Please help us to share our service with your friends. It was 2885.1 on behalf of the Council of Standards Australia on 27 July This Standard was published on 20 September The following are represented sa Committee ME Standards Australia wishes to acknowledge the participation of the expert individuals that contributed to the development of this Standard through their representation on the Committee and through the public comment period.
To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments that may have been published since the Standard was published.
Detailed information about Australian Standards, drafts, qs and new projects can be found by visiting www. Revised and redesignated AS — AS first published Second edition AS — Second edition AS Third edition AS No part of this work may be reproduced or copied in any form or by any means, electronic or mechanical, including photocopying, without the written permission of the publisher, unless qs permitted under the Copyright Act The objective of this Standard is to provide requirements for the design and construction of steel pipelines and associated piping and components that are used to transmit single-phase and multi-phase hydrocarbon fluids.
This Standard provides guidelines for use of pipe manufactured from certain non-steel or corrosion-resistant materials. This Standard is part of a series that covers high pressure petroleum pipelines, as follows: General requirements Part 1: Design and construction this Standard Part 2: Operation and maintenance Part 4: Field pressure testing Accessed ass Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed —Minor revision harmonization with other parts This minor revision of AS Significant changes ae this edition include ae following: Only minor clarifications have been addressed.
Complicated clarifications have been reserved for the next revision of AS The amendment includes guidance on specifying fracture toughness when purchasing line pipe and includes a simplified calculation for energy release from leaks.
The requirements for the control of fracture initiation in components other than line pipe have been clarified.
These issue papers were debated within the subcommittee and published on the Industry web site to allow consideration by the Industry. The results of these deliberations form the basis of this revision. The revision also reflects the results of a significant and ongoing industry funded research program undertaken by the Australian Pipeline Industry Association and its research contractors, and through its association with the Pipeline Research Council International and the European Pipeline Research Group.
This revision provides a basis for Industry to benefit through the application of an increased factor for pressure design for new pipelines and a structured basis for increasing the MAOP of a qualifying existing pipeline. These benefits are supported by robust requirements for safety, structural design, construction, testing and record keeping.
Significant changes in this revision include the following: This revision provides more explicit guidance on the obligation to undertake safety assessments with the integrity required for compliance with this Standard. Material is provided in normative and informative appendices.
The use of fibreglass and corrosion resistant alloy pipe materials for pipelines constructed to this Standard is permitted and limited in this Section.
A minimum toughness requirement for pipe DN and larger has been introduced. The Section has been expanded to include the following: Provisions for compliance with these requirements for pipelines constructed to this edition, or to an earlier revision, of the Standard, in land where the location classification has changed to residential or equal is included.
Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed vii Provisions for low temperature excursions. Significant changes to this Section include the following: The thickness terms used in this Standard are clarified. The limits for each stress condition are tabulated and normative and informative appendices are provided incorporating the relevant equations.
Reliability and limit state design methods are permitted for pipeline design and integrity analysis, using approved methods. The Section has been expanded to require the Design Basis for stations to be documented. Additional guidance is provided on treatment of lightning, together with some clarifying revisions to the text.
The requirements for pipeline operation under transient conditions and a tolerance specification for pressure controls on pipelines intended to be operated at MAOP are addressed. The Section incorporates clarifying a. The Section establishes a structured methodology for demonstrating the pipeline fitness and, once approved, for commissioning the pipeline at the new pressure. The maximum pressure is limited to the hydrostatic strength test pressure divided by the equivalent test pressure factor.
The requirements for construction survey are clarified, and 2885.1 minimum accuracy for asconstructed survey is incorporated. 2885.1 padding and backfilling are two activities that impact on the pipeline integrity, this revision incorporates additional requirements for these activities reflecting outcomes from APIA research on backfilling.
It specifies strength test endpoint requirements for pipelines with a pressure design factor of 0. Obligations on the developer of a new pipeline to document the design and construction, and to transfer this information to the pipeline operator, are clarified and expanded.
New appendices are provided reflecting the findings of APIA research, clarification of concepts in the Standard, ax providing detailed calculation methods. In addition to the items identified above, there are a great many xs of lesser significance incorporated in the document to the extent that users should consider it as a familiar but new Standard. Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of the Standard.

The principles are expressed in practical rules and guidelines for use by competent persons. These fundamental principles and the practical rules and AS Documents nominated in this Standard as requiring approval shall be approved by the Licensee and not delegated. Where approved, this Standard may also be used for design and construction of pipelines made with corrosion-resistant alloy steels, fibreglass and other composite materials. Where this Standard is used for pipelines fabricated from these materials, appropriate requirements shall be established to replace the provisions of this Standard in relation to nominated Standards for materials Section 3fracture control Clause 4.
For composite material, appropriate requirements shall be established to replace the hydrostatic strength test endpoint provisions of AS As provided in AS Where this Standard is applied to fluids other than gas and liquid petroleum, a gap analysis shall be conducted to identify the differences between the www. This revision AS Each existing pipeline shall be assessed against the requirements 8285.1 Clauses 4.
Where the existing pipeline does not comply with either Clause, mitigation shall be applied in accordance with Clause 4. Approval requires a conscious act and is given in writing. When the defect is smaller than this length, the pipeline will leak. A critical defect length also exists for part through 288.1 flaws. It is emphasized that failure is not restricted to loss of containment. The Licensee is generally the organization named in the pipeline licence issued by the Regulatory Authority.
The credibility or otherwise of a threat is a characteristic of the threat itself and is assessed independently of any protective measures that may be applied to mitigate it. A noncredible threat is not the aa as a credible threat that has been controlled. The purpose of the test is to eliminate the risk of failure of the pipe during the strength test. Pressure strength for a pipeline or a section of a pipeline is the minimum of the strength test pressures of the test sections comprising the pipeline or the section of the pipeline.
All threats to 2885. integrity of the pipeline shall be identified and multiple independent controls shall be applied to each identified threat.
This Standard recognizes the hierarchy of effectiveness of controls: Mandatory requirements are specified for control of external interference threats which are known to be the most frequent events with the potential to create a failure.
Mandatory requirements 2885.1 specified in high consequence areas for— i elimination of rupture; and ii maximum energy release rate.

285.1 Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed Where land use changes from a low consequence area to a high consequence area, 2885.1 Standard applies mandatory requirements for maintaining the risk at an acceptable level. The safety management study shall include stations, pipeline facilities and control systems.
The process safety of stations, pipeline facilities and control systems shall also be reviewed by HAZOP and, as appropriate, by other recognised safety study methods. The 2885.1 management process involves two stages: A Design and Safety Review in accordance with this Standard.
The Licensee shall ensure that pipeline safety management activities are carried out by suitably qualified, trained and experienced personnel. The safety management process and its outcomes shall be documented and approved. Pipeline safety management shall be an ongoing process over the life of the pipeline.

Safety controls require continuous management so that they remain effective. The outcomes of the safety management study shall be incorporated in the pipeline management system.
This Standard includes requirements for management of construction safety, electrical safety and environmental impacts. For new pipelines, or modifications to existing pipelines, the detailed design and the safety management study are undertaken as integrated iterative processes. The output of these processes is a design generally shown on alignment sheetsand a safety management study document generally 285.1 on a 2858.1. The pipeline management system shall identify these actions including the implementation of specific risk management actions as an integral part of pipeline safety management.
