HHI introduces new fuel saving propeller attachment

HHI introduces new fuel saving propeller attachment
South Korea’s Hyundai Heavy Industries (HHI) has put its new fuel saving propeller attachment device into service on a LNG carrier, allowing the ship to reap fuel savings of up to 2.5%.

The fuel saving propeller attachment device, named Hi-FIN, is an attachment to the hub of the propeller, allowing it to generate countering swirls to offset the swirls created by the propeller itself, and thus improves propulsion efficiency.

The energy-saving device has been installed on the 162,000 cu m LNG carrier ordered by Maran Gas, and fuel saving of up to 2.5% is expected compared to the same type of vessels without the Hi-FIN.

“If the fuel saving ratio is calculated on the basis of an 8,600 teu containership, the owners or operators of the containership can save about $750,000 per year or $19m for 25 years, an estimated lifetime of the ship,” HHI said.

HHI has won orders of Hi-FIN for over 30 ships to date, and it expects more orders on ships including VLCCs, LPG carriers and containerships.
