I am writing to you to confirm that the investigation on Tank 2 – Super Diesel at Shell PINKAO SERVICE CO (B4) (1077570) has been closed as the performance of the tank has improved significantly.
A brief summary and reason for closing the investigation is as follows;
The investigation was opened on 19th June for a poor performance and decline within the terminal. The tank had a PLIP A completed on 30th June but no potential issues were highlighted in this report leading to no closure of investigation and a continuation of poor performance. I asked for the most recent nozzle calibration report to be sent in September and since mid September the tank started to show an improvement in performance and remained level with peers. The tank remains stable at present with an acceptable performance. The investigation will be closed due to data improvement.
