Once the air start is reversed, the engine will start as detailed for the ahead start. When the bridge telegraph is placed in Stop, the fuel is prevented from injecting as the fuel pump puncture valves are energised. Frictional grip is the usual method of crankshaft construction for built-up crankshaft. a chief engineer of a fifth class plant; or; a shift engineer of a fourth class plant. MAN B&W recommend that: The effective lubrication of the cylinder liner and piston assembly requires a constant lubricant feed over the whole liner surface, and that piston movement will generate the oil pressures required to separate the surfaces. Microseizure is caused when the liner and piston ring material is pressed together causing localised welding of the material in the absence of sufficient  lube oil. One of the common areas of overheating is the various bearings within the crankcase. The detuner will change the stiffness of the shaft and hence the natural frequency, thus separating the excitation frequency from the component’s natural frequency, whereas the damper will absorb the vibration within the shaft, reducing the effects of the torsional vibration. Low air pressure at engine manifold. The causes are insufficient oil and/or excessive cylinder pressures causes heavy ring/liner contact forces. X. If there are any defects at this joint, then the resulting stress concentration would trigger a crack and possible shaft failure. MEO Class 1; MEO Class 2; MEO Class 4; MMD – Nautical. Once the engine is turning above the starting speed, the air is closed and fuel is admitted.

I sail with one of the leading shipping companies as engine officer. This will admit starting air to the engine. Fatigue cracks can grow faster when the material is harder, as the dislocations in the metal concentrate the stress on a smaller area of the material structure, hence any hardening of the crank pins must not be applied to the highly stressed radii areas. This could indicate that the air compressors are either not working or excess air is being used. The physical movement of the fuel linkage would be checked, and any mechanical friction reduced by lubrication. The steam condenses producing both water, and a vacuum (when the water seals the pipeline from the steam supply). Marine Uniforms. The following brochures contain oral questions. These doors will open when the pressure rises above 0.02 – 0.1 bar, and prevent the over-pressure of the engine structure. The action of the fuel linkage would be checked during the start sequence. Defect growth from a small surface defect into a crack that propagates through the shaft material require high levels of stress. When the bridge telegraph is moved to  an ahead command, the air start and fuel cams are placed in the required direction, and the start command is given. Academic Papers; Uniforms. A person using the services of a professional person or organization. A Guide to Welding Electrodes on Ships - Part 2. A. monel The size of this radius will significantly influence the local stress levels, and should be closely monitored during crankshaft construction, and possible crankpin surface repairs by grinding.

The second event is the ignition of this white mist by either the same or another hot spot within the crankcase. A Guide to Understanding New Designations in AWS Filler Metal Classifications. The resultant white mist is within the explosive range, and is thus flammable. For more information, select what you need to apply for below. This torque variation is further compounded by the arrangement of the firing order of the crankshaft. The doors also perform the added function of preventing fresh air ingress into the crankcase where hot burning gases are present, by the quick closing action of the relief door. In modern marine 2-stroke diesel engines, _____ is sometimes used as a coating on the underside of the exhaust valve disc, to reduce the rate of hot corrosion. Marine Engineer Class 1 – Guidance for certificate of competency Page 2 of 16 . In this condition the torsional vibration of the shaft increases greatly, and will impose very high shear stress on the crankshaft.
