Abstract (en)
[origin: WO2010020215A2] The invention relates to a drilling rig that is provided for mounting on a drilling platform, comprising a drilling mast having at least two segments and a feed carriage, said drilling mast being built in such a manner that at least one segment is displaced in an upward manner by means of the feed carriage. The invention also relates to a mounting method for a drilling mast having at least two segments, consisting of the following steps: a feed carriage is fixed, a mast segment is provided below the feed carriage and said mast segment is displaced in an upward manner by the feed carriage. Due to this, additional auxiliary devices for building the drilling mast are not required thus saving space.
