A service company, based in the Gulf of Mexico, that provides dockside cleaning of offshore supply vessels (OSV) used 5 bbl of SAS PitClean 102C product to clean 4 x 600 bbl tanks in 4 hours and recover over $15,000 worth of oil.
The Problem:
The OSV had been decommissioned due to extensive clogging of the gun-lines from previous attempts to lance the vessel using competing cleaning products. The service company's client was extremely anxious to get their vessel back in service as soon as possible, fully cleaned with all trace of drilling fluid and mud removed.
The OSV was configured with 4 x 600 bbl mud tanks shipping synthetic based mud. Up to 24" of packed barite was found on the bottom of tank #1, overlaid with approximately 40 bbl of pump-able mud. Tanks #2, #3 and #4 contained up to 6" of packed solids each with approximately 20 bbl of pump-able mud above the settled barite.
