1. Electrically powered manoeuvring of water jets
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknikSammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

2. Design and system integration of a rim jet solution utilizing DFMA
Master-uppsats, KTH/Integrerad produktutvecklingSammanfattning : Moving a new innovative idea from the drawing board to production is no easy feat. The Swedish sea rescue society (SSRS) has for the past years fostered a new design solution for their jet skis, a alternative water jet that removes the centre hub and utilises rim drive technology.

3. Användarcentrerad utvärdering samt utveckling av ett larmsystem för vattenjet-propulsor
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktionSammanfattning : The purpose of this master thesis is to investigate how alarm systems and their visualizations, as well as signals affect work situations and decision making processes aboard vessels with water jet propulsion. Furthermore, this study aims to identify important aspects of the perception of alarm systems and which aspects that are more or less affected by stress, lack of information as well as audible and visual signals.

4. Analysis of the intake grill for marine jet propulsion
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Marine waterjet propulsion is a technology that has been developed and refined since the early 1950’ and is proven highly useful for high speed applications with vessels in varying sizes. The intake grill is a component that is mounted in line with the hull to prevent debris from traveling through the waterjet. LÄS MER
5. Rim-Jet - A Mechanical Design for a Shaft-less Propulsor
Master-uppsats, KTH/Maskinkonstruktion (Avd.)Sammanfattning : During sea rescue operations it is common for the rescue vessels to operate in water with high number of debris that can get stuck in the propulsor. In particular plastic ropes that can get tangled around the shaft and melt causing a complete stop or damage the motor. LÄS MER
