comments: Reduced pump rate to 200 lpm. Dropped the ball from the cmt head with liner in tension and chased the ball with 500 lpm / 30.6 bar. Landed ball after 653 stks pumped. Pressured up to 135 bar. Held 2 min. Bled down to 70 bar. Sat down 25 MT of drill pipe weight to verify that hanger was set. OK. 
Continued to pressure up to 175 bar to relese setting tool. Held 1 min. Continued to pressure up to shear out ball seat. Sheared at 228 bar. PU to verify that liner was released. Up weight 158 MT / down weight 134 MT.

comments: Pumped 10 m3 base oil, 780 lpm / 80 bar and 15 m3 of 1.65 sg tuned spacer E+ at 665 lpm / 80 bar with mud pumps while rotating liner 15 rpm / 12 kNm. Lined up to cmt unit through cmt hose. Dropped dart to release bottom wiper plug. 

Mixed and pumped 15.9 m3 1.90 sg cement slurry at 680 lpm / 80 bar and displaced cement with 0.9 m3 freshwater to rig floor. Dropped dart to release top wiper plug. 

Lined up to rig pumps and pumped 19 stks before flag indicated dart had dropped. Displaced cement with 45 m3 OBM at 1200 lpm, 15 rpm / 15-18 kNm with full returns. Slowed down pump rate to 500 lpm after 1930 strks. FCP = 42 bar. Stopped pumping after 2052 + 19 = 2071 strks pumped. Observed torque increased to 26 kNm after 2071 strks pumped, but had no bump.
