This thesis is part of the joint work between the Institute of Internal Combustion Engines (IFKM, KIT), WinGD in Winterthur, and Gamma Technologies in Stuttgart.

WinGD is a leading developer of low-speed Gas and Diesel 2-stroke engines used for propulsion power in merchant shipping. These engines are utilized for the propulsion of all types of deep-sea ships world-wide, such as oil and gas tankers, bulk carriers, car carriers, general cargo ships and container ships. The company continues the long tradition of the Sulzer Diesel Engine business founded in 1898. WinGD's headquarters is located in Winterthur, Switzerland.

Gamma Technologies is the developer of GT-SUITE, the leading multi-physics CAE system simulation software. GT-SUITE supplies a comprehensive set of component libraries which simulate the physics of fluid flow, thermal, mechanical, electrical, magnetic, chemistry, and controls. From those libraries, one can build accurate models of almost any engineering system, including vehicles, combustion engines, energy storage and power supply systems, hydraulics, thermal management, aftertreatment and much more.

Thesis Proposal

Driven by the IMO GHG strategy the shipping industry is obliged has to reduce its GHG emissions in 2050 by 50% (compared to 2008). This ambitious target may be achieved by switching to alternative fuels, in particular, if supported by additional measures like electrification, usage of renewable energy sources, or optimization of ship operation itself. In this regard, WinGD not only provides highly efficient combustion engine technology but also its integration into an electrified powertrain.
In order to seize the full potential of such an electrified propulsion system it is necessary to consider a ship’s voyage or operational profile. Being able to adjust such profile may result in additional fuel savings. This research approach goes beyond the state of the art techniques since high-fidelity hydrodynamic or thermodynamic model are utilized and coupled. Dynamic interactions may be modeled (e.g. wave loading) and their implication on propulsion system behavior (e.g. fluctuation of fuel consumption) can be predicted. In this context, the suggested thesis aims to verify the model approach while quantifying the fuel saving potential for selected voyage optimization techniques (e.g. energy management control strategies, usage of wind power, etc.).
