The aim of onboard training of apprentice engineers in the training ship is to support and enhance fundamental knowledge and ability to have both theoretical and practical skills. This diversity in education and training improve the capability to handle problems in a crisis and build-up the feeling of confidence so they can effectively accomplish their assigned tasks in special circumstance like those onboard. Therefore this study suggests some remedies for qualitative improvement and guidance of onboard training ship for apprentice engineers to achieve the aims of onboard training to foster talented marine engineer officers with professional knowledge and leadership.

Put Investigation on the energy saving method using inverter driving for cooling pump at MMU training ship Myeong-Hwan Lim † ․Byong-Won Ahn*․Bu-Gi Kim** Abstract：The ships have a lot of electric machinery needed to supply electricity from the moment of launching coming out of dry dock to docking at jetty. Thus, the ships always have to use alternator and electric machinery that has low efficiency under the low load. Many government service ships like the MMU training ship have been spending lots of time at jetty rather than sailing at sea. These ships are operated under the condition of low load due to the operation of basic machinery at jetty and electric machineries are driven with the status of low efficiency. This paper would suggest the energy saving method for these ships. The investigation describes that shore connection is a great asset to these ships and that the flow rate control by adjusting revolution with the adoption of inverter is better than flow rate control by using throttle valve to save energy. The result is based on the investigation of cooling pump at MMU training ship. Key words：Saving energy(에너지 절감), Inverter(인버터), Cooling water pump(냉각수 펌프), Training ship(실습선)
