KOTUG offers electric-powered pusher tugs, and smart AI-driven dispatch and route planning applications for the inland water transportation industry. With these logistics solutions, KOTUG aims to support the worldwide energy transition and the modal shift from road transport to waterways while meeting the growing demand for electric-powered vessels.  


The KOTUG inland shipping activities are a combination of a range of modular and scalable electric pusher tugs, the E-Pusher™ Series, powered by swappable energy containers, and its smart AI-driven dispatch and route planning application OptiPort. The E-Pusher™ Series currently has three models ranging from 5,5 to 22 meters in length and a maximum depth of 0,6 to 1,35 meters resulting in a draft that is 30% less than conventional pusher tug designs.

Due to the modular approach and lean assembly method, KOTUG reduced the construction time of the E-Pusher™ by at least 25% compared to traditional vessels. The swappable energy containers range from Stage V diesel, (Bio)gas and Hydrogen to battery solutions.

Smart operations

For smart operations KOTUG uses OptiPort, its advanced dispatching, route-planning and reporting tool. KOTUG OptiPort is an automated dispatching system based on historical and real-time information bridging port and terminal information with ship operations. The tool supports fleet owners in optimizing expected departure- and arrival times, routing and speed control, leading to reduced energy usage and just-in-time departure and arrival.  The system is active since 2017 and is currently in use by vessel operators in countries as Australia, the United States, Japan, Belgium, Netherlands and Canada.




Together with partner Circle Line Logistics the E-Pusher™ S-type is marketed under the name CityBarge, designed for silent and emission-free transport in cities. The vessel is already in use in the Municipality of Leiden for the transport of waste via the historic canals in the city centre. Other applications of the CityBarge are transportation of construction materials and retail products. Click here for more information on the CityBarge.
