Shipping company Gearbulk has contracted Norwegian Electric Systems (NES) to provide the battery system for a new more efficient crane to be installed on board the general cargo vessel 'EMU Arrow' in place of an old gantry crane.

Gearbulk MD Ketil Andreassen said: "Gearbulk has actively advocated for increased global regulations of CO2 emissions in the shipping industry. This crane conversion, along with the installation of a containerised battery system, is one of many activities we undertake to both ensure an even more efficient running of our fleet, as well as reducing our impact on the environment to a minimum.”

Under the contract, NES will act as system integrator and deliver the battery system to the new jib crane, including the container and the battery charging system. The gantry crane in question is currently powered by three diesel driven auxiliary engines. Through installing a battery system housed in a container,  the new JIB crane can be operated by only one auxiliary engine – in combination with the battery. The battery will enable the vessel to benefit from the peak shaving effect, as the auxiliary generator will be able to run continuously at optimised load. As an added bonus the battery will be recharged by utilising the return power during cargo operation.

"Hybridisation of the new crane is a highly efficient method of both reducing operating expenditure and harmful emissions to air. Particularly local particle emissions will be reduced when you run one instead of three auxiliary diesel engines, but fuel consumption and CO2 emissions will also be reduced significantly,” said Stein Ruben Larsen, SVP sales, NES.

NES, which is a subsidiary of HAV Group, will design, assemble, and test the systems at its headquarters at Godvik in Norway. The battery system and the new crane will be fitted at the vessel's next schduled drydocking, most likely to be mid 2022 when EMU Arrow will undertake her five-year classification survey.

 “We are delighted that Gearbulk has chosen our battery technology to realise significant cost and environmental benefits. Shipowners and the supplier industry share a common responsibility to make the shipping industry greener, and this crane hybridisation initiative is a small but meaningful and profitable step towards this,” said NES MD Geir Larsen.
