ISGOTT draws attention to the risk of electrostatic potential in a mist produced by using oil and water mixture in Crude Oil Washing operations. How does the Guide recommend this is avoided?
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 af any cargo compartment is commenced.
Crude Oil Washing, where the oil source is stored in a slop tank or other tank that has previously contained slops, should be avoided.
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 metreis necessary for this purpose.

The tie rods should be fully tensioned before the jacking bolts are loaded to avoid overload of the bearing caps and frame structure.
The tie rods and jacking bolts must be tightened simultaneously to avoid excess load on either component.
