EST-Floattech delivers 2MWh system to WT RASA

3 juni 2026

EST-Floattech announces the successful delivery and commissioning of its maritime battery systems onboard the newly built fully electric waste tanker RASA and two electric-hybrid pilot boats. Baltic Workboats has delivered all three vessels to the Port of Klaipėda, marking another important milestone in the transition towards more sustainable and future-proof port operations in the Baltic region and another successful collaboration for EST-Floattech with Baltic Workboats.

The vessels combine proven maritime engineering with advanced electric and hybrid propulsion technologies, supporting the Port of Klaipėda’s ambition to reduce emissions, improve operational efficiency and modernise its fleet for long-term environmental performance.

2 MWh Battery System for Fully Electric Waste Tanker RASA

For the fully electric waste tanker RASA, EST-Floattech supplied a 2 MWh Octopus Series battery system. Designed to operate reliably under demanding harbour conditions and continuous duty cycles, the system enables the vessel to operate for up to 10 hours without charging, ensuring reliable performance throughout full working shifts. EST-Floattech’s team focused on the system being able to support the critical requirements for utility vessels operating in port environments.

“Projects like WT RASA demonstrate that even vessels with demanding heavy-duty duty cycles can successfully transition to zero-emission operations when the energy storage system is designed accordingly,” said Walter van der Pennen, CCO at EST-Floattech. “Reliability and predictability are crucial for any vessel, but especially essential for harbour operations. We are proud that our Octopus Series battery technology contributes to the efficient and emission-free performance every day.”

In addition to preventing emissions, the fully electric operation of WT RASA significantly reduces noise levels within the harbour area, contributing to a cleaner and quieter working environment.

“We are pleased to have partnered with EST-Floattech on the delivery of WT RASA,” Arro Truumees, Project Manager at Baltic Workboats. “The combination of our proven shipbuilding expertise and reliable battery technology of EST-Floattech has resulted in a future-ready vessel capable of meeting the operational demands of the Port of Klaipėda.”

Battery Systems for Electric-Hybrid Pilot Boats

In addition to WT RASA, Baltic Workboats has also delivered two electric-hybrid pilot boats. The vessels are equipped with battery systems with a total capacity of 240 kWh. The configuration allows the vessels to operate in fully electric, hybrid and direct diesel modes depending on operational requirements. The battery system enables speeds of up to 10 knots in electric mode and a range exceeding 15 nautical miles at 7 knots.
