The rotational ball seat (RBS) is a ball-type tubing-blockage device that is run in the liner setting string for the COLOSSUS CMT cemented liner hanger system and the COLOSSUS UNC uncemented liner hanger system. When pressure is required to set hydraulic liner systems, a drop ball is released from the surface and lands on the ball seat contained within the RBS. Increasing the pressure above the predetermined shear value causes the ball seat to shear and rotate down. The ball is released, and a smooth and full ID remains through the tool.
