The Wärtsilä supply base is extensive with around 28,000 active supplier accounts, with most key suppliers being located in Europe.

The expectation we have on ourselves and our supplier network is that we together continuously work on improving our performance and processes towards operational excellence. This requires that we constantly measure the performance and effectiveness of our processes, and seek opportunities for improvement, for example through benchmarking. We work in close co-operation with our suppliers to build relations based on strong trust, sharing of information, and to help to ensure competitive lead times for products & services. In addition, as part of our research and development activities, we collaborate with key suppliers, universities and research institutes to form strategic partnerships and develop new and existing solutions.
