In september 2023, the European Commission adopted a regulation on the use of renewable
and low-carbon fuels in maritime transport and the establishment of alternative fuels. Member
states are required to ensure a minimum supply of shore-side electricity for cruise and container
ships in ports by the end of 2029. Electrification of ports will be crucial fort he transition to a
low-carbon society, but it requires significant changes to existing power grids. Consequently,
it is clear that the European Union will need to formulate appropriate regulations and incentive
measuers to support these projects.
To comply with the new regulation and the need for greater connection power, a project is being
prepared in the port to connect ships to the shore power grid. This would reduce emissions in
ports and support the green transition of shipping companies.
Throughout the year, many ships arrive at the port, which will be powered from the shore in the
future, but cruise ships are the largest consumers among them. For this reason, the thesis focuses
on these, as their average consumption can reach up to 20 MW of connection power.
The purpose of the thesis is to show the impact of cruise ships on the port's electricity
consumption. Using a model, I will predict the consumption and peak power of different cruise
ships, enabling the port to provide sufficent energy upon connection.
I achived the desired results using K-means clustering and the elbow and silhoutette methods.
The MATLAB program divided the data into the desired number of profiles using the K-means
algorithm, allowing me to identify typical consumption profiles for the port and ships.
I compared the results and added the ship consumtion to the already known port consumption.
I analyzed the consumption in two scenarios: hot summer days and cloudy cooler days. This
confirmed my hypothesis that cruise ships will have different impacts on port consumption
depending on their size and arrival time. The largest consumption will be contributed by large
cruise ships on sunny days, when it can be up to 12 times grater.
