comments: Made x-y measurements on conductor relative to funnel :
fwd 38 cm / aft 34 cm / stb 34 cm / port ?? cm (unreliable data due to bad access).

comments: Circulated hole to seawater before cementing. Stepped pumps up to 1500 lpm. No annulus returns could be observed by ROV. Inspected template for returns elsewhere but none could be observed. No return observed after 60 m3 pumped. Hookload rose from 100 MT to 110 MT during displacement indicating lighter fluid in annulus.

comments: Increased pump rate to 2000 lpm. Pumped another 40 m3. After 15 min pumped, observed returns from annulus. Hookload levelled out at 112 MT.

comments: Attempted to mix and pump cement. Had severe problems transferring dry X-lite cement from bulk system to surge tank. Automatic transfer system was not working. Could not keep a steady transfer rate by manual operation. Not possible to obtain prescribed cement slurry. Pumped 12 m3 cement of varying weights at slow rate. Aborted operation.

comments: Displaced cement to drillfloor and circulated out same by pumping 40 m3 of seawater at 2000 lpm with rigpumps. Meanwhile washed cement unit and troubleshot bulk transfer system. Rig air pressure insuffcient to operate cement bulk system.

comments: Mixed and pumped 60 m3 1,52 sg tuned light cement slurry. Pump rate 800-1100 lpm. Pump pressure 20 bar. Displaced cement with 6,5 m3 seawater to put theoretical top of cement at 217 m MD inside conductor. Hookload during cementing fell from 110 MT to 100 MT indicating annulus displaced to heavier fluid.

Meanwhile :
-Retrieved hotstab and guidewire
-Continued work on aft PRS
-Installed new rubber conveyor belt on HTS
-Started work on tensioner cylinders on F-14
-General PM on drillfloor

comments: Performed toolbox meeting prior to disconnecting CART. Slacked off 10 MT to obtain neutral at CART. Disconnected CART from conductor housing with 5 righthand turns. Lifted out CART and set slips on landing string. Broke out and laid down cementing stand. Pumped 2 ea sponge balls at 2500 lpm  to clean string. Reading on inclinometer before disconnect : pitch 0,34 deg / roll 0,06 deg.
