Foro 1650 Drill

Description

In PY 2014, IDP completed the design and fabrication of a Foro 1650 Drill (previously referred to as the Intermediate Depth Drill or IDD). With assistance from international colleagues, IDP modified the existing design of the Hans Tausen Drill and built a new system. The system was field-tested outside of Summit Station, Greenland, in spring 2014 and was used in the successful completion of the SPICEcore project near South Pole Station from 2014-2016, where a total of 1,751 m of core was collected. The drill was originally designed to reach a depth of 1,500 m. Following a post-project analysis of the SPICEcore project, IDP has set the cable limit for the current winch drum at 1,700 m capacity, which allows for drilling to approximately 1,650 m depth. This maintains adequate safety margins for the drum flanges and mitigates the risk of system damage should the level wind not spool the cable perfectly every time. While the system was originally called the Intermediate Depth Drill or IDD, the name was updated in 2019 to signify the shared sonde design of other IDP drill systems (e.g. Foro 400, Foro 3000). IDP also procured new 4-conductor cables following the SPICEcore project to mitigate operational issues experienced during the project. IDP also pursued a resign of the drill system electronics to implement beneficial sensors for temperature, pressure, and inclination. The drill system electronics design is now shared between the Foro 1650 and the Foro 3000, making use of proven, off-the-shelf parts wherever possible.
