The Wärtsilä HY for Dredger features a combination of different power sources, including the engines and energy storage systems, the power distribution equipment, and the Energy Management System (EMS). The EMS ensures instant load taking and dynamic power demand. It also has the capability for intelligent tuning to optimise performance throughout the vessel’s lifecycle.

Full integration of the various systems enables smooth and continuous operations in all operating conditions, thereby allowing the engines to always run at optimal load. This increases energy efficiency, which leads in turn to substantial savings in fuel consumption. At the same time, reducing stress on mechanical components results in lower maintenance costs and extended turbocharger life. Sustainability is enhanced with reduced emission levels in all modes, with zero emissions when running in full battery mode.

This latest hybrid product development represents a further step in the realisation of Wärtsilä ’s smart marine ecosystem vision, whereby the development of smart technologies will create greater efficiency, higher safety, and better environmental performance. The company is committed to improving the sustainability of maritime operations.
