Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME) today announced that it has marked 50 units of deliveries of its bunker-saving retrofit propeller since 2013.
MHI-MME highlights that the retrofit propeller was designed for slow steaming conditions, limiting engine load, and boosting fuel efficiency.
"Moreover, MHI-MME applies the design for the retrofit propeller to Mitsubishi Advanced Propellers (MAP) Mark-W, which propeller was launched in 2010 and can improve the propeller efficiency without sacrificing cavitation margin," the company adds.
MHI-MME says its mainly supplies retrofit propellers to large container carriers, as well as LNG carriers, and tankers.
The delivery record includes not only Japanese ship owners' but also overseas ship owners' projects
"The delivery record includes not only Japanese ship owners’ but also overseas ship owners’ projects," the company notes.
"Additionally, MHI-MME carries out the evaluation of the propeller efficiency improvement after propeller retrofitting and confirmed that the propeller efficiency improvement in a certain vessel reached about 8 percent, up to the limitation of engine load."
Last month, MHI-MME announced that it had completed the retrofit of new technologies for the use of low sulfur fuel on 80 liquefied natural gas (LNG) carriers.
