We should run it withoutload for a period of time and check the FW ,LO ,exhaust gas all in normal condition. if found something abnormal we should solve them.6Ability to understand alarm systems1. We are informed that, if alarm occurs ,there are some problems need us to solve.2. almost all devices in engine room have alarm device to let us take a notice at it .3. if alarm occurs ,we should immediately solve take attention to it and solve it as quickly as possible.4. alarms can be classified as high/low(temperature ,pressure ,level),start failure, no power and so on.5. some times if we can not solve the problem by repair the devices ,we also can doubt that there is something problem with the alarm system 7Watchkeeping at Sea1Correctly completing the Engine Room Log Book1. Engine room log book contents all the data that should be take attention to when duty patrol .and we should make sure that all data in normal arrange.2. we can calculate the slip of propeller with the data of average RPM (or total RC of main engine) and distance observed by bridge and propeller pitch.3. we should calculate the consumption and remaining of all kinds of oil in the log book4. all works done everyday should be filled into the log book5. when the ship departures from or arrives at a place ,all flow meter value ,OHN time, engine test time ,telegraph test time and stand by time should be filled in .2Ability to understand alarm systems1.
