Abstract: A method for installing a machine monitoring device which includes at least one gateway, at least one machine operation data sensor unit, a transmission unit having a transmission antenna for radio-based transfer of the machine operation data from the sensor unit to the gateway, and at least one user terminal for communication with the gateway. The antenna position is variable relative to the sensor and/or transmission units. The method steps include installing the gateway; establishing a communication link between the transmission unit and the gateway, positioning the transmission unit and antenna at or near the machine, transferring data packets to determine at least one communication parameter influencing the communication transfer quality, generating a position change instruction for the transmission unit or antenna and/or an action recommendation on the basis of the communication parameter, and displaying the instruction and/or recommendation at a user terminal.

Abstract: An energy generating unit especially for installation on a bed of a stream of water or floating in the water, composed of a plurality of components, such as an inlet housing, a turbine housing, a drive unit arranged in the turbine housing, and a downstream draft tube, in which at least one component is provided with remotely operable connectors and with guides so as to be separable from at least one other component while in the water such that the at least one component, such as the drive unit, can be removed from the water for maintenance while the at least one other component, such as the draft tube, remains in the water, as well as a method for maintaining such an energy generating unit by selectively removing at least one component from the water while at least one other component remains in the water.
