Wärtsilä’s energy saving propeller cap that delivers average fuel savings of 2 per cent has been listed in the Vancouver Fraser Port Authority’s 2019 EcoAction program. Vessels calling at the Port of Vancouver using this technology will benefit from a 23 per cent discount on harbour dues.
The technology, EnergoProFin incorporates fins that rotate together with the propeller. This reduces the cavitation caused by the hub vortex of the propeller. It also reduces the energy losses caused by the flow phenomena around and behind the propeller boss, thereby increasing overall propulsion efficiency while lowering fuel consumption.
The Port of Vancouver’s EcoAction program provides harbour dues discounts to vessels that meet best practices in air emissions and underwater noise reduction, as well as other environmental impacts.
EnergoProFin has a payback time of less than one year and is optimised to fit the vessel’s specific operating profile. Wärtsilä will offer vessels fitted with the technology a certificate to enable customers to take advantage of the harbour dues discount. To date the technology has been installed on more than 350 vessels.
“The Wärtsilä EnergoProFin is designed to deliver both energy efficiency and environmental sustainability for ship owners. Our listing in the Vancouver Fraser Port Authority’s EcoAction Program is an honour that supports Wärtsiläs ‘commitment to cleaner, safer, quieter, and more efficient shipping,” explained Anton Voermans, manager hydrodynamics, Wärtsilä Marine.
