• Title: "Study of Artificial Neural Networks in maritime applications"

• Abstract:

Alternative models based on Artificial Neural Networks (ANNs) have been developed for several maritime applications (maneuvering, routing, structures), allowing the prediction of certain variables without using explicit mathematical models. The developed models have been innovative in the respective applications, providing very good results and showing to be an adequate and expedite alternative to the traditional mathematical models. Moreover, the principal asset of the neural networks-based models is that the parameters used for the training are easily obtained onboard existing ships or in tests with models. This Seminar will present several results obtained in different applications, such as the assessment of the ship maneuverability performance, the estimation of wave-induced ship hull bending moment and shear force, and the estimations of ship speed and the Fuel Oil Consumption (FOC) from the output torque of the main engine, the RPM of the propulsion shaft, the significant wave height, the peak period of the waves, and the relative angle of wave encounter measurements.

• Short Biographic Note:

Lúcia Moreira is currently an Assistant Professor in the Scientific Area of Naval Architecture and Marine Engineering of the Department of Mechanical Engineering (DEM) at IST. She graduated in Naval Architecture and Ocean Engineering in 1998 and concluded a Masters in Marine Technology from the University of Newcastle upon Tyne, in the United Kingdom, in 2002. In 2003, she concluded a postgraduation in Systems, Decision and Control at the Department of Electrical and Computer Engineering at IST, and in 2004, she continued the studies in control and guidance of marine systems at the Norwegian University of Science and Technology (NTNU), in Trondheim, Norway. In 2008, she concluded the PhD in Naval Architecture and Marine Engineering, financed by the Fundação para a Ciência e Tecnologia. From 2009 to 2014, she worked as a postdoctoral researcher at the Centre for Marine Technology and Ocean Engineering (CENTEC). From 2015 to 2018, she worked as Professor and coordinator of the Mechanical Engineering degree at the Instituto Politécnico de Tecnologias e Ciências (ISPTEC) in Luanda, Angola, being responsible for the leadership, development and strategic and operational management of the degree. Since 2019 up to now, she develops research at CENTEC, mainly regarding the development and implementation of procedures based on Artificial Neural Networks (ANNs) for maritime applications. Some examples of these applications are the estimations of ship speed and fuel oil consumption, estimations of wave-induced bending moment and shear force from ship motions measurements, and the use of Recursive Neural Networks (RNNs) to predict manoeuvres based on sea trial data.

This is another Seminar of the “Seminars@DEM” cycle.
Next Seminar, July 3, 2025, Thursday, 3:00 pm.
