Tender Number [9900009229] Supply of Services for Detailed OEB Crude Assay Analysis SCOPE OF WORK
SCOPE OF WORK 1. Introduction Orpic is the brand name for Oman Oil Refineries and Petroleum Industries Company SAOC. Orpic operates a 106 KBPSD hydro-skimming refinery at Mina-Al- Fahal (MAF) and a 116 KBPSD cracking Refinery with downstream Aromatics and Polypropylene plant at Sohar. Feedstock for both the refining complex is Oman Export Crude Blend (OEB) supplied by PDO from Mina Al Fahal. For the purpose of Refinery business planning, Orpic now intends to carry out detailed OEB crude assay analysis. 2. Scope of Services Sample to be tested by bidder for complete crude characterization. The specific properties to be analyzed for the various product cuts are as listed in the Appendix A-J 3. Minimum Technical Requirements Laboratory shall be ISO 9001-2008 certified. Laboratory shall be accredited to ISO 17025 International standard methods like ASTM (American standard Testing Materials) to be followed for testing 4. Facilities to be provided by Contractor Sample containers and Auto Sampler Kit to be provided by the bidder to Orpic laboratory in advance Or Assign manpower to collect the sample at a predetermined time and frequency Samples to be collected from Orpic Laboratory (MAF Refinery, Mina Al Fahal, Muscat) by the bidder. 5. Facilities Provided by Orpic Orpic will arrange for the required gate passes and other facility access requirements for the bidder personnel to collect and take away the sample. 6. Reporting Requirements Bidder to submit a full test report within 28 days time from the day of collecting the samples either by mail or hard copy. One page (A3 Size) Summary report including all the product cuts along with yields and other properties to be submitted.
The report shall be submitted both in print (.pdf) and editable (.xls) format.
