6 FAQs about [Refitting deepwater drilling rig]

Can a rotating control device be installed on a deepwater rig?

Installing specialized equipment, such as a rotating control device, on deepwater rigs can be cost-prohibitive as there is still a relatively small number of MPD applications in that segment. The rocks being drilled today demand more than a better set of tools; they require a different approach to well construction.

What are deepwater Titan & deepwater Atlas rigs?

The two eighth-generation drillships we recently put to sea— Deepwater Titan and Deepwater Atlas —were designed to deliver outstanding performance for our customers. Both operating in the U.S. Gulf of Mexico, they are the first rigs in the world equipped with a 1,700-ton hoisting system, 20,000-psi well control system, and 10,000-psi mud system.

Does deepwater FID support long-term rig demand?

There are at least 15 regions of the world with deepwater FID potential to support long-term rig demand. All have widely varying degrees of potential, risks and timelines. The Orange Basin in Namibia screens as potentially most impactful on rig demand after various discoveries in 2022-2024.

Should MPD be more available for deepwater drilling?

Making MPD more available for deepwater drilling requires a coordinated effort on multiple fronts to streamline and standardize as much of this process as possible. At stake is an immediate improvement for process safety and the ability to mitigate and eliminate many pressure-related deepwater drilling hazards.

Do Drillships have a problem?

The problem drillships have is the carry cost while idle. An offshore rig incurs warm stacking costs when idle with no revenue. While offshore rigs await production equipment delivery, they need to work or face warm stacking costs. The market has demonstrated price discipline thus far, although we may see an example or two testing it in 2025.

What is a rig survey?

A rig survey is usually performed to establish deck loads and footprints, power and other MPD requirements. Modifications are often required, which can add significantly to time and costs. In some cases, major modifications must be made to riser components, such as slip joints and tension rings.
