Wasaline’s Aurora Botnia is equipped with our most technologically advanced solutions. On-board the ferry we continue testing Wärtsilä’s future innovations, while optimising its operations to the full potential.​

Welcome to innovate with us


In the heart of the
energy cluster

The ecosystem around STH is built on Wärtsilä’s technologies and partners’ capabilities, thus giving 360-degree showcase of our solutions and how an ecosystem operates. The location of STH in Vaasa furthermore strengthens the ecosystem. Together we are on a journey towards decarbonisation.
