 Approach
Benefits
 Shell UK Exploration and Production required new water injection facilities
to enhance production at the Pierce Field, located in the North Sea. The Pierce
field was brought on-line in 1998 via two manifolds on the seabed. The new water
injection system will provide treated water to the existing drill sites via
a new 10” water injection riser from the FPSO Haewene Brim to a riser
base. A flowline then feeds each drillsite.
MCS provided expertise to Shell in a number of areas, including FEED study
to determine critical areas related to the riser design and also verification
of the final flexible riser design performed by Technip.
|
- Perform a feasibility assessment of possible flexible
riser configurations.
- Perform a FEED study to determine realistic riser
hang-off loads for design of the hang-off arrangement to the APL submerged
turret mounted buoy. This would allow long-lead items to be designed
and procured for the project prior to detailed design.
- Provide independent flexible pipe expertise during
the EPIC bid review.
- Perform independent verification concurrent with
the design of the Technip flexible riser. Verification areas included
pipe cross-section analysis, riser extreme response and riser service
life analysis. .
- Ongoing assistance to Shell with various flexible
pipe issues throughout the duration of the project.

|
- Using our extensive flexible pipe knowledge, we
provided ongoing expertise to Shell on various issues related to the
design of the riser and flowlines at all stages of the project.
- Our approach to the FEED study allowed early identification
of critical areas of the design that were subsequently highlighted
to the EPIC contractor for detailed design.
- Through close involvement with the EPIC contractor,
we performed a detailed independent verification in parallel with
the Technip detailed design phase. This ensured any critical areas
were fully examined prior to manufacture and installation.
- Our involvement from the FEED study through to
design verification provided Shell with the benefit of flexible pipe
know-how from a worldwide independent expert in flexible pipe technology.
