French shipbuilder OCEA has handed over the first in a series of four catamaran waterbuses to the Bordeaux Métropole region in southwestern France. The vessel, called La Linotte, will be part of the Le Bato shuttle boat network on the Garonne River, offering increased passenger and bicycle capacity compared to earlier waterbuses. La Linotte features a hybrid diesel-electric propulsion system with plans for future hydrogen fuel cell installation to achieve zero-emission operations. The waterbus is made from recycled aluminium to reduce environmental impact and is designed for sustainable daily use similar to traditional land buses. It is equipped with rechargeable batteries, generators, and waterjets, with the capability to transition to hydrogen propulsion. Challenges in the design process included fitting the hydrogen-ready system in a limited space and ensuring compliance with stringent European inland regulations. The vessel's operation includes charging at one stop during nighttime, requiring high-capacity batteries for extended operation. Remote monitoring of the propulsion system ensures high availability in case of malfunctions. The waterbus design focuses on maintaining zero emissions and fulfilling daily operational requirements while meeting strict regulatory standards. OCEA aims to deliver the remaining waterbuses in the series next year, offering an innovative and sustainable solution for public transport in Bordeaux.
