Records of gas carriers cargo temperature,pressure gauges-calibration of key cargo instrumentation

(1) There should be records of the regular checking and calibration of instrumentation, particularly cargo tank temperature and pressure gauges and reliquefaction plant instruments.

(2) Calibration should be carried out preferably at intervals not exceeding 30 months.

(3) Calibration of instrumentation is often difficult whilst the vessel is in service and it is usually carried out during repair periods. However, comparisons between local and remote thermometer readings and cross checking with cargo vapour pressure (from tables) provide a practical cross-reference, particularly for high purity cargoes such as Polymer Grade Propylene.
