Advanced Online Desanding at North Sea Installation (2012-2013)
Stork completed two workscopes between 2012 & 2013 to complete online desanding on a First Stage Production Separator using the state of the art, Advanced Online Desander (AOD) Skid. The workscopes involved removal of sand from vessels during dayshift and deposit removed sand in Drill Cuttings Bins (DCB). The removed sand was washed to under 1% oil on sand during and discharged overboard.
Stork mobilized a team of five personnel and Spot, Rigged & Pressure tested equipment to the client’s satisfaction. Removed sand was washed and analyzed prior to being discharged overboard.
Results & benefits
Successfully desanded three tonnes of potentially NORM contaminated sand from the separators using the AOD Skid without the need for well shut in, vessel entry or extended shut down. Client saved significant costs and the sand removal extended the period between shut downs and maintained separator performance. Overall, this project was completed with an overboard discharge average of 0.16%, 1623ppm & zero safety incidents. A high performance standard was achieved through the efficient, safe operation from Stork’s trained and competent crew. Reflective of this is the excellent client feedback received and an average FPAL rating of 8.7 (see service code 3.05.13).
“Again thanks to Desanding Supervisor and the crew for carrying out another successful sand cleaning exercise on the Installation.”
