Patent number: 11530574Abstract: A method is for generating a freeroom for a mast element in a ground. The method includes the steps: a) drilling a first annular recess into the ground, the first recess having: a first diameter; and a first depth; b) drilling a second annular recess in the ground, the second recess being arranged to receive the mast element, and the second recess: having a diameter which is smaller than the first diameter; having a second depth which is larger than the first depth; surrounding a first core of the ground; and being surrounded by the first recess; wherein there is, defined between the first recess and the second recess, a second core which can be removed to generate a freeroom.Type: GrantFiled: November 7, 2018Date of Patent: December 20, 2022Assignee: Comrod ASInventor: Ole Gunnar Fjelde

Patent number: 11505996Abstract: A system and a method are for positioning a drilling rig arranged to drill in a ground. The system has a positioning jig including at least one coupling portion; a drilling rig including at least two coupling portions; and at least two anchoring elements including an upper coupling portion and a lower coupling portion. The lower coupling portion of the anchoring element is arranged to be releasably fixed to the ground. The upper coupling portion of the anchoring element is arranged to be connected to the coupling portion of the positioning jig and to the coupling portion of the drilling rig, so that the upper coupling portion of the anchoring element can optionally be connected to the positioning jig or the drilling rig.Type: GrantFiled: November 16, 2018Date of Patent: November 22, 2022Assignee: Comrod ASInventor: Ole Gunnar Fjelde
