This document is modified to adopt ISO 20257-2:2021 "Liquefied natural gas plants and equipment – Design of floating liquefied natural gas plants" Part 2: Particular requirements for floating storage and regasification units:

Compared with ISO 20257-2:2021, this document has many structural adjustments: A comparison of the structural number changes between the two documents See Appendix A for the table:

This document has many technical differences compared to ISO 20257-2:2021:

A list of these technical differences and their reasons is given in Appendix B:

The following editorial changes were made to this document:

--- Added examples of dry chemical fire extinguishing systems (see 5.3:5:2:5), scope of application of mooring positioning systems (see Chapter 6), and Detailed description of "Region" (see 9.2:4:2), pressure vessel specifications (see 10.3);

---Replace the concentration unit from ppm to mg/L (see 5.2), and the pressure unit from bar to Pa [see 10.2, C:3:2a)];

--- Deleted the reminder of the probability of major accidents (see 5.3:4:1), referenced NPFA standard (see 5.3:5:2:2), 5:3:5:3:1 items Notes in e) and f) (see 5.3:5:3:1), LNG custody transfer guidelines (see 9.3);

--- EN 13645 (see 5.3:5:2:1) is replaced by the informative reference IMO 951 (23), GB/T 21412.2 replaces ISO 13628-2 (see 9.2:2:3) and GB/T 16647 replaced ISO/IEC 10027 (see 9.2:2:3):

Introduction

The purpose of this document is to establish the design and construction of floating liquefied natural gas plants and equipment applicable to floating liquefied natural gas plant projects:

Professional design criteria such as process, cryogenic piping, automatic control, safety and environmental protection provide functional support for the design of floating liquefied natural gas (LNG) devices:

GB/T 43130 "Liquefied Natural Gas Plants and the design of a floating liquefied natural gas unit is proposed to consist of two parts:

--- Part 1: General requirements: The purpose is to provide general requirements for all floating liquefied natural gas units (including liquefaction, storage, evaporation, transfer and treatment Provides functional guidance for the design and operation of plants for handling liquefied natural gas:

--- Part 2: Particular requirements for floating storage and regasification units: The purpose is to provide specific requirements for floating storage and regasification units described in GB/T 43130.1:

It provides specific requirements and guidance for the design and operation of a FSRU:

FSRU is a widely used floating liquefied natural gas unit that has the functions of receiving, storing and regasifying liquefied natural gas, as well as delivering it to land:

The function of natural gas pipeline transportation and metering: The general requirements for the design of floating liquefied natural gas units have been specified in GB/T 43130.1 this document supplements the FSRU special design requirements: This document does not specify the FSRU propulsion unit settings and special Requirements for establishing a regulatory system:

When a self-propelled FSRU is used as a liquefied natural gas carrier, the technical requirements for liquefied natural gas carriers shall be referred to:
