1 INTRODUCTION

1.1 PURPOSE AND OBJECTIVES

Specifications (SP) contain information/requirements on PDO facilities that are either usedrepeatedly, or that are retained for future reference. These documents are intended for useby the Company and its nominated Consultants and Contractors. It is the responsibility of theUser to ensure that he is using latest revision of this specification

The SP system is intended to:

Publish guidelines or codes of practice.Set the Company standards.Form a basis of technical specifications for the procurement of equipment or technicalservices.Disseminate and record engineering information, experience and procedures.

This Document is fully restricted for PDO. The accessibility for this document shall bemaintained by PDO Mechanical Corporate Functional Discipline Head (CFDH) and histechnical focal point.

This specification together with standard drawings, SPs, DEPs as mentioned in section 2sets out the minimum requirements for the design, engineering, supply of materials,fabrication, assembly, inspection, testing, transportation, installation, commissioningsupervision, functionality and supply of Pressure Vessel package. It has been written in aformat that enables the Project engineer and the Consultant to easily and uniformly prepare arequisition and purchase Pressure Vessels, storage (atmospheric) vessels, pressure parts offilters, shell & tube heat exchangers etc. for a variety of applications in PDO.

For a specific purchase the Project Engineer / Consultant shall:

Follow this specification in general and do not require to produce additional specification. Butin case of any project or equipment specific requirements, which are different from the onesspecified in this specification, shall be prepared and attached as an amendment/addition tothe particular sections of this specification.

Ensure that the Vendor receives the applicable documentation listed in subsections 2.1, 2.2,2.3 & 2.5.

Ensure that procedures for Vendor Drawings/Documentation are in accordance withSP-2047 'Preparation and Content of Engineering Drawings' and Section 7 of thisspecification.

This specification shall be used in conjunction with relevant equipment data sheets in theDEP format attached in Appendix-2 and Environmental & Site Conditions attached in

Appendix-1. The User shall complete/follow these data sheets as applicable.

1.2 CHANGES TO THE SPECIFICATION
