00:00 - 02:00: Continued working to replace adapter ring on annular BP. Found hard cement around annular BOP. Meanwhile worked on replacing slew motor on aft PRS. Pressure tested bleed of manifold on XT deck 20bar/5 min, 345bar/10 min. Connected hose and filled a-annulus and b-annulus with water.
02:00 - 03:30: Continued working on BOP and PRS. Errected scaffolding above choke manifold. Worked to connect hydraulic pump to locally control DHSV and HMV
03:30 - 05:30: Continued working on BOP adaptor ring. Test run PRS. Carried out TBT for pressure testing rig floor manifolds. Worked to pressure test rig floor manifolds. Prepared rig floor to lay out 7in TBG from the derrick
05:30 - 08:30: Attempted to instal adaptor ring, not able to land out all the way, 3. 5cm short. Pulled adaptor ring. Started to lay out 7in TBG from the derrick. Worked to pressure test rig floor manifolds
08:30 - 10:15: Rig power system shutdown due to turbine issues
10:15 - 14:00: Installed adaptor ring, installed annular BOP. Worked to lay out 7in TBG from the derrick, worked to pressure test rig floor manifolds. Cleaned and cleared BOP after re-building annular. Alarm went on on primary cooling pump for cabinets unit equipment). Inspected cooling pump, confirmed leak, switched cabinets cooling system to backup.
14:00 - 14:15: TBT to remove hatch on f-15 and instal half-moon hatch
14:15 - 16:30: Lowered down 2x half-moon hatches from moon. Removed hatch on f-15 and lifted hatch up into moon pull. Installed half-moon hatches over well f-15. Double secured lifts.
16:30 - 17:00: TBT for handling and preparing cement spool
17:00 - 18:00: Lifted up cement spool and shifted load from 35t cranes to 2x 6t rig floor tuggers. Double secured lifts
18:00 - 19:00: Lowered down cement spool onto XMT and m/u same using bx156 seal ring
19:00 - 21:30: Installed hole covers and tarpoulin in moonpool. Performed TBT w/ scaffolders. Built scaffolding around cement spool. Meanwhile worked on housekeeping in moonpool and carried out TBT for pressure test cement spool
21:30 - 23:00: Lined up and flushed from cement unit to cement spool. Pressure tested cement spool to 20/345 bar for 5/10min. Good test.
23:00 - 23:30: Performed pre-job meeting before bulheading operation. Meanwhile started greasing XT valves
23:30 - 00:00: Confirmed line up from mud pumps, meanwhile continued greasing valves and added surfactant into wash pill

24-hour summary: finished work on annular BOP adaptor ring riged up cement spool on top of XT built scaffolding in moonpool pressure tested cement head manifold
