## Abstract

A bonding system for a tank battery containing a flammable or combustible product being stored or conveyed, including a bonding conductor, an electrically conductive base member mounted on the tank, the electrically-conductive base member electrically connected to the bonding conductor and to ground installed within each tank and also including a flexible conductive medium with an upper end and a lower end and a plurality of fine electrically-conductive metal wires each having a proximal end and a terminal end, the proximal ends of which are intertwined with the flexible conductive medium to be in electrical connection with the electrical conductive medium, the upper end of the flexible conductive medium electrically connected with the electrically conductive base member and a plurality of static drains located proximate to the highest points of the tank battery and electrically bonded to said bonding conductor.

## Claims

### Claim 1

A grounding system for floating roof tanks, comprising in combination:
a by-pass conductor electrically interconnecting an edge of the tank and the floating roof of the tank;
a tubular standoff comprising an elongated hollow structure through which is loosely threaded said by-pass conductor ; and
a bracket for connecting said tubular standoff to the floating roof.

### Claim 2 (depends on 1)

The grounding system set forth in claim 1, wherein said bracket comprises a unidirectional bracket whose position is dependent on the position of the floating roof which prevents the by-pass conductor from fouling on tank appurtenances.

### Claim 3 (depends on 2)

The grounding system as set forth in claim 2, further including a rim bracket fitted to an upper edge of the floating roof tank including a flexible arcuate channel that supports the by-pass conductor, defines its bending radius from the top of the tank and prevents the by-pass conductor from fouling on tank appurtenances.

### Claim 4 (depends on 1)

The grounding system as set forth in claim 1, further including an arcuate channel connected to an upper end of said tubular standoff that supports the by-pass conductor, defines its bending radius as it exits said tubular standoff and prevents the by-pass conductor from fouling on tank appurtenances.
