1. Navigating Sustainability : A case study exploring alternative energy sources for maritime shipping
University essay from KTH/Industriell ekonomi och organisation (Inst.)Abstract : This master thesis studies alternative energy sources for maritime shipping in Sweden. With current climate goals, and a need for change, the maritime sector currently undergoes intense transitions. For shipping companies to lower their carbon footprint, the need to replace non decarbonised fuels is hence critical. READ MORE

3. Resonance Mitigation in the Attitude Control of a Flexible Large Solar Sail
University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikAbstract : This project is about the design process of a resonancemitigating algorithm for a large solar sail. The solar sail isa structure made up by four long booms in a cross patternwith suspended sails between the edges of the booms. Thespacecraft in this report is controlled using smaller rotatingsails at each tip of the booms. READ MORE

5. Comparison of Achieved Fuel Savings on Ships by Different Wind Propulsion Systems Using a 3-DoF Resistance Model
University essay from KTH/Marina systemAbstract : This thesis aims to determine how different wind propulsion systems should be sized in order to achieve comparable fuel savings. The selected wind propulsion systems for the comparison are Dynarig, rigid wing sail and rotor sail. To answer this question, a performance prediction program based on a 3 Degree of Freedom resistance model was developed. READ MORE
