Standard Sub-Sea and Special Deep-Water Connections
Standard Offshore Operations
As with on-shore operations, sub-sea maintenance procedures can be accomplished without interrupting product flow. TDW has performed tapping and line plugging services for platform and subsea projects around the world. In fact, our service technicians performed the first underwater STOPPLE® Plugging job in the Gulf of Mexico. Standard applications include Sub-sea 1000 Tapping Service with taps from 6" to 16", at pressures up to 2,200 psi, and the capacity to work at depths down to 1,000 feet. More demanding sub-sea taps to 36", at 1,480 psi, are also available from TDW Services.

Gulf of Mexico, Crude Oil Tie-In
TDW Services was contracted to join a 16" sub-sea crude oil transmission line with a 24" line. The 16" line would be tied into the larger line and the remaining 16" line purged and abandoned. TDW Services technicians used a Model 1200 Sub-Sea Tapping Machine to make the 16" taps required to tie the lines together. A STOPPLE® Plugging Machine isolated the section to be removed. TDW's specialized sub-sea equipment ensured reliable operation. The finest equipment, combined with our experienced, Certified Technicians are your keys to success in the harsh, unforgiving sub-sea environment!
Special Deep Water
To meet the huge challenges of performing deep-water hot taps at depths beyond 1,000 feet, TDW has entered into an alliance with Williams Energy Services, Oil States HydroTech Systems Inc. and Oceaneering International, Inc. The equipment and procedures being developed, called "Deep Tapp Technology," will utilize remotely operated sub-sea vehicles to connect gathering lines to transmission pipelines in water depths up to 10,000 feet. The new technology can be applied to lateral tie-ins up to 20" in diameter and ASME class 1500. This amazing deep-water technology will become yet another first for TDW. |
