Oil Rigs Now serves as an independent marketing platform that connects buyers with listings for ultra deepwater semisubmersible rigs, offering detailed insights to help make informed purchasing decisions. The platform lists rigs from various sellers.
What Are Ultra Deepwater Semisubmersible Rigs?
Ultra deepwater semisubmersible rigs are floating platforms designed for drilling in deepwater environments, typically in water depths greater than 1,500 meters. These rigs are anchored to the seabed with multiple lines and can operate in harsh conditions, making them suitable for exploratory and production drilling in challenging offshore locations.
Advantages of Ultra Deepwater Semisubmersible Rigs
These rigs offer several advantages for offshore drilling:
- Stability: The column-stabilized hull rides low in the water, which reduces motion in rough seas.
- Versatility: They can be used for various drilling operations, including exploratory and development drilling.
- Deepwater Capability: Current listings are rated for water depths from 5,000 ft (as outfitted) to 9,840 ft.

These figures are the sellers' own spec sheets as listed. Confirm each one against the equipment and its paperwork during an independent inspection.
Note the gap between design and outfitted water depth on the 2009 unit. A rig can only work as deep as its mooring and riser allow, so check the outfitted figure against your program.
Frequently Asked Questions
What is the typical condition of the rigs listed?
Rigs listed on Oil Rigs Now are sold as-is by their owners. Buyers are encouraged to conduct their own due diligence on any rig of interest.
How can I arrange inspection of a rig?
Buyers can hire independent inspectors before purchasing any rig.
How are payment terms handled?
Payment terms are set by each seller. Ask about them when you inquire about a specific listing.
Moored or dynamically positioned: which do I need?
Moored rigs hold station on anchors and suit most deepwater wells inside their mooring depth. Dynamically positioned rigs hold station with thrusters and can work deeper water and congested seabeds, at a higher fuel burn. Some rigs, like the 2016 sixth-generation unit, carry both.
Which survey records matter most on a semisubmersible?
Hull survey status and the next special periodic survey date, the BOP recertification history, riser inspection records and, on DP rigs, the DP equipment notation and FMEA. These drive both the reactivation budget and the schedule.
