The Kongsberg Common Control Platform (CCP) covers marine controllers such as the H6045, H6059 (type H1151) and H1170, supplied under CCP projects 141004, 141007 and 141009. These are programmable controllers for machinery and safety-related control tasks, installed in control cabinets, and listed with DNV and IMO IGF Code approvals. The IGF Code listing indicates use in the control and safety systems of gas-fuelled ships.

Service

Service notes.

What our service work and the manufacturer documentation say about keeping this model running.

Check power supplies, I/O modules, communication links, alarms and cabinet cooling, and test safety and shutdown functions at the intervals set by the maker and class. Surveyors normally review software version control, backups, and function testing of gas-related safety systems under the IGF Code where applicable.

Inspection

Common failures & inspection points

Inspection

Inspector Detail

Common issues

  • Sensor drift or failure on tank level, pressure or temperature transmitters feeding the control system
  • Communication/network faults between the controller and field instrumentation or the integrated automation system
  • Software/firmware faults requiring reboot or reload, especially after a power interruption
  • Gas detection sensor calibration drift affecting alarm reliability
  • Valve actuator feedback discrepancy between commanded and actual position
  • BOG (boil-off gas) management logic faults causing incorrect venting or compressor sequencing
  • Power supply or UPS backup failure affecting control system availability

Inspection checklist

  • Verify all tank level, pressure and temperature readings against independent local instrumentation
  • Check gas detection system calibration certificates and function-test alarm points
  • Confirm valve position feedback matches commanded state for cargo, vent and BOG valves
  • Test alarm and shutdown functions (high level, high pressure, low temperature) per maker procedure
  • Verify UPS/backup power supply function and battery condition
  • Check communication link status between the controller, field devices and the integrated automation system
  • Review the alarm and event history log for recurring or unresolved faults
  • Confirm software/firmware version matches the maker's approved configuration
  • Inspect the control cabinet for condition, cleanliness and secure cable terminations

Service intervals

Gas detection sensor calibrationper maker/class requirement, typically every 6-12 months
UPS battery check/replacementper maker manual, commonly every 2-4 years
Software/firmware version reviewat each planned maintenance or class survey
Sensor/transmitter calibration check against an independent referenceannually or per maker schedule
Alarm and shutdown function testannually, per class requirement for cargo containment safety systems

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Critical spares

  • Spare pressure, level and temperature transmitters matching the system's approved type
  • Gas detection sensor heads/cartridges
  • Control cabinet fuses, relays and power supply modules
  • UPS batteries
  • Valve actuator position feedback sensors

Safety

  • Reliance on a single control system for cargo containment safety - always confirm independent local instrumentation before manual intervention
  • Cryogenic hazard from the cargo if manual valve operation is required following a control system fault
  • Confined space and gas hazard considerations if fault-finding requires access near cargo tank penetrations
  • Electrical hazard when opening control cabinets - isolate per permit-to-work

Class survey

Cargo containment control systems on gas carriers are surveyed against the IGC Code - function tests of high-level/high-pressure alarms and shutdowns, gas detection calibration records, and confirmation the approved software/firmware configuration is unchanged since the last survey.

Estimated lifetime: Controller units and I/O modules are commonly kept in service 15-20 years with periodic module-level replacement rather than full-life wear-out; obsolescence of electronic components is often the practical limit rather than mechanical wear - confirm against the maker's support/end-of-life notices.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
