Hourly activities:
00:00 - 02:15: Closed DHSV and bled off above to 5 bar above. 120 ltrs bled back indicating DHSV not closed. Opened DHSV and pressured up and equalized above to 50 bar. 120 ltrs pumped. Observed drop in pressure on bot pump indicating DHSV open, but had only 280 ML bled back. Repeated sequenze 2 more times before we got good indication that DHSV was fully open and had 220 ltrs bled back. Repeated function test of DHSV. Closed DHSV and bled off above to 5 bar. 80 ltrs bled back. Observed for 10 min to confirm that DHSV was fully closed and not leaking. OK. Opened DHSV and pressured up and equalized above to 50 bar. 80 ltrs pumped. Observed drop in pressure on bot pump indicating DHSV open. Bled off pressure down to 5 bar. 220 ltrs bled back.
02:15 - 03:30: Pressured up tubing from 5 bar to 380 bar. 1386 ltrs pumped. Kept 570 bar on DHSV CL. Held pressure for 15 min to set packer and test tubing. OK. Had 1. 3 bar drop. Observed load vibration noise on rig floor when pressure reached 260 bar. Investigated th and all well head levels. No findings. Bled off tubing pressure and observed pressure dropped immediately to zero. Concluded that lead target blocked CMT line. This was in accordance with observed noise. Bled off tubing pressure carefully to zero. Had 1360 ltrs bled back.
03:30 - 04:00: Lined up through CMT kill line. Performed line test 30/380 bar for 5/10 min. Had 1. 4 bar drop.
04:00 - 05:30: Pressured up tubing to 330 bar while keeping 570 bar on DHSV CL. 1157 ltrs pumped. Closed DHSV and bled off pressure above DHSV to 260 bar. 20 ltrs bled off. Inflow tested DHSV to 70 bar diff/15 min. Had 1. 3 bar drop. Bled off pressure above DHSV to 10 bar. 140 ltrs bled back. Inflow tested DHSV to 320 bar diff 30 min. Had 0. 1 bar increase. Equalized pressure by pressuring up to 330 bar above DHSV and opened DHSV. 220 ltrs pumped. Bled off pressure in tubing to zero and kept DHSV open with 570 bar. 1000 ltrs bled back.
05:30 - 06:00: Lined up CMT unit to a-annulus, with hose connected to multibowl and tested RU to 35/380 bar for 5/10 min against annulus valve. Vented b-annulus.
06:00 - 06:30: Performed line test to a-annulus to 35/380 bar for 5/10 min against annulus valve using packer fluid. High pressure test dropped 1 bar in 10 min. Opened b-annulus to vent.
06:30 - 09:15: Pressured up a-annulus to leak test packer from below and th from below to 35/380 bar for 5/10 min pumping brine at 70 LPM. Kept tubing open on drill floor and 570 bar on trscssv CL. Pumped 117 ltrs and observed 0. 01 bar drop on low pressure test. Pumped 1170 ltrs and observed 0. 5 bar drop on high pressure test. Had flow on both tubing and b-annulus while pressuring up a-annulus due to ballooning effect. No flow observed when pumps was shut in. Bled pressure down to zero and had 1100 ltrs in return. Bled off and shut in a and b-annulus. Closed trscssv. Had leak in FWD PRS.
09:15 - 10:00: Worked at hight and repaired hydraulic leak in FWD PRS.
10:00 - 12:00: Held tool box meeting. Released landing string by 9 right hand turns. POOH and LD landing string.
12:00 - 13:15: RD odfjell CSG tong and control box. RD tubing handling equipment.
13:15 - 15:45: Held tool box meeting. Changed to 5 1/2" handling equipment. PU and MU XO 5 1/2" FH box x 3 1/2" if box to centralizer BPV running adaptor BPV. RIH and landed BPV on 5 1/2" DP in th at 20. 3 m. Sat down string weight to extend locking keys and energized seals. Rotated string 8 1/2" turns clockwise to lock mandrel and free running adaptor in j-slot. POOH with running string and LD RT.
15:45 - 18:00: PU 2 joints of 5 1/2" HWDP and RIH and drained riser. Lo jnts. Meanwhile cleared rig floor of CL wheel, protectors and x-overs. Prepared slings for diverter and double lift for surface riser.
18:00 - 00:00: Held tool box talk. Attached slings to slick joint. Prepared barriers, handrails and slings. Pulled diverter and secured in set back area. Installed outer ring and master bushings. Loosened nuts on slick joint. Disconnected tension cylinders in WH module. Pulled slick joint and secured in set back area. ND nt2 connection on BOP and sat on stump.

24-hour summary: Tested a-annulus to 380 bar. Ran BPV and sat in th. POOH and LD landing string and th running tool. ND diverter, BOP and surface riser. Retrieved surface riser and lifted down space spool using double lift. Installed dart in BPV. Removed communication collar, terminated cls and installed seals for XMT. Installed space spool.
