Steel Caisson and Drilling rig

Steel Caisson and Drilling rig

Drilling rig on a Steel Caisson is one of the drilling rig design concepts for offshore shallow water environments.

1. Water depth range: 5 – 100m however must be designed for a limited water depth range, unless berms are considered.  More study required to ascertain minimum water depth capability of concept with & without rig installed for positioning

2. Low environment impact.

3. Suitable for ice. The concept has been used successfully in the Beaufort Sea and Canadian Arctic,  though in deeper water e.g. Hibernia, Molikpaq . . .
