Foreword

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"

Drafting.

This document uses the redrafting law to amend and adopt ISO 11563.2003 "Crude Oil and Petroleum Products Bulk Cargo Transfer Pipeline Filling Guidelines"

South".

Compared with ISO 11563.2003, this document has many adjustments in structure. Appendix A gives this document and ISO 11563.2003

The chapter number comparison table.

The technical differences between this document and ISO 11563.2003 and the reasons are as follows.

a) Deleted "International Oil Tanker and Oil Terminal Safety Guide (ISGOTT)" (see Chapter 4), which should not be placed in the main text;

b) The relevant content of laws and regulations has been deleted (see Chapter 4), and the drafting documents should not contain documents that require compliance with laws and regulations or policies.

Terms;

c) The content of obtaining the reference volume of the designated pipeline of the oil tanker (see 6.3.6) has been added to determine the replacement amount relatively accurately;

d) Modify the "volume required for pipeline replacement" to "approximate amount" (see 6.3.11), so that the contents of the file echo the beginning and the end.

Introduction

When crude oil and petroleum products are being transferred, the accurate measurement of the transfer volume is affected by the fullness of the cargo in the transfer pipeline and the pipeline. if

The transfer pipeline contains air or steam, or the cargo to be transferred and the cargo in the pipeline have different physical properties.

The line is filled with liquid compatible with the cargo to be transferred.
