Orange Marine (formerly France Télécom Marine) is a wholly owned subsidiary of Orange S.A. It is a major actor in the laying of new submarine communications cables and the maintenance of existing cables across the world's oceans. The company is active in all areas of these activities, including the study (survey) and the shore ends. Orange Marine took control of Elettra (previously owned by Telecom Italia) on October 1, 2010, and now operates 6 cable ships - i.e. 15% of the world fleet. Orange Marine and Elettra CEO is Raynald Leconte, Chief Engineer of Mines.

Installation and maintenance activities[edit]

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 of submarine cable in all oceans, 15,000 of which were buried with its ploughs. In total, cable ships have carried out nearly 300 repairs, some of which at a depth of 5000 metres over the last ten years.

Orange Marine has recently 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.

Cable ships fleet[edit]

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 6 [cable ship]s 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 Mediterranean sea, Black sea and 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 Rene 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.le Certamen
  • C/S Teliri operates laying operations, mainly around the Mediterranean Basin.

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.

Key figures[edit]

  • more than 130 000 kilometres of submarine cables laid in all the oceans, of which 15 000 buried by the ploughs
  • about 150 repair operations between 2006 and 2010
  • 4 operation zones: ACMA (Atlantic and Northern Europe), MECMA (Mediterranean, Black Sea, Red Sea), Southern Hemisphere (West, South and East Africa) and the Indian Ocean
  • cable ship Chamarel, alias Vercors, laid in the past 40 years 120 000 km of submarine cables on her own
