Eco-conscious Brazilian port chooses Wartsila's bunker-saving hybrid tug

The HYTug features hybrid propulsion and energy storage using batteries.

Finnish firm Wartsila has signed a memorandum of understanding (MoU) with Petrocity, the parent company of the new port facility being built in the Brazilian city of Sao Mateus, to develop a harbour tug design.

Given that the prime consideration of the project is to maximize the ecological operational sustainability of the vessel since the environmental demands of the new port are among the most stringent in the world, the design will be based on the recently launched Wartsila HYTug, which features hybrid propulsion and energy storage using batteries.

According to Wartsila, the HYTug provides environmental sustainability, operational efficiency, and lower fuel consumption than is possible with conventional tug designs. The fully integrated hybrid power module combines engines, the energy storage system, and power electronics optimised to work together through a newly developed energy management system (EMS). Wartsila describes it as "a new frontier in marine hybrid propulsion".

When operating in 'green' mode, Wartsila says "it is unlikely" that there will be any visible smoke from the Wartsila HYTug since the load is being picked-up by the batteries. At the same time, the noise level of the tug will be "notably reduced", the technology provider claims.

"The Wartsila HYTug will change the landscape of the tugboat market as battery usage significantly increases environmental sustainability and operational efficiency, while at the same time greatly reducing operating costs. It represents further evidence of Wartsila's leadership position in sustainable and energy efficient technologies," remarked Marine Solutions Sales Manager, Mario Barbosa.

"Green port operations are completely aligned with Petrocity's corporate philosophy and values. We look forward to working with Wartsila in developing the kind of harbour tug that meets the criteria that have been established for this project," said Jose Roberto, CEO of Petrocity.
