Commercial load flow in the world; sea transportation and air transport.
90% of this freight transport is done through the seas and oceans. Sea transportation, on the other hand, has serious pollution problems. This pollution, which you can call ship emissions, is defined as polluting gas coming out of the ship's chimney.
These polluting gases can be listed as nitrogenoxide, sulpoxide, carbon dioxide, carbon monoxide, unspent hydrocarbons and particles. In addition, diesel fuels used in ships create more sulfur and particulate matter than other fuels.
For example, if you want to create The 15 largest container ships emit emissions emitted by cars around the world. This emanating from almost 760 cars is equal to emissions.
The ships' emissions cause significant pollution in the area where they are located.

Apart from the pollution that occurs at the entrances and exits of the ships, the ports are also grappling with the pollution caused by the ships during the time they wait at the port. The reason for this dirt is that the ships provide their energy needs from diesel fuels, even if they are in port.
Therefore, the solution in the European Union; to meet the energy needs of the ships docking at the port by land. As far as we know, a standard is being prepared for this.
Apart from all this, it is important to look at the event economically; The cost of diesel used due to oil prices in Turkey is increasing day by day.
The system is expected to pay itself off after approximately two years, compared to the total costs incurs if the ship is fed from the mains or fed from the diesel generator during its time at the port ( including the installation costs of the Shore Connection system).
The method used in my day is; as soon as the ship docks, it is powered by diesel generators. The technology needed to disable the diesel generator and connect the ship to the grid is rapidly evolving. Let's briefly describe this method known as "Shore Connection" in the following table.
Energy from the grid after the Medium Voltage Distribution system, the frequency from 50Hz to 60 Hz to reduce the voltage is necessary for the compensents of a ready-made system shorebox'a an under ground cable. He then logs into the ship to synchronize with the generator system inside the ship.
This system, which we have roughly described, will allow ships to feed from the city grid by land instead of inginging energy with a diesel generator as soon as they dock.
As I mentioned earlier, dirt caused by ships in the port will be minimized. It is predicted that this system, which has no examples yet in Turkey, will spread rapidly in the coming years.
