Tanker Gets Bunker Saving Plastic-Based Main Propeller
A Japanese chemical tanker is the first merchant vessel to use a plastic propeller on its main propulsion system, reducing fuel costs, World Maritime News reports.
Japanese classification society ClassNK and Nakashima Propeller Co. Ltd. helped provide the carbon fiber reinforced plastic (CFRP) propeller for the Taiko Maru, owned by Sowa Kaiun YK.
The ship has already been using CFRP propellers for its side thrusters since September 2012, and the shipowner decided to add the same technology for its main propeller after noting their successful performance.
The material gives the propeller a strength at least equal to the aluminum-bronze composite usually used in propellers, but the lightweight composition allows for the use of smaller-diameter propeller shafts, reducing overall weight and allowing for the use of less fuel.
In sea trials, the CFRP propeller demanded 9 percent less horsepower than a standard propeller.
Class societies are increasing their focus on fuel-saving equipment to support rising demand among shipowners.
