Overview - IEC TR 60092-370:2009 (Telecommunication & RF Cables for Ships)
IEC TR 60092-370:2009 provides practical guidance for the selection and installation of telecommunication, data transfer and radio‑frequency (RF) cables in shipboard and offshore unit electrical systems. It covers analogue and digital signal and control networks and includes guidance for high‑frequency cables (reported in the document as signals above 10^5 Hz). The report focuses on marine‑grade cable choice and installation practices, excluding fibre‑optic, subsea/umbilical cables and cables intended for direct connection to low‑impedance supplies or for limited circuit integrity (fire‑resistant) applications.
Key topics and technical requirements
- Cable selection principles - Recommend cables built to the IEC 60092 series and acceptable land-based standards when suitably adapted for marine use.
- Conductor requirements - Circular copper conductors (plain or metal‑coated) or copper‑covered steel; stranded conductors preferred; construction per IEC 60228.
- Insulation considerations - Use materials listed in IEC 60092‑351, IEC 60096‑0‑1 or IEC 61156‑5‑1. Insulation thickness, uniformity and rated operating temperature must suit the marine ambient.
- Cable elements and identification - Durable core/pair identification, control of lay length to manage crosstalk and handling.
- Screening and shielding - Guidance on metallic laminated tapes, drain wires, copper braid and combined shields; attention to galvanic protection in saliferous environments.
- Mechanical and installation factors - Bend radius, tensile and compressive stresses, risk of mechanical damage and continuous flexing considerations.
- Electrical performance - Electromagnetic interference (EMI) mitigation, termination and joint practices, current and voltage rating guidance for data/telecom and RF cables.
- Testing, marking and documentation - Selection of appropriate tests, marking requirements and guidance for performance assessment (including fire behaviour considerations are addressed, but fire‑resistant cable selection is outside scope).
Practical applications and users
- Shipbuilders and naval architects specifying onboard communication and RF cabling systems.
- Marine electrical engineers selecting cables for bridge systems, navigation, communications, automation and radio equipment.
- Offshore platform designers and maintenance teams responsible for reliable data and control cabling in harsh marine environments.
- Procurement and classification societies assessing conformity of telecommunication/data cable installations on ships and offshore units.
