Marine lube oil system or any lubricating oil system in particular works on four key types of lubrication; hydrodynamic, hydrostatic, boundary and elastohydrodynamic lubrication. Adequate lubrication of parts is required to avoid heat buildup and wear; thus playing an essential role in the working of ship machinery and marine diesel engine in particular. Many a … Read more Lubricating Oil System On Ship | Explained
Having correct lube oil properties is critical for the successful operation of machinery. They are used as a coolant, reduce friction, provide cushioning, act as a cleaning agent, protect components against corrosion and more. There are various grades and types of lube oil available; based on engine speed, working conditions, operations, specific requirement or regulations. … Read more Lube Oil Properties To Consider For Marine Engine
A crankcase explosion is a product of primary and secondary explosions occurring in the crankcase of the main engine. In fact, it is one of the greatest threats to safety on the ship. It happens primarily because of the ignition of oily mist present within the engine crankcase. While the source of mist and heat … Read more What Is CrankCase Explosion & How Do It Occurs?
An Indicator diagram is taken to access the performance of each cylinder unit for the ship’s engine. The idle diagram is then compared with the obtained one; that is taken at frequent interval. This helps us know of any deviation or irregularity in the combustion condition and its associated parameters inside the cylinder. This can … Read more Indicator Diagram | Its Types, Importance & Procedure
Who doesn’t want a trouble-free operation from its marine diesel engine; especially when a great deal of time, effort and money has been invested into it. The only stress engineers face during the watch keeping duties is to move the ship from Port A to B; without engine breakdown in between. So it becomes essential … Read more Common Engine Troubles In Marine Engine | Reason & Cure !
It’s not that easy to start marine diesel engine like on a push of a button in our car. Starting an marine engine require a series of checks and procedures to be followed; before the final go ahead. It’s the fuel, lube oil, starting oil, jacket water and interlocks which affects the overall starting procedure. … Read more How To Start And Reverse The Marine Diesel Engine
The marine diesel engine or ships main engine is the heart of the ship; responsible for its movement from place A to B. With all major loading and discharge schedule made in advance; any critical damage lead to huge loss of money and time. With main engine accounting more than 30% of the total machinery … Read more Ships Main Engine | Major Inspection & Overhaul
A ship or boat have limited maneuverability ( the ability to change direction ) with rudder and propeller. In congested waters, near port area’s and emergency condition a ship may be required to quickly move backwards. While the popular way to do is to take Williamson turn but the quickest and easiest way is to … Read more How And Why The Ship & Boats Are Reversed ? | Explained
For an idle six cylinder engine; the injection timing of all cylinders are timed according to the firing order. For an inline six cylinder engine a firing order of 1-5-3-6-2-4 ensures; that more power is produced without putting unwanted stress and opposing forces on rotating shaft. Normally, a compressed air of 20 to 30 bar is … Read more Starting Air Distributor – Definition, Construction And Working
Have you wondered why some vehicles release visible blackish exhaust while other’s not? The darkness or blackish nature of exhaust gases depends much upon the fuel atomization and fuel pump timing. Proper injection at set point of time will lead to complete combustion producing clean exhaust gas; while any deviation in injection timing results in … Read more Why And How To Check Fuel Pump Timing in I.C Engine
