Generator Protection Devices have been discussed in this article and they are as follows: ● Over Current Inverse Time Relay OCIR ● Over Current Instantaneous ● Negative Phase Sequence NPS ● Current Differential ● Earth Leakage Relay ● Under And Over Frequency ● Lock Out Trip ● Reverse Power Trip ● Over or Under Voltage […]
Common rail fuel injection have been discussed in this article for marine engines whether main engine for propulsion or diesel generators. This kind of fuel injection system has its own pros and cons and will be studying this in detail as how this system works. Such kind of arrangement is already being used in RT […]
Crankshaft for marine diesel engines have been discussed in this article. They are of many types and is used as per the need for a particular type of requirement. After piston takes away the combustion forces developed during ignition, it transmits forces to crankshaft, and gives it a circular cyclic motion. The shaft and the […]
Main engine bearings lubrication is being discussed in this article and information about the lubrication of all the major bearings and type of lubrication happening between the surfaces. Here in this article we will discuss lubrication in following bearings: Main engine shaft Bearings or Journal Bearings or crank pin bearing. Crosshead Bearing Lubrication Crosshead guide […]
Diesel Generator Alarms and Trips have been discussed in this article, which are common among all the generators. We will take some of the major alarms and trips. Also we will give reasons for such alarms occurring and troubleshooting to be done. Following alarms we will mention HT Water Temperature High High Low Lube Oil […]
Crankcase explosion causes and prevention have been discussed in this article, with experiences of fellow Marine engineers. This explosion is a phenomenal which can lead to complete loss of propulsion power of the ship. As name suggest such explosion will take place inside the crankcase, and will have high intensity of explosion leading to damage […]
This article discusses about the crankshaft deflection and bearing clearance measurement in details. Both of the process is crucial for the any engine onboard. But here we will focus our approach towards the main engine only. But for crankshaft deflection related to generators is more or less same. Read this interesting article: Main engine crankcase […]
Exhaust Gas Boiler Fire causes and actions to be taken in such scenario are discussed in this article. If proper precaution and maintenance is done, such a scenario can be avoided easily. It has happened that fire have become so intense that it has lead to melting of the whole boiler. So we will divide […]
Marine engineering as a career have been discussed in detail all over this article. Also we will focus on what Marine engineering is all about and how much a Marine engineer earns. What is Marine engineering? Well the name of the profession is quite explanatory. Marine engineering deals with all technical related jobs at sea […]
