14:45 - 15:45: P/u primary THRT, broke off damaged pup joint and l/d same. Replaced with new pup joint and m/u to THRT
15:45 - 16:00: P/u primary landing string
16:00 - 16:30: P/u 3x pup joints and m/u to THRT, RIH to 22m
16:30 - 16:45: POOH landing string to surface. Prepared and connected control lines to THRT
16:45 - 17:30: RIH with THRT and landed on the tubing. M/u THRT to th
17:30 - 17:45: Performed pre-job meeting for pumping open me plug
17:45 - 18:00: Dropped 2in ball inside landing string and m/u swedge with 1502 weco to 7in tubing
18:00 - 19:00: Lined up to line test. Go to low pressure 20bar. Cement pump tripped. Troubleshoot. Meanwhile lift remaining tubing handling equipment to rig floor. Reel and compact spider slips
19:00 - 19:15: Continued w/ line test. Meanwhile prepared rigfloor for second reel
19:15 - 20:00: Connected cement hose to pumping swedge and applied 20 bar to confirm line up. Continued to pressure up to 60 bar to stop at 50 bar due to pressure building up to fast), no indication of opening of the pump-open sub in me plug. Bled off. Waited 5 min to let plug reset. Note plug supposed to open at 40 bar.
20:00 - 20:30: Pressured up well to 50 bar w/ cement unit. Did not observe signs of pump-open sub in me plug openning Bled off pressure via choke meanwhile called and consulted interwell duty support. Agreed to pump up to 100bar to try to open plug. continued to rig up reels.
20:30 - 20:45: Started to pressured up well with constant rate of 50 l/min. Observed clear change of pressure trend at 56 bar indicating openning of pump-open sub in me plug stopped pressuring up at 102 bar
20:45 - 21:15: Bled off pressure and monitor well on fully closed choke, no pressure build up.
21:15 - 21:45: Pressured up well to equalize and open DHSV, applied 130 bar to string, observed DHSV equalizing and opening at 122bar. Pressured up control lines to 520 bar. Bled off tubing pressure to zero via choke to trip tank. Returns 60 liters indicating that DHSV closed after pressure above is pled off. Repeated equalizing and bleeding off sequence and observed same volume bled off
21:45 - 22:30: Confirmed 520 bar on control line and applied 140 bar to the well, 170 liters pumped and 90 liters returned. Meanwhile evaluated situation. Discussed situation w/ onshore organisation.
22:30 - 22:45: Applied 100 bar to tubing. Disconnected cement hose and bled off directly into a drum. 51 liters returned indicating that DHSV was closed
22:45 - 23:00: Reconnected cement hose to tubing. Meanwhile held TBT to swap hydraulic pump to pressure up control line for DHSV
23:00 - 00:00: Connected another hydraulic pump to control line, applied 520bar to control line. Started pressuring up tubing while monitoring gauge on the hydraulic pump for indications of DHSV sleeve movement. Observed DHSV equalized and opened at 146 bar and stop pressuring up at 152bar. No indication of DHSV sleeve movement. Bled off pressure, volume returned 60 liters. 152bar trapped below DHSV

24-hour summary: finished n/u BOP. Performed connector test RIH w/ THRT, locked to th open shallow set barrier plug troubleshoot communication w/ DHSV
