Nippon Marine, a member of Japan’s SENKO group, plans to install a Norsepower rotor sail with a tilting foundation on its 53,762dwt combination carrier Koryu to improve fuel economy and reduce greenhouse gas emissions. In a somewhat unique retrofit, the rotor will replace one of the nine-year-old ship’s deck cranes, leaving three cranes to serve the vessel’s five cargo holds.
Built in 2013, the Marshall Islands-flagged Koryu is used to transport copper concentrates from Chile to Japan as well as sulphuric acid from Japan, back to Chile for mining giant BHP and Japan’s Pan Pacific Copper.
The installation of the rotor will provide the vessel with ‘pushbutton’ wind-assist propulsion, as there is no reefing or crew attention, and will make Koryu one of the cleanest vessels in her category. JS
