Activities related to the engine innovation involves applying a novel combustion concept for Dual Fuel medium speed gas engine mode on prototype engines and for its further validation for future market introduction.
The basic principle is to achieve very fast and ultra-lean cold combustion by controlling the air-gas mixture self-ignition point, adjusting the compression end temperature and the air-gas mixture reactivity in every specific engine operating point. We have successfully developed and validated this innovation and released it for sales under the name of W31DF Enviropac engine.
Facilitating engine innovation in SEATECH, Liewenthal Electronics has re-worked the FPGA firmware development workflow for the control modules in charge of cylinder operation and monitoring. The improved workflow enables developers to spend remarkably less time on manually translating the system requirements and MATLAB Simulink models into FPGA source code. Instead, much of the process has now been automated as a result of architectural changes in firmware, combined with the integration of a commercially available tool capable of automatic model-to-code translation.
Apart from planning, implementing and verifying the needed firmware changes, Liewenthal Electronics has also written a user guide for Wärtsilä FPGA engineers working on cylinder control functionality to effectively apply the new workflow in daily development.
Overall, contribution from Liewenthal Electronics has helped significantly reduce FPGA development time, thus increasing schedule and cost efficiency of engine innovation.
The bio-mimetic dynamic wing innovation has undergone testing with small ship models in both wave tank laboratories, to better evaluate the performance depending on wave height, type, and direction. A 10 meter large-scale model was constructed and tested in real sea conditions in the Aegean Sea.
Utkilen AS has supplied the project with empirical data from a selected vessel within their fleet, detailing its performance in real-world operational conditions. Additionally, Utkilen AS contributed with domain expertise in the operation and maintenance of chemical tankers in Northern Europe.
A full Life Cycle Cost Analysis (LCCA) has been made comparing current state of the art ship technology compared with a vessel equipped with the SeaTech innovations. The calculations include both newbuild, retrofit and whole lifecycle costs. Operational data of each innovation has been collected into an Advanced Data Analytics Framework (ADAF), which is made publicly available for future research use.
All outcomes and progress, including all conference papers and journal articles, have been collected on our website at seatech2020.eu.
