PRACTICAL AND COMPUTER ASSESSMENTS OF IGNITION HAZARDS DURING TANK WASHING AND DURING WAVE ACTION IN PART-BALLASTED OBO CARGO TANKS
The theoretical, experimental and practical studies which were carried out at Culham Laboratory up to March 1973 on the mechanisms by which electrostatic hazards arise in the operation of large oil tankers are described. Theoretical calculations show that hazardous sparks (with energy above 0.2 mj) can be expected when fairly modest sized slugs of water, perhaps as small as 100 mm long, 20 mm diameter, arrive at a projection such as a washing machine in a tank filled with a typical charged mist. Hazards can also be expected during sloshing in part- ballasted tanks. Experimental studies show that the incendivity of electrostatic sparks is affected by the velocity of approach of the discharge surfaces. Radio techniques have been developed for monitoring the occurrence of electrostatic sparks.
