Documentation Traceability and documentation is required
Documentation What is traceability ? The formal definition: Traceability is the ability to chronologically interrelate uniquely identifiable entities in a way that is verifiable. Traceability is the ability to verify the history, location, or application of an item by means of documented recorded identification.
Traceability What does this mean ? ? The practical implementation of traceability will often vary according the product/application For off-shore fabricators the implementation will be more comprehensive than for ex shipbuilding
Traceability From NORSOK M-601: : : The WPQR/PQR documentation shall include the material certificates for the base and filler materials applied in the weld qualification test. All welding and related activities shall comply with the requirements of ISO 3834 -2 and the additional requirements of this NORSOK standard.
Traceability All welds should be identified by unique numbers. The shop drawings shall contain enough information to enable correct selection of WPS. Minimum information needed is • material type/grade and grouping number (ISO/TR 15608), • dimension (outside diameter and wall thickness), • PWHT requirement.
Traceability All welds should be identified by unique numbers. All pipes, fittings and welding consumables should be colour coded according to Annex D. All welding consumables shall have individual marking.
Traceability From NORSOK M-101: : The fabricator shall apply a weld numbering system for identification on all shop drawings and as reference in all documentation. Welding shall be carried out in accordance with the WPS and applicable drawings.
Traceability The inspection category shall be decided by the designer in accordance with NORSOK N-004, and shall be specified on the design drawings.
Traceability Requires that a system for identification has been implemented BUT--- that means that the identification must be maintained through the production process
Traceability Ex. PLATE Plate is documented through a Material Certificate However that plate comes from a Batch no Produced at one Furnace at a given factory When the plate is cut-- the all parts has to be traced back to the plate And the remaining plate to be identified
Traceability Then we need to know where the parts have been used in the construction We have to know which weld numbers are joining the parts And we need to know which WPS has been used for each of the welds
Traceability We need to know which welder(s) was welding that weld We need to know when it was welded We need to know the result of the inspection beiing carrried out
Documentation In order to fullfill the traceability we have to create a proper documentation that we can use as a proof of our work. We can create the documentation in two different ways
Documentation A. Positive documentation--- that means we create documents for everything we are doing in form of reports That means if the inspection is OK we make a report saying that the results is OK
Documentation B. Negative documentation-- that means we create reports in form of documents only when the findings are NOT OK. For findings that are positive, or OK, we sign off that the finding was ok and that it has been carried out according a standard procedure specified in detail by the company
Documentation is vital for establishing a good relationship with the customer Documentation should be followed up so that the required documentation can be delivered together with the product delivery
