Home' Ausmarine : October 2014 Contents September 2014 saw the Commonwealth
Scientific and Industrial Research
Organisation (CSIRO) welcome the
cutting-edge research vessel 'Investigator'
to its new home port of Hobart, Tasmania.
Designed by a North American
consortium of naval architecture and
engineering firms and constructed in
Singapore, the 'Investigator' is a highly
proficient research and survey vessel with an
extremely quiet operational capability. It will
serve Australia in diverse scientific operations
ranging over an area from the equator to the
Antarctic Southern Ocean.
The 'Investigator' has been designed to
handle the heat and humidity of the
tropics and the cold and ice of Antarctica.
The ice-capable vessel has also been
designed to meet the underwater-radiated
noise requirements of DNV's "Silent R"
notation up to a speed of eleven knots. This
feature will enable the 'Investigator' to
undertake environmental research in
highly sensitive marine areas.
On board, the vessel is fitted out with a
full range of scientific laboratories, science
and fishing winches, coring equipment, air
and water sampling devices, and acoustic
systems. It is c apable of ge neral-purpose
oceanographic survey operations in coastal
and deep ocean areas, as well as multi-
disciplin e e nvironmental in vestigation s ,
ocean engineering a nd marine acoustic s
surveys, coastal hydrographic surveys,
bathymetric surveys, and fisheries research.
The 93.9-metre x 18.5-metre x 5.7-metre
'Investigator' has a fully loaded speed of 15
knots in Sea State 2, a range of over 10,000
nautical miles, and an endurance of 60
days. Able to accommodate up to 60 crew
and personnel, including scientists, the
twin-screw vessel is powered by an
integrated diesel-electric propulsion and
ship service plant.
Classed by Lloyd's Register, the
'Investigator' is also fitted with a gondola
and two retractable drop keels to house an
extensive range of scientific sonar and
transducer suites. The vessel is also fitted
with a stern ramp to support fisheries
The "design and build" contract for the
construction of the 'Investigator' was
awarded to a team led by Teekay Shipping
Australia and a Singapore-based shipyard.
The vessel's design was developed by
RALion -- joint venture comprising
Canada-based Robert Allan Ltd and the
Alion Science and Technology (Canada)
Corporation, as well as Alion's Virginia,
USA branch. The contract was awarded to
this international team in 2011.
For further information contact:
The 'Investigator' is extensively equipped to perform the following tasks:
• Acoustic habitat mapping
• Acoustic surveys in support of bathymetric, geomorphological and biological research using a combination of hull-mounted, drop
keel mounted, and towed transducers
• Acoustic surveys of marine species
• Acquiring geological samples of the ocean bottom in depths of up to 5,000 metres
• Acquisition of benthic samples of the ocean bottom at depths up to 6,500 metres
• Acquisition of up to 30 metres of core samples of the ocean bottom at depths of up to 7,000 metres
• Bottom trawling to depths of up to 4,000 metres
• Conducting horizontal or oblique plankton tows over the stern or over the side of the vessel
• Conducting oceanographic sampling with rosettes of up to 36 bottles and CTD instrument packages to depths greater than 6,500
metres while continuously sounding
• Freeze and cold store samples for further analysis at shore-based facilities
• Launching/towing/retrieving a broad variety of active and passive sensors and sensor platforms including magnetometers,
hydrocarbon sniffers, sonar towfish, AUVs and UUVs
• Launching/towing/retrieving a variety of egg, larval, juvenile and adult fish sampling systems
• Marine mammal and seabird enumeration, identification, tracking, and bio assessment• Mid-water and surface trawling
