Homework Help: Electostatics question

  1. Nov 4, 2006 #1
    this is a true/false question:
    Metatllic vessel-to-shore bonding cables are connected to oil tankers.
    >>> I don't understand what "Metatllic vessel-to-shore bonding cables" means.

    When tied to a pier, boats of all kinds use some sort of rope or cable. The statement is saying that for oil tankers, cables made of metal are used.

    It is common practise to earth the fuel pipes used to put gas into the tanks of automobiles in order to prevent the buildup of electrostatic charge which could create a spark. Mooring an oil tanker with a metal cable will earth it and reduce the chances of electrostatic discharges occurring.

    Sorry, I should have mentioned that I do not know for shure whether oil tankers are moored with cables or rope.

    That being said another point to consider is the fact that sea water is a rather good conductor. This means that the tanker will be earhted anyway so that it is most likely unnecessary to use cables.
