Wärtsilä integrated propulsion solution to deliver future-proofing for new next-generation short-sea cargo vessel

Technology group Wärtsilä will supply a fully integrated propulsion solution for a new advanced open-deck carrier vessel. The vessel has been ordered by Finland-based operator Meriaura, as part of its fleet renewal programme and has been designed for low energy consumption, operational flexibility and minimised emissions. The order was booked by Wärtsilä in Q1 2026.

Vessel owners and operators are navigating a dynamic landscape shaped by evolving market conditions, regulatory requirements, and an increasing focus on emission reductions. As a result, there is a growing need for advanced solutions that support both operational flexibility and significant reductions in greenhouse gas emissions in line with international decarbonisation targets.

“This advanced vessel marks a significant milestone in our fleet renewal programme, further enhancing our capabilities in heavy project and special-cargo transport”, says Jessica Saari, Business Development Director – Meriaura. “With increased capacity, future-fuel-ready Wärtsilä engines and improved operational flexibility, we are well positioned to serve our customers more efficiently and sustainably across a broader range of routes and operating conditions.”

The 6,800 DWT ice-class, short-sea vessel will be equipped with a fully integrated propulsion solution from Wärtsilä. The modular design of two Wärtsilä 25 main engines, which combine fuel flexibility with advanced emission control, will help Meriaura significantly reduce greenhouse gas emissions. The scope also includes one Wärtsilä 20 engine and a Wärtsilä Selective Catalytic Reduction (SCR) system, further advancing emission control and environmental performance.

Alongside the engines, Wärtsilä will deliver a full electric propulsion system which will improve propulsion efficiency, contributing to lower fuel consumption and reliable, sustainable operations. Additionally, three Wärtsilä transverse thrusters will enhance the vessel’s dynamic positioning capability, supporting station keeping during offshore construction and heavy lifting operations.

“This advanced newbuild project demonstrates the shipping industry’s drive to decarbonisation through adopting flexible, efficient, and sustainable solutions with built-in readiness for sustainable fuels. By combining engines, electric propulsion, and advanced manoeuvring technologies, we will enable Meriaura to achieve both operational flexibility and emissions savings for this new vessel”, comments Mika Ojutkangas, General Manager, Sales. Finland and Baltics – Wärtsilä Marine.

Wärtsilä’s equipment delivery is scheduled for mid‑2027, ahead of the vessel’s planned entry into service in early 2028.
