ICEBREAKER
ALTE. IRIZAR

A journey through the history, reconstruction and modernization of the flagship of the Argentine naval force.

THE HISTORY

Where And When Was It Built?

The ARA Almirante Irízar (Q-5) (RHAI) icebreaker, which belongs to the Argentine Navy, was built in 1977 at the Wärtsilä Shipyards in Helsinki, Finland. On December 15, 1978, it was delivered to the Argentine Republic and it received the National Pavilion. Her godmother was Mrs. María Celia Villanueva de Fraga. In March 1979, Tandanor awarded it with its war flag. Since then, it has participated, year after year, in the supply of the Argentine Antarctic bases, and of other countries, and it is the flagship of the Antarctic Naval Force.

Worldwide Recognition for Performance in Antarctic Missions

AS A HOSPITAL VESSEL

During Malvinas War, it joined the “Task Force 40” along with other navy’s vessels. It participated in tactical operations transporting troops and divers to different areas. On June 3, 1982, it was decided to transform the RHAI into a hospital vessel, a task for which it was conditioned at the “Puerto Belgrano” Naval Base with the provision of 160 hospital beds, an intensive therapy room, operating rooms and other health facilities. Afterwards, it was subsequently sent to the Malvinas Islands, where it operated as a hospital vessel until the end of the conflict.

AS A RESCUE VESSEL

In 2002, it was sent on the difficult rescue mission of the German polar transport vessel Magdalena Oldendorff, which was serving the Russian base of Novolazarevskaya and, at a temperature close to -50 ° C, was trapped in the Antarctic winter without being able to move through the frozen sea. The RHAI, breaking over 330 km of ice, supplied the german vessel with medicine, fuel and food. In 2012, the Argentine Mail issued a stamp commemorating the tenth anniversary of the Operation Cruz del Sur.

AS A REFURBISHMENT VESSEL

Usually, between mid-spring and autumn, the RHAI participates in the Antarctic Campaigns. By using the Ushuaia Naval Base (BNUS) as its own refueling point, it goes to the bases that the Armed Forces of Argentina have in the white continent, restocks them, collects the waste they produce and transfers the replacement staff. Generally, there are different stages established in which the vessel returns to the BNUS to complete its replenishment and then it crosses the Drake Passage again.

AFTER THE ACCIDENT

WHAT TO DO?

JUNE 2008 - FEASIBILITY STUDY

Commissioned by the Ministry of Defense of the Nation, this study was carried out with the objective of evaluating different alternatives. The Technical Commission was made up of: personnel from the commissioning Ministry, the Ministry of Economy and Production, the Mayor General State of the Navy, the General Directorate of Naval Material, the National Directorate of Antarctica and the Department of Naval Engineering of the Faculty of Engineering of the UBA.

ALTERNATIVES EVALUATED

There were 18 and they included the following items:

RECONSTRUCTION AND MODERNIZATION OF THE ICEBREAKER

The project includes the delivery of a new icebreaker vessel with modern equipment and a performance superior to the previous one.

WHO IS GOING TO REPAIR IT?

CINAR

The reconstruction of the Almirante Irizar icebreaker in the Argentine Naval Industrial Complex (CINAR) was a decision based on two complementary dimensions.

RECONSTRUCTION AND MODERNIZATION OF THE ICEBREAKER ALMIRANTE IRÍZAR

The reconstruction and modernization of the Almirante Irizar Icebreaker did not pretend that at its conclusion the icebreaker would be exactly as the old Irízar, on the contrary the Project pursued a  reconstruction and modernization that could allow the delivery of a new icebreaker vessel with modern equipment and superior performance to the previous (even above the icebreakers available on the market: habitability, load capacity, laboratory capacity, among some other relevant aspects).

The reconstruction of the Almirante Irizar icebreaker in the Argentine Naval Industrial Complex (CINAR) was a decision based on two complementary dimensions:

  1. I) promote the development of the argentine naval industry; and
  2. II) safeguard the economic efficiency in the administration of public resources.

In the first dimension of the ones exposed, the Irizar project enabled the development of new capacities within the national industry. Specifically in the case of CINAR, the project promoted the generation of new working positions and new knowledge and skills both in the infrastructure of the shipyard facilities and in the training of human resources at all levels, with special emphasis on the direction and management of highly complex naval projects that involve planning, engineering, monitoring and development of a logistics system from a wide spectrum of national and foreign suppliers. Today, this allows CINAR to position itself as a competitive shipyard at a regional level, both in the repairment segment and, especially as a result of this project, in the construction market.

Indirectly, the project promoted the development of national providers of industrial services linked to the construction of equipment and facilities as well as national providers of services linked to the assembly of equipment and facilities, generating a significant number of indirect employment that is added to the ones of CINAR.

Regarding the second dimension of the ones exposed, linked to the economic efficiency in the administration of public resources, there are two aspects to consider:

  1. a) the lower cost associated with the reconstruction and modernization of the icebreaker in the country compared to the acquisition of a new icebreaker built abroad; and
  2. b) the saving in terms of foreign currency and safeguarding reserves.

According to the first point, the construction of icebreakers is carried out at the request of the client based on the specifications established by this one. It is a process that implies the immediate non-availability of the vessel as there are no products that are worked in series production with available stocks . The possibility of quickly having a new icebreaker for the 2009/2010 season was unfeasible from the point of view of availability in the icebreaker market, taking into account that this type of vessel is mostly owned by countries that use it to carry out their campaigns in the Arctic and Antarctica, an activity considered strategic.

In this sense, the incorporation of an icebreaker with characteristics and benefits similar to the new Almirante Irizar icebreaker is a process that requires between 5 and 7 years considering the times of specification of folders, bidding, evaluation of offers, vessel’s design and the construction itself (these times are proportional to the characteristics of the ship to be built depending on the requirements and specifications of the client). For this reason, even under a scenario where the purchase of a new icebreaker built abroad would have been chosen, the rental of resources for the Antarctic Summer Campaign 2009/2010 and others would have been necessary inevitably .

As a reference, it can be mentioned the Agulhas II icebreaker by the STX firm in Finland. The project had the contract signing date in 2009 and the finalization of the construction in 2012. It had a cost of USD 175 million, being a vessel with characteristics and a performance inferior to those of the new Almirante Irizar icebreaker, in terms of capacities considered important based on the requirements of the Antarctic campaign: bigger crew capacity (100 Agulhas II vs 313 new Irizar), greater fuel supply capacity to the bases (500 m3 Agulhas II vs 650 m3 new Irizar), a 50% higher power (12,000 KW Agulhas II vs 18,000 KW new Irizar),  better capacity in laboratories, just to mention some relevant points.

Therefore, taking as a reference the mentioned vessel contemporary to the Irizar Project in its construction period (although smaller in size and performance than the Irizar), it is obvious that under a scenario of acquisition of a new icebreaker ship abroad, this one would not have been available at least until 2014 (considering 5 years from the design of the specifications until the vessel’s delivery). This would have led to the fact that the first campaign to be carried out with our own vessel would have been 2014/2015 (in an optimistic scenario).

In addition, to carry on the reconstruction in the country also meant a complementary fiscal saving through the tax collection that was generated as a result of the project (invoicing of national companies and employment).

Finally, in relation to the saving of foreign currency and safeguarding reserves, the reconstruction and modernization alternative of the Almirante IrÍzar icebreaker in the country represented a significant saving in foreign currency as the imported content of the work was 36%.

IMPROVEMENTS

Multipurpose Ship

Transformation of the icebreaker into a multipurpose vessel: scientific with the latest technology without losing its characteristics as an Antarctic logistics and rescue vessel.

Increased Capacity For Research And Laboratory Sector
Laboratories are 6 times larger than the ones in the original configuration, from 74 m2 to 412 m2. Before the ship had a single laboratory but today it has 8 ones equipped with the latest technology.
Expansion of the Passenger Transport Capacity
Expansion of the capacity to transport passengers with a smaller crew: from 250 to 313 people.
Integrated Command Bridge
New control bridge fully integrated to all systems.
Control And Monitoring System
Complete automation from 2,000 to 5,000 control points, which allows monitoring and operation of the vessel from a single point. The installed technology implies a technological leap of 6 generations.
Total Reconstruction Of Habitability
The habitability was entirely rebuilt: there are 203 places, 83 correspond to cabins with different capacities. Approximatly 4,000 m2 of floors, the same amount of ceilings, and 12,000 m2 of dividing bulkheads, wich is similar to a building with 8 complete floors.
Power Generation System
4 main motor-generators of 4,500 kW MAN. 3 Auxiliary Moto-Generators of 640 kw MAN. 1 Emergency motor-generator of 340 kw. Renewal of all medium and low voltage wiring, aft of the frame 84.
Power Plant
Increase of 10% in the power with 2 new electric propulsion motors (ABB) of 6,500kw. Change of the electric drive system from 660 v direct current to medium voltage 3300 v alternating current. New hydraulic couplings for both axle lines.
Navigation And Communications
Two new air navigation radars: the primary one traveled and repaired by CITEDEF and the secondary one new and manufactured by INVAP.
Environmental Care
Plant for the treatment of dirty water adapted to the new endowment, garbage treatment equipment, incinerator, compactor and glass breaker approved by DNV to comply with all the latest resolutions of the IMO Pollution Control and Environmental Protection Committee, MARPOL, Antarctic Treaty and Madrid Protocol.
Navegación Segura Secure browsing
New fire detection system, flight deck foam system, water mist system on diesel engines and boilers. CO2 system in dangerous machinery spaces and warehouses. Gas detection system in confined spaces and pump rooms of GOA and JP1. Adequacy of structural protection insulation in bulkheads and decks to comply with the requirements of SOLAS and DNV.
Salvamento Y Evacuación Salvage And Evacuation
Lifeboats: two for 85 people each and two life and rescue boats for 73 people each. Four life rafts with capacity for 20 people each. Replacement of self-supporting bulkheads with steel bulkheads to achieve the required escape routes on deck 01. Change of exterior doors for new ones of greater width. General modifications to fire-resistant hallways, stairs, and doors.
Bubble System
Installation of a new bubbling system and new air compressors. When the vessel is beached on the ice the bubbling system causes it to produce a “back and forth” movement that initiates the ice fracturing, allowing its release.
Flight deck
The flight deck area is increased and the necessary modifications are made to adapt it to the needs of ARA and the international regulations of DNV, ICAO, SOLAS, meeting requirements for refueling and ship safety. Installation of a heating system in the hangar to avoid freezing of the take-off and landing areas.
GOA & Freight Transportation
Increase in the transport capacity of GOA (Antarctic Gas Oil): from 350 m3 to 667 m3 and modifications so that the GOA system is independent from the MDO system.
