Offshore and subsea applications require solutions for the most extreme operating conditions.

The products of ANDRITZ HYDRO fulfill the demanding requirements placed by customers and certification authorities in the hydropower energy, oil, and gas industries all over the world. Depending on the industry concerned, several offshore products and solutions are available, as follows:

Offshore hydropower energy production

Tidal current turbines operate according to the same principle as a horizontal axis wind turbine. The tidal current creates a torque on the rotor which is used to drive a step-up gearbox, and this in turn drives the asynchronous generator. Power quality is controlled by power electronics.

Sea water lift applications

Thanks to their design, submersible motor pumps create an extremely valuable commodity on platforms everywhere. The high-tech units can be completely submerged in the sea water, with the advantage that no pump room is required to install the pumps. They are absolutely maintenance-free and can be installed easily and flexibly without any limitations on depths.
