Oceanographic Research Vessel
R/V Marion Dufresne II
Named after the French explorer Marc-Joseph Marion du Fresne (1724-1772), R/V Marion Dufresne II is a multi-purpose, 120½-meter (395.3 ft.) long, research and supply vessel having two main missions: logistics for the French Austral Islands and oceanographic research. Specifically designed for very severe weather conditions, she benefits from an exceptional sea behavior – allowing full performance in rough seas.
The vessel is equipped with the full suite of geophysical facilities (including multi-beam bathymetry and imagery) and has unique capabilities for raising long sediment cores, up to 60 meters (her record core being 58 meters). With a capacity for 110 passengers, the Marion allows large scientific parties to embark on multidisciplinary programs.
The Marion Dufresne (IMO 9050814) is chartered by the TAAF (Territoire des Terres Australes et Antarctiques Françaises) on an annual basis from the shipping line CMA-CGM (Compagnie Maritime d'Affrètement - Compagnie Général Maritime). The ship was constructed by Ateliers et Chantiers du Havre (Normandy) and delivered on 12 May 1995; it is registered out of the port of Marseille, France, but its base of operations is the island of La Réunion.
[Ed. notes: The slightly smaller Marion Dufresne I (IMO 7208388) served the TAAF from 1973 to 1995 – replacing her predecessor, the Galliéni (1956-'73). After being decommissioned by the TAAF, she sailed under a Maltese flag as the Fres (possibly by painting over the other letters in 'Marion DuFRESne'?), in the capacity of a cable- and pipe-laying vessel. On 22 June 2004, she was taken to a marine salvage yard in Alang (India) to be broken up.]
The ship's power plant
The Marion Dufresne's smooth, vibration-free propulsion is provided by three 8,125-hp Cegelec electric motors – one forward (750 kW bow thruster) and two aft (AC synchronous electric propulsion motors: 2,650 kW ea) – manufactured by GEC Alsthom Moteurs* of Nancy, France (Meurthe-et-Moselle department of Lorraine). Power for the motors is generated by one 6-cylinder (6R32D) and two 8-cylinder (8R32D) diesel engines, manufactured by Wärtsilä (Helsinki, Finland).
[*Ed. notes: GEC Alsthom, whose history dates back to Compagnie Générale Électrique (1898), was renamed Cegelec Moteurs in 1989, then ALSTOM Moteurs in 1998 (dropping the 'h' from 'Alsthom'). The factory moved to Champigneulles (Meurthe-et-Moselle) in 2001-2002 and was renamed Converteam Motors in 2005, when it was acquired in a leveraged buyout by Barclays Private Equity. General Electric Co. of Fairfield, Connecticut (USA), agreed to purchase most of Converteam from Barclays in 2011.]
The Marion Dufresne's Eurocopter
Service in the Indian and Southern Oceans
While the TAAF also includes Terre Adélie in Antarctica and five islands near Madagascar, the Marion Dufresne is used to service the districts of Crozet, Kerguelen and the little islands of Amsterdam and St-Paul – delivering supplies, fuel, and personnel to the three permanently manned bases: Alfred-Faure, Port-aux-Français, and Martin de Viviès, respectively. (see route map)
Because some of the island ports are too shallow, or there are no ports at all, the Marion utilizes one of a series of helicopters to ferry provisions and personnel to and from the bases. These may include the Eurocopter AS365 Dauphin, Eurocopter Écureuil AS 350 B2, and Aérospatiale Alouette II or III. They are leased from HeliLagon on Réunion.
The Marion also carries a complement of several boats on board – which can be used for rescue missions, deployment of personnel and cargo to islands equipped with a dock or pontoon, access to undeveloped shoreline areas, repairing buoys, and a multitude of other purposes. The largest of these vessels is the container barge Gros Ventre ("Fat Belly"); others include a small utility boat, a semi-rigid rubber raft, and a zodiac.
From time to time, the Marion will play a role in saving mariners from the plights of seafaring. As recently as 15 December 2008, the ship was involved in rescuing Bernard Stamm, whose boat ran aground near the islands of Kerguelen during the Vendée Globe, a prestigious round-the-world single-handed yacht race. The monocoque "Cheminées Poujoulat" (named after its sponsor, a French manufacturer of residential chimneys) had embarked on the race from Sables-d'Olonne (La Vendée) in France on 9 November 2008, but ran into trouble during high winds in the South Ocean. Having sustained significant hull damage, it was hoisted on board the Marion and brought to La Réunion. (see photo gallery)
TAAF crews prepare to remove
Taking out the trash... hundreds of tons at a time
Where humans go, rubbish tends to follow – and the small scientific communities of the TAAF are no exception. Given their remote island settings, keeping the delicate ecosystems pristine can pose somewhat of a logistical challenge. After all, their connection to recycling and disposal facilities requires ferrying material by one tiny helicopter or a utility boat to the Marion Dufresne, which then hauls it all back to La Réunion for processing.
On 13 May 2009, Le Quotidien de la Réunion (daily newspaper) reported that the Marion Dufresne had just completed a massive reclamation project: removing nearly 500 tons of rubbish (fr. déchets) from three of the Scattered Islands (fr. Îles Éparses) in the Indian Ocean: Europa, Juan de Nova, and Les Îles Glorieuses (Glorioso Islands).
A later TAAF report puts the total of collected waste somewhat higher: 600 tons of ferrous metal, 14 tons of batteries, 2 tons of oil, 6½ tons of kerosene – much of it abandoned more than 50 years ago – including the remains of a rusted 1966 lighthouse on Juan de Nova. The report also added a fourth island to the reclamation effort, Tromelin. (see map)
The ambitious project, which lasted from 18 April to 13 May, 2009, also included a secondary mission: the implementation of a floating scientific platform containing 17 different oceanographic applications. According to the TAAF, "This exceptional operation, which was both a logistical and technical challenge, fully completed its objectives. It confirms the strategic and ecological importance of these islands, sentinels of world biodiversity."
Climactic conditions in the Southern Ocean
Traveling to the districts of Crozet and Kerguelen takes the ship through the Roaring Forties and the Furious Fifties, latitudes in the Southern Ocean where much greater wind speeds are able to build – compared to the same region of the Northern Hemisphere – due to the relative lack of any land masses below the 40th parallel. Wind speeds of 62 mph (100 kph) or greater occur during 100 days of the year at Crozet. As a result, it is not unusual for the ocean waves here to whip up as high as three-story buildings, dwarfing all but the largest of ships.
Eco-tourism on the rise
Like its Australian counterpart the Aurora Australis, the Marion carries its quota of scientists, logisticians, construction workers, and a smattering of doctors (the ship has a hospital with operating room). In recent years, the Marion has also played host to an increasing number of tourists (up to 14 per trip) who book passage for a period lasting about 28 days; the cost is generally between €5,500 and €8,600 pp, not including airfare or insurance. (See 2012 brochure or write to email@example.com for current information.)
The ship's cabin appointments are austere but comfortable, and several forms of recreation are available on board: badminton, chess, darts, foosball, swimming (in an extremely small pool), table tennis, a variety of exercise equipment, and volleyball. There is also a lively and convivial bar (known as the 'Forum'), a video/conference room, library, boutique, and laundry facilities.
While the ship's sleeping quarters may rank somewhere between a hostel and a 1-star hotel, the gastronomical fare on board is a different matter entirely. Meals served on the Marion Dufresne are considered to be of excellent quality, receiving accolades from both tourists and scientific personnel. The ship's well-appointed dining room can seat up to 58 at a time (meals are served in two shifts).
A 9,000-km (5,590 mi.) passage includes guided tours of Crozet, Kerguelen, and Amsterdam Islands – with ample opportunities to view the local wildlife. (Since 2007, Saint-Paul has been declared a nature preserve, and landing there is no longer permitted except by scientists.) Bring plenty of warm clothing, and at least a 4-week supply of dimenhydrinate (common brand: Dramamine) to combat seasickness!
World-wide research projects
Facing an increasing scientific demand, the French Ministry of Research decided in 1999 to reduce the ship time devoted to logistical operations to 120 days per year and allow the French Polar Institute (IPEV: Institut polaire français Paul-Émile Victor) to conduct research in all oceans, world-wide, 245 days a year.
Therefore, the ship is no longer confined to the Indian Ocean (for example, several months in 1999 were spent coring for paleo-climatic purposes in the North Atlantic). This paves the road for new approaches and the development of integrated, multidisciplinary programs, as recently evidenced by the MD120-ANTAUS expedition.
Accidents & mishaps
As the calamitous toppling of the Costa Concordia off the coast of Isola del Giglio (Tuscany) on 13 January 2012 will attest, navigation mishaps can occur with any ship – and the Marion Dufresne is no exception. Unlike the cruise ship, however, there were no lives lost when the TAAF's supply and research vessel struck a shoal off the shores of Île de la Possession (Crozet) on the night of 13-14 November 2012, causing significant damage to its hull.
The waters surrounding Crozet Archipelago, like those of many other remote islands in the Southern Ocean, are not particularly well-charted and therefore present certain navigation hazards for even the most experienced commanders – even during good weather. An investigation of the incident has not definitively established whether any operator error was involved in this case. A similar accident had occurred in 2005.
At the time, Marion Dufresne was conducting its re-supply mission called OP3 (opération portuaire #3), the busiest provisioning trip of the year when scientific personnel, food and other supplies are delivered for the austral summer season. OP4, scheduled for December 2012, as well as a number of planned scientific missions, were cancelled as a result of the mishap.
The France Télécom cable-laying ship Léon
Damage to the ship involved an 82-foot (25-meter) gash in its port bow, filling two watertight compartments, and disabling the bow thruster. With no injuries reported, 97 passengers (including 9 tourists) and 25 of the 48 crew members were evacuated by helicopter to the Alfred-Faure station on Crozet, until a contingent of engineers could be dispatched on the Coral Sea from Mauritius to inspect the ship's condition and effect temporary repairs. A skeleton crew of 23 remained on board to assure the ship's safety while moored in the Baie des Marins.
The cable-laying ship Léon Thévenin, belonging to France Télécom Marine, was sent from South Africa to repatriate all passengers who were not part of Alfred-Faure's summer personnel; it took that ship four days to reach Crozet.
Following a determination of seaworthiness and with a temporary navigation certificate issued by Bureau Veritas, the Marion Dufresne departed on 24 November – escorted by the Coral Sea – to the Elgin Brown & Hamer shipyard in Durban, South Africa, for repairs. (Its home port on La Réunion is not equipped for such operations.)
Total costs for restoring the vessel – plus passenger repatriation, tourist refunds, ship escort and related expenses – were reported at nearly €3 million. Repairs were completed and the ship left Durban to resume its normal duties on 30 January 2013, arriving first at La Réunion on 5 February; re-supply missions to the TAAF resumed in mid-March 2013.
