooms, the Combat Information Centre and
the radar equipment room, are filled with personnel and
activity as equipment is powered on for the first time
and functionally tested.
‘Support teams have been in the shipyard supporting
the activation of systems including elements of the
distributed navigation system and the Vertical Launch
‘The Multi Element Integration & Test (MEIT) team
successfully completed the first phase of activation
activities. This significant achievement involved the
installation of the Aegis Software Operating Environment
and the activation of the computer network structure.
Activation has also started on the MK99 Fire Control
System and the SPY1D-(V) phased array radar.
‘In addition, the teams have prepared and powered
up all mission critical enclosures and CIC consoles
whilst also completing the integration of the Navigation,
Infra-Red Search & Track sensor, Electro Optical Sensor
and Typhoon with the Australian Tactical Interface (ATI).’
Early June saw the last of three visits from the US
based MEIT, who were responsible for activation of
some of the Combat System equipment in February,
the installation and checkout of the Tactical Aegis
computer program in March and the recently completed
activity of working through the Aegis Combat System
interfaces to validate functionality.
The Combat System team has completed
approximately 85% of their scope of work. 90% of the
combat system interfaces are now verified.
Meanwhile work had been going on bringing the
propulsion system to life. In April the AWD Alliance
reached another major milestone in the lead up to
sea trials for Hobart with the commencement of ‘Main
Engine Light-Off’ - or starting of one of the main
engines that will drive the ship’s propellers.
July saw months of hard work from Production
and Test and Activation resulting in the successful
commissioning of the AWD Gas Turbines on Hobart.
Prior to departing for Builder’s Sea Trials on 12
September numerous alongside dock trials were
conducted including incline trials to measure the ship’s
stability and vertical centre of gravity, main battery
alignment to ensure elements of the combat systems
are correctly positioned and aligned, and bollard trials
to test the ship’s propulsion system.
PROGRESS WITH SHIP 2 - BRISBANE
Brisbane is 84% complete (whole of ship as at August
2016), and is preparing for launch in December 2016
with the planned completion of prerequisite work
including shore power through the ship’s switchboard,
commencement of the ship’s Integrated Platform
Management System (IPMS) and underwater hull paint.
Over 40% of combat systems equipment on Brisbane
has now been installed. Over the past two months, load
out of combat spaces such as Command Information
Centre, Combat System Equipment Rooms, Direct
Support Element Operations, and Communication
spaces has occurred in addition to the successful
installation of the last of the ship’s four AN/SPY-1D(V)
Phased Array Radars.
All ships are benefitting from lessons learnt from
Ship 1 with significant efficiency gains being measured
from the first ship to the second and third ships, for
example: The Ship 2 team halved the amount of time
taken to load-out the final AN/SPY-1D(V) Phased Array
Radar. The first SPY Array installation on Ship 1, some
18 month ago, took 12 hours, while the last one was
completed in August in less than six.
With a timeline of only eight months to complete the
installation of the Propulsion Shaft Line on Ship 2, the
Shafting Team has been highly effective in evaluating
and implementing lessons learnt from the Ship 1
installation, a process which previously took 12 months
The AWD is propelled by two shaft lines, port and
starboard, each coupled to a Main Reduction Gearbox
powered by either a diesel engine or gas turbine.
Of the four phase installation process, the Shafting
Team gained significant efficiencies in the Phase Two
process where the shaft is pulled into the ship using
a Tractel Tirfor manual winch system. This amazing
system has no limitation in terms of cable length and
allows precise load placement within millimetres.

Both Brisbane and Sydney are benefitting from the lessons being
applied from Hobart, with significant efficiency gains being
measured from the first ship to the second and third ships.
