A method and an assembly/disassembly arrangement for a tunnel thruster unit includes a thruster unit and a tunnel, a first attachment arrangement for fitting of said thruster unit to the tunnel and at least one further attachment arrangement for safe fitting of the thruster unit in the tunnel. A further attachment arrangement is in the form of a first interface device fixedly attached to and protruding from attached to the inside of the tunnel wall and a second interface device fixedly attached to the thruster unit.

Method and arrangement for attachment and/or disassembly/assembly of a tunnel thruster

The present invention relates to a method and an auxiliary device in connection with disassembly and/or assembly of a tunnel thruster unit by use of the auxiliary device () to guide the thruster unit () and its movement during disassembly/assembly inside the tunnel (), the thruster unit () thereafter being led away through the tunnel (), said auxiliary device () being removably fixed at the thruster unit () before final disassembly, such that the auxiliary device () controls the movement during disassembly/assembly, mainly by compressive forces.
