Oil and Gas Production

Cables that power, control, and connect offshore production systems in harsh environments. 

Where safe control depends on the cable

Offshore drilling and production systems run under high pressure, mechanical load, and constant motion. Cables may be routed through topside cableways, down risers, or into subsea umbilicals and control pods. They must tolerate tension, bending, and repeated handling while delivering power and a clean signal to valves, sensors, and control systems. A cable failure can interrupt production, slow drilling, or compromise critical safety systems such as blowout preventer controls.

How we engineer cables for offshore and subsea production

Rochester Cable has proven experience supplying cables for offshore drilling, subsea control, and production support systems. Our designs focus on mechanical strength, insulation performance, and signal integrity under pressure, fluid exposure, and vibration. We work with system integrators and offshore operators to develop cable constructions for MUX control lines, production umbilicals, and related subsea assemblies.

Key design priorities

Mechanical robustness and handling performance
Armored and strength-member designs that handle installation loads, dynamic movement, and routing through topside and subsea equipment.

Power and control integrity
Conductor sizing, insulation systems, and screening that support high-voltage power, control, and communication in a single cable, where required.

Signal and data paths
Twisted pairs, screened pairs, coaxial, and optical fibers for control, status, and monitoring signals, designed to minimize noise and attenuation.

Integration into larger systems
Cable configurations tailored for use as components in multiplexer (MUX) control cables and production umbilical component (PUC) packages.

Offshore Drilling and Exploration

Offshore drilling and exploration require robust cable systems to support rig operations, downhole tools, and topside control systems. Cables must handle installation and operation in harsh marine conditions while keeping systems online.

What our cables deliver for drilling and exploration:

  • Constructions suited for use in and around marine drilling equipment and support systems
  • Power and control paths for equipment that supports the drilling operation
  • Jacket and armor options chosen for offshore environments and handling on rigs and vessels

Subsea Control Systems

Subsea control systems operate valves, actuators, and safety devices on the seafloor. Cables within these systems must carry power and control signals reliably between topside control equipment and subsea control modules.

What our cables deliver for subsea control systems:

  • Electro and electro-optical designs suitable as components of subsea control umbilicals and MUX control lines
  • Conductor and fiber configurations sized for multiple control and feedback channels
  • Mechanical designs that match the requirements of integrators who build complete umbilical and control packages

Drilling and Blowout Preventer Operations

Blowout preventer (BOP) systems and related drilling controls rely on fast and dependable communication between the rig and subsea BOP stack. Cabling is a vital link in multiplexer-based control architectures.

What our cables deliver for drilling and BOP operations:

  • Cable constructions suitable for use in MUX control systems that link the rig to subsea BOP control pods
  • Power and signal paths designed to support real-time control and status monitoring
  • Mechanical and insulation systems designed for routing along risers and through handling equipment

Production Umbilical Components

Production umbilical components (PUC) are individual cables and elements that are built into large subsea production umbilicals. These components carry power, control, and communication between topside production facilities and subsea wells and manifolds.

What our cables deliver as PUC components:

  • Electro and electro-optical cable designs configured for use as elements within larger production umbilicals
  • Options for steel, synthetic, or armor-free packages depending on the umbilical design
  • Screened and non-screened configurations tailored to control, power, and communication requirements

Subsea Monitoring and Instrumentation

Subsea monitoring and instrumentation systems track pressure, flow, temperature, and equipment condition at wells, manifolds, and along pipelines. Their cables must support reliable data transmission and power delivery to distributed sensors.

What our cables deliver for subsea monitoring:

  • Configurations that support sensor power, control lines, and data return in a single cable where appropriate
  • Designs suitable for integration into umbilicals, jumpers, or dedicated monitoring cables
  • Mechanical protection and jacketing selected for long-term subsea service
