Winch, Deep Logging

2014 Spring

New Technology for the Community

Deep Logging Winch
The new IDDO Deep Logging Winch system, capable of logging to depths of 4,000 meters, is completely built, tested, packed, and ready for future field projects. The list of necessary spare parts is created, but the spares will not be purchased until a project utilizing the winch is funded.

"Clow" Deep Logging Winch
During the Second Quarter, the deep logging winch designed, built and operated by Gary Clow was transferred from the U.S. Geological Survey to IDDO. The winch is currently in Antarctica and will be used for the logging of the WAIS Divide deep borehole during the 2014-2015 field season. IDDO anticipates that the logging winch will be returned to Madison, inspected and repaired as necessary prior to use on any future projects.

Equipment Development

Deep Logging Winch
In the first quarter of PY 2014 (Nov-Jan), IDDO completed the building and testing of a new Deep Logging Winch, capable of reaching the depth of 4,000 meters. At the end of the quarter, the logging winch system required only the completion of the shipping container for the logging tower to be ready for shipment to the field.

Equipment Development

Deep Logging Winch
The manufacturer (Markey Machinery Co.) delivered the Deep Logging Winch in early September. IDDO personnel are in the process of completing the design of the winch sled and minor modification to the winch control system. The winch is scheduled for completion in early 2014.

Equipment Development

Deep Logging Winch:
IDDO finished specifications of the 4000-meter Deep Logging Winch and placed an order with Markey Machinery Company, Seattle, WA. On March 19, IDDO approved the certified drawings of the entire system developed by the manufacturer, and the winch is in the process of being produced.

Deep Logging Winch

Acquisition of a deep logging winch capable of logging boreholes 4000 meters deep is one of the high-priority items identified in the Long Range Science Plan. Through many IDPO discussions with the borehole logging community and with IDDO, a set of science requirements for a deep logging winch have been developed and are available at:

Erin Pettit, Ryan Bay, and Gary Clow will serve as the chief scientists for the deep logging winch development. The corresponding engineering requirements for the winch were developed by IDDO.

Three bids from manufacturers that are willing and capable of building the winch were received by IDDO and a "winner" identified. IDDO has started working with the manufacturer to ensure that the winch will meet the engineering and science requirements.
