The Swedish Maritime Administration (SMA) is responsible for the Swedish icebreaking service and has conducted a pre-study on how the current icebreakers can be replaced. SSPA has supported SMA with investigations of different aspects, including forecast of future tonnage in the Gulf of Bothnia, evaluation of alternative fuels, alternatives for hybrid solutions, evaluation of different propulsion concepts and overall feasibility studies of different options’ capabilities. The results of these analysis are tools for decision-making. To support the decisions in an economic perspective, the life cycle costs of different key features were assessed.
