Introduction to Marine Shipboard Cables
Marine vessels and offshore platforms operate in one of the most demanding environments for electrical systems—constant vibration, saltwater corrosion, extreme temperature fluctuations, and strict fire safety requirements. Marine shipboard cables designed to IEC 60092 standards are the specialized cables engineered to ensure reliable power, control, and communication in these critical applications.
From cargo vessels and cruise ships to FPSO units and drilling rigs, every electrical circuit onboard must comply with classification society rules and international maritime standards. TEBAOFLEX manufactures a comprehensive range of IEC 60092 marine cables including power, control, instrumentation, and fire-resistant types, approved by major classification societies.
What Are Marine Shipboard Cables?
Marine shipboard cables are power and control cables specifically designed for fixed installation aboard ships and offshore units. They are governed by IEC 60092, the international standard series for electrical installations in ships. Key cable types include:
- Power cables (IEC 60092-353): For power distribution at voltages up to 0.6/1 kV and beyond, with EPR or XLPE insulation and heavy-duty rubber or LSZH sheaths
- Control cables (IEC 60092-376): For control and monitoring circuits, typically 0.15 kV rated with multi-core configurations
- Instrumentation cables: For sensors and measurement systems, with individual pair shielding and overall screen for EMC protection
- Fire-resistant cables (IEC 60331): For emergency circuits (lighting, alarms, fire pumps) that must maintain function during fire
The IEC 60092 standard series covers material requirements, construction, test methods, and installation guidelines specific to the marine environment. Explore our marine cable product range for detailed specifications.
IEC 60092 Construction Requirements
Marine shipboard cables must meet specific construction criteria mandated by IEC 60092:
Conductors
Tinned copper conductors are standard for marine cables, providing corrosion resistance in salt-laden atmospheres. IEC 60092-350 specifies Class 2 stranded conductors for power cables and Class 5 flexible conductors for control and instrumentation cables.
Insulation
EPR (ethylene propylene rubber) insulation per IEC 60092-353 is the preferred material for marine power cables, rated for 90°C continuous operation. XLPE (cross-linked polyethylene) is also permitted. For fire-resistant cables, mica tape is applied over the conductor before insulation.
Inner and Outer Sheath
Marine cables use dual-sheath construction: an inner sheath (bedding) of rubber compound and an outer sheath of CSP (chlorosulfonated polyethylene), PCP (neoprene), or LSZH (low smoke zero halogen) material. The outer sheath must be oil-resistant, flame-retardant (IEC 60332-3), and resistant to seawater.
Armor
For mechanical protection during installation and service, marine cables may include steel wire braid (SWB) or steel tape armor (STA). For single-core cables, non-magnetic armor (aluminum) is used to prevent eddy current losses.

Classification Society Approvals
Marine cables must be type-approved by classification societies recognized by the International Maritime Organization (IMO). TEBAOFLEX marine shipboard cables carry approvals from:
- DNV (Det Norske Veritas) — Norwegian classification society, widely used for offshore installations
- Lloyd’s Register (LR) — UK-based, standard for global shipping
- ABS (American Bureau of Shipping) — US classification society for vessels and offshore units
- Bureau Veritas (BV) — French classification society
- RINA (Italian Register of Shipping) — Italian classification society
- CCS (China Classification Society) — for Chinese-built vessels

Marine Cable Applications
Marine shipboard cables serve critical functions across vessel and offshore platform systems:
Power Distribution
Main power cables carry generator output to switchboards and distribution panels throughout the vessel. Medium-voltage cables (up to 8.7/15 kV) connect high-power propulsion systems and thrusters. See offshore application cases.
Control and Automation
Ship automation systems, engine room monitoring, and ballast control rely on multi-core control cables with individual screening for electromagnetic compatibility in dense cable routing environments.
Emergency and Safety Systems
Fire alarm systems, emergency lighting, fire pump power supplies, and shutdown systems require IEC 60331 fire-resistant cables that maintain circuit integrity for 90+ minutes during fire conditions at temperatures up to 950°C.
Offshore Oil and Gas
FPSO units, drilling platforms, and production vessels require marine cables with oil-resistant CSP or PCP sheaths, additionally certified for hazardous area use per IEC 60079.
Selection Guide for Marine Cables
- Identify voltage and application: Power (IEC 60092-353) or control (IEC 60092-376), and rated voltage level
- Select insulation type: EPR for standard marine power, mica+EPR for fire-resistant circuits
- Choose sheath material: CSP for oil resistance, LSZH for smoke-limited areas, PCP for general marine use
- Verify flame rating: IEC 60332-3 Cat. A is mandatory; IEC 60331 for emergency circuits
- Check classification approval: Confirm DNV, LR, ABS, or BV type approval per vessel flag state — view our certifications
- Evaluate EMC needs: Use individually screened pairs for instrumentation and overall screened cables for control
- Specify armor if required: SWB for mechanical protection in exposed areas; non-magnetic for single-core AC
- Request consultation: For complex vessel projects, contact TEBAOFLEX for engineering support
