Dr Vilmar Æsøy

Vilmar Æsøy is part of the research team at Aalesund University College (AaUC) working on Marine Operations Simulation and Visualization. He graduated from NTNU in 1989, and continued his research on natural gas fuelled marine engines at NTNU/MARINTEK to 1997. In 1996 he received his PhD degree for his research on natural gas ignition and combustion through experimental investigations and numerical simulations. During the research period 1989-1997 he was engaged in several large R&D projects developing gas fuelled engines and fuel injection systems for the diesel engine manufacturers, Wärtsilä and Bergen Diesel (Rolls-Royce).

From 1998 to 2002 he went back to the marine industry where he worked as R&D manager for Rolls-Royce Marine Deck Machinery in Brattvåg. Since 2002 he has been employed in teaching at AaUC, developing and teaching courses in marine products and systems design on bachelor and master level. From January 2010 he received the “green ship machinery” professorship.

Through employment in the maritime industry, he has acquired a wide range of experience and knowledge, covering design of machinery systems, propulsion systems, internal combustion engines, hydraulic power and control systems. His special research interest is within the field of energy and environmental technology, with focus on combustion engines and the need for more environmentally friendly and energy efficient systems.
