1. Probabilistic Added Wave Resistance Predictions for Design of RoPax Ferries
University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikAbstract : This thesis investigates reasons for significant uncertainties in added wave resistance predictionsand how wave conditions can potentially affect the design of RoPax ferries. The objectiveis to find a suitable prediction method of added wave resistance for the RoPax ferry designapplication. READ MORE

2. Efficient seakeeping performance predictions with CFD
University essay from KTH/Marina systemAbstract : With steadily increasing computational power, computational fluid dynamics (CFD) can be applied to unsteady problems such as seakeeping simulations. Therefore, a good balance between accuracy and computational speed is required. READ MORE

3. Parametric Hull Form Variation and Assessment of Seakeeping Performance
University essay from KTH/Marina systemAbstract : This Master Thesis is about the assessment of the seakeeping performance of different ships subjected to hull parametric variations. The latest version of the potential flow CFD software Shipflow in combination with a CAD platform (CAESES) have been used to carry out the evaluations. READ MORE

4. Comparison of Idealized 1D and Forecast 2D Wave Spectra in Ship Response Predictions
University essay from KTH/Marina systemAbstract : Commonly, when calculating ship responses one uses idealized wave spectra to represent the sea. In the idealized model, the sea is frequently assumed to consist of swell and windwaves, which are usually represented by idealized 1D wave spectra, and the directionality of wind-waves is accounted for by multiplication with a standard spreading function.

5. Determining the pressure distribution on submerged 2D bodies using dissipative potential flow.
University essay from KTH/Marina systemAbstract : Globalization is reaching the furthest corners of the world and with globalizations comes a rising demand on transportation. In shipping; a significant cost both to the ship owners and the environment are the fossil fuels used for propulsion, even a small reduction in the wave resistance can bring considerable reductions both in operating costs and emissions for such ships.
