W\u00e4rtsil\u00e4 completed the system integration within a tight schedule, ensuring minimal operational disruption. The Danfoss drives were configured for the added batteries and updated to their latest versions, equipping Aurora Botnia with state-of-the-art drive technology. Foreship did the evaluation and basic Design.<\/p>\n<p>\u2013 This has been an interesting but also highly demanding project, particularly given the limited timeframe. The entire propulsion system was upgraded during docking, and battery optimization continued while the vessel was back in operation. Our partners did a tremendous job, says <strong>Jonas Teir<\/strong>, Technical Director of Wasaline.<\/p>\n<p>\u2013 We would like to extend our sincere thanks to all above partners involved, to Rescue Team Finland for excellent on site assistance with everything from fire watches to installation work, to Tallinn Shipyard for steel and pipe works and a special thanks to the entire crew especially the technical department onboard for their professionalism and extreme adoptability that is needed to execute this kind of a project during normal operations, Teir concludes.<\/p>\n<p>With this milestone, Wasaline further strengthens its position at the forefront of sustainable maritime transport and technological innovation.<\/p>\n<p><strong>For more information, contact:<\/strong><\/p>\n<p>Jonas Teir, Technical Director, Wasaline<br \/>\njonas.teir@wasaline.com, +358 50 374 5292<\/p>\n<p><strong>Press contact:<\/strong><\/p>\n<p>Catarina Fant, Director, Brand &amp; Communications, Wasaline<br \/>\ncatarina.fant@wasaline.com, +358 46 921 5811<\/p>\n<\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Wasaline has successfully completed sea trials following a major battery upgrade on board Aurora Botnia, which now features the largest battery capacity ever installed on a RoPax vessel worldwide.
