Abstract [en]

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.

The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.

The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel. Without a frequency converter the installation costs for shoreside electricity is less expensive since the frequency converter corresponds to approximately 70 % of all the installation costs.

By connecting only a few vessels with long visiting time in port tons of pollution can be reduced when the shoreside electricity is generated from renewable sources. Even with electricity generated partly from fossil fuel over 90 % of the pollutions can be reduced by using shoreside electricity.
