Project Information
The main objective of this project is the development of mathematical models to determine the causes of increased power requirements of ships under realistic operational conditions. This involves the quantitative determination of the individual contributions, such as waves, shallow water, and wind. Long-term full-scale measurements onboard a 14,000 TEU container ship are performed. For the development, validation and application of the mathematical models, and measured data are used. Simplified models are derived based on measured and published data. Furthermore, methods to check the validity and plausibility of the measured data are developed. Finally, routing assistance systems are developed that provide optimized nautical parameters to the ship's command.

Project Information
Short sea shipping plays an important role in the transport chain of sea freight. The main objective of this project is the development of mathematical models to quantify the power requirements of coastal ships as well as the development of a routing assistance system. The effects of differences between the targeted and the actual geometry are taken into account in the development of these mathematical models. A separate mathematical model is to be developed for the change in resistance due to fouling, which can be used to determine optimal hull surface cleaning intervals. Long-term full-scale measurements onboard are performed. Furthermore, extensive CFD simulations will be performed.

Universität Duisburg-Essen
Project Information
This project deals with developing and building a zero-emission and autonomous research ship. The research ship with a length of about 15 m is equipped with all the technical components necessary for remote control and complete automation. Furthermore, she is equipped with an electric main propulsion system, so that various energy converters can be used. All systems on board are modular in terms of hardware and software and can, therefore, be replaced if necessary.

Project Information
Inland waterway vessels are cost-effective and environmentally-friendly compared to other means of transport in terms of transport performance. However, due to the frequent occurrence of long-lasting shallow water periods, the transport of goods on inland waterways had to be reduced significantly. When water levels drop, it seems obvious to adapt the ships to the changing environmental conditions. As part of the FlaBi project, propulsion concepts are developed that are particularly suitable for operating under extreme shallow water conditions. Furthermore, concepts for retrofitting inland waterway vessels for navigation at extremely low water levels are developed and validated. This includes measures to increase the ship’s displacement at very shallow drafts and the development of a retrofit concept for a secondary propulsion system.
Development of a method to calculate inland waterway emissions (Binem)

Project Partner:
- Bundesanstalt für Wasserbau
Project Informationen
The aim of this Binem project is to develop and validate a method for calculating emissions caused by inland waterway vessels. The method has a modular structure. Depending on the kind of vessel and the associated nautical and environmental data, resistance and power are calculated. Emissions are then determined based on specific fuel consumption data and emission factors. To validate the process, measurements of the emissions on board of ships are used.

Project Information
The project deals with the hydrodynamic shape optimization of different kinds of ships under near-operational conditions. Various optimization algorithms are used for this purpose. To predict a ship’s required power, boundary element methods based on potential theory as well as Reynolds-averaged Navier-Stokes solvers are used. Hydrodynamic optimization is to be carried out under calm water conditions and in waves.
