ELECTROSTATIC TESTS DURING CARGO TANK WASHING ON THE JAMES E. O'BRIEN

"O'Brien" tests were a comparative study which investigated the effect of tank size on the magnitude of static charge buildup during tank washing, compared the operation of the shell and modified Smith field meters, and inspected for sparks during operations. Under actual tank-washing conditions, tests indicated that tank size contributed to the magnitude of static charge buildup, that the Shell axial field meter indicated fields 3X as high as the A.O. Smith field meter due to differences in sensing vanes, and that no sparking was observable.
