Offshore Ship Designers: A powerful, low-emission compact e-tug

The Azistern-e is a powerful, low-emission compact e-tug. Among other roles, the vessel is perfectly equipped to deliver excellent harbour assistance.

The hybrid power of the 22 m LOA / 50 BP Azistern-e is generated by two 970 kW variable speed gensets and is supported by two 400kWh lithium battery packs. The low-emission tug can be delivered compliant with IMO Tier 3 requirements with after-treatment system suitable for ECA areas and is equipped with an innovative energy management system as well. The uniform and perfectly optimized loading of the propulsion system ensures low maintenance and fuel costs. Transient sailing and maneuvering can be performed using the batteries with zero emissions.
