This paper is a follow-up of my presentation at the NSFMW in year 2000. Although there are issues to be evaluated still at the Snorre B fiscal oil export station, we can note a number of pitfalls to avoid from some non-ideal installation approaches. The experience was excellent with the first two Krohne Altosonic-V ultrasonic liquid meters installed offshore, Serial Number 1 and 2 at Snorre-Vigdis Crossover, where one of the ultrasonic meters was used for master transfer in the frequent calibrations. Then applying a turbine meter for master transfer from the Compact Prover in the annual third party calibration. This led to the next step of expecting that a turbine meter could also be used for the frequent verifications of the duty ultrasonic meter at the Snorre B fiscal oil export station. I will recapitulate the scepticism for the Snorre B fiscal oil metering installation, some of which was presented at NSFMW in 2000.
