Through a detailed review of limitations and route requirements for the three use-cases (Stavanger, London and Belgium) in the TrAM project, the project has established requirements that has functioned as a starting point for the design of these vessels.
Parametric optimisation analyses have been performed for the Stavanger Demonstrator use-case, and has been progressed also for the London replicator in reporting period 2. The target for the project is to significantly improve the energy consumption per passenger compared to traditional fast-ferries, and the hull optimazation analyses are therefore a very important part of achieving this target. Tank testing of 2 different hull designs have been completed in two testing campaigns at HSVA's towing tank, confirming the efficiency in both hull design and propulsion system.
The main driver for achieving the goals of reducing engineering hours and production cost for vessels built with the TrAM methodology, is to modularise both the design and the production. The TrAM project has worked towards modularising the vessel in a way that will both enable re-use of design and components, standardising interfaces between modules, as well as proving the modularisation to be practical and economical for the industrial partners. The TrAM vessel has been divided into several macro-modules that again has been split into several of micro-modules. Parts of these proposed modularisation methods are beeing incorporated into the ongoing production of the Stavanger Demonstrator.
The Stavanger Demonstrator vessel is currently under production, with a planned delivery spring 2022.
The land-side charging infrastructure design is concluded and construction work started autumn 2021. The planned completion is spring 2022, ahead of the delivery of the Stavanger Demonstrator.
