SLANT RIG SELF ELEVATING STRUCTURE

RIG DESIGN

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.
