Traceability and documentation is required Documentation
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 • 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
