Oil, Gas & Marine Cable Solutions
Oil, Gas & Marine Cable Solutions for Offshore, Petrochemical and Vessel Applications
TEBAOFLEX supports cable selection for offshore platforms, FPSOs, drilling systems, refineries, petrochemical plants and marine vessels. Construction is reviewed against the circuit function, installation route, fire-performance requirement and exposure to oil, drilling fluids, chemicals, moisture and marine conditions.
Selection framework
Four Inputs That Define the Cable Construction
Oil, gas and marine cable selection begins with the installation context rather than a product name. These four inputs establish the first engineering boundary before voltage, conductor size, materials and approvals are confirmed.
Route and Service
Fixed tray, enclosed area, exposed deck, flexible connection, portable equipment or tubing-encapsulated route.
Actual Exposure
Oil, drilling mud, saltwater, humidity, UV, chemicals, temperature and mechanical loading.
Circuit Function
General power, fire-critical power, control, instrumentation, communication or integrated services.
The application defines the environment. The circuit function defines the cable construction.
Operating environments
Cable Solutions by Oil, Gas and Marine Operating Environment
Use the operating environment to narrow the route, hazard and material requirements. The same facility may require several cable constructions because normal power, instrumentation and emergency circuits have different duties.

Offshore facilitiesPower Safety Signals Equipment
Cable Solutions for Offshore Oil & Gas Facilities
Fixed platforms, FPSOs, jack-up rigs, semi-submersible units and production systems combine process power, safety circuits, monitoring and exposed deck routes. A project may therefore need normal-operation cable families together with fire-resistant, screened or mechanically protected constructions.
General Distribution
Switchgear, motors, pumps, compressors, HVAC, utilities and lighting. RFOU and other offshore power cable constructions are reviewed against the confirmed route and project standard.
Emergency Circuits
Fire pumps, emergency lighting, generators, ESD and alarm circuits may require verified circuit integrity during fire, making BFOU-type construction relevant where specified.
Control & Instrumentation
Process monitoring, sensors and control loops require core identification, screening and EMC performance matched to signal type and installation geometry.
Drilling Systems
Drill-floor, mud-handling and portable equipment can add oil, mud, bending and mechanical loads that must be separated from fixed-installation assumptions.
FPSO application
Cable Systems for FPSO Power, Control and Safety Circuits
An FPSO combines marine movement, production modules, storage and offloading functions. Cable selection must coordinate the electrical duty with route, fire zone, deck exposure and project documentation.
Power Distribution
Feeders for switchboards, motors, pumps, HVAC, utilities and production equipment.
Process Control
Multicore and screened cables for sensors, control systems, instrumentation and monitoring.
Emergency Systems
Fire pump, emergency lighting, alarm, shutdown and essential circuits requiring project-defined fire performance.
Onshore process plants
Cable Solutions for Refineries and Petrochemical Plants
Refineries, gas-processing plants, pipeline stations and tank farms place the emphasis on hydrocarbons, chemicals, temperature, flame propagation, fixed industrial routing and signal integrity. Offshore claims should not automatically be transferred to an onshore product without checking its own specification.
- Process power: motors, pumps, compressors and auxiliaries.
- Control and instrumentation: PLC/DCS signals, sensors and transducers with suitable screening.
- Ignition and flare systems: high-temperature and high-voltage cable selected for the confirmed ignition circuit.
- Emergency systems: shutdown, alarm and fire-safety circuits with documented fire-performance requirements.
Shipboard systems
Marine Cable Solutions for Ships and Offshore Vessels
Commercial vessels, offshore support vessels and workboats require coordinated cable systems for the main switchboard, engine room, accommodation areas, deck machinery and emergency services. Fixed shipboard circuits and frequently flexing deck connections must be specified separately.
- Shipboard power: distribution to motors, HVAC, lighting and vessel services.
- Emergency power: essential and safety circuits where verified fire resistance is required.
- Deck machinery: winches, mooring equipment and exposed routes with mechanical and weather loads.
- Control and instrumentation: monitored systems requiring clear core organization and signal protection.

Standards and approvals
Offshore & Marine Cable Standards and Project Requirements
Standard references define different aspects of construction, selection or fire testing. Applicability must be confirmed for the specific cable, voltage, installation and destination project; a standard mentioned here does not mean every TEBAOFLEX product carries every approval.

|---|---|---|
| IEC 60092-350 | General construction and test methods for shipboard and offshore power, control and instrumentation cables for fixed electrical systems within its scope. | Cable type, voltage, route and applicable edition. |
| IEC 61892-4 | Cable selection for fixed electrical systems on mobile and fixed offshore units within its defined scope. | Unit type, fixed-system status and project design basis. |
| NEK TS 606 | Offshore cable requirements where the project specification calls for this technical specification. | Project-specified edition, cable designation and documentation. |
| IEC 60331 series | Fire-test methods for circuit integrity under defined conditions and cable scope. | Required part, cable size, test condition and acceptance evidence. |
| IEC 60332 series | Flame-propagation test methods for single cables or bunched cables, depending on the specified part. | Exact part/category and product test report. |
| Project / class requirement | DNV, ABS, LR, BV or other class and owner requirements when explicitly specified. | Selected product approval scope and destination acceptance. |
Applicable standards, approvals and certification scope must be confirmed for the selected cable type and destination project.

Oil, Gas & Marine Cable FAQ
Short answers for project buyers and engineers. Product suitability still depends on the confirmed datasheet, route, circuit duty and required standard.
What cables are used on offshore oil and gas platforms?
Typical systems include fixed power, fire-resistant power, control and instrumentation cables. RFOU, BFOU, marine power and screened signal families may be considered, but the final type depends on circuit function, voltage, installation and project requirements.
What is the difference between BFOU and RFOU cables?
RFOU is commonly considered for general offshore power distribution, while BFOU adds a fire-resistant construction for applicable safety circuits. Confirm the exact product specification and fire-test requirement rather than selecting by name alone.
Which cable is suitable for FPSO power distribution?
General feeders may start with an offshore or marine power-cable family such as RFOU, while emergency circuits may require BFOU or another fire-resistant construction. Voltage, ampacity, route, fire zone and class/project rules determine the final selection.
When is a fire-resistant offshore cable required?
It is relevant when the project requires a circuit to maintain integrity during a defined fire test, such as for emergency power, fire pumps, alarms or shutdown functions. The specified standard, duration and test scope must be confirmed.
What cable is suitable for oil, drilling mud and marine exposure?
Select a sheath and construction whose documented test scope matches the actual fluid, temperature and exposure. No single material claim should be applied to every oil, mud, chemical and seawater condition.
What standards apply to offshore and marine cables?
Projects may reference IEC 60092, IEC 61892, NEK TS 606, IEC 60331, IEC 60332 and owner or class requirements. Applicability depends on cable type, circuit, installation and the edition specified by the project.
What information is required for an oil and gas cable quotation?
Provide facility, circuit function, voltage, cores and conductor size, installation, environmental exposure, fire requirement, standard, approval needs, length, quantity, destination and any datasheet or drawing.
Can TEBAOFLEX customize offshore power, control and instrumentation cables?
Project-specific core configuration, screening, protection, sheath, fire-performance construction, integrated elements and marking can be reviewed when the technical requirement and applicable standard are supplied.
