Electrical & Automation Technical Case Study FAQ
What is an electrical and automation technical case study?
An electrical and automation technical case study documents a structured assessment of equipment condition, system configuration, inspection evidence, operational circumstances and relevant technical findings within an agreed scope.
What electrical systems can be assessed?
Depending on the assignment, assessments may cover marine electrical distribution, switchboards, control panels, automation systems, instrumentation, alarms, monitoring systems and associated electrical equipment.
Can PAMS inspect marine electrical systems?
Yes. Where access and the agreed scope permit, PAMS can provide independent technical inspection and assessment of accessible marine electrical equipment and associated systems.
Can PAMS investigate electrical or automation failures?
Yes. PAMS can provide independent technical assessment of reported electrical failures, automation faults, equipment trips or control-system problems, subject to available access, evidence, documentation and the agreed investigation scope.
Can electrical testing and maintenance records be reviewed?
Yes. Where documentation is provided, the technical assessment can include review of available electrical testing, automation testing, calibration, maintenance, inspection and certification records.
Does a visual inspection confirm complete electrical integrity?
No. A visual inspection identifies observable conditions within its scope but does not by itself establish complete electrical or functional integrity. Additional specialist inspection, measurement or testing may be required depending on the circumstances.

Yes. PAMS provides technical consultancy and independent inspection support for marine automation, monitoring, instrumentation and control systems, subject to the agreed scope and access.
Can PAMS assess offshore electrical and automation systems?
Yes. PAMS can provide independent technical assessment and consultancy concerning offshore electrical, automation, instrumentation and control arrangements within the agreed technical scope.
Does a case study determine whether equipment must be replaced?
A technical assessment can identify observed conditions and provide recommendations based on the available evidence. Final decisions concerning continued service, repair or replacement remain subject to the responsible owner, operator, manufacturer, class, flag or other competent authority as applicable.
