Mar 19-23, 2005 Berkeley 8 Resources Full access to PSL shop and staff EHWD test area is still available EHWD test equipment 250 ft deep hole for hose test

Mar 19-23, 2005 Berkeley 9 Testing and Training Setting up software development and testing facility at PSL Setting up heater, pump, control and sensor facility at PSL Set up communication network for above Will use above for drill and repair training for drill crew May move to MDS style unit in future

Mar 19-23, 2005 Berkeley 11 Schedule We have started work already Must ship all items so they get to SP when it opens Organize shipments so parts are easily found We have about 6 months--must be very careful on what we do

Mar 19-23, 2005 Berkeley 12 Stay focused on goals Priorities: –Thing we must do1 –Things we should do2 –Things that would be nice3 Eliminate dependencies among tasks Keep an eye on how long it takes to do here Keep another eye on how long it takes to implement at the pole Keep both eyes on drilling 12 holes

Mar 19-23, 2005 Berkeley 13 Drill Logging and Analysis

Mar 19-23, 2005 Berkeley 14 Implementation--Introduction Layout-surveying Pilot holes—4” coring drill Firn Drill---down to 60 meters—water pools HW Drilling—straightness, depth, logging String Deployment—depth, location, logging Freeze-In—4-5 day monitoring-Counting House Data Management—drillers, deployers Off-line—real-time analysis, Pole, Madison

Mar 19-23, 2005 Berkeley 15 Drilling Data Drill Operations: depth, calipers, theta, vital parameters Data updates at rate of 4 Hz (250 ms). Data-Bridge—between drill net and SP-net. With updates every 5 minutes—1200 updates Drill Monitoring: Off-line, Real-Time Pole Monitoring---full analysis and logging Madison Monitoring—full analysis and logging as the satellite permits.

Mar 19-23, 2005 Berkeley 16 Off-line Real-Time Analysis At South Pole and Madison Tension (cable and drill-head) Depth (from winch payout and pressure) Hole Diameter—Calipers Drill-Angle—Straightness, Theta Logging X-Y or “birds-eye” plots

Mar 19-23, 2005 Berkeley 22 HOLE 1

Mar 19-23, 2005 Berkeley 23 Hole #1 Summary 22 hrs—large tilt angle, buried drill? hrs—buoyant drill, buried drill, lost nozzle? 40 hrs—buried drill, lost part of weights 43 hrs—lost additional part of weight-stack 45 hours buried drill hours, drill difficult to steer. Difficulty controlling hole diameter

Mar 19-23, 2005 Berkeley 24 Hole #2 (21-A) Move tower by about 8 meters Make 2 nd attempt at hole drilling

Mar 19-23, 2005 Berkeley 34 Drill Oscillations Demonstrates need for fast-response instruments like drill load-cells, and cable/winch load-cells. Possible need for additional instruments like accelerometers to actually determine drillhead’s instantaneous velocity and position.
