Norwegian Electric Systems (NES) has signed a contract with Havila for two new Quest-2 energy storage systems. The systems will be installed on board Havila Charisma, a Havyard design, HD833L, which was built at Havyard Ship Technology in December 2012, and on board Havila Foresight, an MT 60120 MKII, designed by Marin Teknikk and delivered in December 2007. Both vessels will be retrofitted with battery containers with an energy capacity of 625kWh and possibilities for extension to 750kWh. The Quest-2 system will be utilised in three different modes: transit/steaming, standby/harbour and dynamic positioning (DP). According to NES, the customer can now expect average savings of 15-20%, with 5-10% offered in transit mode, 20% in standby/harbour mode and 25-30% in DP mode. Specifically, in DP mode, the batteries will work as a spinning reserve, meaning the vessels will need only one running generator set. However, when extra power is required, the Quest-2 system can supply it. The future looks bright for NES with state-of-the-art products and systems that can compete internationally, said Jan Berg, EVP, business development, NES.
