Shipboard zones, offshore modules and critical circuits
Marine & Offshore Cable Solutions for Vessels and Platforms
Map ship and platform areas to the required electrical function, fire strategy and environmental exposure. This solution separates normal power and instrumentation routes from emergency, earthing, deck and special offshore cable systems.
- Vessels and machinery spaces
- Deck and platform modules
- RFOU, BFOU, UX and SW4
Choose by system duty, not by name alone
Use this page to narrow the cable route before comparing a product model or submitting a specification.
Start with the equipment
Identify the machine, circuit function, route and the consequence of cable failure at that location.
Define the complete duty
State voltage or transmission needs together with movement, bending, load, fluids, temperature and installation exposure.
Confirm one construction
Review conductor or fibre elements, screens, reinforcement, sheath, termination, standards and documentation as one schedule.
Match the cable to the equipment and route
Cable selection changes by ship zone and service. Machinery spaces, open deck, accommodation, emergency routes and platform process modules do not share the same fire, mud, oil or mechanical requirements.
Machinery spaces
Power, control and instrumentation routes around motors, pumps, generators and switchboards with heat, oil and vibration exposure.
Open deck and exposed routes
Cable runs subject to salt, UV, water, abrasion and mechanical protection requirements.
Emergency and safety systems
Critical circuits where fire resistance and circuit integrity must be defined separately from normal flame-retardant routes.
Offshore process modules
Power, control and signal systems exposed to mud, hydrocarbons, compact tray space and project documentation requirements.
Accommodation and service zones
Low-smoke, halogen and flame requirements coordinated with vessel design and installation rules.
Umbilical and special routes
Combined power, control, data or video connections for underwater and special offshore equipment.
Define the conditions that control cable life
The cable family follows the vessel area, circuit criticality and named standard. Confirm fire performance, mud resistance and approvals at model level instead of treating all marine cables as interchangeable.
Separate cables that limit flame spread from constructions intended to maintain a circuit during a specified fire test.
Identify NEK 606 mud resistance, hydrocarbon contact, seawater, UV and washdown conditions by route.
Check tray fill, bend radius, armor, braid, glands, vibration and exposed deck protection.
State class, flag, yard, owner, IEC, NEK or BS requirements before product approval is discussed.
Compare suitable cable-family routes
Use vessel zone and circuit function to narrow the family, then confirm voltage, conductor size, screen, armor, fire behavior and applicable documentation.
RFOU power and instrumentation
Flame-retardant, low-smoke offshore routes for normal power, control and instrumentation duty where NEK 606 is specified.

Mica-based circuit integrity route for emergency and critical systems where the required fire test is named.

Dedicated earthing and grounding routes for offshore systems, checked for conductor size, sheath and project documentation.
View UX earth cableSW4 shipboard cables
Marine power and control routes following BS-style construction requirements where SW4 is specified by the project.

From operating data to an agreed cable schedule
The process keeps equipment, cable construction, interfaces and documentation aligned before production.
Share the operating duty
Provide the equipment, electrical or transmission services, movement, route and environment.
Review the cable route
Separate circuit functions and compare the constructions that fit the operating duty.
Confirm the technical schedule
Agree the construction, dimensions, interfaces, standards, inspection stages and document list.
Manufacture and inspect
Production, marking, packing and agreed inspection follow the confirmed order specification.
Frequently asked questions
Short answers to common questions before a project-specific cable review.
How are RFOU, BFOU, UX and SW4 routes compared?
They are construction families used for different vessel and offshore duties and should not be treated as interchangeable labels. Compare voltage, circuit function, fire strategy, armour, mud or oil exposure, installation zone and the exact project standard.
What is the difference between flame retardance and circuit integrity?
Flame retardance limits flame propagation under a stated test. Circuit integrity addresses continued operation for a specified circuit and test condition. Emergency routes must be defined by the project fire strategy.
When is armoured marine cable considered?
Armour may be selected where the installation needs mechanical protection or a specified construction system. Glands, bonding, corrosion exposure, bend limits and route geometry should be reviewed with the armour choice.
What should a marine cable enquiry include?
Send the vessel or module area, circuit function, voltage, conductor or pair count, armour and screen, fire and smoke requirements, mud, oil, salt and temperature exposure, route, length, quantity and documentation list.
