Scope:
- J. Ray McDermott responsible for fabricating, transporting
and installing a 4-pile platform and transporting &
installing Garden Banks 388 subsea template and associated
pipeline system on a fast-track schedule.
Technology:
- Deepwater S-Lay
- Deepwater Lowering System
- Rigid Jumper Spools
|
Description:
- The 1,280 ton template was installed in 2,100 ft. water depth
(almost a half mile). The shallow water processing platform was
fabricated and installed in Eugene Island Block 315. The subsea
template and floating production system (FPS) in the deepwater
at Garden Banks 388 was tied by pipelines to the shallow water
facility in 245 feet of water some 54 miles away. Sales pipelines
were installed to transport product from the shallow water facility
to transmission lines.
Innovations:
At time of installation, the following records were established:
- Deepest conventionally S-laid pipelines
- Largest, deepest template installed in the Gulf of Mexico
- Deepest known use of ERW pipe
- Deepest rigid jumpers
- First use of “Rough” FBE Coating
