Orange Marine

Orange Marine lays new submarine cables and repairs broken links without any interruption of traffic. Orange Marine and Elettra fleets perform an average of 40 operations a year.

Orange Marine has laid more than 130,000 kilometres (81,000 mi) of submarine cable in all oceans, 15,000 km (9,300 mi) of which were buried with its ploughs. From 2001 through 2011, cable ships carried out nearly 300 repairs, some of which were at a depth of 5,000 metres (16,000 ft).

Orange Marine has completed the laying and maintenance of cables in West Africa in Senegal, Cameroon, Benin, Angola, Nigeria and South Africa, as well as in East Africa, Reunion Island, Madagascar and Mauritius, Asia and Indonesia. The company also laid a new cable in the Caribbean sea, linking U.S. Virgin Islands, the Dominican Republic and Jamaica.

The fleet covers all of the world's oceans, divided into four regions of operation: ACMA (Atlantic and Northern Europe), MECMA with Elettra (Mediterranean, Black Sea, Red Sea), Southern Hemisphere (West, South and East Africa) and the Indian Ocean. Submarine cables laid in the same area are covered by a maintenance agreement.

Orange Marine and Elettra own a fleet of six cable ships and a complete range of submarine engines, shipping from its marine bases or foreign harbours:

• Cable ship (C/S) Raymond Croze, based in la Seyne-sur-Mer at the MMB (Mediterranean Marine Base), performs the repairs on cables in the Mediterranean, the Black Sea, and the Red Sea.
• C/S Leon Thevenin, based in Brest at the AMB (Atlantic Marine Base), repairs the cables in the Atlantic zone and in Northern Europe.
• C/S Chamarel, based in Cape Town (South Africa), operates in the Southern Hemisphere.
• C/S René Descartes is dedicated to the installation of submarine cables on a worldwide range.
• C/S Certamen works with the Raymond Croze on cable maintenance in the Mediterranean, Black and Red Seas.
• C/S Teliri operates laying operations, mainly around the Mediterranean Basin.
• C/S Antonio Meucci conducts submarine systems inspections, ROV operations and maintenance of telecommunications cables.
• C/S Pierre de Fermat maintains submarine cables in the Atlantic and Northern Europe zone.

Elettra operates two cable ships, the Certamen and the Teliri, under the Italian flag, and owns a cable depot in Catania.

In order to protect, watch and repair intercontinental damaged links, Orange Marine, through its subsidiary SIMEC, designs, manufactures and operates submarine vehicles (ROV and ploughs) used to carry out assignments:

• The Hector ROV (Remotely Operated Vehicle), which is remotely controlled from the ship via its umbilical cable, can lift the cable, hold it and cut it using articulated arms.
• Elodie, the plough, is used to bury the cable at significant depths.

• more than 130,000 kilometres (81,000 mi) of submarine cables laid in oceans, of which 15,000 km (9,300 mi) have been buried by Orange Marine ploughs
• about 150 repair operations between 2006 and 2010
• four operation zones: ACMA (Atlantic and Northern Europe), MECMA (Mediterranean, Black Sea, Red Sea), Southern Hemisphere (West, South and East Africa) and the Indian Ocean
• in the past 40 years cable ship Chamarel, alias Vercors, laid 120,000 km (75,000 mi) of submarine cables
