Steeltube umbilicals

Steeltube umbilicals typically provide hydraulic fluid for control, various chemical fluids for injection into the flowline, electrical power, and electrical - or fiber - optic signal transmission.

Why steeltube umbilicals?
OneSubsea’s steeltube umbilical designs provide a reliable and durable way of connecting onshore or offshore hosts with subsea facilities.
Core benefits

Application

  • Absorbs the impact energy from dropped objects efficiently through elastic deformation
  • Accepts very high installation crush load from tensioner
  • Components are effectively protected through all umbilical manufacturing processes and spooling
  •  

Features

  • Characterized by long lay (pitch) length of the components and all components supported within channel elements
  • The design offers high cross section lay - out flexibility and improved fatigue capacity
  • Predictable opening of the umbilical package and repair of components should damage occur
  •
