The first two vessels in a series of 12 new hybrid high-speed ferries designed by Incat Crowther and built by Astilleros Armon in Spain for Italian ferry operator Liberty Lines have exceeded performance expectations during sea trials and will soon begin servicing routes between Sicily and nearby islands.
Named Vittorio Morace and HSC Cristina M, the new 38m monohull vessels have proven their ability to operate at speeds of up to 30 knots when carrying a full load, with a sprint speed of 33 knots. The Sicily-based operator and builder Armon worked closely with Incat Crowther on the customised, high-speed, low-emission hybrid propulsion fleet.
Each vessel is equipped with an integrated hybrid propulsion system that includes MTU 16V4000M65L engines providing both conventional and electric propulsion. In addition, each vessel features two e-motors, two variable-speed gensets, a battery system, electrical power management system and an MTU hybrid automation system.
This integrated system allows the fleet to enter and exit port in a zero-emissions mode at speeds of up to eight knots, with the ability to recharge each vessel via shoreside infrastructure during longer stops. The vessels can operate in a hybrid propulsion mode, reaching high speeds while recharging their batteries via the two main engines. In a further future-focused design element, the vessels are also ready for conversion to hydrogen consumption in the future. The new vessels are designed to transport up to 251 passengers.
Carlo Cotella, CEO Liberty Lines said: “With this project, we are making a sustainable investment in the renewal of our fleet, with the purpose to continue to offer high-quality services to our stakeholders and minimise environmental impact in order to achieve an emission-free future.”
Incat Crowther CEO Brett Crowther added, “The launches of Vittorio Morace and HSC Cristina M provide a glimpse into the future of low emission public transport. These vessels are a smart, long-term investment by Liberty Lines as not only do they help the company sustainably expand its fleet today, but they are also future-proofed for an operationally efficient, zero-emissions future as alternative fuels become more economically viable for operators.”
The other 10 vessels in the fleet are expected to follow Vittorio Morace and HSC Cristina M into service between 2024 and 2029.
