Pitch on the safe side

Proven IMO designed technology
for more than 25 years –
8 years successfully in tidal stream systems.


IMO bearings

…as blade bearings for marine current systems and wave power.

Tidal Energy

As this way of energy exploitation is continually working – independently from weather conditions – the system and consequently bearing is under load 24/7.

  • energy from marine current systems is highly predictable
  • tidal turbines generate electricity from the sea autonomously
  • twin axial flow rotors drive generators via a gearbox
  • two or three blade rotors are adjusted by a triple row IMO roller bearing

Focus on research & development

Focus on research & development

Applying German engineering expertise, IMO designs slewing rings for tidal energy installations using FE models and test rigs to verify bearing seal under pressure.

IMO is certified according to the standards ISO 9001, ISO 14001 and OHSAS 18001. and follows the technical guidelines set by leading certifying authorities when calculating the slewing ring performance and life capabilities.


The video

Here you can see the operating principle of the SeaGen Turbines.

The IMO bearings pitch the rotor blades in water dephts of around 30 m – 24 hours, 7 days a week.
