Hull Shape Design Optimization
The case is about a hull optimization of a large passenger ferry.
The objective is to reduce the required power at 2 different cruise speeds and loading conditions but also to explore the parameters influence to better understand their impact on the objectives.
There is a power reduction of 14,08% and a decrease of 13,53% of the fuel consumption which leads to a saving of 337,000$ per year for two engines (1 boat).
A fully automated design optimization of a ferry is performed to find the global optimum of the weighted power, hence allowing the trade-off studies much easier.
The propeller influence is taken into account by means of an enriched actuator disk model to directly perform self-propulsion simulations.
The data mining leads to decrease the CPU time for the database by validating the accuracy of the surrogate.
