Hyundai Heavy Industries (HHI) announced that it
recently completed the performance verification of its new fuel-saving
propeller attachment device, Hi-FIN, and expanded
the use of it to all ships.
The Hi-FIN is a pinwheel-shaped
attachment to the hub of a propeller allowing it to generate counter swirls to
offset the swirls created by the propeller itself, which improves propulsion
efficiency.
The HHI installed this new
energy-saving attachment on the 162,000 m3 LNG Maran Gas carrier of Greece in
April last year, it completed the requirement to be used on actual navigating
ships for a year.
The
vessel, equipped with a Hi-FIN,
can save up to 2.5 percent of fuel compared with the same type of vessels
without a Hi-FIN. Calculating the ratio on the basis of an 8,600 TEU container
ship, it can save about US$750,000 (817.28 million won) per year or US$19
million (20.7 billion won) over 25 years, the estimated lifetime of a ship.
Now
that it has confirmed the effectiveness of the Hi-FIN, the HHI has won orders to install
it on more than 30 ships.
The new
HI-FIN device
can be installed on broader types of ships, from LNG carriers to container
ships, very large crude carriers (VLCC), and LPG carriers.
An
official from HHI
said, “In the prolonged recession in the shipbuilding industry, we will improve
our competitive power to win orders by differentiating vessel performance,
including the improvement of fuel
efficiency.”
