Quality Control and Quality Assurance System (QA & QC)
QUALITY CONTROL (QC) SYSTEM
PURPOSE AND SCOPE
The purpose and scope is to define the process control and the methods for verification of compliance with the fabrication and inspection steps set out. Further, to define the control of special processes by demonstration of selected processes. Special processes are the results of process which depends on deep supervision of the process or on the skill of the operator, or on both, in which the specified quality cannot be entirely determined by inspection, or by testing of the work or product.
RESPONSIBILITY
The Project Manager is responsible for provision, preparation, & review the approved/release of the process, control the documents and assign the inspector to inspect, examine and follow the test steps. The supervisor is responsible for the preparation, availability and control the demands of fabrication plan according to the approved/release progress documents and strictly follow the plan and report the progress according to the documents. The shop or site manager is responsible for the adherence of the progress and control the documents during execution and inspection of fabrication process.
SPECIAL PROCESSES
- PROCEDURE AND EQUIPMENT: Special process is executed in accordance with approved/released process controlling documents and are carried out by qualified persons. Process controlling document are prepared, approved and in case confirmed by specialist concerned. The Project Manager shall accept such documents. Maintenance and use of special process equipment is the responsibility of the shop or of the Site Manger.
- WELDING: Qualified personnel shall prepare and approve the technical document for the qualification of the welding process. The welding supervisor shall control the execution, procedure, qualification and shall arrange the participation of other parties concerned (Client or its representative). The welding supervisor shall control the validity of the qualified procedure using the control log. The qualified procedure specification is the basis for the elaboration of the actual weld plan or of a welding instruction by qualified personnel accordingly to written qualified procedure specification. The welding supervisor shall control the qualification of the welding personnel and its verification. The welding supervisor shall be qualified in accordance with the applicable standards and prepare and keep a list of qualified welders and the individual welder certificates, new engaged and replacement welder qualification shall be in accordance with the applicable standards. The welding supervisor is in charge of the welding inspection and any welding related to activity
Prior to start up welding process, the welding supervisor shall control:
- The employment of qualified welders
- The validity of weld plan/welding instruction is in hand
- Released welding materials exactly as specified within the weld plan and welding instruction is available
- The execution and the inspection of welding process shall be documented for compliance with the weld plan/welding instruction, if required.
NON-DESTRUCTIVE EXAMINATION
A non-destructive test (NDT) procedure specification shall be prepared by component NDT personnel and approved by the NDT supervisor, jointly with the Project Manager. The NDT supervisor is responsible for the compliance with the applicable NDT procedure or instruction. The qualification of the NDT supervisor and NDT personnel shall correspond to the applicable project requirements and specifications. The NDT supervisor shall maintain the NDT personnel qualification records. The NDT procedure specification or instruction along with the applicable revision shall be available to the NDT examines. The NDT supervisor shall assess the NDT results.
QUALITY ASSURANCE (QA) SYSTEM
PURPOSE AND SCOPE
The purpose and scope is to define the process control and the methods for verification of compliance with the fabrication and inspection steps set out. Further, to define the control of special processes by demonstration of selected processes. Special processes are the results of process which depends on deep supervision of the process or on the skill of the operator, or on both, in which the specified quality cannot be entirely determined by inspection, or by testing of the work or product.
QA MANUAL
- ELABORATION & DISTRIBUTION: The contractor QA manager assigns the QA systems engineer for the elaboration and distribution of this manual. The QA systems engineer verifies the elaboration by putting his dated signature on each covering page of a chapter, and by activity. Controlled copies of this manual shall be distributed to manual holders. Only controlled copies are permitted to be used by the personnel concerned.
- APPROVAL OF DISTRIBUTION : The contractor QA manager shall approve the distribution and implementation of this document by putting his dated signature at the bottom of the last page of the list of content.
- REVISION: The QA system engineer shall carry revisions to this manual such as updating the instruction to meet the respective changes in the DIN/ISO standards, and administrative changes in the company on behalf of the contractor QA manager.
Changes to this manual shall be performed chapter-wise as follows:
- The revised chapter shall be identified with the actual revision number and date.
- All revision shall be kept in a file.
Each holder of a controlled copy of this Manual shall be notified of changes by Means of the latest List of content, listing revised chapters with the revision and indicating The date of approval of contractor qa manager. A complete set of revised chapters shall be issued to the manual holder. The holder will insert the revised chapters into his controlled manual copy And destroy the superseded chapters.
QA PROCEDURE SPECIFICATION & QA WORKING INSTRUCTION
The general requirements of this manual shall be detailed by QA procedure, specification and QA working instructions. Prior to the distribution, such specifications and instructions are reviewed and approved by the Client or its authorized representative, and the contractor’s QA systems engineer for compliance with this manual.
Such specifications and instructions are status controlled, using logs which shall include the following information:
- Document full identity number.
- Document title.
- Document revision.
- The distribution is controlled using a distribution logbook. The distribution logbook is made out per individual document, including the entire distributor for that document, and the distribution dates to the recipients. For each document a logbook will be retained, in which the recipient name and the date of issuance of the documents to the recipients will be inserted.
All specifications and instructions applying to a certain chapter of this manual are refer to within the last part of that chapter.
This chapter shall be supplemented by the QA working instructions as per the Project requirement.
