Time-Saving Wellheads
Pressure Control OSH Oshore Speedhead
™
System
The OSH Oshore Speedhead™ System is specically
designed to be compatible with the drilling methods
commonly used in the Gulf of Mexico. It has a two-stage
starting head, combining the casing head and casing spool
into a single housing. The diverter or BOP stack is made up
to the starting head before drilling commences and is not
removed until two strings of casing have been run.
This technique impacts both rig costs and safety. By landing
two casing strings in one compact forged housing, the OSH
system eliminates one complete BOP nipple-down/nipple-
up thereby saving signicant rig time. By reducing handling
of wellhead and BOP equipment and minimizing potential
wellhead leak paths, the OSH system substantially improves
safety.
When combined with the SH2 split speedhead system, this
package can save from 24 to 40 hours of valuable rig time.
