Padmos signs up to build Kotug E-Pusher tugs

The E-Pusher is a modular and scalable electric pusher tug featuring swappable energy containers with Stage V diesel, biogas, hydrogen and battery power provisions.

The E-Pusher moved from being purely a concept in 2023, when Padmos built an M-Model, fully-electric example named E-Pusher 1 to move barges loaded with cocoa beans between Amsterdam and Zaandam for global food corporation Cargill.

Kotug says the operation reduces CO₂ emissions by 190,000kg per year, the equivalent of 15,000 single truck trips covering the same distance.

Switching energy sources

The E-Pusher’s zero-emission energy containers can switch energy sources depending on the circumstances and client’s preferences, and Kotug says the modular approach to construction and “circular building” principle implies the vessel has an eternal lifespan as every single part can be replaced, adjusted or removed, including the energy source.

Construction time is claimed to be reduced by more than half compared with traditional vessels.

The series has three models: S, M and L, ranging from 9m to 22m in length. The smallest ‘S’ model, also known as the Kotug CityBarge, is also in operation where with partner Circle Line Logistics, a CityBarge is deployed for various projects in the Netherlands, including at Amsterdam, Leiden, Rotterdam and Utrecht.

With a draught of just 45cm the vessel can navigate shallow waters and low bridges, making them suitable for water transport in historic city centres and a “natural alternative to road transport”.

Based at Stellendam on the south side of the Haringvliet and in the province of South Holland around 12km south of Port of Rotterdam’s Maasvlakte complex, Padmos was established more than 90 years ago. Stellendam is home to an intense cluster of maritime-related businesses, including Damen Maaskant Shipyard.

“Our shared vision for sustainable maritime solutions drives this partnership, and we are excited about the transformative impact these vessels will have on the industry,” said Padmos CEO Leon Padmos.
