1 SCOPE

Contractor proposes this Project Material Criticality Assessment Plan to define the minimum requirements of Supplier’ Surveillance to be carried out on the equipment and materials to be supplied by Contractor for the Project.

2 REFERENCES

Contractor shall carry out an adequate Supplier Surveillance activities according to the requirements included in the relevant Requisition and the level code due to the Quality Class (CQ) therein mentioned. The Quality Class of each material is considered equal to the Criticality Rating, which shall be calculated according to the indication of present Plan, after OWNER/IPMT approval. The Criticality Rating calculation results, for all items, shall be recorded by means of the forms attached in Attach. 1. The Commodity Criticality Rating (table 3) is achieved through the combination of the assessment of the Criticality Impact (table 1) and the evaluation of the Commodity Complexity (table 2). The evaluation is carried out in the course of a dedicated meeting, leaded by the Project Engineering Manager and with the participation of:

• Process Manager • Technology Manager • Safety Engineer • Disciplines Engineer • Welding Engineer • Procurement Manager • Inspection Manager

The Project Engineering Manager is nominated facilitator to timely call and conduct the meetings, to ensure the adoption of common criteria. Proposals issue are mainly from:

• Process Manager, for major process equipment indicated in the Equipment List • Design Department, for the other components, whenever the assignment of a

class other than the default class is deemed useful. The expected duration I 1 day for each typology of Plant. OWNER/IPMT will be informed of the date and venue of the meetings to have the possibility to attend the meetings.

The material conformity is established through Supplier’s certificate review. The Contractor's Inspectors follow the relevant operating mode described in paragraph 5. Desk expediting by phone, every 3 weeks. Expediting visit to be fixed if necessary. Inspection & Test Plan (ITP) and test procedures not required, Supplier standard documents applicable.

4.2 Code “CQ3”

This code denotes equipment and/or materials having medium technological content or complexity. The Contractor’s Inspector witnesses the functional and/or final test as per indicated requirements, following the relevant operating mode described in paragraph 5. Desk expediting are performed every 2 weeks while expediting visit are performed at least every 4 weeks. ITP required, test procedures not required, Supplier standard documents applicable.

4.3 Code “CQ2”

This code denotes equipment and/or materials having high technological content. The Contractor’s Inspector surveillance is scheduled on regular basis, at least every three weeks, the inspector witnesses intermediate, final test during fabrication phases, adopting the relevant operating mode described in paragraph 5. Surveillance inspection frequency could be increased only case by case, after analysis of the elements that could affect the correct supply of the item. Expediting visits to be performed at least every 2/3 weeks. Intermediate desk expediting to be performed if necessary. ITP to be approved during the pre inspection meeting by Contractor and OWNER/IPMT representative, Supplier procedures for fabrication and test required.

4.4 Code “CQ1”

This code denotes items having high construction complexity, where any non-conformity may affect the objectives of the Project, and a relatively high technological content. The Contractor’s Inspector surveillance is scheduled on regular basis, at least every fortnight, the inspector witnesses the fabrication phases, intermediate and final tests, following the relevant operating mode described in paragraph 5. Surveillance inspection frequency could be increased to daily or weekly only case by case, after analysis of the elements that could affect the correct supply of the item. Expediting visits to be performed on regular basis every fortnight, frequency could be increased, depending on supply performance results. Intermediate desk expediting to be performed if necessary. ITP to be approved during the pre inspection meeting by Contractor and OWNER/IPMT representative, Supplier procedures for fabrication and test required.
