The technology group Wärtsilä, announced that it has adapted its hybrid tug design to meet the needs of the Chinese market. The new version of the Wärtsilä HYTug has received an Approval-in-Principle recognition by the China Classification Society (CCS).

The Wärtsilä HYTug focuses on environmental sustainability, operational efficiency, and lower fuel consumption. The new tug incorporates engines, an energy storage system using batteries, and power electronics optimised to work together through an energy management system (EMS).

When operating in ‘green’ mode, the visible smoke from the Wärtsilä HYTug will be reduced, because the load will be picked-up by the batteries. The noise level of the tug will be reduced as well.

The new design will be available in three different hull sizes, a 28m harbour tug with a 50t bollard pull, a 29.5m harbour tug with a 75t bollard pull, and a 35m escort tug with a 75t bollard pull.

Furthermore, the propulsion system will give the possibility to select either diesel mechanical hybrid or diesel electric hybrid propulsion.

The Wärtsilä HYTug with CCS Approval-in-Principle is expected to be announced at the Marintec conference and exhibition, in Shanghai from 5 to 8 December.
