ESD-1 emergency shutdown-1 shutdown initiated when the ship moves past the warning range of allowable motion forward, aft or outward from the berth, and which initiates an LNG-ESD signal from shore to ship.
ESD-2 emergency shutdown-2 shutdown initated when the ship moves past the maximum range of alowable motion forward, aft or outward from the berth, and which initiates loading arm disconnection on shore high voltage.

fail-safe able to enter or remain in a safe state in the event of a failure [SOURCE: IEC 60050-821:2017, 821-01-10]
safety circuit normally closed interlocking circuit with pilot contacts and safety devices that shuts down the HVSC system in response to specific initiating events.connector coupling device employed to connect conductors of one circuit element with those of another circuit element.
A typical HVSC system described in this document consists of hardware components as shown in Figure 1.
Typical distribution systems used on shore are given in IEC 61936-1. Typical ship distribution systems are given in IEC 60092-503.
NOTE IEEE Std 45.1TM and IEEE Std 45.3TM provide additional information on typical ship distribution systems.
Equipotential bonding An equipotential bonding between the ship’s hull and shore earthing system shall be provided,(see 6.2.4).
In order to assure the integrity of the bonding in the shore connection,two alternative procedures are allowed:
a) Continuous monitoring of the bonding. Verification of the equipotential bonding shall be a part of the safety circuit. Loss of equipotential bonding shall result in the shutdown of the HVSC system, and the ship shall go into ship power restoration mode (see 8.6).
b) Periodic testing and maintenance of the bonding connections. Where continuous monitoring of the equipotential bonding is not in place, periodic testing and maintenance of the bonding connections shall be performed and documented (see Clause 11).IEEE 80005-1 pdf download.
