AS 2885 Parts 0/1/6: what do I need to know?

 

Question:  What do I need to know about AS 2885 Parts 0/1/6?

Answer: “that depends”.

It depends on your role, experience, knowledge, background, and typical use of the Standard.

But here are some hints.  This is not an exhaustive list, this is my list.

In addition to this, a more formal (and more informational) article is being written by Peter Tuft for the February 2019 edition of the Pipeliner, which will have other details and explanations.

The APGA Technical Seminar being held March 13-14 in Sydney will highlight other changes.

And if you call another Committee member and ask them what they think you need to know about the new Standards, they’ll give you another list.

So, what do you need to know?  It just depends.

Basics:

  1. Part 0 now includes common defined terms, and Parts 1 and 6 refer to Part 0 for definitions.  There are no definitions in Part 1 or Part 6.  Defined terms are now easily identified by “Small caps” format in Parts 0, 1 and 6, for which the user will then have to go to Part 0 for the definition text.
  2. Part 1 now only addresses new pipelines or modifications; references to existing pipelines have largely been removed (and will reside in the 2019 version of Part 3 (Operations).
  3. The new Part 6 encompasses all aspects of pipeline safety management for a pipeline lifecycle.  The principles and process for the SMS approach have not changed.  Guidance has been enhanced and extensive information provided to assist with the process.
  4. The scope diagrams in Part 0 and Part 1 have been refined and simplified to more clearly demonstrate the scope of AS 2885.  Combined with defined terms, the delineation between ‘pipeline’ and ‘piping’ is better demonstrated.
  5. With the publication of Parts 0/1/6 in 2018, we recognise that there will be a gap in consistency with the other Parts under revision (Part 2 – Welding, Part 3 – Operations and Maintenance and Part 5 – Pressure Testing), in that some terminology, requirements, content and application may be repeated or in conflict.  But the principles of the AS 2885 suite still stand:  competent personnel applying a safety-based approach to pipeline design, construction and operation.

 

Some detailed information:

  1. “Licensee” is a defined term (as it previously was), referring to the ‘entity held accountable for the pipeline under relevant legislation.  Holding a ‘license’ is not part of the definition, and it isn’t necessarily the owner, and it could be different entities at different points of its lifecycle.  It’s regulatory regime or legislation that determines the ‘entity held accountable’.
  2. The Resistance to Penetration appendix (now Part 1 Appendix E) provides enhanced information and examples for how to determine the pipeline puncture resistance.  There is still ongoing research in this area, in particular around directional drilling, but not yet on augers.
  3. The section on “location classification” is now in Part 6 instead of Part 1, since population density near the pipeline is a fundamental part of risk management.
  4. For pressure testing, Part 5 Appendix P, Test Section Analysis using engineering software or FEA methods, has been copied into Part 1 (Appendix M), and modified/updated.  So that appendix information now appears in two Parts (2018 Part 1 and 2012 Part 5), and they are slightly different.  Test Section Analysis using software (ie, PipeStrain) is a design function, and the principle we’re working towards is that all design activities are covered in Part 1.  The Part 5 Appendix P will be deleted in the 2019 version of Part 5.
  5. The method of applying physical and procedural methods of control for external interference previously required “1 and 2” or “2 and 2” for different location classifications, has been removed.  The requirement now (Section 5.4.4 Design for protection – general requirements) is “all reasonably practicable methods shall be adopted”, followed by a number of should/shall statements about what is required.
  6. The “High Consequence Recognition” statement that was mandatory in the 2017 draft, was modified to be an informative appendix in the 2018 draft.  The 2018 published version of Part 6 states that (Section 1.6.6) “The Licensee shall be aware of the potential consequences of pipeline failures in high consequence areas…”.  The appendix providing guidance on high consequence recognition statement (Appendix H) is referred to a guidance on how to achieve this requirement.  So, it is mandatory that the Licensee shall be aware of potential consequences; how that awareness is achieved is currently up to those responsible to work out (but the Appendix H approach is a good start).
  7. The Part 1 fracture control section (Section 5.3) has been revised, revamped, reworded and redone (several times).  There is an EPCRC research project underway to provide a code of practise in this complex materials science area.  The Part 1 Section 5.3 Fracture Control applies to new pipelines.  Existing pipelines and their fracture control will be addressed in the 2019 version of Part 3.  (This is a case where there is a problem gap between publishing dates).  Stay tuned, stay informed and keep asking questions about this area so that we continue working towards getting it right.

 

And finally, the often-asked question is, ‘when does the new Standard apply’?

The answer is:  it applies once it is published.

(well, maybe it is little more complex and nuanced than that, … but, at this stage, simple is better.)

Standards Status Update – Nov. 2018

Ok, here’s the latest:

AS 2885 Parts 0/1/6
General Requirements / Design and Construction / Pipeline Safety Management

Now anticipating publishing by November 30th.  It will not be on November 21st as currently previously hoped… but, we’re still gunning for a November publish.

AS 2885 Part 2 – Welding

Part 2 Draft for Public Comment is with the Main Committee right now, for approval to go to Public Comment.  All going well there as expected, the Draft will be available in a few weeks.  Therefore the 9-week Public Comment window will extend over the year-end break (ie, November 25 – January 30).  Perfect summer beach reading, right?

AS 2885 Part 3 – Operations and Maintenance

Part 3 has just gone to Standards for its first round of drafting.  The timing for the Part 3 Draft available for Public Comment will depend on the Standards editing process, which could take anywhere from 6 weeks to 6 months.  I’m now guessing an April-ish draft available for Part 3 Draft for Public Comment. But we all know by now that my guessing ability around here is not very reliable.

AS 2885 Part 5 – Pressure Testing

The Part 5 subcommittee has met 3 times in the past 4 months and is making good progress on some tricky technical issues.  Anticipated to be going to Standards for editing by March 2019, and the 9-week Public Comment window starting in May 2019.
