Model Predictive DC Voltage Control for all-electric ships
Control Engineering Practice, 2019Abstract With the advent of on-board Direct Current (DC) power and propulsion systems, the transmission and delivery of energy on board of ships can be carried out more efficiently as it is being done using conventional direct-diesel or Alternative Current (AC) power and propulsion systems.

Assessing the dynamic secure region for an all-electric ship model
2012 North American Power Symposium (NAPS), 2012Dynamic security is an important factor in survivability of all-electric ships. On the other hand, region-based security assessment methods are efficient for online applications. In this paper, a deterministic method is presented to assess Dynamic Secure Region (DSR) in all-electric ships.

High-power electric drives for all-electric ships
2010The use of electric drives for large ship propulsion is a spreading trend in today’s marine industry thanks to the benefits it brings not only in dynamic performance and noise reduction but also from an environmental and energy-saving viewpoint. In fact, using electric motors enables to operate on-board prime movers (diesel engines above all) close to ...

Integrating the FEL on an all-electric ship
2012This thesis examines the feasibility of placing the free electron laser (FEL) on the all-electric ship. The power required by the FEL and the tolerance of the FEL to vibrations is determined using computer simulations. Methods of reducing the vibrations using vibration isolation and active alignment are described.
