This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part

1.Structure and Drafting Rules of Standardization Documents" drafted. This document replaces GB 18180-2010 "Requirements for Safe Operation of Liquefied Gas Ships". Compared with GB 18180-2010, except for structural adjustment In addition to editorial changes, the main technical changes are as follows:

a) Changed the definition of liquefied gas, changed the term "hazardous area" to "explosive hazardous area" and changed the definition (see

b) Deleted cargo operations, insulating flanges, inter-barrier spaces, hot work, degassing, inerting, decontamination, transfer operations, transfer operations areas, Terms and definitions of unloading ships, loading ships and loading and unloading mains (see 3.3, 3.5~

3.15 of the.2010 edition);

c) The requirements for the use of hoses for cargo handling and unloading are added, and the requirements for the inspection of permanent signs before the operation of the hoses, the pressure before the hoses are used, Confirmation of the validity period of test data such as conductivity and tightness, and requirements for preventing excessive bending or twisting of the hose (see 4.1);

d) Added requirements for anti-static, anti-stray current and lighting (see

e) Four stages of loading and unloading operations on liquefied gas ships have been added, mainly including information exchange before operation, inspection before operation, loading and unloading Definition of assignments and completion stages (see 5.1, 5.2,

f) Changed the information exchanged between the two parties before the ship berthed, the information exchanged between the two parties before each loading and unloading, and the information exchanged between the barge operation ship and the ship. Information content (see 5.1, Chapter 4 of the.2010 edition);

g) Added the requirement to determine the loading and unloading plan during the pre-operation inspection stage (see 5.2.1);

h) Added requirements for ship mooring confirmation (see 5.2.2);

i) Added requirements for loading and unloading connections (see 5.2.4);

j) Changed the requirements for emergency shutdown system (ESD), monitoring alarm system and cargo handling control equipment testing (see 5.2.5,.2010 version 6.4);

1 Scope

GB 18180-2022 is the Chinese national standard on the requirements for the safe operation of liquefied gas carrier, in the field of services and company organization. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 13 July 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 February 2023.
