Vard Electro has secured an order with Siem Offshore to deliver a battery package for a vessel retrofit as the Norwegian shipowner proactively upgrades its fleet with hybrid power in pursuit of greener and safer operations with lower fuel costs.
The newly signed contract covers Vard Electro’s SeaQ Energy Storage System (ESS) with two battery packs and a DC link, which will be installed in the first quarter of 2022 on one of Siem Offshore’s subsea construction vessels lined up for work in the offshore wind sector. The system will enable the vessel to operate in fully electric mode with zero emissions while manoeuvring in harbour or other restricted areas and will deliver estimated fuel savings of up to 20%. The SeaQ ESS stores excess energy, either generated by the vessel or derived from shore connections with renewable power sources, to replace engines running on fossil-based fuels that drive propulsion and thruster systems. Battery storage will be used as a spinning reserve in place of generator sets, enabling the vessel to run on fewer engines with more optimal load while still maintaining the requirement for redundancy.
