Grounding on Offshore Metallic Structure


On a fixed offshore oil & gas structure which is completely metallic, is there any need for a common bonding network, if each equipment is bonded to the metallic structure by cad weld?


According to IEC60079-14 §6.3 all exposed and extraneous conductive parts shall be connected to the equipotential bonding system which is normally the steel structure.
It is however not required to use seperate conductors if the parts are firmly secured and in conductive contact whith the equipotential bonding system which is the case with a welded connections.

Above is a snippet.
