Aurora Australis was an Australian icebreaker. Built by Carrington Slipways and launched in 1989, the vessel is owned by P&O Maritime Services. It was regularly chartered by the Australian Antarctic Division (AAD) for research cruises in Antarctic waters and to support Australian bases in Antarctica.

Design and construction

Designed as a multi-purpose research and resupply ship, Aurora Australis was built by Carrington Slipways in Tomago, New South Wales. [2] The vessel was launched in September 1989. [2] [3]

Aurora Australis is 94.91 metres (311.4 ft) long, and has a beam of 20.3 metres (67 ft), draught of 7.862 metres (25.79 ft) and moulded depth of 10.43 metres (34.2 ft). Her displacement is 8,158 tons, gross tonnage 6,574 and deadweight tonnage 3,911 tons. [2]

Her propulsion machinery consists of two Wärtsilä medium-speed diesel engines in father-son arrangement, one 16-cylinder 16V32D producing 5,500 kW and one 12-cylinder 12V32D producing 4,500 kW. Both engines are coupled to a single shaft through a reduction gear, driving a single, left-hand-turning controllable-pitch propeller. [4]

Slow speed manoeuvring is achieved with three manoeuvring thrusters, one forward and two aft. [4] Aurora Australis has a maximum speed of 16.8 knots (31.1 km/h; 19.3 mph),[ citation needed ] and a cruising speed of 13 knots (24 km/h; 15 mph). [2] The vessel can break level ice up to 1.23 metres (4 ft 0 in) thick at 2.5 knots (4.6 km/h; 2.9 mph). [2] [5]

Aurora Australis had a crew of 24 [5] and could carry up to 116 passengers accommodated in three or four-bunk cabins with attached bathrooms. [2] [6] The ship has a cargo capacity of 1,700 cubic metres (60,000 cu ft) for break bulk or 29 twenty-foot equivalent containers, and a supply tank that can hold 1,000 cubic metres (35,000 cu ft) of fuel.[ citation needed ] The ship is fitted with laboratories for biological, meteorological, and oceanographic research, and was designed with a trawl deck for the deployment and recovery of research instruments while at sea. [2] The ship's hangar and helideck allow for the operation of up to three helicopters, [2] usually Eurocopter Squirrels or Sikorsky S-76s.[ citation needed ]

Operations

Aurora Australis was chartered by the AAD over the southern summer for research purposes, and to support the Antarctic bases operated by the AAD. [6] The vessel spent most winters in port in Hobart, as the AAD headquarters is in the nearby town of Kingston.[ citation needed ] P&O sometimes chartered the ship for other work during winter.[ citation needed ]

On 8 May 2011, Aurora Australis was chartered by the Department of Defence for a two-month deployment, ending 30 June, as an amphibious transport ship supporting the Royal Australian Navy. [6] The charter, costing A$3.375 million, was to assist in the Australian government response to humanitarian crises and natural disasters that occurred while the naval heavy lift ship HMAS Tobruk underwent maintenance. [6]

In late December 2013, Aurora Australis, Chinese research vessel Xuě Lóng and French icebreaker L'Astrolabe attempted to rescue Akademik Shokalskiy , which had become stranded in thick Antarctic ice in Watt Bay. [7] [8] None of the three ships were able to reach the Russian icebreaker, with Aurora Australis aborting efforts on the morning of 30 December, due to the risk of the ship also becoming stuck. [7] [8] On 2 February, the 52 passengers from Akademik Shokalskiy were transported by helicopter to Aurora Australis by Xuě Lóng's helicopter, the Chinese icebreaker having become trapped as well. [9] After the rescue, Aurora Australis continued on her original mission to resupply Casey Station, before returning to Hobart on 22 January. [10] [11]

The Aurora Australis returned from its final voyage in March 2020. After 31 years of service to the Australian Antarctic Program, the last trip was a two-week voyage to resupply Macquarie Island and transport expeditioners to the south. Suggestions have been made that the ship could be used as an emergency vessel if acquired by the Australian Government. [12] Another possible use that was suggested for the ship was as an Antarctic-themed museum berthed in Hobart. A not-for-profit organisation, the Aurora Australis Foundation, was established to explore this option. However, by June 2020 it looked like the most likely outcome for the Aurora Australis was to be sold to the Government of Argentina for further Antarctic deployment. [13] [14]

Engine Room Fire

At 2.25am on 22 July 1998 whilst en route to Antarctica a fire broke out in the engine room. The researchers were on the first winter voyage to the Antarctic, a seven-week expedition to explore, the Mertz Glacier Polynya. [15] [16]

On 14 January 1999 whilst en route to Antarctica a fire caused by leaking high pressure diesel igniting on the hot STBD main engine caused a major fire. The fire resulted in zero visibility in the engine room and was suppressed by the release of halonium ion fire suppression system. Re-entry to the compartment resulted in successful restoration of power and propulsion to the ship and it returned to Fremantle under its own power for an investigation by the Australian Transport Safety Bureau and major repairs. [17]

Grounding

On 24 February 2016, the vessel was damaged when it ran aground in Horseshoe Harbour, near Mawson Station, Antarctica, during a blizzard, after a shackle on a forward mooring line came undone, causing the other three lines to break. It was refloated on 27 February 2016 and returned to Western Australia for repairs. [18] [19] [20]

Replacement

In October 2015, the Australian government announced a plan to acquire a new icebreaker to replace Aurora Australis by 2019. [21] Nuyina entered service in 2021. [22] [23]

Aurora Australis was decommissioned in 2020, amid attempts to retain the vessel in Hobart as a floating museum. [24] Although these efforts were unsuccessful, the ship's tender, Aurora Australis II, was acquired by the Aurora Australis Foundation with the aim of making it the centrepiece of an Australian Antarctic Museum. [25]

The Australian Antarctic Division (AAD) is a division of the Department of Climate Change, Energy, the Environment and Water. The Division undertakes science programs and research projects to contribute to an understanding of Antarctica and the Southern Ocean. It conducts and supports collaborative research programs with other Australian and international organisations, such as the Bureau of Meteorology and Geoscience Australia, as well as administering and maintaining a presence in Australian Antarctic and sub-Antarctic territories.

Casey Station, commonly called Casey, is one of three permanent stations and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Casey lies on the northern side of the Bailey Peninsula overlooking Vincennes Bay on the Budd Coast of Wilkes Land in the Australian Antarctic Territory, a territory claimed by Australia. Casey is 3,880 kilometres (2,410 mi) due south of Perth, Western Australia.

<span class="mw-page-title-main">Australian Antarctic Territory</span> Australian territorial claim on East Antarctica

The Australian Antarctic Territory (AAT) is a part of East Antarctica claimed by Australia as an external territory. It is administered by the Australian Antarctic Division, an agency of the federal Department of Climate Change, Energy, the Environment and Water. The territory's history dates to a claim on Enderby Land made by the United Kingdom in 1841, which was subsequently expanded and eventually transferred to Australia in 1933. It is the largest territory of Antarctica claimed by any nation by area. In 1961, the Antarctic Treaty came into force. Article 4 deals with territorial claims, and although it does not renounce or diminish any pre-existing claims to sovereignty, it also does not prejudice the position of Contracting Parties in their recognition or non-recognition of territorial sovereignty. As a result, only four other countries — New Zealand, the United Kingdom, France, and Norway — recognise Australia's claim to sovereignty in Antarctica.

A research vessel is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters.
