EST-Floattech batteries picked for Hagland’s hybrid bulker

Dutch maritime energy storage solutions provider EST-Floattech has been contracted by system integrator Hoogendijk Electric to design and deliver the complete battery system for a hybrid bulk carrier ordered by Norwegian shipowner Hagland.

The ship is currently being built at the Royal Bodewes shipyard and is scheduled for delivery in 2023. It is the third in a series of three eco-friendly self-dischargers ordered by Hagland.

EST-Floattech’s battery system enables the 5,000 dwt self-discharging bulker to make zero-emission port calls.

The vessel will also sail in full-electric mode, for example in environmentally sensitive environments, such as in fjords or near-coastal communities. When there is no shore connection available the battery system also allows for zero-emission discharging of the transported bulk cargo.

During long-distance transits, the system allows for peak shaving via the electric motor and generator (aka the PTI/PTO). The batteries can be charged during transit or in harbour via the shore connection.

For this project, EST-Floattech deployed its DNV-certified Green Orca battery system. The system, including battery management software and control units for enhanced safety, was optimised for the ship’s operational profile in close cooperation with system integrator Hoogendijk Electric, responsible for the complete onboard electrical installation.

“It is interesting to see changing market demand as part of the energy transition. It is clear that our industry is evolving towards a more environmentally friendly mindset, partly driven by external regulations, but also by developing insights within maritime companies themselves,” Walter van der Pennen, Commercial Director at EST-Floattech, commented.

“This will lead to more and more hybrid and even electrical coasters in the coming months and years.“


The newbuild will not only sail in zero-emission mode in port, but it will also reduce noise and emissions during sailing.

According to Hagland, its new coasters will reduce CO2 emissions by 40% and NOx emissions by about 90%, compared to older vessels in their fleet, which will be replaced.

With EST-Floattech’s battery-hybrid system, the ship complies with IMO TIER III requirements.

Hagland’s new vessel programme is supported by ENOVA SF (the Norwegian Ministry of Climate and Environment’s organisation aiming to reduce emissions and develop energy and climate technology) and the Green Shipping Programme for fleet renewal. Hagland claims that the new vessels will make the company’s fleet the most environmentally friendly in this segment.
