Bureau Veritas (BV) has been contracted for the classification of 10 electric ferries, currently under construction by Gondán Shipyard in Spain for the Portuguese river passenger operator, Transtejo.

The sister vessels will come into service between 2022 and 2024. and will be 100% electrical. With a capacity of 540 passengers each, the ferries will provide a public transport service on the Tagus River, between Lisbon city centre and three different cities on the southern shore of the river.

The electric power and propulsion system for the 40m long GRP ferries, with catamaran-type hulls optimised to make the most of the 2MWh batteries, will be based on ABB’s Onboard DC Grid power distribution system to ensure an optimal delivery of the battery output to the ferry’s subsystems. The charging system will be centrally located on the vessels, allowing charging on both port and starboard from towers located on the terminal’s floating pontoons. The vessels’ energy storage systems (ESS) are designed for a complete round trip on the longest planned route (using between 20-90% of maximum capacity). In daytime, the vessels will use fast charging (3MW-4MW), while slow charging (0.15MW-0.2MW) will be used during the night.

In addition, the ferries will receive BV Comf-Noise 3 and Comf-Vib 3 notations, reflecting minimised levels of noise and vibration for passenger comfort. The vessels will receive BV notations: Passenger Vessel, Battery System, C (composites) and AUT-UMS (automated vessel).

Mathieu Philippe, Commercial Director, BV Marine & Offshore, said: “These ferries are the perfect illustration of demand for new urban transportation. Zero-emission propulsion is available today for sustainable and fast passenger ferry transport. We are proud to support this 'business to business to society' project, which demonstrates our technical expertise as well as our commitment to shaping a better world.”

BV says it provides a range of rules relating to inland navigation covering vessels, floating structures, and harbour equipment. A growing number of countries require classification for ships operating on inland waterways and BV has opened offices in main inland waterway hubs. BV provides support to flag state authorities to help develop national requirements in cases where no regulations have yet been implemented.
