ROV cable, umbilicals & tether designs showcased by Nexans at Oceanology 2012 Show
Nexans, a worldwide expert in the cable industry, is at Oceanology 2012 to promote its wide range of cable solutions developed to meet the specific needs of workclass ROV manufacturers and operators.
Nexans’ specialized ROV cable manufacturing facility in Norway can produce steel armoured umbilicals for vehicles commonly used for trenching, ploughing, maintenance and drill support applications. The cables are typically designed with a two or three layer torque balanced armouring and 3 phase power supply, instrumentation and fibre optics. The typical depth rating is 2000 to 4000 metres.
ROV Umbilicals – for depths down to 7,000 metres
Deep water umbilicals are designed for dynamic deep water applications rated down to 7000 metres and the conductors and fibre optics are armoured with special aramid yarns providing high strength. They are used typically in deep water mining.
The umbilical cables are easy to maintain in salt water environments through simple cleaning, hosing and greasing and offer the versatility to operate with complete reliability in harsh environments.
Nexans is a well established supplier of cables for the global ROV market, with the capability to draw on a wide range of standard electrical and fibre elements that, combined with customized armouring packages, create highly dynamic, torque balanced, compact solutions that deliver the essential reliability and robustness required for subsea applications.
ROV tethers – designed for durability
Nexans flexible and durable TMS (Tether Management System) cables are designed for use with ROVs deployed in tethered applications or directly from the surface for smaller ROVs. They are strong, lightweight, neutral and positively buoyant and are suitable for use in a variety of underwater applications.
