Wärtsilä on 10-year maintenance contract for Wasaline’s flagship – ShipInsight


Wärtsilä and Wasaline, the Finnish-Swedish shipping company, have a ten-year Optimized Maintenance Agreement for the company’s new ferry, the Aurora Botnia. The agreement was signed in June but came into force in September.

The one built at the RMC shipyard in Finland Aurora Botnia is the most environmentally friendly RoPax ferry in the world. The ship propulsion is based on a hybrid solution with the highly efficient Wärtsilä 31DF dual-fuel motor and batteries. The Wärtsilä 31DF runs primarily on LNG fuel, but can also use BioLNG, a fully renewable fuel that can reduce CO2 emissions by up to 90 percent compared to traditional marine fuels. It emits no fine dust particles and almost zero values ​​of NOx and sulfur oxides SOx.

The comprehensive Wärtsilä Optimized maintenance contract includes the latest digital solutions based on artificial intelligence to provide effective support for predictive maintenance and the ability to detect potential errors before they actually occur. The service also makes it possible to coordinate operations so that the carbon footprint remains low and unplanned downtime is minimized. The ship will act as a floating test laboratory connected to Wärtsilä’s Smart Technology Hub in Vaasa, Finland, enabling real-time operational monitoring. This maximizes efficiency and provides valuable data for future developments of solutions with the highest sustainability.

“We have been working closely with Wärtsilä for a long time and this partnership has paid off enormously in terms of efficiency and environmental sustainability. We therefore decided without hesitation to sign a Wärtsilä maintenance contract for this new ship, which will be the first car and passenger ferry in the world with a clean design class. It already fulfills the proposed EU Fit for 55 program, which aims to reduce CO2 emissions by 55% by 2030 ”, said Peter Ståhlberg, Managing Director of Wasaline.

“This latest agreement underscores the strong partnership between Wärtsilä and Wasaline and we are very proud to be part of this project. It is a real showcase for Wärtsilä and the energy cluster how we can help reduce the shipping sector’s carbon footprint. As part of our lifecycle approach, long-term maintenance contracts are designed to support the operational and business performance of our customers, ”said Henrik Wilhelms, Director, Agreement Sales, Wärtsilä Marine Power.

In addition to the hybrid drive, the Aurora Botnia also has the Wärtsilä Data Bridge platform. This enables advanced data analyzes that provide insight into the ship’s performance at any time and thus open up further potential for improving operational and technical efficiency.

The ship is operated with four Wärtsilä 31DF engines, the LNG Pac gas storage solution from Wärtsilä and Wärtsilä engines, catalysts, controls, integrated electrical and automation systems and an energy and power management system to control the hybrid propulsion solution. The ferry also has Wärtsilä’s integrated Nacos Platinum ship control system.

The 150 meter long ferry will have a capacity of 800 passengers and 1500 gauge for vehicles. It will run between Vaasa in Finland and Umeå in Sweden. Both ports will offer LNG bunkers and battery charging facilities. The environmentally friendly ship will help preserve the Kvarken World Heritage through which it is operated.
