Project Overview
Systematic fault-finding and repair of a low-voltage distribution and control circuit associated with the vessel’s main switchboard.
Operational Challenge
The vessel experienced intermittent trips and unreliable operation of an essential electrical consumer. The fault was not consistently repeatable, requiring structured diagnosis rather than replacement of components without evidence.
Technical Assessment
The team reviewed single-line diagrams, alarm history and operating conditions. Visual inspection, insulation-resistance testing, continuity checks, control-voltage verification and targeted measurement of suspect circuits were carried out.
Detailed Scope of Work
- Review of electrical drawings and alarm history
- Visual and thermal-condition inspection where available
- Insulation-resistance and continuity testing
- Verification of control power and protective circuits
- Inspection of terminals, contactors, relays and breakers
- Correction of loose, damaged or overheated connections
- Replacement of defective components subject to approval
- Functional testing, trip verification and monitoring
Execution Methodology
The affected feeder and control circuits were safely isolated. Connections and components were checked in a logical sequence to identify the fault path. Defective or degraded elements were corrected, terminals were retightened to appropriate values, and the circuit was tested through multiple operating cycles.
HSE Controls
Electrical isolation, lockout/tagout, test-before-touch and appropriate arc-flash precautions were applied. Live testing was limited to controlled diagnostic steps carried out by competent personnel.
Quality Assurance and Inspection
Pre-repair and post-repair readings were documented. Functional tests confirmed correct operation of interlocks, alarms, indications and protective functions associated with the repaired circuit.
Project Outcome
The intermittent fault was eliminated and the affected consumer returned to reliable service. The vessel received a clear record of findings and recommended follow-up maintenance.
Typical Close-Out Deliverables
