comments: Pulled back one single. Broke connection using the iron roughneck. Continued to RIH. Stabbed conductor into guide funnel at 03:30 hrs. Checked orientation of conductor shoe. Observed a broken connetion on the top up cement system. Continued to run the conductor to 160 m. Observed 20 tons weight. Worked conductor down to 169 m.

comments: Held a toolbox meeting. Rigged up tugger on centralizer deck and pulled conductor to starboard aft. Guided the conductor carefully through the guide funnel to 180.2 m to avoid further damage on top up cement piping. Washed down with 30" conductor from 180.2 m to 190 m, 1000 lpm. Observed leakage in top up cement piping at approx. 11 m below top housing.
