Tanker Loading in FranceOne of the biggest Shell petrochemical production facilities in Europe is at SHELL Berre (close to Marseille). The customer needs to load the exact quantity of SAP oil into the tanker to avoid any overloading. The trucks are then weighed on a weighbridge to get a custody transfer measurement of the mass.
If there is an overload, the truck must come back to an offloading station, losing valuable operating time. If the tanker is not totally filled, then transportation costs increase.
The previous installation was less than ideal, and 7 larger meters were replaced with Optimass T 40 and T 50 meters without any pipeline modifications. This was a requirement, as Shell was not able to stop the loading stations in order to do the work.
The measurement results were immediately excellent without any special adjustment or field calibration of the meter. For a 26 ton fill, the measurement accuracy improved to ±0.2% with Optimass from the previous ±0.8 to 2.5%!
