Log book of the operational control of assembly and welding operations in the construction of a vertical cylindrical tank. ANNEX 3.

EXPLANATION TO THE DESIGN OF THE JOURNAL OF POOPERATIVE MONITORING OF WELDING

AND WELDING WORKS

  1. The Log book of the operational control of assembly and welding works is a document that determines the scope and sequence of the main control operations during the installation works intended for operational control and clearance of delivery and acceptance by the contractor and owner representatives for each tank at the construction site.

  2. This document establishes the personal responsibility of the contractor's and owner's officials for the operational delivery and acceptance of construction and installation works. The representative of the contractor is responsible for the timely conduct and correct registration of the Log book, as well as the delivery documents attached to it. The Log book of operational control is conducted by a foreman (master), appointed by order on organization. Control over the correctness of conduct and registration of the log book and delivery documentation is assigned to the owner's representative (technical supervision).

  3. All entries in the log book must be made in ink and legible. Mopping is not allowed. Corrections must be agreed and certified by the signatures of the representative of the contractor and the owner.

4.Before the start of the installation work, the list of persons admitted to the delivery and acceptance of work (Section 1) is filled in and this section is certified by the signatures of the contractor's and owner's managers.

5. Before the beginning of welding operations, based on the verification of certificates or certified copies of welders' certificates, the list of welders is filled in (Section 2). Column 5 section2 is filled after obtaining a positive conclusion about tests of control samples (admission joints) welded by a welder. Correctness of the filling of column 5 for each welder must be certified by the signatures of the head of the site of the assembly organization and the Owner's representative in column 6 and 7 respectively.

6. Acceptance of the foundation for the erection of metal structures is carried out by the commission under the act, the name, the number and date of which is entered in section 3 of this log book. One copy of the certificate, transferred to the assembly organization, is attached to the journal of operational control. The act in the application is certified by the signatures of the representatives of the contractor and the customer in column 3 and 4, respectively.

7Acceptance of metal structures, equipment in the installation, supplied by the owner, is carried out on the basis of a request for issuance of materials (material issue request), acts of entry control with the entry of entries in section 3, column 3 and the Acceptance and Delivery certificates of the inventory. One copy of the certificate is attached to the journal. The presence of an act in the annex is certified by the signatures of the representatives of the contractor and the Owner in column 4 and 5 respectively.

8. Section 5 records the names, numbers, dates of documents for which the technical documentation was obtained by the installation organization with the signatures of the representatives of the contractor and the owner.

9. The operational control and acceptance of the installation work is carried out in accordance with the requirements of Section 6 and control measurement schemes for installation. The responsible executor of works with his signature in column 9 fixes the execution of each operation. The representative of the customer fixes the execution of each operation in column 10.

10. Control and acceptance of welding operations is carried out in accordance with section 7 and control schemes. The evaluation of the quality of each weld is recorded in column 6.

11. The operations in Sections 6 and 7 are subject to activation. Registration of acceptance of the executed works should be made in time, i.е. after the control of each operation. Section 8 records the defects identified during the inspection and acceptance of installation works, the elimination of which is associated with the adoption of a technical solution. All deviations from the design, installation and technological and regulatory documentation, made during the execution of works, are entered in section 9.

12Changes to the operational control log are made based on the "Notice of Change" from the representative of the installation company. The registration of the changes in the operational control of changes is registered in the registration of changes.

13. The completion of the installation works is formalized by the act of commissioning the reservoir, in which the head of the Owner's organization gives a conclusion on the performance of the installation work in full in accordance with the requirements of the design, installation and technological documentation, acceptance by the owner's representative and the readiness of the reservoir for commissioning.
