Overview

IEC 60092-353:2024 (Edition 5.0) is the International Electrotechnical Commission standard for shipboard and offshore power cables with extruded solid insulation and rated voltages of 0,6/1 (1,2) kV and 1,8/3 (3,6) kV intended for fixed installations. It covers non‑radial field power cables used in marine and offshore environments, including cables designed to maintain circuit integrity during a fire. The standard harmonizes constructional requirements and test methods with IEC 60092-350 and references insulating/sheathing material requirements in IEC 60092-360.

Key Topics

• Scope and applicability: Defines cable types for shipboard/offshore fixed installations at 1 kV and 3 kV classes, including fire‑resistant variants.
• Constructional requirements: Specifies conductor, insulation, cabling, inner coverings, screens, sheathing and armour options (armoured and unarmoured constructions).
• Insulation and materials: Aligns material selection and thickness requirements with IEC 60092-360; covers extruded solid insulation types.
• Marking and identification: Requirements for voltage, origin and core identification to ensure traceability and safe installation.
• Special applications: New subclause 5.10 addresses construction for special cases such as installation in or between areas with explosive atmospheres.
• Testing and conformity: Test methods and requirements are aligned with IEC 60092-350; Table 9 (new) adds tests for installation between explosive/non‑explosive areas. The edition removes IEC 60331-21 as a test requirement and deletes the former Annex A.
• Safety and reliability objectives: Standardizes manufacturing and testing criteria to ensure cables provide the required safety and performance when installed per IEC 60092-352 or IEC 61892-4.

Applications

Who uses IEC 60092-353 and where it applies:

• Shipbuilders and naval architects specifying power distribution cables on commercial and naval vessels.
• Offshore platform designers and FPSO operators for fixed power cabling systems.
• Cable manufacturers developing marine-grade, fire-resistant, halogen-free or low‑smoke power cables at 1 kV and 3 kV ratings.
• Classification societies, marine electrical contractors and inspectors checking compliance with installation and testing requirements.
• Typical uses include main and secondary power feeders, distribution circuits, and installations requiring circuit integrity under fire or in hazardous/explosive atmospheres.

Related standards

• IEC 60092-350 - General construction and test methods for shipboard/offshore cables
• IEC 60092-360 - Insulating and sheathing materials for shipboard/offshore cables
• IEC 60092-352 / IEC 61892-4 - Installation requirements for shipboard and offshore electrical systems
• Relevant fire and explosive atmosphere standards cited in normative references

IEC 60092-353:2024 provides the technical framework for designing, manufacturing and testing marine power cables (1 kV and 3 kV) to meet safety, reliability and installation requirements in demanding shipboard and offshore environments.

For cross sections of 185 mm² and above, the insulation thickness is suitable for 3 kV. If in this case a voltage
rating of 3 kV is designated to the cable, this cable should be tested as a 3 kV cable.
a
These values of the insulation thickness correspond approximately to the formula:
mm
t = 0,1 S + 0,9
b
All these values may be reduced by 0,1 mm if the rubber wall is covered by an extruded skin of polyamide
or equivalent material.
c
These values of the insulation thickness correspond approximately to the formula:
