Scope of work
- Technical survey of the existing installation and condition assessment
- Upgrade proposal that states plainly what stays, what is replaced and what is removed
- Replacement of obsolete controllers, relays and instruments with current equivalents
- Modernised generator control and PMS without replacing the switchboard
- AMS and engine-room screen upgrades
- Migration from analogue instruments to digital metering and logging
- Replacement of ageing inverter / VFD drives and starters on cargo pump fans, thrusters and pumps
- Reconstruction of documentation: single-line, control drawings, I/O lists
- Phased scheduling so the vessel keeps trading
Typical symptoms & failures
- Spares that cannot be sourced, or only second-hand
- Units with no manufacturer support and no documentation
- Drawings that do not match the installation
- The same failures recurring in the same places for years
- No capacity to add a new load or a new machine to the existing system
What you receive
- Survey report with photographs and equipment condition
- A phased proposal with estimated downtime per phase
- Full as-built drawings on completion
- Commissioning protocol and a recommended spares list
Equipment & protocols
- Current-generation generator controllers and protection units
- Digital multi-instruments, transducers and recorders
- Industrial PLCs and HMIs replacing relay logic
- Materials and practice to IEC 60092 and class requirements
Frequently asked questions
Does the whole switchboard have to be replaced?
Rarely. In most cases the enclosure, busbars and breakers are sound; what has become obsolete is the control and metering.
Can a retrofit be done without drydocking?
Many control upgrades are done in port stays, in phases. Anything requiring a main-switchboard shutdown is planned around docking.
What if there are no drawings?
We produce them. Surveying the existing wiring is part of the job, and is often the most useful deliverable of the project.
