VOLTAGE DIFFERENTIAL REDUCTION METHODS USED WHILE RETRIEVING A MOBILE PLATFORM FROM A TANK CONTAINING A HAZARDOUS, NON-CONDUCTIVE SUBSTANCE

A mobile platform uses a charge accumulation control system to control a charge accumulation while the mobile platform is in the tank. Alternatively or additionally, the mobile platform includes a retrieval system having a buoyant body, a primary tether, and a secondary tether. Alternatively or addi...

Zusammenfassung:A mobile platform uses a charge accumulation control system to control a charge accumulation while the mobile platform is in the tank. Alternatively or additionally, the mobile platform includes a retrieval system having a buoyant body, a primary tether, and a secondary tether. Alternatively or additionally, an electrical cable is used to reduce a voltage difference between the mobile platform and the tank or other structure by electrically connecting to an electrically conductive member on the mobile platform.
