StandardsInternational : Manufacturer specification
Towed and bottom laid seismic acquisition systems require a wide range of cables. Nexans manufacture and terminate cables such as gunumbilicals, sensor cables, riser cables and lead-in cables for sub-sea seismic operation down to 2000m water depth.
Riser cables and lead-in cables correspondingly for bottom laid and towed seismic systems typically comprises high performance signal quads, optical fibres and power conductors.
Each cable section has a torque balanced steel wire armouring. The armouring is Galfan coated (Zn/Al alloy), thus giving an improved corrosion protection.
The riser cables can be operated down to 2000m water depths.

Docs and info
Terminations can be provided for all Nexans seismic cables.
Terminations for riser/lead-ins typically comprise of a mechanical cone termination, a jacket to bulkhead sealing and a electrical/optical penetrator. These terminations are qualified for 2000m water depths.
