1. A method for drilling a wellbore, comprising:
positioning a rotating control device housing along a riser;
mounting a seal rotating system to a running tool;
connecting the running tool into a drill string;
lowering the seal rotating system into the rotating control device housing via the running tool;
releasing the seal rotating system from the running tool; and
moving the running tool down through the seal rotating system with the drill string for a wellbore drilling operation,
wherein the mounting comprises: resting the seal rotating system on a shoulder of the running tool; and securing the seal rotating system to the running tool with shear bolts, and
wherein securing the seal rotating system to the running tool comprises threadably engaging the shear bolts with removable bushings of the running tool,
the method further comprising providing a greater number of the removable bushings than the shear bolts to facilitate securing the seal rotating system to the running tool at a variety of different rotation angles.
