Equipment

IDDO maintains and operates existing drills and borehole logging winches, and develops new systems with two principal foci:

  1. to provide high quality ice cores, and
  2. to produce boreholes that provide access to the interior and beds of ice sheets and glaciers for such purposes as embedding instruments, collecting gas samples, setting seismic charges, studying subglacial processes, studying subglacial geology, collecting subglacial bedrock core, and borehole logging.
 

Logging Tool Testing at IDDO

Below is some useful information to questions that usually get asked by the community prior to testing their logging equipment in the IDDO Pressure Vessel.

Location

Equipment that needs to be tested can either be brought with the investigator to Madison or can be shipped to the IDDO Warehouse in advance to the attention of Anna Claussen or the individual IDDO Engineer working with you for the testing.

IDDO Home Office

University of Wisconsin-Madison
AOSS/SSEC Building
1225 W. Dayton Street

Madison, WI 53706

IDDO Warehouse

(Testing Location)
1 Marsh Court

Please be sure to provide tracking information to ensure your device is properly received at the off-campus IDDO Warehouse, as the warehouse is not staffed at all times.

Coordination

  • Please coordinate all testing with Anna Claussen or his designee
  • Actual testing of the your device will be performed under the guidance and assistance of another IDDO engineer
  • Testing will occur at the off-campus IDDO warehouse
  • Prior to the testing, investigators should draft a test plan, outlining their desired objectives for the testing, any connectivity or power requirements and any safety concerns or other questions
  • The IDDO engineer will review the plan and will discuss any questions or concerns with the investigator
  • Both the IDDO engineer and the investigator will approve the test plan prior to initiating the testing

Pressure Vessel Specifications

  • Internal Diameter: 10 inches
  • Internal Length: 120 inches
  • Cylinder tested to 5000 psi per JARP J-102 specification
  • Vessel can only be operated and pressurized by an IDDO engineer and with an IDDO approved fluid.
  • Hydrostatic testing is the only method of pressure testing at IDDO.
  • Gearhart-Owen pigtail terminated through bulkhead connector to the external terminal block.

Logging Winches

Connector Information

Intermediate Depth Logging Winch

  • Amphenol pinout is:
    A = CL1
    B = CL2
    C = CL3
    D = CL4
    E = Armor
    F = (open)
    G = Enc A
    H = (open)
    J = Enc B
    K = (open)
    L = Enc Gnd
    M-U = (open)
  • Surface tool connection: Amphenol PT06A-14-18P
  • User connection: Amphenol PT02A-14-18S or PT01A-14-18S

IDDO Deep Logging Winch

  • Pins A-D are the internal conductors
  • Surface tool connection: Amphenol PT02E-8-4PW
  • User connection: Amphenol PT06E-8-4SW

USGS Logging Winch

  • Pins A-D are the internal conductors
  • Pin H is the armor
  • Surface tool connection: Amphenol MS3102A-18-8P
  • User connection: Amphenol MS3106A-18-8S

On all three winches, wiring is straight through A-A, B-B, etc. and uses the positioning detailed above. View shown is looking into the GO cablehead.

Note: For all three winches, on user side of Amphenol connections, the shell designation letter can be varied:
A = general duty
E/F = sealed w/ strain relief
R = lightweight sealed

Syncing the Payout/Tension Data
