APPARATUS AND METHOD FOR ASSEMBLING AND SERVICING UNDERWATER POWER STATIONS

摘要

The invention relates to a method for carrying out a service measure for an underwater power station comprising a machine gondola with a water turbine that rotates thereon. Said method encompasses the following steps: the machine gondola including the water turbine is hoisted above the water surface by means of a supporting frame which is disposed outboard on a watercraft and can be lowered to the place of installation of the underwater power station by means of a control cable system on booms projecting from the side of the watercraft; bulky components of the machine gondola are dismounted on the supporting frame; the partially dismounted machine gondola is transferred from the supporting frame to the watercraft in order to be further handled by a supporting device which can be moved along the deck of the watercraft by means of a guide rail system.
