Your email address will not be published. If the engine fails to start on air the following points would be investigated, and remedial action taken. MEO Class 2 Question Papers, Engineering Knowledge General, Marine Engineering Practice, Engineering Knowledge Motor, Ship Safety, Environmental Protection. Hence bearing temperature monitors could be used to indicate that a bearing is overheating and could be oil mist generation site. Low fuel pressure at the engine manifold. All air compressors would be started, and air usage restricted to engine manoeuvring only. Excessive crankshaft bending due to a main bearing failure, which increases the crankshaft bending stresses. The quantity of fuel admitted will depend on the position of the telegraph handle, i.e. This grip is subjected to the full torque of the engine output, and  hence subjected to high torsional stresses. Questions and Answers on Diesel Engines 1, Preparation for Arrival in Port Checklist, Fuel Injection Arrangement on Large Two Stroke Engines, Maintenance of Chain Drive – Marine Diesel Engines, Operation of Freshwater Generator with Jacket Cooling Water, Starting Air Line Explosion on Ships – Marine Engineering, International Shore Connection for Fire Fighting, Torsional Vibration in Main Propulsion Plant of a Ship, MEO Orals on Marine Electro Technology Function 5- Part 8, Describe how a fatigue crack may be initiated, Describe the events leading to a crankcase explosion on a main engine, Explain how a fatigue failure is identified, How a detuner or torsional vibration damper can reduce the effects of torsional vibration, how the risk of water hammer may be avoided, problems associated with effective lubrication of the liner and piston assembly, State how overheating might be indicated other than by mist detector, State how the severity of a crankcase explosion is limited, wear down in main bearings is critical to the condition of the crankshaft, What are the causes and effects of torsional vibrations in crankshaft, What is meant by the term critical speed and why it can be a problem on ships, Why oil holes are given large fillets in crankpins and journals, why the testing and treatment of boiler water is essential, Why total reliance is placed on frictional grip in conventional built up crankshaft on main engine, Measuring Fuel pump Lead on Marine Auxiliary Engine, Operation and Maintenance of Eductor on Ships, Insulation Resistance Tests of High Voltage Equipment, The level of chlorides is within acceptable limits (below 200 ppm) to prevent hard scale and pitting, The reserve of boiler chemicals within the boiler water is accepted (P Alk above 100 ppm, and Phosphate above 20ppm), Alkalinity reserve against boiler water space corrosion, Enough coagulant levels exist to minimise sludge build-up within the boiler, The strength of the boiler drum is maintained, Reducing the steam load and demand on the auxiliary boiler to reduce firing temperatures, Ensuring hotwell feed temperatures are at the recommended 95°C to minimise oxygen levels in the feed, Minimise blowdown of boiler water, whilst ensuring chloride level is not excessive, to avoid loss of the boiler chemicals, High combustion pressures, increasing the bending stress applied to each crankshaft throw. Academic Papers; Uniforms. Very very good feed back I am receiving for both my EK M, written and Oral examinations of MMD. Previous template Next. We will put them in a brochure with a link to you. Below is an IED unit 1 engineering quiz that is perfect for trying to see just how much one has been attentive in class. this post will help to build up a basic understanding and to become familiar to such question . Requirements. Love Dogs a lot. Meet medical, eyesight, sea service and course requirements. The shut down panel would be examined, and if a trip is active the cause would be investigated and system made operational. The physical movement of the fuel linkage would be checked, and any mechanical friction reduced by lubrication. Class IV Level ; New Management Level. Class IV Level ; New Management Level. 1. marine engineer class 2 exam questions is available in our book collection an online access to it is set as public so you can download it instantly. Thanks with best regards to you. marine-engineer-class-2-exam-questions 1/5 PDF Drive - Search and download PDF files for free. This could indicate that the air compressors are either not working or excess air is being used. Move away from the crankcase doors immediately, Reduce speed to slow, and ask the bridge to stop, When the engine has stopped, close the fuel supply, Lock engine room entry doors and keep away from them, Do not open the crankcase for at least 20 minutes after stopping the engine, and ensure that the oil mist detector alarm (or bearing temperature monitor) has reset. The critical speed of a shaft occurs when the shaft rotational speed is at or close to resonant conditions. Director General of Shipping, Govt of India. Defect growth from a small surface defect into a crack that propagates through the shaft material require high levels of stress. The evaporated oil then rises within the crankcase, and then condenses in a cooler part of the crankcase. This vacuum causes the water plug to be drawn into the closed end of the pipe with increasing velocity producing high impact forces on the pipework. Uniforms for India. Stop the LO circulating pump. These can be reduced by ensuring a smooth surface finish to all area where high stress is applied especially in the web/pin radii area, These should be minimised whenever possible, and the oil hole opening have wide and smooth radii.
