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.
In addition to discussing the requirements of the IGC Code, this document recommends additional measures for linked ESD systems for LPG. An overview of the types of ship shore link systems that are typically used in the industry is provided in the annexes, including guidance for cyber security issues associated with linked ESD systems.
This new document updates and replaces the previous publication, ESD Arrangements & Linked Ship/Shore Systems for Liquefied Gas Carriers (2009).
