Multi-Horizon Prediction of Power Consumption during Dynamic Positioning Operations: Physical, Data-Driven and Hybrid Model Approaches

A significant decrease in greenhouse gas emissions can be achieved by including a prediction of future power consumption in the control of ships’ power plants during transits. Moreover, including a prediction of power consumption in the Energy Management System (EMS) during Dynamic Positioning (DP) operations can also contribute to a reduction...

Load Cycle Assessment for Maritime Batteries: with Diverse Operational Profile

Increasing emissions have led to the search for alternate power systems to provide energy for maritime applications. The recent drop in battery prices (over 200 % in the last ten years) has made battery energy storage one of the practical alternatives for fossil fuels to curb emissions and reduce the carbon footprint of the maritime sector. The...

Impact of SOFC Power Generation Plant on Carbon Intensity Index (CII) Calculation for Cruise Ships

The International Maritime Organization (IMO) has recently discussed the introduction of a new design index called the Carbon Intensity Indicator (CII), which is a measure of the total carbon dioxide emissions divided by the amount of cargo carried and by the distance travelled on a one-year basis. In this study, authors have analysed a cruise...

Determining water speed of ships: Establishing the delivered power needed as a function of the ship's speed in relation to the water

In this thesis, we look at the traditional way of calculating a ship’s Power-Speed function using the Iterative Method, and then compare this to the renewed method created by Michaël Mersie, called the Direct Method. We find that, only under very specific circumstances, the Iterative Method can be slightly better at estimating the function of...
