Subsea Electro-Pneumatic Umbilical
Custom Subsea Electro-Pneumatic (E-P) Umbilicals
As a premier custom subsea umbilical manufacturer, our Subsea Electro-Pneumatic Umbilicals are engineered to be the integrated lifelines for your subsea production and control systems. Designed to connect surface facilities to subsea equipment across the most challenging deep-water environments, they reliably deliver power, control signals, and essential fluids in a single, robust, and custom-engineered cable.
Integrated Core Functions
These umbilicals combine multiple critical functions into one optimized, ruggedized solution, eliminating interface complexity on the seabed:
Power Transmission: Provides reliable electrical power to subsea control modules (SCMs), sensors, and instrumentation.
Control & Communication: Facilitates command via electrical signals and/or pneumatic impulses, while integrated fiber optics enable high-speed data telemetry for real-time monitoring.
Hydraulic Power Supply: Delivers high-pressure hydraulic fluid to operate subsea valves and actuators.
Chemical Injection: Dedicated tubes (stainless steel or thermoplastic) allow for the direct injection of inhibitors, methanol, or other flow assurance chemicals.
Engineered for Reliability & Performance in Harsh Environments
Built to withstand extreme pressures, temperatures, and dynamic stresses, our umbilicals are defined by superior materials and construction:
Custom-Engineered Design: Tailored configurations of electrical cables, hydraulic/pneumatic tubes, and optical fibers to meet exact project specifications.
High-Strength Armor: Layered steel wire armor (SWA) provides superior tensile strength and crush resistance for both dynamic and static applications.
Durable Sheathing: Advanced polyurethane, XLPE or HDPE outer sheaths ensure long-term protection against corrosion, abrasion, and marine environmental factors.
Applications
Subsea Production Control Systems
Manifolds & Tree Controls
Subsea Processing Units (e.g., Pumps, Compressors)
