Role and Operations
Ile d'Aix is a cable repair vessel operated by ASN Marine, the marine arm of Alcatel Submarine Networks — one of the industry's principal cable manufacturers and marine contractors.
Where installation ships lay entirely new cable systems across ocean floors, repair vessels like Ile d'Aix are tasked with maintaining cables already in service: locating faults, recovering damaged sections from the seabed, splicing in replacement lengths, and reburying cable in shallow-water areas where it is most vulnerable to anchors and fishing gear.
Equipment and Capability
According to the ICPC cable ship registry, Ile d'Aix carries plough and/or ROV capability. A plough is a steel sled towed along the seabed that buries cable into the sediment as it is laid or relaid, protecting it from external aggression. An ROV — remotely operated vehicle — is an unmanned submersible used to inspect, cut, and recover cable at depths beyond the reach of divers.
Together, these tools allow a repair team to handle faults across a wide range of water depths and seabed conditions. The ship's cable tanks hold up to 4,000 tonnes of cable, providing the capacity to carry substantial replacement lengths on a single mobilisation.
Base Port and Fleet Context
Ile d'Aix is registered at Calais, on France's English Channel coast — a location that places the vessel within reach of the dense concentration of submarine cables crossing the North Sea and the Channel, among the most heavily trafficked cable corridors in the world.
As part of the ASN Marine fleet, the ship sits within a global contracting organisation that covers both the manufacture of cable systems and their long-term maintenance under service agreements.
