comments: 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.

comments: 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 (autodrill 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.
