Using measurements from individual voyages provided by HMC-4A committee members, measurement differences including Bill of Lading vs Outturn and ship/shore comparisons are calculated each year for the majority of traded crude oil grades.

The data is reported to members by grade, load port, discharge port and vessel; focusing on the loss and standard deviation at each stage of the voyage.

Examples of the data (analysis by grade) can be viewed through the measurement link. Please contact if you would like more details about the committee.
