18.10.1.1 A cargo emergency shutdown system shall be fitted to stop cargo flow in the event of an emergency, either internally within the ship, or during cargo transfer to ship or shore. The design of the ESD system shall avoid the potential generation of surge pressures within cargo transfer pipe work (see 18.10.2.1.4).

Emergency shutdown (ESD) is a design feature that is used in process systems to reduce risk. In the liquefied gas industry, ESD is a safety system that is designed to minimise the consequences of an incident. This document is the outcome of a review of …

The term ESD valve means any valve operated by the ESD system. ESD valves shall be remotely operated, be of the fail closed type (closed on loss of actuating power), shall be capable of local manual closure and have positive indication of the actual valve position.

7.1.1 An emergency shutdown (ESD) system represents a layer of protection that mitigates and attempts to prevent a hazardous situation from occurring. An ESD system is to be provided when any process presents a hazard which could affect the safety of personnel, the overall safety of the unit or the pollution of the environment.

The emergency shutdown (ESD) system is a requirement of the IMO code for the carriage of liquefied gases in bulk and is a recommendation of SIGTTO. It is fitted to protect both the ship and terminal in the event of power loss, cryogenic or fire risks, on either the ship or in the terminal.

The emergency shutdown (ESD) system is a requirement of the IMO code for the carriage of liquified gases in bulk and is a recommendation of SIGTTO. It is fitted to protect the ship and terminal in the event of cryogenic or fire risk, on the ship or at the terminal.

SIGTTO has produced this guidance note due to members’ concerns about the different interpretations of the functional requirements for ESD systems, particularly those differences between the needs of the LNG industry and those of the LPG industry and how these may interact with linked ship/shore shutdown systems.

2023年12月13日 · esd，是英文emergency shut down的缩写，通常翻译成“应急切断”系统。 根据《IGC规则》要求，液化气船舶应设有货物应急切断系统以在紧急情况下（船舶内部或货物驳运至船上或岸上时）停止货物流动。

Emergency Shutdown (ESD) system ESD systems execute a sequential shutdown of ship or terminal pumps and valves in an emergency. ESD systems shut down the cargo transfer operation in a quick and controlled manner by closing the shutdown valves and stopping the transfer pumps and other relevant equipment.

This document provides recommendations for ESD and related safety systems, including overflow control, ship shore link and emergency release systems. Guidance for testing these systems is provided and bowties are used to help explain the IGC Code requirements.
