comments: Pumped 500 ltrs water, released dart and continued pumping 2500 ltrs water behind cement with cmt unit. Top wiper plug sheared at 170 bar. 

Zeroed stroke counters for mud pumps. Displaced and sheared btm wiper plug by pumping OBM at 1200 lpm using rig pumps. 
Continued displacing cement with 111.9 m3 OBM at 1770-1500 lpm using mud pumps. Wiper plug sheared at 114 bar / 4450 stks. Slowed down rate to 1000 lpm / 69 bar (FCP) approx 4 m3 prior to bump. Bumped plug with 138 bar after pumping 5080 strokes, which gives a pump efficiency of 96.5%. No losses during displacement.

comments: Equalized pressure with cmt unit and opened lo-torque valve. Pressured up well to 345 bar / 15 min to test casing using cmt unit. Ok. 1250 ltrs pumped and got 1220 ltrs back. Bleed off from 345 bar to 138 bar and checked for back flow to cmt unit. Lined over to rig pumps and bled off from 138 bar to zero on stand pipe. Checked for back flow. Disconnected cmt hoses and flushed lines.
