Former Nevesbu graduation student Marjolein receives KNVTS Maritime Students Award 2018

Former Nevesbu graduation student Marjolein receives KNVTS Maritime Students Award 2018 November 2018 - The Maritime Students Awards is an award for ‘the best of the best’ graduation students. In 2017, Marjolein graduated from the Technical University in Delft with an impressive 9. The subject of her graduation thesis was ‘submarine propulsion plant design using mean value first principle models’.

A naval submarine sails in different operational modes: surfaced, at periscope depth or submerged. It needs an appropriate power plant to do so. The impact of the selected power plant on the overall submarine design is significant. Selecting the correct components of the power plant in an early stage is, therefore, key to a successful design. Current early-stage design methods are based on known design solutions such as diesel-electric or fuel-cell driven power plants and have difficulty with novel solutions such as a combination of diesel-electric and fuel cells.

Marjolein has conducted research into an earlier developed mean value first principle power plant model, extended with a PEM Fuel Cell model as an Air Independent Power (AIP) system and a Permanent Magnet Synchronous Machine model as a propulsion motor. The model enables optimisation of a submarine power plant to balance the required space, mass and operational performances based on a pre-set operational profile. The result of this research provides insight into optimised design concepts concerning volume, mass and efficiency (ultimately operational cost), given that operational needs extend beyond current submarine capabilities.

Marjolein, we are proud of you! Winning an award for ‘the best of the best’ graduation students is not easily just done.
