IEEE 45: Standard for Shipboard Electrical Power Systems
Standard for marine electrical systems including inspection requirements.
IEEE maintains IEEE 45 as a published consensus standard used across the NDT industry.
IEEE 45 becomes enforceable when invoked by a contract, regulatory citation, or another standard that references it as the controlling document.
IEEE 45 is invoked when the scope of work matches its title — standard for shipboard electrical power systems — and when the contract or regulatory regime cites it as the controlling document.

- Marine
- Offshore
- Personnel qualification: examinations under IEEE 45 must be performed by inspectors qualified and certified to a recognised scheme (typically ASNT SNT-TC-1A, CP-189, or ISO 9712 depending on jurisdiction), with documented training hours, vision tests, and a controlling written practice.
- Written procedure: every examination requires a written, controlled procedure that names the method, equipment, calibration steps, scanning pattern, and acceptance criteria — and is qualified before first use.
- Eddy-current setup: probe selection, frequency, gain, and reference-standard calibration must be documented and verified against a reference standard with known artificial flaws prior to inspection.
- Acceptance criteria: indications are evaluated against the standard's tabulated limits (length, depth, alignment, frequency); any indication exceeding the criteria is recorded, dispositioned, and either repaired or evaluated for fitness-for-service.
- Documentation: examination reports must include enough information for a third party to reproduce the inspection — equipment serial numbers, calibration records, inspector ID, sketches of indications, and the controlling procedure revision.
IEEE 45 is maintained on its publishing organisation's revision cycle. The version cited in any contract or written inspection program should be tracked so that revisions can be reviewed against the existing inspection plan and any clause changes worked into the next procedure update.
On a typical Marine job, IEEE 45 is reproduced inside the inspection company's written procedure, the procedure is qualified for the customer, and each examination report cites the procedure revision back to the controlling clause of the standard.
What does IEEE 45 cover?
IEEE 45 (Standard for Shipboard Electrical Power Systems) is published by IEEE. Standard for marine electrical systems including inspection requirements..
Is IEEE 45 mandatory or voluntary?
IEEE 45 is a consensus standard. It becomes mandatory when invoked by a contract, by another code that cites it (for example ASME Section V calling out an ASTM practice), or by a regulator that has adopted it into law in a specific jurisdiction.
Who is qualified to perform inspections under IEEE 45?
Inspections under IEEE 45 must be performed by personnel qualified and certified to a recognised NDT certification scheme — most commonly ASNT SNT-TC-1A or CP-189 in the United States, ISO 9712 in much of the rest of the world, and NAS 410 for aerospace work. The written practice that controls qualification must be in place before any examination is started.
Which other standards are commonly cited alongside IEEE 45?
IEEE 45 is most often cited together with the parent code that brings it into the contract — typically ASME Section V or VIII for U.S. pressure equipment, AWS D1.1 for structural welding, API 510/570/653 for in-service petroleum equipment, or the matching EN/ISO standard for European and international work.
