Basic and detailed engineering of a self-elevating structure for a 35° slant rig. This rig was initially designed to drill water wells with no BOPs. The deeper drilling depth requires a BOP system, which was not originally planned. The structure was designed to lift the drilling truck by 3,7m to allow installation of 11” or 7” BOP stacks.
Activities / Tasks and Solutions developed by Dolfines
Dolfines has provided detailed engineering of the elevating structure.
Project Results
The structure is in service in Gabon for Perenco drilling operations.
