CRP SYSTEMS PROVE THEIR POTENTIAL IN SERVICE

The hydrodynamic benefit of a contrarotating propeller (CRP) system over a conventional single screw propeller is an improved open water efficiency. Two pioneering retrofit installations of CRPs are described, both of which are claimed to have demonstrated potential energy savings of up to 16%. The first was the installation of a Mitsubishi asynchronous CRP system on the 1979-built 4,177 grt Japanese car carrier TOYOFUJI 5. The other was the retrofitting of an IHI prototype CRP system to the 37,800 dwt multipurpose bulk carrier JUNO. CRP systems developed by other companies are also noted.
