Author: Daniel G. Teleoaca – Marine Chief Engineer The beating heart of a ship is its main engine, and just like any hardworking engine, it needs a reliable air cooling system to function efficiently. This is where the ship’s main engine air coolers, come into play. Understanding the Why: Hot Air, Less Power There are…
Marine engines are the heart of any seafaring vessel, powering them through the vast expanse of the ocean. Ensuring their optimal performance is crucial for the safety and efficiency of maritime operations. One vital aspect of marine engine maintenance is monitoring and interpreting crankshaft deflection measurements. What is crankshaft deflection? Crankshaft deflection refers to the…
In the marine environment, it is essential to have a reliable source of power. Diesel generators are mainly used to provide power to ships and other marine vessels. During a vessel voyage, depending on power requirement (during maneuverings, canal transit, shallow waters, using bow/stern thrusters etc.) the engine crew need to run more than one…
Marine fuel injectors are critical components of an engine’s fuel delivery system, responsible for precisely atomizing fuel and delivering it to the combustion chamber. Over time, these injectors can become clogged, worn, or develop leaks, resulting in decreased engine performance, reduced fuel efficiency, and potential engine damage. In this blog article, we will explore the…
Oil mist detectors are devices that are meant to protect large diesel engines of all applications against serious damage originating from crank-drive bearings or piston components overheating. In case of “Visatron” oil mist detector, the atmosphere of the crankcase compartment is continuously drawn out by means of header pipes sampling system from each…
When the engine is running, the air in the crankcase has the same types and amounts of gases as the air around it. However, there is a heavy shower of coarse oil droplets that are thrown all over the crankcase when the engine is running. If there is too much friction between the surfaces that…
Two-stroke bearings are mainly composed of aluminum or tin-based alloys, allowing the bearing to bed and transfer the load over a broader area. If the bearing surface experiences excessive stress, the bearing shell will normally continue to function as the load is distributed across a greater area. As a result, most white metal fragment detection…
The emergency diesel generator is a self contained diesel engine driven electrical generator set, which is located in a separated room with access from deck. Usually the generator is the self-excited, brushless type and can be set for manual or automatic operation. Auto will be normally selected, with the manual setting being used for testing…
