Battery System for Hagland’s new hybrid self-discharging coaster enables zero-emission port calls

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 Norwegian newbuild: the third Hybrid Coaster for Hagland, currently being built at Royal Bodewes shipyard and due for delivery halfway 2023.

EST-Floattech’s battery system enables the 5,000 DWT self-discharging bulk carrier to make zero-emission port calls. The vessel, one of a series of three, 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.

Proven, DNV-certified batteries
For this project, EST-Floattech deployed its proven and 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. Note that to prevent any delivery hick-ups, EST-Floattech has all delivery-sensitive components in stock, enabling fast assembly and production for on-time delivery.

Walter van der Pennen, Commercial Director at EST-Floattech, states: “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. This will lead to more and more hybrid and even electrical coasters in the coming months and years. We are grateful for the trust that Hoogendijk and our end-clients have put in us to arrange for a safe, long-term power solution for this vessel. With this hybrid coaster Hagland is clearly a forerunner in the market and we are proud to be part of that process.“

The newbuild, the third in a row, will not only sail in zero-emission mode in port, it will also reduce noise and emissions during sailing. According to Hagland their 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. According to Hagland, the new vessels will make their fleet the most environmentally friendly in this segment.
