Commissioning should establish that the installed electrical and control system performs the required vessel functions, including the connections between equipment. Agree the testing, evidence and handover responsibilities during project planning.
Start with a shared definition of complete
Different suppliers may use “complete” to mean different things. A panel builder may mean workshop assembly and testing. An equipment supplier may mean its own machine has been checked. The operator needs the integrated application to be ready for its intended use.
Record the functions to demonstrate, documents to deliver, survey involvement and who can approve return to service. Keep commercial acceptance and regulatory decisions with their respective responsible people.
Have the responsible professionals confirm the vessel’s applicable electrical inspection, testing and record requirements, including the NSCV electrical framework (opens in a new tab) where relevant.
Understand workshop testing and onboard testing
Workshop testing can check an assembly against approved drawings and demonstrate agreed functions before delivery.
Onboard verification still needs to cover real field equipment, installed communications, operator stations and vessel interfaces. Set out those boundaries in the control-panel specification.
Define what the factory acceptance test and site acceptance test cover, who witnesses them and what evidence each produces. The labels alone do not define the scope.
Make interface checks explicit
For each connection between controls, instrumentation and machinery, identify the expected behaviour, the responsible person and the safe demonstration method.
Questions worth resolving include:
- Does the operator see the correct equipment status?
- Does the displayed measurement have the intended meaning and units?
- Are commands accepted only in the agreed operating modes?
- Is loss of information distinguishable from a normal reading?
- Are alarms understandable to the crew?
- Are local and remote operating arrangements coordinated?
Qualified people must design and control abnormal-condition and protective-function tests. These questions help set the scope; they are not instructions for testing equipment.
Arrange the people and prerequisites
Before fixing the date, confirm supplier attendance, required documents and vessel readiness. A missing OEM representative or unfinished system can stall the programme.
Nominate a coordinator. Agree who provides the procedures, safe work arrangements and authority for each activity.
Record the configuration under test. If software, equipment or settings change, have the responsible team decide which results remain valid and which tests need repeating.
Keep a useful defect list
Record each open issue, its consequence, owner and closure evidence. For example, “wheelhouse display shows the wrong units” is more useful than “finish controls”: assign the correction and require a witnessed check against the approved display specification.
Separate missing documents from undemonstrated functions. The responsible person decides whether each item blocks further testing or return to service.
Close an item when the agreed evidence exists. Keep the test record or approval with the final configuration information.
Specify the handover pack
Agree the handover pack in advance: updated drawings, equipment lists, manuals, software and configuration records, test results, applicable certificates, maintenance information and remaining limitations. The DCV survey document checklist covers organising electrical evidence.
Tell the operator where records are stored and who can access them. Transfer credentials securely, separately from manuals and general correspondence. Confirm contractual rights to software and configuration files.
Familiarise the crew with changed controls, indications and operating procedures. Plan this for the people who will use the vessel, not only the project manager.
Carry the result into normal operations
Update operating and maintenance records after handover. AMSA’s planned maintenance guidance (opens in a new tab) explains how the maintenance schedule sits within the vessel’s safety management system.
WTM works across marine electrical systems and automation and control. Discuss the project with WTM early enough to agree interfaces, verification and handover responsibilities.
