Single Point Validation
Evaluation
■Calculate mean and standard deviation of PGC
readings.
■Add results to Control Charts and apply Decision Rules
to determine validation result.
■A result is either “GOOD” or “BAD”
■iQRM can calculates GHV and RD values acc. ISO6967
or GPA2172:1996 and cross check with PGC values.

Loading
Starting a Loading
■Trigger from DCS or other system.
■A loading prevails over a validation.
■A loading does not start when validation result is
“BAD”.
■A loading starts when validation result is “GOOD”,
even when the validation is expired.

Loading
Procedure
■Collect PGC from start to end of loading.
■PGC readings are marked as “Invalid” when:
– Loading is paused.
– LNG inlet vaporizer temperature too high.
– Sample temperature at accumulator too low.

Measurement Analysis
■Valid measurements undergo Grubbs outlier checks
on GHV.
■Average composition will be determined based on
valid measurements without outliers.
■Average calculation can be Time proportional and
Flow weighted.
