SYSTEM AND METHOD FOR MONITORING ELECTRICAL GROUND CONDITION BETWEEN A MARINE VESSEL AND A LOADING-OFFLOADING FACILITY

摘要

A Ship Board Ground Monitor System measures an antistatic bond between a ship and a loading-off-loading facility during operation and an earth ground while in the process of loading or unloading flammable materials.;The system ensures that a maximum adjustable, preset resistance between the ship transport and safety ground is not exceeded. Should this resistance be exceeded, the control apparatus within the system will activate audible and visual annunciation and provide a contact output, which may be used to disable pumping systems.

1. A system for monitoring an electrical ground condition between a marine vessel partially disposed in a body of water and at least one of an earth and a loading-offloading facility, said system comprising:
(a) a control apparatus; (b) a grounding cell device positioned in a contact with the earth; (c) a first connection between said control apparatus and said grounding cell; (d) a second connection between said control apparatus and at least one of a loading-offloading facility structure portion and a ground support member inset into the earth and supporting the loading-offloading facility above a water line; and (e) whereby said system is configured to monitor a resistance differential between the marine vessel and the at least one of the earth and the loading-offloading facility structure.
