The development of telecommunications and in particular the constantly increasing demand of digital services make the submarine telecommunication cables very strategic and the users of these services very sensitive to interruptions or degraded quality. Then, the main cause of faults on submarine telecommunication cables is trawler or anchor damage. Therefore, once the route has been finalized, only a good quality of burial can reduce the risks linked to these external aggressions. The tools used to-day by France Telecom for burial are: a standard sea-plough, with a share, towed by the cableship simultaneously to the laying operation; ROVs (SCARAB) to post-lay bury cables by jetting, repair buried cables and rebury the cable after repair. |
