There are a number of moving parts and machines on a ship that is necessary to keep it moving. Learn about the different types of engines you will find, including main propulsion plant and auxilliary power generators. Also learn about the onboard electrical systems crucial to carrying out basic functions such as control, communication and navigation. These are all essential elements in Marine Engineering.
If it is only the love triangle that you are familiar with, just read this article to know more about the flammable fire triangle in relation to Inert gas systems on board ships. After all the chemistry of both is symbolically related to fire!!!
Learn about the various methods used to replace air-hydrocarbon mixture with inert gas and vice versa on board ships as well as general cargo tank atmosphere control policy.
Apart from the cylinder lubricating system of marine diesel engines which requires a separate arrangement, the other parts are lubricated by the crankcase lubricating system described in this article.
Lubricating oil is comparable to lifeblood in the arteries of a human body. It must therefore be ensured that the lubricating oil used has required properties which are maintained over a period of time.
A crosshead bearing is used in situations where motion has to be transmitted between two components, wherein one of them has rotational motion while the other has linear to and fro motion. Lubricating under these circumstances could be quite challenging.
Some of the most arduous conditions for lubrication exist inside the cylinder liner where the lubricating agent would be subject to highly corrosive environment. Just learn how this situation is tackled in large marine diesel engines.
Cylinder lubricators supply oil to the accumulators and the lubricating quills present on the cylinder liner as we have seen earlier, but this article explains the detailed construction and working of an IVO cylinder lubricator of a specific type
The motion between a shaft and a bearing is of purely rotational type and this poses a problem of introducing a film of lubricating fluid between the two surfaces under varying conditions of load and speed.
A marine diesel engine consists of various components which are in relative motion which is of different types such as rotary, oscillatory or sliding. Lubrication is very important otherwise these components would simply wear out and cause damage. Learn about lubrication in marine engines here
Indicator diagrams are indicative of the power generated within engines and are a useful tool for marine engineers to know how well their engines are performing. Learn more about them inside.
Indicator Diagrams arent like most other gauge readings where you plug in the device and there you go. Here you need a lot of factors to be kept in mind and proper care on the part of the user for getting a true indication of the developed power

Rudolf Diesel invented the diesel engine but the marine engineers slog hard to keep it running on board ships. Just learn about the basics of diesel marine engines in this article.
Theoretical cycles are very useful in analysis of performance of internal combustion engines though the real engines may not strictly follow these cycles. Otto cycle is one such cycle. Read on to find out about the working principles.
