This standard specifies the requirements for the design and construction of pipelines used for the transmission of liquids such as:. All comments received electronically by the due date will be put before the relevant drafting committee. An equation for calculating the thickness required for external pressure is provided. A revision of the requirements for effective pipeline marking including a change to require the marker sign to comply with a Danger sign in accordance with AS A Plan for Isolation of a Pipeline. The SAOP shall identify that these actions arose from the risk management study and are an integral part of pipeline risk management.

Materials shall be specified, qualified and inspected in accordance with Section 3. Modes of failure include rupture as a running crack in brittle fracture mode, rupture as a ductile tear, hole, pinhole, crack, dent, gouge, loss of wall thickness. Where appropriate, changes will be incorporated before the Standard is formally approved.
ASGas transmission and distribution systems is currently undergoing revision and will be published as a distribution pipeline standard, and as2885.11 been deleted as a reference standard.
As 2885 1 Pipeline
Operation and Maintenance Part 4: Where the pipeline route or its design has been changed during construction, the compliance of each change with the requirements of this Standard shall be established. Thank you for interesting in our services.
Sa2885.1 for low temperature excursions. A small LPG leak which is initially unignited may well have a higher consequence or higher risk ranking than a as28855.1 immediately ignited release. Procedural external interference protection for the full length of the pipeline shall be designed in accordance with Section 5.
The SAOP shall identify that these actions arose from the risk management study and are an integral part of pipeline risk management.
The output of this process is a design generally shown on alignment sheetsand a risk management study document generally recorded on a database. Please consult the responsible agency for more information and to ascertain the level of compliance if any that may be required.
It is intended that this process be as288.51 when assessing alternative methodologies to mitigate environmental risk through pipeline planning, design, construction and operating phases of its life, irrespective of the existence of other environmental assessment methodologies.
General Requirements Part 1: For external interference threats, external interference protection measures shall be applied. If the draft is acceptable without change, an acknowledgment to this effect would be appreciated.
Size px x x x x The risk management study shall be undertaken by personnel with expertise in each component of as285.1 design, construction and operation of the pipeline, including, or with the support of, personnel closely familiar with the land uses and environments along the entire route. The information requirements listed in Section 2.
as285.1 The principles established for risk management for pipeline failure are used to provide guidance on environmental risk management. The coordination of the requirements of this draft with those of any related Standards is of particular importance and you are invited to point out as288.1 areas where this may be necessary.
Protection against construction related defects shall be in accordance with Section Operational controls for the full length of the pipeline shall be designed in accordance with Section 7. The application of the risk management process is an integral part of pipeline system design, and cannot be performed independently from the design process.
This combination of the characteristics of the threat and the characteristics of the pipeline is called failure analysis. Design and construction To be AS Additional guidance as28885.1 provided on treatment ss2885.1 lightning, together with some clarifying revisions to the text. These organizations are listed on the inside back cover. Risk database, GIS can greatly assist both in process of risk assessment and in documenting its deliberations and outcomes, and allowing decisions to be made transparently.
It shall consider at least: Risk management documentation shall be transferred from the design and construct phase of the project to the operating phase of the project in a form that enables risk management to be undertaken from the time that operation commences.
The section establishes a structured methodology for demonstrating the pipeline fitness and once approved, for commissioning the pipeline at the new pressure. Each failure event shall as285.1 subjected to risk evaluation and risk control.
This standard specifies the requirements for the design and construction of pipelines used for the transmission of liquids such as:
