Azistern tugs around the world prove their value for the various tasks they have been designed for. Did you know we also have a hybrid e-tug design available?

      YOUR TUG FLEET FUTURE-PROOF

      To offer you a future proof solution, OSD-IMT has designed the Azistern-e tug series. A series of powerful, low emission compact e-tugs to further augment its Azistern series of tugs. Among other roles, these vessels are perfectly equipped to deliver excellent harbour assistance.

    • Maximum flexibility, optimal sustainability

      We help you lower the impact of your fleet on the environment using batteries for peak shaving and as propulsion energy storage. The hybrid power of an Azistern-e tug is delivered by two low maintenance gensets and two battery packs. These environmentally friendly tugs can be delivered with IMO Tier 3 equipment, suitable for ECA areas.

    • Advantages

      The useful extras of an Azistern-e tug:

      • Low fuel consumption
      • Emission control
      • Better engine loading
      • Les running hours
      • Less noise and vibration
      • Smaller gensets
      • Flexible weight distribution
    • High performance tugs

      Azistern-e tugs are highly manoeuvrable. The power train has a remarkably short reaction time. By using the batteries as a booster, maximum bollard pull can be achieved within six seconds. The relatively small size of the engines frees up more space below deck.
