1.0 PURPOSE AND SCOPE 1.1 PURPOSE

The purpose of this document is to define the system to be followed for the management of any changes for the Tangguh Gas Production Facilities (GPF) Project.

1.2 SCOPE

This procedure covers change to the agreed scope of work, irrespective of the source of the change requirement, and all technical changes which change the intent of the agreed design basis criteria (i.e. COMPANY Statement of Requirements (SOR), Basis of Design documents / Design Philosophies, Safety Case, Criticality Assessment, Material Changes and any Regulatory requirements). The procedure shall also apply where there are any changes estimated to have an impact to Cost or Schedule. Examples of the source of change include (but are not limited to): ?? Change to design deliverables which change the design basis intent ?? Instructions from COMPANY to CONTRACTOR ?? Changes arising from Technical Queries / Technical Notes, Site Queries or Field

Design Changes. ?? Supplier or CONTRACTOR deviations or concessions (Concession Request) ?? Fabrication changes ?? Construction and Construction Methodology Note: In addition to this change control process, CONTRACTOR(s) shall be expected to operate suitable change control procedures for their documents. This requires the maintenance of 'Master documents' upon which changes are noted (in between the document update and re-issue) and communicated to other disciplines / parties that may be impacted by the change. Any site changes shall be recorded by either the Technical Query / Technical Notes Procedure, document number 9000-PRC-EM-0004 and / or Field Design Change Procedure, document number 9000-PRC-EM-0007 and any concessions shall be handled in accordance with Concession Request Specification, document number 9000-PRC-EM-0005.
