Calibration & Testing Services

Calibration and testing service providers check and adjust a vessel's shipboard instruments against a traceable reference standard, and carry out general testing work across a ship's systems — pressure gauge and thermometer calibration, gas detection and oxygen analyser calibration, tank gauging and sounding equipment testing, and other instrument checks needed to keep readings accurate and trusted.

This covers general instrument calibration and testing rather than the specialist proof-load testing and thorough examination of lifting appliances and lifting accessories, which is certified separately under a lifting-gear inspection regime. Providers issue a calibration certificate recording the reference standard used, the result, and the next-due date, supporting a vessel's equipment records at survey. Because instruments that read inaccurately can mask a genuine fault or lead to an incorrect operational decision, owners calibrate safety-critical instruments such as gas detectors on a fixed schedule, and buyers compare providers on calibration traceability, turnaround, and availability at the port of call.
