The RUBIN Alliance “Emission-free electrified maritime urban transport” - in short E2MUT aims to create “Green energies for blue transportation.” The aim of the alliance is to promote the development and market introduction of emission-free urban mobility solutions on the water.
A special focus is on the “urban” sector, i.e. transport within cities and between neighbouring cities and residential areas. Increasing urbanisation and individual traffic are leading to congested roads in urban areas. This trend must be countered by integrating waterways and, in the process, eliminating a large part of the pollutant and noise emissions through emission-free propulsion systems based on batteries and hydrogen.
The project partners
This research project is an alliance of 14 partners: 12 industry companies, nine of which are SMEs, and two research institutions. The majority of the German alliance partners are concentrated in the Rostock area. In addition, there is one partner each from Stralsund, Hamburg (ar engineers) and Munich. The alliance thus represents a broad, competence spectrum of the maritime industry and environmentally friendly propulsion systems for maritime applications.
Successful implementation of emission-free electromobility requires an integrated interdisciplinary approach to the development of innovative solutions. To this end, the E2MUT research project as a system is divided into three fields of competence:
- Mobility and infrastructure
- Propulsion systems and energy supply
- Electric vessels
In the electric vessel field, ar engineers GmbH is researching the applicability of adaptive and instrumented CFRP foils for the continuous reduction of hull resistance.
In shipbuilding, hydrofoils are connected to the hull underwater and generate a dynamic lift at increasing speed, which lifts the hull out of the water. This additional lift enables the vessel to operate much more efficiently at higher speeds.
The instrumentation of the foils aims to collect dedicated input data for future development projects to enable long-term optimisation of foil structures and continuous structural monitoring.
The following competences at ar engineers are being used and further developed in this research project:
- Conceptual design and development of foil systems for hydrofoils
- CAD design of high-performance lightweight structures
- Design, calculation and optimisation of highly stressed composite structures using Ansys software
- Development of an algorithm for the calculation of hydrodynamic loads of hydrofoils using the Python programming language
- Development of algorithms for continuous structural monitoring of sensor-integrated composite components
Our holistic view of the project means we see where the potential of lightweight design or component optimisation can be realised and also ensures the best possible coordination of the project partners. Through the adept use and further development of tools and methods we are able to make an important contribution to achieving the project’s objectives.

Claas‘ favorite project:
I like being part of finding solutions for sustainable mobility concepts.
The participation of ar engineers in the research project E2MUT (emission-free electrified maritime urban transport) enables us young engineers to conduct research in the field of climate-neutral mobility concepts and to become part of finding solutions so that we will not have to do without this mobility, which is so important for all of us, and the freedom and autonomy it brings in the future.
Through close cooperation with regional partners such as the Fraunhofer Institute for Large Structures in Production Engineering IGP, Tamsen Maritim GmbH and torqeedo GmbH, E2MUT creates the basis for using the skills learned and partnerships established in the project beyond the project itself. Our goal is that the regional market-ready development and production of modern hydrofoiling vessels has already been initiated from the project.
In E2MUT we can use and further develop our core know-how in the area of calculation and optimisation of highly stressed fibre composite structures. At the same time, we are developing new competences in the areas of ship design, foil adaptivity, calculation of hydrodynamic loads, integration of propulsion systems, instrumentation and structural monitoring.
