DEVICE AND METHOD FOR APPLYING A SECONDARY CONSTRUCTION TO AN OFFSHORE PRIMARY CONSTRUCTION

摘要

An auxiliary device is described for mounting and securing a secondary structure to an already existing offshore primary structure in a desired position. The auxiliary device comprises a support body which can be suspended by means of coupling means from a hoisting means and which can be brought in the vicinity of the primary construction. The supporting body is furthermore provided with remotely controllable tools, wherein a tool is adapted to engage and release the secondary structure in the desired position and / or to connect the secondary structure electrically and / or mechanically to the primary structure. A corresponding method is also described. The device and method are particularly suitable for accurately mounting an anode cage around a monopole foundation of an offshore wind turbine, for positioning and for electrically and / or mechanically connecting the secondary structure to the primary structure.
