PREFACE Woodside Energy Ltd. (WEL) has developed a suite of Engineering and Technical Standards and Guidelines. It is intended that these reflect the most suitable engineering practices for use on all new WEL facilities as well as the modification of existing facilities. The application of the Standards is mandatory. The application of Guidelines is to support the implementation of the Standards, and are considered best practice, but are not mandatory.

The Standards are based on the experience acquired by WEL personnel and contractors during WEL’s involvement with the design, construction, operation and maintenance of WEL processing units and facilities. Where appropriate, the Standards are based on or make reference to national and international standards and codes of practice.

The objective of this publication is to ensure the overall integrity of engineering design and to achieve maximum technical and economic benefits through the standardisation of engineering and technical practices.

The use by WEL contractors or manufacturers/suppliers of the Engineering and Technical Standards contained in this publication does not relieve them of any responsibility whatsoever for the quality of design, materials and workmanship that they have been engaged to provide.

Where the standards to be used for a certain application are not provided for in this publication, WEL expects that the standards that are used will achieve the same level of integrity as reflected in this publication. If WEL contractors or manufacturers/suppliers have any doubt as to the relevant standard to use, then they must consult WEL, however they will remain responsible at all times for the use of the most appropriate standard. Specific requirements may be added as an addendum to these Standards and Guidelines for various projects. Project specific requirements must not depart from the requirements of the Engineering and Technical Standards contained in this publication. Where changes or additions to these Standards are required, they must be raised as a deviation and presented to the WEL Technical Authority for consideration.

WEL grants the right to use these Standards and Guidelines to WEL’s consultants, contractors and suppliers who are contractually authorised to do so and to any tier of contractor to its consultants, contractors and suppliers who are contractually required to comply with them.

DISCLAIMER WEL and its joint venture partners disclaim any liability of whatsoever nature for any damage (including injury or death) suffered by any company or person whomsoever as a result of or in connection with the use, application or implementation of any standard, combination of standards or any part thereof contained in this publication.

1 INTRODUCTION 1.1 Scope This Technical Specification contains the minimum technical specifications for Centrifugal Pumps. It replaces DEP 31.29.02.30-Gen. should there be any references.

This Technical Specification is based on API Standard 610, Tenth Edition, October 2004 / ISO 13709, 2003. This specification amends, supplements, and deletes various clauses/paragraphs of API Standard 610. Clauses of API Standard 610 that are not mentioned in this specification remain applicable as written. This specification shall be used in conjunction with the data/requisition sheet relevant to the equipment it serves. Equipment covered by this Technical Specification shall comply with API 610, as amended and supplemented by this Technical Specification

This Specification is specifically made and intended for use in the Woodside Expansion Projects. As such its contents are supported and endorsed by the Principal for this job specific purpose only. Under no circumstances, whatsoever, shall this document be used or considered as a general replacement of DEP 31.29.02.30-Gen outside the scope of this project.

• Regulatory Considerations If international and/or regional regulations exist in which some of the requirements may be more stringent than in this Standard an assessment shall be made to determine which of the requirements are the more stringent and which combination of requirements will be acceptable as regards safety, environmental, economic and legal aspects. In all cases the Contractor shall inform the WEL Technical Authority.

• Definitions The definitions below shall apply:

• The Contractor is the party that carries out all or part of the design, engineering, procurement, construction, commissioning or management of a project, or operation or maintenance of a facility. The Principal may undertake all or part of the duties of the Contractor.

• The Manufacturer/Supplier is the party that manufactures or supplies equipment and services to perform the duties specified by the Contractor.

• The Principal is the party that initiates the project and ultimately pays for its design and construction. The Principal will generally specify the technical requirements. The Principal may also include an agent or consultant authorised to act for, and on behalf of, the Principal.

• The words shall / must / will indicate a mandatory requirement.

• The word should indicates a recommended course of action.

• The words may / can indicate one acceptable course of action.

• WEL Technical Authority (TA) in this document refers to the Mechanical TA. Authority to deviate from these standards is delegated to the custodian(s) indicated on the document details page of this document.

1.2 Action Items A round bullet in the margin next to a clause in API 610 indicates either that alternative requirements are possible and a decision by the Purchaser is required or that further information is to be provided by the Purchaser. This decision/information shall be indicated in the space





provided on the data/requisition sheet. In some cases these decisions have already been made by the amendment to the API clause in this specification, effectively eliminating the bullet. In other cases this specification is silent and the Purchaser remains responsible for making the decision or providing the required information. In some of these latter situations this specification considers that the Purchaser should remain silent since the option available is not normally required or recommended. A summary of the category into which the bullets fall is shown in Table 1 below (referring to the bulleted paragraph numbers in API 610):
