Kongsberg Marine automation system, K-Chief
Our K-Chief solution is the ultimate choice for shipowners and operators seeking seamless integration and enhanced operational safety when using multiple KONGSBERG systems. With decades of experience delivering marine automation systems for merchant and offshore vessels, Kongsberg Maritime provides solutions contributing to efficient and safe operations. Experience next-level efficiency with our latest K-Chief technology, building on the success of K-Chief 600 and K-Chief 700 Our K-Chief marine control system is the ultimate choice for shipowners and operators seeking seamless integration and enhanced operational safety when using multiple Kongsberg Maritime systems. Our cutting-edge, redundant bus network maximises system reliability, while interchangeable operator stations and shared spare parts minimise crew training and maintenance. We offer single-point accountability and broad service network to ensure smooth sub-system synergy, lower service attendance, and minimise costs. K-Chief is an all-in-one marine automation system combining innovation, safety, and efficiency. K-Chief marine control system can include a variety of sub-systems and functionalities for extensive vessel management capabilities. K-Chief is a popular and proven marine automation system, and this latest version combines the strengths of our existing platforms to provide shipowners and operators with a better technical and operational solution, and improved integration when they’re selecting more than one system from Kongsberg Maritime. It provides the basis for one common platform on board the ship to integrate the Kongsberg Maritime equipment. For the crew, this simplifies operations making their job more efficient, easier and safer.
Inspector Detail
▸
Common issues
- Alarm flooding from poorly tuned setpoints, which trains crew to ignore alarms over time
- I/O card failures causing loss of individual signals rather than a full system outage
- Network switch or HMI workstation failure affecting redundant data paths
- UPS battery degradation reducing backup runtime below rated capacity
- Sensor calibration drift feeding false or delayed readings into the system
- Loose terminal connections from vibration causing intermittent signal dropouts
- Software/firmware version mismatches after a partial upgrade causing display or logging errors
Inspection checklist
- Run a full alarm system functional test and compare against the alarm list
- Check UPS battery condition and verify backup runtime against nameplate rating
- Inspect I/O cabinets for loose terminals, corrosion, or moisture ingress
- Test failover between redundant network paths (dual LAN) where fitted
- Check HMI workstation/server disk health and confirm configuration backups are current
- Cross-check key sensor readings against an independent reference instrument
- Verify environmental conditions (temperature, humidity) in the electronics room
- Confirm installed software/firmware version against the class-approved baseline
- Verify emergency stop and safety-system overrides operate and log correctly
- Check cable gland and enclosure sealing integrity
Service intervals
| UPS battery replacement | typically every 3-5 years or on failed capacity test |
| Alarm/monitoring functional test | typically each voyage or per the vessel's SMS schedule |
| I/O and sensor calibration check | typically annually |
| Configuration backup and restore test | typically every 6-12 months |
| Network switch and cabling inspection | typically annually |
Typical wear limits
| UPS backup runtime | flag for battery replacement once measured runtime falls to roughly 50-60% of the nameplate rating |
| I/O loop insulation/continuity | check against the commissioning baseline where records exist; a significant drop signals cable or terminal degradation |
| HMI/server disk health (SMART status or equivalent) | flag for replacement on any reported reallocated-sector or predictive-failure warning rather than waiting for an outright failure |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Critical spares
- Analog and digital I/O cards (as fitted)
- Power supply modules
- Network switches
- UPS batteries
- Spare HMI workstation or PC
- Terminal blocks and cabling/connectors
Safety
- Loss of alarm/monitoring function can mask a developing machinery fault - any bypass or override must be logged and removed as soon as possible
- Electrical hazards inside open I/O cabinets and power supply units
- Automation should never fully replace local gauges and manual checks for critical parameters
- Configuration or software changes must be tested before being applied to a live system underway
Class survey
Class typically checks that alarm and safety-system function tests are performed and logged, that any bypassed or overridden alarms are documented and time-limited, and that software/configuration changes affecting safety functions are recorded and, where required, approved.
