How does Underwater Turbine work?

We have mentioned how the underwater turbine works. Read the article and get to know about it.

The global climate change influences all our search for different discharge free energy generation which leads us to a huge future of the oceans. Before, the seas of the world hold enormous energy and utilize for example in the tidal streams. Hydro develops the turbine for the utilization of these tidal currents with which this wide energy change into electric power. According to expert opinion, roughly 400 terawatt-hours per year can be won in this way from the seas of the world. 

The dimensions of the tidal present turbine are impressive. The turbine nacelle is almost 13 meters long. The rotor has a diameter of 16 meters in total the plant is 26 meters high which amounts to the size of a seven-story house. Before, the installation vessel reaches the intended location for the underwater generating station. 


The turbine connects to a pre-placed undersea cable for the future recovery of the turbine. The conservation causes guide bonds fixes to the base. The entire unit now can be submerged after the underwater power station reaches the ocean floor, the turbine starts from the onshore control room. The sea current sets the rotor into motion. However, the turbine begins to supply electricity with a generation design following because the tides are regularly, predictably and reliably. 

Each turbine has an put the power of 1 megawatt. The tides change their direction of flow roughly in 6 hours. The special rotor design of the turbine allows the flow of consumption from both ends without adjusting the turbine. The rotor simply changes its direction of turning which means, there is no complex appliances require for blade accommodation or nacelle rotation.

The making of the underwater turbine includes:

  • Special attention is given to simply hygienic and eco-friendliness.
  • The design removes failure-prone communication and works without oils and grease.
  • Seawater is for grease job and therefore special quality lies in the delay of complex and sensitive seals.
  • This has been achieved by designing the engine to operate submerged in seawater through the sea cable, the generated electricity. Directly passed to the onshore inverter stations.
