The ship's power plant consists of three main parts: the main power plant, the auxiliary power plant and other auxiliary machinery and equipment.
The main power unit, also known as the propulsion unit, is a set of mechanical equipment that provides the ship's propulsion power and ensures that the ship moves at a certain speed , including the main engine and its auxiliaries. equipment and forms the heart of the entire ship. The main power device includes the main engine, transmission equipment, shaft system, propeller, etc. When the main engine starts, the transmission equipment and shaft system can be driven to operate the propeller. When a propeller, usually a propeller, turns in the water, it moves the ship forward or backward.
An auxiliary power unit is a device used toprovide various energies other than propulsion devices for the navigational, operational and life needs of the vessel, including devices that provide electricity, lighting and other sources of energy for the entire ship, such as electricity production. Units, auxiliary boilers, etc.
Stavanger in Norway has become more and more famous recently, and many people go there not because of the picturesque landscape, but because of the new wind turbine "Hywind" which is built there.
It is said that this wind turbine does not have "roots" in the sea. In other words, it is the world's first wind turbine floating on the sea. This means that at In the future, it might be able to provide power to deep-sea ships or submarines.
Like a beauty on the water
Mr. Stan Johannes, a Statoil staff member, said Hywind fans are made of much the same materialsials than land fans; that, Its underwater part is installed on a buoy of more than 100 meters and is fixed at a depth of 120 to 700 meters under the sea thanks to three anchor cables so that it can move with the wind and the waves and generate electricity in the wind.
The generator blades of this wind turbine measure 80 meters in diameter and are located approximately 65 meters above sea level. When it was built, it was not assembled on land and then installed at sea, but was built and assembled bit by bit at sea using a crane on the ship, and adjusted over time according to the actual situation.
The key technology is to make it as thin as possible and remove the "fat" so that it can remain relatively stable at sea and improve its power generation capacity, while making it strong enough to withstand bad weather. at sea. . In addition, the generator frame terrestre was originally in the upper part. You now have to move the chassis downwards, which increases the technical difficulty.
