comments: Kept landing string in tension with an overpull of 3 MT while circulating. Establish circulation carefully in steps with SW through top drive to 2300 lpm 23 bars. Observed returns from F-5. ROV surfaced and picked up 4 conductor plugs, dived and installed conductor plug after having pumped 166 m³ of SW. Circulated 1 x casing volume ( 220 m³). Returns up F-15.  Pressure tested the cement line to 200 bars 10 mins. Meanwhile held tool box talk prior to perform cement operation of 20" casing.
