comments: Raw water pumpe failed and left rig with only 1 out of 3 pumpes available. Due to the criticality of the pump delivering firewater, cooling water etc the drilling operation is postphoned until the pump is replaced. 

-Meanwhile held tool box meeting to install diverter elements. Removed master bushing and  replaced torn 22" outer diverter elements by new 18" elements.
-Meanwhile held tool box meeting prior to POOH. POOH with 8 1/2" BHA from 212 m to 32 m.
-Meanwhile cleared rig floor before handling radioactive sources. Removed batteries.
- Meanwhile continued POOH to 17 m.
