Prysmian Cable Deep Water Umbilicals Steel Tube Umbilicals Cable

Failure of an umbilical cable which links the platform to the wellhead can result in partial or total loss of production with resulting sever economic consequences. Steel tube umbilicals are designed to operate in the harshest of environments and ultra deep water applications, at depths of up to 3,000 meters.

Individual steel tube umbilicals can contain a number of functional components with the cable. These can include

• High pressure steel tubes
• High pressure hydraulic control hoses and tubes
• High pressure chemical and ethanol injection hoses
• Electrical power and control cables
• Fibre optic cables

The steel tubes are made from superior high-alloy stainless steel. Due to their nature they are not affected by the pressure, which allows for fast response times and prevention of permeation of fluids. In addition the stainless steel prevents corrosion due to high temperature and pressure fluids. In addition, long continuous lengths of steel tube umbilical cable are possible, using the latest laser welding technology and weld checking systems. This is particularly useful for the ultra deep water applications. Electric power cables and control cables are insulated and jacketed using the Prysmian Severex high performance compounds. Electric cable designs and performance can meet the most demanding applications.

The steel tubes are assembled on a high-capacity planetary stranding machine which is capable of handling steel tubes up to a diameter of 1.5 inches

The Prysmian’s plant in Vila Velha (Brazilian southeast coast), is equipped with enhanced manufacturing and storage capacity which includes high-load turntables [carousels] and bigger reels, which allows the loadout of very long continuous STU lengths. Situated on the coast, the Prysmian factory has a deep water berth, which allows for direct loading of heavy payloads directly onto installation vessels.
