Purpose and goal
The aim of the study was to show that it can produce an environmentally-friendly passenger transport without emissions operating in protected waters, mainly with regard to water in the metropolitan regions. The aim was also to minimal disturbance to the environment in the form of wash waves. Another important factor was that the transport system would be effective despite the battery operation, ie the charging times would not affect the business negatively.
Results and expected effects
Model tests have shown that the developed hull structure shows significantly lower power consumption than conventional hull which in itself is a prerequisite for being able to utilize battery power. The design also shows acceptable levels of backwash, which is important for inland waters. It has also been shown that the chosen propulsion system is very effective and that with modern battery technology that can manage the demands of being operational.
Approach and implementation
The project´s approach has proven true, however, the project has suffered several delays mainly because the project has great innovative features such as the manufacture of the prototype vessel in carbon fiber, battery operation, requiring high speed, etc. Preliminary hull design and verification model tests and the selection of the correct propulsor has taken time but given the project a real focus.
