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.

OVERVIEW

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

Provide protection

Our steeltube umbilicals provide individual support for each of the internal elements, hold high installation tensioner loads, and protect against sharp edges.

Risk-free installation

Most failures to umbilicals occur during installation. OneSubsea offers increased robustness – reducing risk of damage during installation and operation.

flexible design

Our steeltube umbilicals have no armor, so can be bent in any direction eliminating “bird caging”.

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
