lumarine Shipyard has delivered a new hydrographic survey boat that is powered by an innovative dual electric/ diesel propulsion system to the Port of La Rochelle. The 8m aluminium Cassiopée will provide bathymetric surveys of the ocean floor to collect data that will be used to map the underwater landscape, ensuring safe navigation in and around the port. The high-speed vessel has been designed to the specifications of the team at La Rochelle. The shape of its hull is suited to the sea conditions in the area and offers the required stability during survey work. Its deck plan and equipment allow the crew to work in comfort and safety, and workspace has been optimised in the wheelhouse. The choice of aluminium for this construction
was immediately obvious, according to Philippe Texier, Head of the Maritime Access and Land Infrastructures at the Port of La Rochelle. “In addition to being light and robust, it is a material that allows tailormade solutions and changes at a later stage, unlike a polyester hull on which future alterations are more complex.”
Innovative dual drive
One of the vessel’s special features is the hybrid propulsion system, supplied by Torqeedo. The company worked closely with the naval architect and shipyard to specify, install, and integrate an electric propulsion package consisting of two Cruise 10.0 R electric outboards, each powered by four Power 48-5000 lithium batteries.
