The Rig is to be sold as is where is, and as stated by before, we have all the relevant people to help get the rig out of Angola if needed.
As I think I have said, the rig had a full refurbishment in Dubai in 2007 ready for its drilling programme for xyz in 2008.
The rig did a short five well drilling programme for xyz and has been awaiting further opportunities since being stacked but none have been forthcoming.
From the original rig the only items used were the Mast, Sub-Structures (and cross members, new end toenails were made for raising and lowering of the mast), the Drawworks and Doghouse.
The mast and substructures had a full shot blasting, inspection and re-certification by 3-C Metal International, Drilco Field Inspection Services, MH – Pyramid, Southern Technology Services and Slaton Engineering Ltd.
The Drawworks also had a full strip down, inspection and rebuild by Wood Group and was fitted with two new DC traction motors.
New Rotary table beams were purchased as well as a new rotary table and DC drive motor. Photographs of the internal workings of the Drawworks were taken by November 2014. The remainder of the rig components, but not limited to, Generator package plus SCR building, 2 x 1600hp Mud Mumps, Mud Tanks, BOPs, manifold and Accumulator were all purchased new for the drilling programme.
The rig camp and main camp were purchased new from abc for the project but some of the accommodation buildings and office blocks have been sold on. The main camp and rig site camp generators are still with the rig also the two water treatment plants, freezer block and some other buildings are present.
As the rig has been stacked for a while it will need a full recertification on some of the major components of the rig, I would also advise thickness checks on the Fuel tanks, Mud Tanks and HP Pipe work.
We have started a work scope spreadsheet for Rig 80 to bring it back up to its original condition. Although the rig does not have a top drive a five-foot mast extension was made while the mast was being inspected in case a top drive was needed in any future drilling projects, there is a bay available for this in the SCR room as the one for the Rotary Table DC would not be needed if a top drive was used.
