Finland-based ship designer Deltamarin has sealed a deal with China Merchants Jinling Shipyard (Weihai) for the design and engineering of the 14th and 15th vessels in Stena RoRo’s E-Flexer series.

The vessels will be built by Stena RoRo at the CMI Jinling Shipyard (Weihai) in China and are scheduled for delivery in April and August 2027.

As it is reported, the newbuilds will be chartered by Attica Group for operations on Adriatic routes, with an option for two additional E-Flexers.

These designs are expected to reduce the fuel efficiency and Attica Group’s greenhouse gas emissions by up to 60% per transport work, compared to existing vessels.

The deal covers the complete basic and detail design of two new multi-fuel E-Flexer RoPax vessels, both of which will be methanol-ready.

The new design vessels will be able to operate on conventional marine fuels (HFO or MGO), biodiesel, and are methanol ready.

Deltamarin said that the total number of confirmed E-Flexer orders rises now to 15, of which ten have already been delivered.

“The continued interest in the E-Flexer vessels, as evidence by the high number of orders, highlights their value and positions them as the leading solution in their class. We value our longstanding partnership with Stena and CMI and look forward to advancing these projects together,” said Janne Uotila, managing director of Deltamarin.

“With Attica and Deltamarin, we have developed the most bespoke E-Flexer concept so far, and this design is a new landmark for highly efficient, cost-effective, and future-proof RoPax vessels. With the capability of using both conventional fuel, biodiesel, bio- and e-Methanol, as well as batteries for propulsion, the shipowner has a vessel that can be operated with zero CO2 emissions in the future,” noted Per Westling, CEO of Stena RoRo AB.
