De-rating of prime mover reduces fuel consumption In today’s environment of slow steaming, a permanent engine reduction can increase remarkably the economy of existing vessels and reduce the fuel consumption under these new engine load conditions. Main engines are normally designed for a specific high speed. However, for Slow-Steaming another Power-Speed-Course is decisive. A throttling of the engines reduces the engine specific maximal continuous power (MCR) and with this, the designed maximal speed of the vessel permanently. This leads to a higher economy with lower specific fuel consumption (sfoc). MV Cap San Nicolas (9.600 TEU) in service since May 2013 Measures for throttling include the modification of the injectors, plates between crosshead and piston rod as well as a new set-up of the turbo charger. This means, that always the engines technical data have to be changed. In addition also cylinders can be cut-off - this has to be done in connection with a new torsional vibr... [More]
