Patent ID: 8692403

Claim:
An installation method for an underwater power plant having: a nacelle comprising a nacelle housing having a first nacelle housing section with bearings; a water turbine including a drive connection to a drive shaft, the drive shaft being mounted inside the first nacelle housing section and the drive shaft is carried by the bearings; an electrical generator, comprising a generator rotor and a generator stator; and a generator housing; wherein the electrical generator and the generator housing form a separate generator module that is handled and installed as a whole, and wherein an adjustment of the bearings within the first nacelle housing section for the drive shaft is executed before a production of a coupling between the generator module and the drive shaft, and wherein the generator housing of the generator module is coupled in a rotationally-fixed manner to the first nacelle housing section and the generator rotor is coupled in a rotationally-fixed manner to the drive shaft, wherein the generator rotor is carried by the drive shaft after the coupling such that the bearings within the first nacelle housing section are the only bearings of the generator rotor.
