Submersible drilling rig

Submersible driling rig is one of the drilling rig design concepts for offshore shallow water environments.

1. Could operate in water depth of 3 to 30 m.

2. Environmental Impact Potentially low.

3. Can be designed for ice operations.

4. Suitable for exploration.

5. Would have to be built outside the Caspian and imported.

6. Any rig size can be fitted.

Other drilling rig design concepts for shallow water depth environments will include:

1. Land rig on artificial island

2. Land rig on barge (with optional submerged caissons)

3. Swamp Barge (With Optional Submerged Caissons)

4. Standard Jack-Up

5. Shallow Draft Jack-Up

6.Semi-Submersible

7. Cantilever Drilling Barge

8. Steel Caisson with Drilling Rig

9. Modularised and Pile Elevated Drilling Rig

10. Drilling Rig on Pre-Installed Piles and Modules

11. Jacket Supported Offshore Rig

12. Posted Barge With Land Or Modular Rig

13. Heli-Rig

14. Submersible
