Topographic Survey
An accurate assessment of the quality and position of the sludge is fundamental when planning maintenance and scheduling for a major tank cleaning task. We carry out a topographic survey of the sludge which will allow you to pursue your chosen method with confidence.
Installation
The P43® can be installed into the tank shell through existing manways without hot-work, or at the centre of the tank with hot-work. Feedlines can run from existing inlet lines or alternatively can be installed separately as a self-contained unit. In side entry applications, the patented design of the unit ensures that the nozzle, directed away from the tank side, is operational.
In a typical test, P43®s were used to resuspend approximately 2600m³ of sludge in a tank. After 15 hours operation, 2300 of these had been re-suspended. After a further 15 hours the total increased to 2500m³ – exceeding 90% efficiency.
After removal of the P43® de-sludging equipment, residues can be handled by conventional methods. Alternatively, the tank can be put straight back into operation for storing crude.
The P43® installation can remain in situ on a sale or rental basis for future two day ON LINE sludge re-suspension operations.
When permanently installed, the P43® controls sludge efficiently even while operating intermittently, depending on the conditions and characteristics of the crude oils.
