The recommended guideline for avoiding the risk of electrostatic potential in a mist produced by using oil and water during Crude Oil Washing operations is that:

If a slop tank is to be used to supply oil to drive a Crude Oil Washing operation in a cargo tank, then that slop tank must not have contained slops with a water content of more than 2 %.

As washing begins, any water observed in the stream should be diverted to a slop tank, before Crude Oil Washing of any cargo compartment is commenced.

Before washing begins, any tank that is to be used as a source of oil for Crude Oil Washing should be partly discharged to remove any water that has settled out during the voyage. The discharge of a layer of at least 1 metres necessary for this purpose.

Crude Oil Washing, where the oil source is stored in a slop tank or other tank that has previously contained slops, should be avoided.
