Description |
The project was designed to evaluate, develop, and improve project readiness
of technologies for solutions for the Touch Down Zone (TDZ) region of Steel
Catenary Risers (SCRs) used for deepwater development. There is often
insufficient time during the system selection phase for a project team to
undertake a comprehensive investigation of potential SCR performance and
therefore any selection often later requires timely and costly alterations
to other parts of the system in order to mitigate difficulties with the SCRs.
Furthermore, design improvements during the early stages of development will
lessen the chance of premature failure and any accidental discharge of oil
and gas that may result. This project helped to alleviate those concerns by
evaluating and developing SCR system designs to improve project readiness,
safety and environmental protection at the TDZ region. |
| Progress |
The Joint Industry Project (JIP) researched two case studies with SCR
applications; including 1) a semi-submersible floating production unit in
the Gulf of Mexico and 2) a tanker-based FPSO unit offshore West Africa. The
top four TDZ solutions were be analyzed, developed, and tested/validated
during partial and full scale testing. The four TDZ solutions included 1)
Titanium segment, 2) Lightweight Coating (LWC), 3) Upset pipe, and 4) PDW-1
Integral Connectors. Due to the proprietary nature of the work, the
full-version deliverables will not be releasable to the public for 10 years
following release of the data to JIP participants, estimated in November
2008. Until then, a public-version summary report (Report AA) is provided
below. |
