Technology group - Wärtsilä has been selected as the electrical integrator for a major battery extension project for the Wasaline ROPAX ferry - ‘Aurora Botnia’. The project will increase the ship’s battery capacity by 10.4 MWh, from 2.2 MWh to 12.6 MWh, making it the world’s largest marine battery hybrid system in operation. The order with Wärtsilä was booked in Q3 2025. Hybrid propulsion systems Hybrid propulsion systems have emerged as a compellin...

Naval architecture and engineering consultancy Foreship is supporting Wasaline in delivering a breakthrough battery upgrade on MV Aurora Botnia that will see the ferry’s energy storage capacity increase nearly sixfold. The world-first retrofit will combine two battery chemistries in a hybrid solution that is expected to cut annual CO₂ emissions by up to 23%. Relationship between Wasaline and Foreship Foreship provided comprehensive technical and strategic support for the retrofit Build...

Technology group - Wärtsilä has introduced a new ultra-low emissions version of its already efficient Wärtsilä 31DF engine. Whilst operating on LNG, this new version can further reduce methane emissions on a 50 percent load point by up to 56 percent and nitrogen oxide (NOx) by up to 86 percent. On a weighted average, this new technology can reduce methane emissions by 41 percent more than the standard Wärtsilä 31DF engine, which has already the lowest emission leve...
