Drill Improvements2005-06—PSL Work Plan • Plans for getting there Issues People Resources Testing and training • Organization • Schedule • Stay focused on goals Mar 19-23, 2005 Berkeley
Goals for 2005-2006 • Set up as early as possible up to Dec 10 • 7 week drill/deploy period (Dec11, Jan 28) • Target drill speed 48 hrs/hole, including firn • Target deploy speed 24 hrs/hole • Use both towers to leapfrog • 2 strings per week • Drill and deploy 10-12 strings Mar 19-23, 2005 Berkeley
Drill performance issues • Speed limitations (deep drill and firn) • Second tower (shipped) • New crescent • Drill control software • Set up and hole-to-hole move • Fuel delivery systems • Generators Mar 19-23, 2005 Berkeley
Drill reliability issues • Motor drives and controls • Drill supply hose • Flow, temperature and pressures sensors • Heaters • Condensate pumps • E-stop false events • Weight stack • Load cells • Communication networks • Reels and reel brakes Mar 19-23, 2005 Berkeley

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
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

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
Stay focused on goals • Priorities: • Thing we must do 1 • Things we should do 2 • Things that would be nice 3 • 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
Drill Logging and Analysis Mar 19-23, 2005 Berkeley
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
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
Off-line Real-Time AnalysisAt 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

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. Mar 19-23, 2005 Berkeley
