BASIC KNOWLEDGE OF ENGINE ROOM ELECTRICAL EQUIPMENTSAFETY PRECAUTIONS DURING ELECTRICALMAINTENACE:Give as many precautions as you can indentify:1. Make sure the power is off, if have control fuse remove it;2. Work areas should be well lighted, and keep working area clear;3. Ware safety PPE, and pay attention at this work at any time;4. Make sure to make notice like “MANAT WORK, DO NOT OPERATE.” Toshow other People that sb. Is working.5.Tools should be will insulation we can measure all the engine room system workingsituations, failure alarm and parameter from this system. We can control theengines better.List out various components and give brief descriptions-Alarm system _to make us know that some system is abnormal-Alarm record system- to record all the abnormal at the timelet us know-The display screen to show us all the systems working situations failure andparameterSINOCREW MARITIME SERVICES PTE LTD15Identify all sensors connected to ME safety system-M/E speed sensor-M/E L.O pressure sensor-Exhaust valve air spring lowpressure sensor-Crosshead L.O pressure sensor-Jacket C.F.W.in and out temperature sensor-Scavenging Box fire sensor-Cylinder oil non-flow alarm system- JacketC.F.W pressure sensor-EX. GAScylinder outlet temperature sensors-Piston cooling oil cylinderoutlet temperature sensors-thrust bearing L.O outlet temperature sensorREMOTE TEMPERATURE INDICATORAND CONTROLUnderstand basic concept of the system.-To monitor the working condition of the m/e system,The temperature signals,which come from the local temperature sensors of the machineries, go throughtransmitter box. We can control and monitor the temperature by the computers andmonitor them on the indicators.List out various components and give brief descriptions-sensors: all the temperature sensors which connect to the machineries-transmitter box-temperature indicatorsSINOCREW MARITIME SERVICES PTE LTD16REMOTE PRESSURE INDICATORAND CONTROLREMOTE LEVEALINDICATORUnderstand basic concept of the system.-The level signals, which come from the local level sensors of the tank, go throughthe transmitter box. We can control and monitor it by the computers and monitor itby the indicators.List out various components and give brief descriptions-Transmitter box-E/R control console-Ballast control console-Level indicator monitoring panelUnderstand basic concept of the system.-The pressure signals, which come from the local pressure sensors of themachineries, go through transmitter box. We can control and monitor the pressureby the computers and monitor them on the indicators.List out various components and give brief descriptions-sensors: all the pressure sensors which connect to the machineries-transmitter box-pressure indicator monitoring panelSINOCREW MARITIME SERVICES PTE LTD17LEVELALARMUnderstand basic concept of the system.-The level alarm sensors are activated when the water or oil level is high or low,then the signals go through the transmitter box. After that the alarm signal horns inE/R will be activated and the alarm will be showing on the monitors.List out various components and give brief descriptions-level alarm sensors-transmitter box-alarm signal hornsALARMAND MONITORING SYSTEMWith help of a block diagram, give brief explanation of how sensors areconnected, monitored and alarm activated in case of abnormality.-When the abnormal comes the sensor give the date signal to the transmitterandgive then give To the CPU the system will give the alarm to the monitor systems,give a abnormal buzzer and alarm light.Identify all components-Sensor- measure the signal-Transmitter- transfer the signal from local to the CPU-CPUcompare the signal with the setting and given the alarm signal- Monitorsystem- to show the abnormalSINOCREW MARITIME SERVICES PTE LTD18STORESAND SPARESStore procurement procedure:-When the spares coming check the quantities number size of the items with thereceived item list to make sure all the items are right ,and check any items alreadydamage or not. Put the new receive items inside the store.Store Inventory management-Three month: check all the stores quantities to make sure what need to order ornot, how much need to order. How many spare left. And which one order use ormissing.SINOCREW MARITIME SERVICES PTE LTD19Duty of Elect.
