Energy savings of over 18%have been achieved on board ferry La Suprema
Italian ferry operator Grandi Navi Veloci (GNV) has achieved over 18% energy savings on board ferry La Suprema.
It teamed up with ABB to complete a first-of-its-kind retrofit of a technology that optimises the performance of chillers used for heating, ventilation and air-conditioning (HVAC) systems on ferries.
“GNV is committed to investing in modern and advanced solutions to renew onboard systems and to improve the energy performance and consumption of our fleet,” said GNV marine operations director Antonio Campagnuolo. “Working together with ABB helps to achieve our goal of providing an efficient and safe transport service through important investments in energy-saving solutions of our fleet."
Based on a target set for chiller optimisation to save 10% of the energy used by chillers, pilot results cut consumption of power on board the ferry La Suprema by 18%. The results suggest the owner will save 70 MWh of power every month, adding up to annual savings of up to €77,000 (US$87,000).
Actual energy consumption was depicted in real-time via an online dashboard. The results from the optimisation solution consistently showed direct energy savings.
ABB said the technology draws on active monitoring on board and data processing ashore through a remote connection and only requires a local onboard controller to interface with the chiller control. Based on algorithms generated from real-time data, such as weather forecasts, active learning and 250 HVAC system variables, chiller energy use can be cut significantly without compromising on cooling capacity or indoor climate. All data analysis and energy saving calculations have been verified by independent analyst Into Trend.
ABB Marine & Ports Italy vice president Daniele Patuelli said “Our strategy envisages an electric, digital and connected future for shipping, and energy-saving solutions that help owners achieve sustainability benefits are a major milestone for this vision for the maritime industry.
