1.0 INTRODUCTION
1.1
Project Description
The Greater Enfield Development is a proposed greenfield development located to the west
of Company’s existing Enfield and Vincent assets as shown in Figure 1.
Figure 1-1 - Laverda Geographical Location
The Development will exploit 3 oil accumulations and is shown in :



Norton-over-Laverda (NoL)
Laverda Canyon (LC) and;
Cimatti
The full subsea system includes a total of 14 wells, 12 of which are included in the first phase
which is the subject of this Scope. These are as follows:



7 production wells
5 oil wells and 1 gas well in the Laverda area
1 oil well at Cimatti
The gas well is a future well. Provision for it is included in the base scope, but the tree will not
be installed or commissioned as part of the first phase of the Greater Enfield Development
which is covered by this Scope.
The production wells are tied back to the Ngujima-Yin FPSO via a 16” OD wet insulated carbon
steel flowline and a 10” ID flexible production riser.
There are 6 water injection (WI) wells: 3 are for pressure support of Laverda Canyon, 3 are
for Cimatti. They provide low salinity injection water from the FPSO via a 10” OD carbon steel
flowline and a 10” ID flexible riser.

APPENDIX B ADDITIONAL CONTRACTOR
REQUIREMENTS
B.1
Manufacturing Data
All forgings shall be in accordance with ASTM A694M and COMPANY supplied specifications
referenced in Section 4.0. The Vendor shall have relevant experience with the metallurgical
aspects of the forged steel grades and designations including weldability and heat treatment
applications and parameters etc. as applicable, for his manufacturing processes.
Experience shall be supported by statistical data or test records, as relevant, for the size range
and grade to be qualified.
The steel shall have been produced in accordance with CONTRACTOR approved Vendor’s
manufacturing procedures specification (MPS) and with the same equipment and process
route intended to be used for the actual manufacturing of the production forgings. Facilities
and equipment shall be suitable for the purpose of producing the steel forgings and grades as
specified herein and shall be regularly maintained and calibrated as required by consensus
industrial standards.
If part of the work is sub-contracted, the Vendor is fully responsible for making sure that the
sub-contractors meet the same standards and capabilities for the manufacturing process step
as for the Vendor.
The manufacturing process including all heat treatments shall be qualified by physical testing
of the actual product.
Only companies with proven experience of similar application, in particular in regards to
documented weldability of the forged steels, shall be used.
Vendor shall submit:


List of all sub-contractors from steel making through to finished forging.
A complete manufacturing procedure covering all steps from steel making through to
finished forging.
Prior to the manufacture of any forgings, i.e. steel making, Vendor shall submit to
CONTRACTOR for approval, a detailed MPS incorporating all the requirements of this
specification, as well as the requirements of any referenced code and standard. This
document shall describe the procedures to be followed by the Vendor during the manufacture
of the forgings. The procedure shall be submitted immediately after the placement of the
purchase order and prior to any kick-off / pre-production meetings.
The manufacturing procedure shall contain, as a minimum, the following information, but not
limited to:



Material data (Chemical composition with allowable ranges, steel grade etc.)
Steel making and refining processes
Forging procedure (Forging equipment, hot work temperature, forging reduction
ratio, etc.)

NDE
a.
UT of Forgings
All forging shall receive UT in accordance with ASTM A388, SAE AMS-STD-2154, ASTM
E2375 or DNV-OS-F101 Appendix D, Part D prior to shipment from the forging facility.
Volumetric coverage shall be 100 percent with straight-beam from three mutually orthogonal
directions whenever practicable. When scanning with straight-beam from three mutually
orthogonal directions is not practicable, angle-beam may be utilized to effect 100 percent
volumetric coverage.
UT procedures, calibration procedure and scan plans shall be approved by CONTRATOR.
UT acceptance criteria shall be in accordance with SAE AMS-STD-2154 or ASTM E2375
Ultrasonic Class B. Flaws interpreted as cracks or flakes shall be rejected regardless of size.
If UT is performed prior to quality heat treatment, then another UT shall be performed after
quality heat treatment. Additional criteria for UT acceptance shall be sought from COMPANY
documents specified in Section 4.0.
Reference is required regarding NDE operator certification.
b.
MT of Finished Surfaces
All forging shall be examined by wet-fluorescent MT in accordance with MIL-STD-1907, ASTM
E1444 or DNV-OS-F101 Appendix D, Part D. DC magnetizing prods shall not be allowed.
Final MT shall be carried out after final heat treatment, including stress relieving, and
machining.
Surface coverage shall be 100 percent of finish-machined surfaces with magnetization in at
least two mutually perpendicular directions (circumferential and longitudinal for hollow
cylinders or tubulars).
MT procedures, calibration procedures and scanning plans shall be approved by
CONTRATOR.
Remnant-magnetic-field strength (residual magnetism) shall not exceed 15-gauss (750 A/m)
(or 30-60 gauss for Hall-effect gaussmeter) subsequent to MT.

PIPELINE FORGING DATASHEETS
Acceptance criteria shall be in accordance with MIL-STD-1907 Grade A, ASTM E1444 or as
otherwise specified in the purchase order or CONTRATOR standards and documents
specified in Section 4.0.
c.
VT
All forgings shall receive VT after final heat treatment in compliance with ASME BPVC-V
Article 9. Additionally, a written procedure shall be produced by the Vendor that complies with
ASME BPVC-V Article 9 Para. T-921 and approved by the CONTRACTOR.
All forgings shall receive VT with 100 percent surface coverage of all accessible surfaces to
be free from visible laps, cold shuts, cracks, porosity, slag, excessive scale, and other surface
imperfections. Additional criteria for VT acceptance shall be sought from CONTRATOR
documents specified in Section 4.0.
Additional requirements shall be sought from or DNV-OS-F101 Appendix D, Part D. The
results of all NDT shall be reported in the documentation package for forging.
d.
NDE Operators Qualification
All personnel conducting and evaluating NDE on forgings manufactured in accordance with
the requirements of this specification shall be qualified and certified to Level II of ASNT-SNTTC-IA, or CONTRACTOR approved equivalent, with documented experience on forged steel
products for at least 6 months, of which, shall have been at Level II.
A Level III technician or equivalent shall be responsible for all NDE including development of
Vendor’s NDE procedures and interpretations of indications and defects.
Visual and magnetic particle inspection shall be carried out by qualified inspectors/operators
who have passed the Jaeger No. 2 eyesight test within the past 12 months. A list of proposed
technicians and their qualifications shall be supplied prior to production for CONTRACTOR
review.
Additional requirements shall be sought from or DNV-OS-F101 Appendix D, Part D.
B.4
Documentation
Unless specifically deleted/waived by the RFQ, PO or applicable Vendor specifications, an
additional copy of the documentation package shall be sent to CONTRACTOR. Vendor shall
compile a manufacturing record book (MRB) containing information on all aspects of the
processing of the forging and final supply. It shall contain, as minimum:







Material certification including heat treatment records
Qualification test results
NDE records and certificates
Mechanical test results
