Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Introduction
This document addresses the integrity of petroleum and natural gas pipelines through their entire
life-cycle, from design to eventual abandonment. For this reason, considerations relating to design,
construction and abandonment have been included. This approach supports the development and
implementation of a holistic and integrated pipeline integrity management program that bridges
between life-cycle elements and thereby avoids compartmentalizing of the pipeline life-cycle into
essentially independent data and functional silos, which has traditionally been the case. The integrated
approach was developed on the basis of extensive research and examination of best practices and
results from pipeline integrity audits world-wide.
This document is intended to be used by companies that have not yet developed an official program
or are developing a program for new pipelines. This document can also be used to guide continual
improvement of existing programs by both operating companies and regulators to evaluate integrity
management program effectiveness.

Part 2:
Full-life cycle integrity management for offshore pipeline
1 Scope
This document specifies requirements and gives recommendations on the management of integrity
of a pipeline system throughout its life cycle, which includes design, construction, commissioning,
operation, maintenance and abandonment.
This document is applicable to offshore pipelines for transporting petroleum and natural gas. It
is applicable to rigid steel pipelines. It is not applicable to flexible pipelines, dynamic risers or those
constructed from other materials, such as glass-reinforced plastics.
NOTE 1 An offshore pipeline system extends to:
— the first valve, flange or connection above water on platform or subsea mechanical connector with
subsea structure (i.e. manifold or dynamic riser);
— the conn
