The deck mounted azimuth thruster is a containerized thruster propulsion system that can be placed right on the deck of the vessel or barge. The compact structure, high mobility and easy installation makes it very suitable for barges, ferries and jack-up vessels. The whole unit can be installed directly on the deck, and it can be equipped with a lifting and swing up function. The vertical height can be adjusted to give the ship better possibilities for the change in draft.
