The American Petroleum Institute has published the API Manual of Petroleum Measurement Standards Chapter 12.1.1 – Calculation of Static Petroleum Quantities – Upright Cylindrical Tanks and Marine Vessels Part 1 as fourth edition in February 2019.
QuantityWare has carefully analysed this new edition and confirms that all BCS MQCI Crude Oil & Products Calculation Models, which are in compliance with the third edition, do also comply with the fourth edition of API MPMS Chapter 12.1.1 Part 1. Note that SAP Tank Management Calculations are also affected by this standard, for which QuantityWare cannot make any technical compliance statement.
