Abstract

A method for repairing an ice of an ice field comprising drilling, by an ice repairing apparatus, at least one hole to the ice of the ice field to remove, at least partly, a damaged ice, providing a solid ice insert having substantially the same size as the at least one hole, and inserting the ice insert into the at least hole such that a top surface of the ice insert is substantially on the same level with a surface of the ice of the ice field. An ice repairing apparatus comprising a rotating blade configured to drill a hole to an ice of an ice field, a rotating shaft configured to rotate the blade, wherein the shaft comprises a first end coupled with the blade, and a second end configured to be coupled with a power source for rotating the shaft; and a limiter coupled with the shaft configured to set against a surface of the ice and to prevent drilling of the blade into the ice when a desired depth of the hole is achieved. An ice repairing arrangement comprising an ice repairing apparatus, a mould for producing at least one ice insert, and freezer configured to freeze and/or to keep frozen at least one ice insert.
