Scope of work
- Build of new main, emergency and group starter panels
- ACB/MCCB replacement and servicing, mechanism and operation checks
- Verification and restoration of mechanical and electrical interlocks
- Protection settings and coordination study
- Metering and logging: multi-instruments, transducers, insulation monitoring
- Shore connection panels, ATS and tie-breaker automation
- Thermographic survey and torque-controlled tightening of connections
- Cleaning, insulation restoration and corrosion protection
Typical symptoms & failures
- A breaker that will not close or charge, or needs repeated attempts
- An interlock bypassed because it 'got in the way'
- Hot busbars, discoloured connections, the smell of overheating
- Insulation monitoring permanently in fault, or switched off
- Instruments reading wrong, or not reading at all
- A switchboard with no current single-line diagram
What you receive
- Switchboard condition report with thermography and photographs
- Breaker and interlock test protocol
- Protection settings table and coordination study where required
- Updated single-line diagram
Equipment & protocols
- ACB/MCCB and protection relays from the major manufacturers
- Digital multi-instruments and insulation monitoring systems
- Thermal camera, micro-ohmmeter, primary/secondary injection test sets
- Materials and practice to IEC 60092 and class requirements
From the field
Frequently asked questions
Can main-switchboard work be done without a blackout?
Partly. Many tasks are done section by section with load transferred; anything on the busbars needs a planned shutdown.
How often is a thermographic survey needed?
Annually as a minimum, and always under load — an unloaded board shows nothing to a thermal camera.
Do you build switchboards or only repair them?
Both. New boards are built to the study and the class requirements of the specific vessel.
