Production has started in China on the first in six ships ordered by Stena Line - two of which will operate on the Belfast to Liverpool route.
It is the first of six vessels ordered by the firm - E-Flexer RoPax ferries will be capable of carrying 1,000 passengers and over 120 cars.
The ferries will be among the most energy efficient in the world, with significantly lower C02 emissions per freight, compared to RoPax tonnage.
They will increase the capacity for freight and customers wishing to travel between Belfast to Liverpool.
Three of the ships (including the E-Flexer RoPax) will be located on the Irish Sea routes, while the other three will be chartered out to external parties by Stena Line's sister company Stena Roro.
Paul Grant, Stena Line’s Trade Director (Irish Sea North) says they are "delighted" that two of the new fleets will be entering service on their expanding Belfast to Liverpool route.
Paul commented: “Everyone on the route is looking forward to welcoming the new generation of ferries to Belfast.
"It’s a real vote of confidence in the future development of our operations in the region.”
"The ships will be ‘drive-through’ making the loading and disembarkation processes faster and smoother for vehicles.”
The two vessels are planned to set sail in spring 2020 when they start their voyage from Belfast to Liverpool.
