Italian ferry operator Liberty Lines has expanded its order of 38m hybrid monohull passenger ferries from Incat Crowther with three additional vessels added to the original order of nine.
Each of the 12 new vessels will offer a flexible hybrid drivetrain and will have the ability to enter and leave ports at speeds up to 8 knots in zero-emission mode. The expansion of the project comes following Incat Crowther’s digital design process delivered a forward-thinking solution for the Trapani-based operator. With construction underway at Astilleros Armon’s shipyard in Spain, delivery of the vessels is expected to take place between 2023 and 2026. Each vessel will be capable of a speed of 30 knots and can accommodate 251 passengers
Liberty Lines CEO Gennaro Carlo Cotella 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.”
The ships will be equipped with Rolls-Royce integrated MTU hybrid propulsion systems, each comprising two 16V4000M65L engines, two gearboxes, two e-motors and electric systems, two variable-speed gensets, a battery system, switchboard, electrical power management system and an MTU hybrid automation system. The advanced hybrid system will call upon different operating modes as required. In all-electric mode, the vessels will have no emissions to a speed of 8 knots. In hybrid mode, they can reach a high cruise speed when travelling across the sea, whilst simultaneously charging the batteries by the two main engines and deactivating the gensets for hotel load. During longer stops, the batteries are charged by means of the shore power supply.
Incat Crowther CEO Brett Crowther said: “This project requires our team of marine designers to integrate new and cutting-edge technology into bespoke designs for our client, while ensuring we meet all regulatory requirements. Our work with Liberty Lines is yet another example of the ability of Incat Crowther to design and deliver tailored and innovative low-emission high-speed ferries for operators all around the world. We’re seeing growing demand for low and zero-emission passenger ferries, and our proven digital design process means Incat Crowther is perfectly placed to help operators both reduce emissions and increase operational efficiency as the world transitions to a net zero future.”
