Modularised and Pile Elevated Drilling Rig is one of the drilling rig design concepts for shallow water environments.
1. Water depth range: 2 – 10m
2. Low environment impact. Installation and removal of piles may be complex.
3. Suitable for ice. Piles dimensions and clearance could be designed so that berms and/or ice rubble makers are not necessary.
4. Suitable for exploration. Designing the rig to cantilever over the side of barge would permit low numbers of production wells to be drilled.
5. Concept only. Can be fabricated locally. If built outside on 15 m wide barges it could be transported on the Don Volga with minimum assembly required.
6. Enables quick mobilisation in shallow water outside the water depth of a swamp barge. Best suited to a small rig.
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)
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
