Summer Power Hybrid- shared activities for trainees!

We plan to offer events and gatherings in Vaasa, Turku and Helsinki with online options to make sure we can all enjoy the summer together - and we invite you to ideate on what you would like to participate in!   

It is vital that our newest Wärtsilians, some joining us for the first time in the summer, feel welcome, have a way to connect with people and to see how much we appreciate their work. That is why the Summer Power Hybrid- program was created in 2020.
