01:00 - 04:00: Held toolbox talk prior to skidding rig from f-1 to f-14. Skidded rig 3 m starboard. Skidded rig/cantilever 6,5 m aft. Removed hatches in wellhead module on f-14. Ran stand of HWDP through rotary and made final adjustments.
04:00 - 06:00: Broke down stand of 5 1/2" HWDP and laid out three joints for backload and inspection. Rebuilt stand with 3 new joints of 5 1/2" HWDP and racked back in derrick. Ran tugger from moonpool to seabed to help ROV clear CTS hose.
06:00 - 07:00: Picked up 26" drilling BHA and brought to v-door. Meanwhile helped ROV to clear hose trapped below template using tugger.
07:00 - 08:15: Held toolbox talk prior to making up 26" drilling BHA. Removed masterbushing and ran 26" bit GMWD assy through rotary. Inserted GMWD probe in BHA as per scientific instructions. Meanwhile ROV attempted to connect hose to CTS funnel. CTS hose was too short and the funnel had to be turned. ROV lost 3-finger claw when attempteing to turn CTS funnel.
08:15 - 09:00: Continued running BHA. Picked up and made up MWD/UBHO assy. Meanwhile pulled ROV to surface for repair.
09:00 - 09:30: Orientated UBHO sleeve as per scientific instructions. Meanwhile repaired ROV manipulator claw.
09:30 - 10:45: Made up 3 x 9 1/2" NM DC to BHA and ran in to 63 m MD. Repaired ROV and launched same. Assessed video recording from incident. Found 3-finger claw to be lost in hole. Assessed situation.
10:45 - 11:45: Laid out 1 x DC and made up hydro- mechanical jar to 8 1/4" DC stand. Racked back in derrick. Discussed way forward with town.
11:45 - 12:30: Awaited further instuctions. Discussed way forward with town. Decided to run in with 26" rock bit BHA in attempt to remove junk in hole.
12:30 - 15:45: POOH with 26" drilling BHA. Racked back BHA in derrick. Laid out UBHO/MWD assy on deck.
15:45 - 16:00: Held toolbox talk prior to making up new 26" junk removal BHA with rock bit.
16:00 - 17:00: Made up 26" bit and bit sub to stand of 9 3/4" drillcollars. Removed masterbushing, ran stand through, installed masterbushing and hung off assy in rotary table.
17:00 - 18:00: Made up jar and 8 1/4" DC stand. Picked up single 8 1/4" DC and made up same.
18:00 - 19:00: RIH with 26" junk removal BHA on 5 1/2" HWDP from 70 m MD to 175 m MD. Stabbed into CTS on top of conductor housing while observing with ROV.
19:00 - 19:45: Washed down from 175 m to 183 m MD with 1000 LPM and tagged cement with 5 MT. Applied 4-6 MT wob and rotated at 15 RPM down to 185 m MD.
19:45 - 20:30: POOH with 26 junk removal BHA from 185 m to just above CTS funnel at 138 m MD. ROV inspected 26" rock bit. No damage or junk could be observed.
20:30 - 20:45: Ran back in to 185 m MD to resume drilling cement. Connected CTS hose to ROV and started pumping with dredge pump.
20:45 - 23:30: Drilled cement from 185 m to 197 m MD. Drilling parameters flow 4400 LPM SPP 62 bar rotation 45 RPM torque 1-3 KNM. Controlled penetration rate to 15 m/hrs. Observed higher wob 15 m/hr) from 193 m to 197 m MD indicating hard cement. 20 MT tonne wob peak at 193 m MD and 3-10 MT downwards. Observed excessive rattling in string and wob peaks around shoe depth at 197 m MD. Pumped 2 x 20 m3 hi-vis sweeps to clean hole.
23:30 - 00:00: Drilled rathole and shoe from 197 m to 201 m MD. Drilling parameters flow 4400 LPM SPP 62 bar rotation 45 RPM torque 1-2 KNM wob 1-2 MT. Reamed back inside shoe for every 2 m drilled.
