Wärtsilä to develop St Matthew port tug using hybrid battery propulsion
Wärtsilä said it will develop a St Matthew port tug design aimed at meeting the port’s very strict environmental requirements. The tug will be based on its HYTug hybrid tug concept, using batteries for energy storage and a fully integrated hybrid power module with energy management. Wärtsilä claims lower fuel use and exhaust emissions, less visible smoke in green mode, and reduced noise levels, along with lower operating costs.
