Zekatex YellowBee DC was used on the first European Union hybrid tugboat. Being a provider of two 200 kW DC/DC conveters (jokingly named van Boost & van Buck), together with our partner - the integrator Aspin Kemp and Associates, we successfully implemented the battery control of RT Evoltution tugboat. 

Starting from December 8, 2014 RT Evoltuion is fully operational at the harbour of Rotterdam. Godspeed RT Evolution!
