A drillship has greater mobility and can move quickly under its own propulsion from drill site to drill site in contrast to semi-submersibles and jackup barges and platforms. .
A drillship is a merchant vessel designed for use in exploratory offshore drilling of new oil and gas wells or for scientific drilling purposes. In recent years the vessels have been used in deepwater and ultra-deepwater. .
A drillship can be used as a platform to carry out well maintenance or completion work such as casing and tubing installation, subsea tree installations, and well capping. Drillships are often built to the design specifications set by the oil production. .
There are different types of units such as the , , , platform and of course drillships. All drillships have what is called a ”moon pool”. The is an opening on the base. .
The first drillship was the , designed by Robert F. Bauer of Global Marine in 1955. The CUSS I had drilled in 400-foot-deep waters by 1957. Robert F. Bauer became the. .
Drillships are just one way to perform various types of drilling. This function can also be performed by , jackups, .

[pdf] If the hydrostatic head of the drilling fluid is insufficient to control subsurface pressure, formation fluids will flow into the well. To maintain well control, back pressure is applied by routing the returns throug.

Our ACD system is the industry’s first active, non-rotating sealing device for MPD operations. The ACD seals the wellbore annulus and diverts returns using a novel, actively energized sealing element controlled by our industry-standard annular packer system. The design allows the system to determine the sealing. .
Our Drill String Isolation Tool (DSIT) is an industry-leading riser annular packer that fits a variety of purposes. As the backbone of most existing riser. .
Our flow spool is a common component in many MPD and RGH specialty joint systems. It serves as a conduit for drilling returns to exit the riser below an ACD and RCD and provides. .
The Compact Riser Gas Handling (RGH) system permanently integrates DSIT and flow spool functions in a single joint to remove connections and reduce weight. The compact RGH. .
Our unitized MPD specialty joint integrates our ACD, DSIT, and flow spool functionality in a single compact and lightweight joint. The approach provides the entire spectrum.
