GNV marine operations director Antonio Campagnuolo said: “GNV is committed to investing in modern and advanced solutions to renew on-board systems and to improve the energy performance and consumption of our fleet.

“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.”

ABB’s chiller optimisation targets the substantial hotel load required for an HVAC system on-board passenger ships.

Based on a target set for chiller optimisation to save 10% of the energy used by chillers, pilot results cut power consumption on-board La Suprema by 18%.
