Master thesis projects
Together with Chalmers University Technology, SSPA announces two proposals of Master thesis projects. The current thesis projects that are available are “High-performance sailing: Fluid Structure Interaction of hydrofoils” and “CFD modelling of floating object’s motion decay”. The projects start in January 2021.
High-performance sailing: Fluid Structure Interaction of hydrofoils
With the advent of foiling in the America’s Cup in 2013 and the subsequent interest in foiling, the future of high-performance sailing is pending toward a large portion of foiling boats being sailed and built. The use of composite manufacturing and light-weight structures implies that significant deformations of the hydrofoils are present in all sailing scenarios, leaving the designers to investigate not only the hydrodynamic forces from the shape of the foil, but also its Fluid Structure Interaction (FSI) behaviour. The deflection and twists of the hydrofoils under fluid loads will ultimately affect the stability of the whole boat with implications in the overall speed and crew-safety.
The supervisory team composed of Arash Eslamdoost (Associate Professor –supervisor and examiner, department of Mechanics and Maritime Sciences, Chalmers University of Technology) and Laura Marimon Giovannetti (co-supervisor from SSPA) will provide some real-sailing scenarios and loading cases with the expertise from Laura of high-performance sailing both from an engineering and from a sailing perspective. Dr Alex A. Shiri (co-supervisor from SSPA).
CFD modelling of floating object’s motion decay
Ocean wave as a renewable energy source is accessible in many parts of the world. Design of a power take-off (PTO) unit for a wave energy convertor depends on the knowledge of interaction between water surface and solid object. Study of slamming loads and motion of floating object in waves are important both from structural design point of view and from fluid-structure interaction. There are many numerical tools available to simulate the motion of a vessel in water, but the accuracy of simulations and cost of the calculations are always two important factors for the design process. Evaluation of the numerical models against the experimental data is the focus of this study.
The supervisory team composed of Dr Alex A. Shiri (supervisor from SSPA), Carl-Erik Janson (Professor – supervisor, department of Mechanics and Maritime Sciences, Chalmers University of Technology) and Dr Laura Marimon Giovannetti (co-supervisor from SSPA) will provide experimental scenarios, cases of generic bodies and CFD methods to simulate the motion of object.

Innovations for wind ship propulsion, online conference
The latest scientific and technological research in the field of sailing will be presented on the international conference INNOV’SAIL 2020 in June. Chalmers University of Technology hosts the conference and SSPA is one of the co-organizers. Sailing shall not only be associated with racing and recreation. Sailing in commercial shipping is on its way back. SSPA is conducting extensive research and are contributing with the latest findings and will present several papers.
Master Thesis
If you are enrolled at a Swedish technical university and would like to carry out your Master Thesis project at SSPA, please send us an application before 15 November. We will admit 1-2 thesis projects per year, preferably with two students per project. You will work at SSPA’s office in Gothenburg or Stockholm and be supervised by our researchers. Note that you will not be an employee during the thesis work.
Challenging applications in marine engineering
Marine 2019 was recently hosted by Chalmers University of Technology in Gothenburg, Sweden. This conference is a meeting place for researchers developing computational methods and scientists and engineers focusing on challenging applications in marine engineering. Researchers from SSPA, together with some of our research partners, presented interesting papers.
Sailing, aerodynamics in waves
Prediction and analysis of added hydrodynamic resistance in waves is an established research topic, with several accepted methods, but the study of sail aerodynamics in waves is an open research area. SSPA and Chalmers are cooperating in the Sports & Technology initiative, with several research projects in sailing. The leading journal Ocean Engineering has recently published a paper titled “CFD prediction of steady and unsteady upwind sail aerodynamics”.
