Inspector Detail

▸

Common issues

Sensor drift or inaccurate level readings from condensation, coating buildup or gas density changes affecting radar or electropneumatic transducers
Loss of communication between field transmitters and the central control unit from cable faults or corroded junction boxes
Float or displacer sticking in electropneumatic tape systems causing frozen or erratic readings
Power supply or UPS failures taking the whole gauging loop offline
Alarm mapping errors after partial firmware or software upgrades
False high-high or low-low alarms from moisture ingress into pressure transmitters
Spares and firmware support becoming scarce as Kongsberg phases this generation of hardware out

Inspection checklist

Verify each tank level reading against an independent manual sounding or ullage
Check transmitter and sensor housings for corrosion, cracked cable glands and water ingress
Confirm high level and high-high level alarm setpoints against the cargo or ballast operations manual
Test alarm audible and visual annunciation at the control console and remote repeater panels
Inspect junction boxes and cable runs for chafing, corrosion and proper gland sealing
Verify UPS or battery backup autonomy and charge condition for the gauging system
Check calibration records and last calibration date for each tank sensor
Confirm software or firmware revision matches the vessel's approved configuration record
Function-test the independent overfill alarm where fitted

Service intervals

Sensor and transmitter calibration check	annually or per manufacturer schedule
Alarm function test, all tank alarms	before each cargo operation
UPS or battery backup check	annually; batteries typically renewed every 3-5 years
Cable and junction box inspection	annually
Software or firmware revision review	at each planned maintenance survey

Critical spares

Level transmitter or sensor unit matched to the tank sensing type fitted, radar or electropneumatic
Junction box terminal and cable gland kit
UPS battery set
Local display or repeater unit
Alarm relay or interface card
Screened marine-grade signal cable

Safety

Relying on a single gauging system without independent overfill protection can allow cargo tank overfilling and spillage
Pressurised electropneumatic sensing lines - isolate air supply before disconnecting
Electrical work on transmitters in hazardous zone areas requires intrinsically safe tools and a valid permit
An uncalibrated system can give false confidence - always cross-check against manual sounding before critical operations

Class survey

Class surveyors typically confirm that high-level and independent overfill alarms remain functional and calibrated, and that alarm test records are maintained; on Continuous Survey Machinery the gauging and alarm functions are checked against the vessel's planned maintenance records.
