Swiss company Leclanché has been selected by Kongsberg Maritime to provide batteries for Cadeler’s F-class jack-up vessel installation vessel
The F-class vessel is being constructed in Qidong, China, by COSCO Heavy Industries. It will be fitted with what Leclanché described as "a third-generation, liquid-cooled Navius MRS-3 onboard battery storage system."
The battery system will be used for both spinning reserve and power regeneration during jacking and crane lifting operations, both operations that require high charge and discharge rates for which Leclanché says its energy storage solution "is ideally suited."
The MRS-3 battery system will help the vessel to operate safely while in dynamic positioning mode, by ensuring there is a spinning reserve and will provide a back-up, uninterrupted power source.
The Swiss company said the MRS-3 will enable the installation of more wind turbines by reducing downtime. “It offers more efficient operations, as the energy used during turbine installation is partially recharged into the battery by recovering the braking energy during jack-down,” said the company.
Leclanché vice president marine Guillaume Clément said, “Our Navius MRS-3 system is the most reliable and safest battery storage system on the market. We are delighted that our systems continue to be recognised as market leading as demonstrated by our successful bid to provide a 5.2-MWh battery system to Kongsberg Maritime.
Kongsberg Maritime technical product manager energy storage Stian Ramm said, “Kongsberg has partnered with Leclanché on more than 10 maritime installations, and we’ve come to know and appreciate its technology.
“Leclanché’s liquid-cooled batteries perform exceptionally well when supporting high charge and discharge applications, such as those required for the Cadeler jack-up. The system will also help the owner to maximise emissions reductions while experiencing the highest levels of safety.”
Leclanché will deliver the Navius MRS-3 system to the yard in 2025. The lithium-ion based system has liquid-cooling to increase its lifespan as well as an advanced battery active system.
The battery energy storage system uses a highly redundant structure with 46 battery strings.
Leclanché manufactures its lithium-ion battery cells, packs, modules and casings to German and Swiss standards at its automated manufacturing assembly lines in Willstätt, Germany, and Yverdon, Switzerland.
