Hourly activities:
00:00 - 01:00: Bled off pressure to 0 bar above DHSV. Confirmed valve status and handed over well to drilling at 01 00.
01:00 - 02:00: Transferred HMV and DHSV to local controled panel lock-out mode). Connected seawell pump and tested line up.
02:00 - 03:00: Installed test and bleed manifold from moonpool outlet to XMT KWV. Prepared bleed down hose and valves from KWV to closed drain.
03:00 - 04:30: Flushed lines and attempted to perform line test to 30/200 bar for 5/10 min from CMT unit to KWV through test and bleed manifold. Had 8 bar increase on low pressure test. Investigated situation. Performed test" for CMT unit seperatly. OK. Performed line test to 30/200 bar for 5/10 min from CMT unit to KWV through test and bleed manifold.
04:30 - 06:00: Opened KWV and attempted test XMT cross. Pressure dropped from 20 to 8 bar while pumping and from 26 bar to 11 bar on second attempt. Checked line-up for leaks. No leaks observed. Opened SV. Flushed through XMT through tree cap needle valve. Closed SV and re-attempted to test XMT cross. Pressure dropped from 30 to 8 bar. Closed ltv1 and performed a second line test to 30 bar/5 min. OK. Opened ltv1 and re-attempted to test XMT cross without sucess.
06:00 - 06:30: Closed MMV to establish if it was HMV or PWV that was leaking. Re-attempted to test XMT cross without sucess.
06:30 - 09:00: Operated and greased up PWV.
09:00 - 10:30: Verified PWV, SV and HMV were closed. Leak tested XMT cross to 30/200 bar for 5/10 min using CMT unit and 100 MEG. Had 2. 4 bar drop 2 min. Bled off pressure to 0 bar to platform closed drain. Verified no pressure below treee cap and removed same.
10:30 - 11:00: Held tool box talk for installing WL riser and lubricator and change elevator. Lifted WL riser sections and BOP with top drive using double lift arrangement. Lowered and stabbed on to XMT connection.
11:00 - 12:30: Changed elevators and PU lubricator. Meanwhile pressure tested shear ram on WL BOP to 30/200 bar for 5/10 min. OK.
12:30 - 13:00: Man-rode to turn WL sheave wheel.
13:00 - 15:00: MU combination toolstring in riser and stabbed on lubricator with in-situ sub.
15:00 - 16:15: Verified that toolstring was sitting in toolcatcher. Opened SV 10 turns and opened KWV. Filled riser with 100 MEG from CMT unit. Leak tested WL riser, BOP and lubricator to 30/200 bar for 5/10 min using CMT unit and 100 MEG. OK. Bled off pressure to 0 bar. Closed SV and KWV.
16:15 - 16:30: Performed well control exercise with seawell, schlumberger and m rsk crew.
16:30 - 18:15: Opened HMV, KWV and SV 10 turns. Filled well above DHSV with 7. 7 m3 100 MEG. Equalized and opened DHSV at 93 bar. Closed KWV and bled off pressureto 0 bar in manifold.
18:15 - 19:00: Opened SV with 45 turns. RIH with combination toolstring on 7/16" EWLL to 485 m and took pick up weight.
19:00 - 19:15: Attempted to RIH through DHSV, but found solid hold up depth at 498 m.
19:15 - 20:45: Changed out MEG tanks and re-filled MEG on CMT unit. Meanwhile held tool box talk prior to equalizing and opening DHSV. Performed well control exercise with seawell, schlumberger and m rsk crew.
20:45 - 21:30: Opened ltv1 and ltv2. Equalized pressure to 90 bar and opened KWV. Pumped 8. 95 m3 100 MEG into well and observed pressure drop from 90 to 69 bar. This confirmed that DHSV was open/partly open.
21:30 - 23:15: Attempted to RIH through DHSV, but found solid hold up depth at 498 m. Discussed further options.
23:15 - 00:00: Functioned DHSV closed/open twice to remove possible debris. Had 3. 0 dl return when closing DHSV and pumped 4. 25 dl when opening DHSV. Had good indication of DHSV being in open position.

24-hour summary: Operated and greased up leaking PWV. Leak tested XMT cross to 30/200 bar for 5/10 min. Installed WL BOP and riser on XMT. Tested shear seals on WL BOP. Installed combination toolstring in riser. MU lubricator. Leak test WL riser, BOP and lubricator. Equalize and open HMV and DHSV. RIH with combination toolstring and tagged TCP guns at 3260. 5 m. Performed correlation log in 7" liner. POOH and prepared for inflow test of HMV.
