Umbilical cables are 30 per cent smaller than alternatives
Tyco Electronics is launching an ROV product line of heavy lift umbilical cables, neutrally buoyant tether cables and heavy tether cables for all lifting applications in offshore and marine environments. The compact cables all benefit from reduced weight and diameter, providing longer length on current handling equipment.
All three cable types feature high voltage ratings, high-temperature, reduced-diameter power conductors with flexible conductors, screened twisted-pairs for instrumentation, and co-axial or databus conductors for data and video. Furthermore, the cables feature MM or SM Fibre In Steel Tube (FIST) and grounding via copper tapes.
Tyco Electronics says its heavy lift umbilical cables are typically 30 per cent smaller than cables from its competition, allowing longer excursion without the heavy investment cost of new winching equipment. Umbilical cables feature a bespoke cable design, two- or three-layer, torque-balanced steel wire armour packages, typical depth ratings to 4000m and EMC immunity via tin-plated copper braid.
Neutrally buoyant tether cables benefit from a neutrally buoyant TPR sheath and flexible yet mechanically resistant sheath. The cables are available in bespoke designs and aramid yarn armour packages. Excursion lengths are up to 1000m.
Heavy tether cables feature minimum-diameter, maximum-length tethers with a flexible, mechanically resistant TPR sheath. The cables are available in bespoke designs and aramid yarn armour packages.
