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
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
