08:45 - 09:00: Performed TBT for pressure testing cement spool
09:00 - 10:00: Continue building scaffolding hand rails and stairs for safe access to hatch deck. Meanwhile continued working on BOP, performed post-skid checks and housekeeping.
10:00 - 11:00: Lined up and flushed lines to cement spool. Pressure tested cement spool to 20/335 bar for 5/10 min. Bled off pressure to closed drain.
11:00 - 12:00: Lined up and attempted pressure tested kill wing manifold 20/335 bar. Leaking hose between kill manifold and cement spool.
12:00 - 13:00: Replaced leaking hose.
13:00 - 13:45: Pressure tested kill wing manifold to 20/335 for 5/10 min.
13:45 - 14:00: Performed TBT for bullheading SW
14:00 - 16:15: Opened HMV, 7 bar trapped below. Bled off pressure in well to 1,3 bar through closed drain.
16:15 - 20:30: Opened SV and trapped 10 bar behind LTV 7 on CMT spool. Opened LTV 7 and observed pressure drop, correct line up. Pressured up control line for DHSV to 520 bar. Bullheaded 3 m3 50/50 MEG/SW followed by 10 m3 wash pill at 200-400 LPM. DHSV equalized at 54 bar after 8 m3 pumped. Lined over to SW, and bullheaded SW at 1300 LPM. Observed pressure increasing to 305 bar after 76 m3 of SW pumped. Decreased flow to 1000 LPM, pressure decreased and stabilized at 245 bar. Increased flow in steps to 1300 LPM 273 bar. Continued bullheading 182 m3 SW at 1300 LPM, pressure decreased and stabilized at 1300 LPM 250 bar. Totally pumped 258 m2 of SW. Meanwhile performed TBT for cement job.
20:30 - 20:45: Shut down pumps and lined up to cement unit.
20:45 - 22:30: Closed LTV 7 and opened LTV 9. Released bottom dart. Mixed and pumped 12,3m3 1,90sg cement slurry at 600 LPM 175 bar. Displaced surface lines with 0,9m3 hi-vis pill from cement unit. Released top dart. Closed LTV 9 and opened LTV 11. Continued pumping 13,7m3 hi-vis pill from cement unit at 600 LPM 150 bar. Opened LTV 7 and LTV 9. Pumped 38,3 m3 SW at 1300 LPM 194 bar from cement unit. Cycled DHSV 3x times after 30 m3 SW pumped. Pumped 4,3m3 contamination pill from cement unit at 700 LPM 160 bar. Final squeeze pressure 208 bar. Final static pressure 96 bar. Stopped pumping. Estimated TOC at 2949 mmd.
22:30 - 00:00: WOC closed SV and bled off pressure in cement spool to closed drain. Meanwhile monitored pressure in XT cross from control room.

24-hour summary: r/u cement spool built scaffolding around cement spool and BOP stump pressure tested cement spool and kill wing bullheaded hydrocarbons back into well bullheaded cement in 7" liner WOC. Meanwhile prepare and perform BOP test
