Digital twin for ship behavior and response in ice operation

In this position you need to develop a digital twin of a ship operating in ice infested waters. You will use existing numerical model, which you will improve and validate using experimental ice-structure interaction data gathered on a real ship. The experimental data involves ship motion and performance data, strain gage data, and ice conditions information (visual observation together with camera-based identification system). Therefore, you must come up with a working solution that can integrate observational measured data (with different sampling frequencies) into a simulation environment. At first, this simulation environment will be Abaqus. This integration is referred to as digital twin framework. As part of this framework development, the research should quantify the uncertainties and relevant simplifications, which would enable fast model development (real-to-digital) and accurate ice-structure interaction simulations. There are two goals in this work. Short term goal is to develop realistic structural analysis model, while long term goals is to reach a reduced order model (ROM) that is deployable in a DSS (decision support system).

Requirements

The performed work combines computational and experimental research with system engineering. The applicant should have good understanding in either one of those topics: ice mechanics, solid mechanics, modeling, data handling/flow between systems. The candidate should prove his/her capabilities in writing the technical report and scientific papers in high quality journals. Good skills in English, writing and oral, are required. Experience in collaborative research/publication with the existing TalTech staff is also a plus. The applicant for the position must have a Master’s degree and must fulfill the requirements for doctoral students at the Tallinn University of Technology (https://taltech.ee/en/phd-admission). During the assessment emphasis will be put on your potential for research, motivation, and personal suitability for the position.

Employment & Funding:

The position is at the Tallinn University of Technology and includes some work as a teaching assistant in our courses. The expected duration of doctoral studies is four years, but following a standard practice the contract is first made for 4 months. The
extension is subject to the advance of studies and research. The base salary is according to the salary system of Tallinn University of Technology, but flexible depending on the
candidates capabilities.
