General Requirements 5.1

Production Welding, Welder Performance, Reporting, NDE Tracking, and Pressure Test Verification This information shall be gathered, correlated, linked, reported, and stored in an electronic format (Excel, Access, PDF or similar) acceptable to Saudi Aramco. The contractor's data management and tracking system must be approved by Saudi Aramco prior to the start of work. The data tracking system must meet the minimum requirements of 6.1 and 6.3 below. Note: For limited scope project work, fewer than 500 groove/butt weld joints, contractor may elect to use hardcopy tracking system with the approval of the Saudi Aramco Inspection Department. Reporting for these projects shall use the applicable SATR such as; SATR weld/welder reports: SATR-W-2013 Weekly Welders Reject Rate.xls, SATR-W-2018 Weekly Welder Repair & Tracer-RLCf.xls, SATR-W-2019 Weekly Weld Status Report-RLC-f.xls, SATR-W-2008 Weld Summary Report.xls

5.2

Data Availability The data tracking system(s) shall be maintained and kept current and available for Saudi Aramco's review at all times. The data shall be available on a daily

Page 4 of 12


basis for both current data and cumulative data. Data shall be retrievable by date for any given day from commencement of the work through project completion. At the end of the project the archived records shall be submitted in accordance with contract requirements. 5.3

Data Reporting The Contractor shall track welding activities on a daily basis and submit to Saudi Aramco each week a weld tracking and welder performance report for that week's work. Cut-off date for submitting weekly performance report shall be agreed to by Contractor and Saudi Aramco PQM.

5.4

Output for cumulative weld data and welder data required by this document is to be reported weekly in the weld tracking and welder performance report. Shop and field weld and welder data may be included on the same report.

Production Welding 6.1

Minimum Data Requirements The following minimum data items associated with full penetration groove and butt welds and associated special processes for pressure piping or field-erected pressure vessels and API storage tanks are required to be collected, linked, and maintained for each weld to the extent it is applicable. The acceptance or rejection of groove and butt weld special processes shall be indicated as applicable. When UT is used in lieu of RT the tracking and reporting requirements shall remain the same. Contractor shall record and track production, inspection and testing of socket and fillet welds in a separate database and submit to Saudi Aramco on a weekly basis. DATA ITEM

Progressive confirmation testing

Indicate acceptance or rejection of the required 3 additional HT test on the same weld. If all three (3) retests are below the specified limits, then the joint is acceptable. If any of the retest readings are found to exceed the specified limits, then the weld shall be considered unacceptable.

Weld Identification Numbering System The following weld identification numbering system shall be used to identify and track piping groove and butt welds as a minimum. Weld numbering shall be consecutive in the direction of flow per line. Each weld shall be identified by joint number, line number, and spool number. Physical marking of welds shall comply with the applicable SAES-W specification. In addition to the spool number and line number identification, each weld shall be identified as follows. The example of a first weld is used. W-01

This number has been given to a weld prior to production welding. If required examinations are accepted no change is required.

W-01R1

The W-01 weld has been completed and examination has revealed an unacceptable discontinuity that was repaired. If subsequent examinations are accepted no change is required.

W-01R2

The W-01R1 weld repair has been completed and examination has revealed an unacceptable discontinuity. If subsequent examinations are accepted no change is required. No further

Page 8 of 12


repairs are permitted without express approval of Saudi Aramco. If permitted the suffix R3 shall be used. W-01RW

The unaccepted weld W-01R2 has been cut out and the joint has been rewelded. The identification methodology above is to be applied should further weld repairs be necessary.

W-01T1

The W-01 weld has been completed and examination has revealed

W-01T2

an unacceptable weld discontinuity or HT tests have been rejected. Progressive sampling is required in both cases and the "tracer" welds will be identified. If subsequent tests are accepted no change is required. Repairs on tracer welds will require further sampling in which case the suffix numbering system shall progress accordingly.

Welds fabricated in the field shall be prefixed with the letter 'F' and welds fabricated in a weld shop with the letter 'S'. The above numbering system shall be applied as a minimum for all types of tests and inspections of pipe welds.

6.3

6.2.1

The weld numbering identification system for pressure vessels, tanks, and other pressure-retaining non-pipe welds shall be approved by the Inspection Department Representative prior to the start of work.

6.2.2

Contractors/fabricators may propose alternative numbering systems for approval by PQM. The identification system shall be used to identify all examinations, surveys, inspections, etc.

Pipe welds are to be tracked and reported by line class as follows. Pressure welds other than piping shall be tracked and reported by equipment number as follows. 1)

Number of welds completed

2)

Number of welds subjected to NDT (excluding tracer welds)

3)

Number of welds rejected by each NDT method applied
