Foro 1650 Drill

The third large compressor for IDP’s Rapid Air Movement (RAM) Drill received new plastic on its skis prior to shipment to Port Hueneme, CA, in mid-November. The compressor will travel on the resupply vessel to McMurdo Station, Antarctica, where it will be stored as a spare for the upcoming GHOST project (PI Anandakrishnan) on Thwaites Glacier.

Over the summer, the UW-Madison Space Science and Engineering Center (SSEC) secured additional space for IDP at the drill maintenance and warehouse facility. IDP’s electronics lab has been relocated to the new space, where the Foro 3000 and Foro 1650 Drill (previously referred to as the Intermediate Depth Drill or IDD) electronics are undergoing testing.

In preparation for the Detailed Design Review of the 700 Drill held on November 18, IDP engineers set up the Foro 400 Drill tent. The team believes a tent of very similar design could be used with the new drill slated to drill to 700 meters if fabrication is approved. A preliminary model of the 700 Drill subsystems can be seen below.

Foro 3000 Drill
IDDO continued initial development tasks for the Foro 3000 Drill system during the third quarter. Detailed design of the winch drum and level wind are in process. Sizing calculations were made and a design initiated for the chip melter system. Sonde assembly drawings were largely completed. Design work is expected to ramp up in the fourth quarter in preparation for a Detailed Design Review in late September.

Foro Drill
Anti-torque section assembly was largely completed and motor section assembly was initiated on the Foro Drill. Cabling was completed for the control box and drill motors were ordered. Shipping cases were received for the sonde, tower, and winch. Cutter head assemblies, spare cable terminations, and anti-torque slip rings were also received. Some assembly and testing have been delayed in light of work on higher priority projects, but procurements are largely complete.

Rapid Air Movement (RAM) Drill
Continued acceleration of RAM Drill design, procurement, and in-house testing. The system was prepared, packed and shipped to Scotia, NY in late June. In early July, IDDO received an Expedition Permit from the Government of Greenland, and a two-week field test was subsequently completed at Camp Raven in late July.

Intermediate Depth Drill
Models and drawings were completed for the winch cable terminations and spare cable termination kits were received for the Intermediate Depth Drill. System maintenance continues at a slow pace, as does the testing and troubleshooting of the Mage Controls components. The components, returned to Mage Controls at the end of the second quarter, are expected back at IDDO early in the fourth quarter.

Winkie Drill
Borehole casing was specified and purchased in preparation for the Winkie Drill's first use in West Antarctica at a drill site with overlying firn. IDDO sought information from international colleagues regarding methods to seal the bottom of the casing to the ice. Packer components, benchtop testing for compressed air inflation, and detailed models of packer components were also researched.

Blue Ice Drill (BID)
Maintenance and upgrade tasks were largely completed during the quarter for the BID-1. The drill was subsequently cleaned, packed and shipped for the upcoming Law Dome project in Antarctica. IDDO continued communication with BID tent vendor Fabricon. Engineer Tanner Kuhl visited the vendor's location in mid-July to review the design and progress thus far, and the tent was completed in mid-August.

Thermal Drill
The Engineering Requirements document for the Thermal Drill was approved and released. IDDO engineers worked to identify, procure and test some thermal and power limiting materials and components during the quarter. New heat rings were specified, as the old model is now out of production, and a number of new rings were ordered late in the quarter.

Hand Augers
Planned modifications for the cleat and locking break components of the SideWinder units were implemented on all five kits in inventory. Equipment was returned from Svalbard and Greenland and was repaired as needed. Orders were subsequently placed for replacement of a few components that were stuck in the ice during the 2018 Arctic fieldwork.

4-Inch Drills
Maintenance was completed for the 4-Inch Drill system that returned from Antarctica. One core barrel set was modified to match beneficial modifications made to another barrel set in inventory. An improved cable keeper for the crown sheave was designed, fabricated and implemented.

Eclipse Drills
A more robust top cover and new side panels were installed on the Eclipse Drill traversing system. Beneficial updates were made to the Operator's Manual. Small tools such as strap wrenches and sharpening stones were purchased for use in the field.

Foro 3000 Drill
IDDO continued initial development tasks for the Foro 3000 Drill system during the second quarter. Modifications were made to the Intermediate Depth Drill cutter head design that may make it possible to perform multiple core breaks during one drill run. This will be of value when drilling brittle ice with the Foro 3000 Drill. Detailed design of the winch drum was also initiated during the quarter.

Foro Drill
Fabrication of the Foro Drill core barrels was completed and all parts for the anti-torque and motor sections were ordered except for the actual drill motors for which IDDO expects to pursue quotes in the third quarter. The magnetic slide hammers were assembled, and load testing of the sled and hitch was completed. Shipping cases for the sondes, tower, and winch were also ordered.

Rapid Air Movement (RAM) Drill
Acceleration of RAM Drill design and procurement tasks continued to accommodate a potential test of the system in Greenland during summer 2018. All major component orders have been placed and electrical testing of the sonde was initiated. Initial testing for air pressure losses was completed.

Thermal Drill
Updated science requirements for IDDO's Thermal Drill were finalized at the end of February. A thermal or power limiting feature is being planned as part of the system upgrades, to help prevent premature heat ring failure. A benchtop testing procedure was initiated during the quarter and a number of thermal/power limiting options are under consideration. A manufacturer of suitable heat ring elements has been identified, and a core removal tool was designed and built making use of magnets to disengage the core dogs.

Intermediate Depth Drill (IDD)
The new 1650-meter long winch cable was spooled on the winch drum and was terminated, and the level wind controls were modified to work with the current emergency-stop system. Acceptance testing and troubleshooting of the Mage control system components continued. At the end of the quarter, the IDD's control system components were shipped back to Mage for further tuning.

Winkie Drill
IDDO is pursuing upgrades to integrate borehole casing with the current Winkie Drill system for a planned Thwaites Glacier project. Technology from the rock drilling industry and international ice drilling community is being researched.

Blue Ice Drill (BID)
Redesigned components for the BID tripod feet were received and installed during the quarter. A custom tent enclosure manufacturer was identified in April, and design of a tent and its integration with the BID tripod system has been initiated.

In summer 2017, IDDO worked to begin fabrication of a second BID-Deep system (for wide-diameter ice coring to 200 meters), based on user demand and per a directive in the IDPO Long Range Science Plan 2016-2026. Fabrication of the second system was initially scheduled for completion in Program Year (PY) 2018. However, there is no longer a funded science project this year that requires a second BID-Deep system, and therefore completion of the second BID-Deep system has been postponed to enable work on higher-priority projects in PY 2018.

Foro 700 Drill
The IDPO Science Advisory Board identified in the IDPO Long Range Science Plan 2015-2025 a priority need to alter the surface equipment for the existing Intermediate Depth Drill to make a drilling operation that is less logistically intensive, to be used for ice coring at sites with limited logistics and with two months or less time on site. From discussions organized by IDPO with iterative discussions between IDPO, scientists, and IDDO staff, the science requirements for a 'Foro 700 Drill' were completed during the second quarter. The next step is to develop the conceptual design for the drill, which could possibly happen in PY 2019 pending availability of funds and project prioritization.

Foro 3000 Drill
IDDO kicked off development of the Foro 3000 Drill system during the first quarter. The Foro 3000 concept builds on the Intermediate Depth Drill (IDD) system and will allow for deep coring down to 3000 meters depth. A detailed task list was developed and other important documentation such as the Project Management Plan and the Engineering Requirements were completed and formally released. Detailed design work was completed for updates to the IDD's anti-torque components to allow for accommodation of a larger-diameter cable. The IDD sonde design was also modified to allow for recovery of 3-meter long cores per drill run.

Foro Drill
Several Foro Drill components were received that were ordered in late PY 2017, including a spare winch gearbox, winch motor, load pin and tower tubing. Control box functionality testing was initiated. The sonde design is now finalized and fabrication has begun.

Rapid Air Movement (RAM) Drill
Design and procurement tasks were accelerated to accommodate a potential test of the Rapid Air Movement (RAM) Drill system in Greenland during summer 2018. Component purchases included a new hose reel and downhole motors and controllers. Initial subsystem testing has begun.

Thermal Drill
IDDO engineers researched potential vendors for new heat rings, as the former model is now out of production. IDDO also worked with IDPO and community scientists (Rick Forster, Lora Koenig, Peter Neff, Eric Steig) to iterate on a Science Requirements document before planned modifications are made to extend the Thermal Drill's depth capability to 300 meters, as is called for in the Long Range Science Plan.

Intermediate Depth Drill
Many Intermediate Depth Drill components ordered in late PY 2017 were received, including a spare winch gearbox, spare levelwind rollers, borehole pressure sensors, load pins with internal amplifiers, and the long-awaited Mage control system components.
