1. Purpose
The purpose of this Local Work Instruction is to carry out uniform review of supplier’s welding
documents by Materials Engineers and Welding Engineers. It is developed to secure that supplier
receive the same codes and comments for the same documents if requirements are the same. All
personnel in the material department should have the same interpretation of specs, standards
and regulations. When necessary, interpretation shall be clarified with a Chief Engineer and shall
be registered and distributed.
2. Scope
The document is intended for use by Materials Engineers and Welding Engineers while reviewing
Welding Procedure Specifications and Welding Books. Instruction contains checklists for review
based on international/national standards, FMC specifications, customers’ specifications.
3. References

SPC60XXXXXX Specifications for welding, NDE and other processes that include some/all
requirements, e.g. SPC60083562, SPC60087381, SPC60091356, etc.

WDS-0000014 Welding specification for type UNS NO6625 weld metal overlay
WDS-0000015 Welding data sheet, welding and inspection of small bore tubing and
related components
Weld Plan – a document or drawing also known as "weld map" that is indentifying WPS
and inspection/NDE requirements for each individual weld.
Welding Book – a document that contains all related WPSs and WPQRs for the given
part. It may contain weld plan.
Supplier Master Document Register (SMDR) – an agreement between the supplier and
FMC Technologies on what documents the supplier shall submit for review.
It is the WPS that will be reviewed; WPQRs are supporting documents and will not get a separate
approval code, but will be referred to in the DR4 form. Technical requirements in standards,
specs and regulations should be fulfilled as far as possible. If this is not possible engineering
judgment shall be used. The criticality of the Product must be considered in such cases. ON
HOLD: Typical welds with high criticality are pressure containing welds, fatigue sensitive welds,
cladding, welds of high load structural components. Other structural welds (e.g. ROV basket)
have lower criticality. This is also reflected in the design class and steel quality level.
6
Review of WPS is documented in DR4 form for material department, each WPS and Project.
Example of DR4 is to be found in Appendix C.
ON HOLD: code 2 to be deleted? Code "2" means minor comments in terms of clarifications
according to spec requirements. Code “2” comments shall always refer to specific requirements
(code or project)!
Code "2x" is an information to supplier that FMC have no comments, but client will also review
the document. Start of production is at supplier’s risk. Some projects do not approve the use of
code "2x". To be checked with project prior to review.
Code "3" means "STOP" and should be used only when the technical content is such that it is not
advisable to fabricate - Finn disagree. In these matters direct communication between FMC
Materials Engineer and supplier is needed to clarify and agree upon alternative and acceptable
solutions. Code “3” comments shall always refer to specific requirements (code or project)!
Finn: if deemed necessary by the reviewer code 3 can be used to ensure implementation of
comments before start of welding.
!! NOTE: under no circumstances can the DR4 review be used in lieu of a deviation /
concession request. In cases where a deviation / concession request has been handled in
the QN system it can be referred to in the DR4
5.3. Checklist
In general the following information is to be checked while reviewing WPS:
II. WPQR front page content (shall be stamped / signed by an examiner (third party)
III. Extent of destructive and NDE testing and test results: reports attached to WPQR (shall
be stamped / signed by an examiner (third party))
Welding Procedure Specification and WPQRs content shall be prepared in accordance with ISO
15614-1 (-5/ -7/ -11) (see example of WPS in Appendix E) or ASME IX (see example of WPS in
Appendix F).
Requirements for essential variables and acceptance range shall be checked in accordance with
the following standards:
For piping systems: ASME IX / Norsok M-601 and ISO 15614 + customer specs
For structural welds: Norsok M-101 and ISO 15614 or AWS D1.1 + customer specs
ISO 15614, Norsok M-601, Norsok M-101 and AWS D1.1 contain essential and nonessential
variables. ASME IX also defines supplementary essential variables.
Essential variables are conditions in which a change, as described in the specific variables, is
considered to affect the mechanical properties of the joint. Before using a procedure specification
whose essential variables have been revised and fall outside their qualified range, the procedure
specification must be re-qualified.
Supplementary essential variables are conditions in which a change will affect the toughness
properties of the joint, heat-affected zone, or base material. Supplementary essential variables
become additional essential variables in situations where procedure qualifications require
toughness testing. When procedure qualification does not require the addition of toughness
testing, supplementary essential variables are not applicable.
Nonessential variables are conditions in which a change, as described in the specific variables,
is not considered to affect the mechanical properties of the joint. A procedure specification may
be editorially revised to change a nonessential variable to fall outside of its previously listed
range, but does not require requalification of the procedure specification.
Additional requirements are listed in FMC specifications and Customer specifications. References
to these specifications are to be found in Material Selection and Corrosion Protection Philosophy
for the project.
Testing includes both non-destructive (NDT) and destructive testing which shall be in accordance
with the requirements of relevant standard and client specs.
Impact test: test temperature shall be in compliance with project minimum design temperature
requirements / spec requirements.
Chemical composition, mechanical properties, microstructure (if applicable), ferrite counting (if
applicable), corrosion test (if applicable) shall be checked according to international standards /
FMC material specs / customer specs. Reference code requirement (NORSOK, ASME IX, etc)
shall be stated.
Only material certificates type 3.1 and 3.2 according to BS EN 10204 are acceptable.
”Third party”
Content of DR4 of previous reviewers for given WPS is to be checked prior to issue of a
new DR-4.
In cases where previous reviews are made incorrect the consequences on previous PO’s
must be evaluated and, based on criticality, QN shall be issued.

Appendix C. DR4 in SAP
Document center for each Project receives the WPS/WPQR from supplier and register into SAP
and E-Plan before forwarding the documents for review to the Materials department. Materials
department review WPS, give a code and link the supplier document to the DR4 form. If WPS is
in code 1 or 4 the supplier document itself shall be released in SAP. Documents in code 2 or 3
shall be updated to VC status.
When code 2 or 3 is given to WPS, reference to standard / spec requirement that WPS is
deviating from shall be made for each comment. Exact date to be stated in “Due” field, not
“ASAP”. Revision of standard / spec to be stated in “requirement specification” field.
Proposal: DR4 revision number + date + reviewer’s initials to be stated under the “subcontractor
documentation” table to keep history of review. Example: DR4 rev. 0, 29.04.11, SB.
