Author: Daniel G. Teleoaca – Marine Chief Engineer The world’s oceans are vital for global trade and transportation. But with great maritime activity comes a responsibility to minimize environmental impact. One key technology helping achieve this is Exhaust Gas Recirculation (EGR) for vessel engines. Let’s dive deep into the world of vessel engine EGR systems….
Author: Daniel G. Teleoaca – Marine Chief Engineer Imagine a giant, powerful engine churning beneath the waves, propelling a massive ship. While all seems smooth from the outside, within the engine lurks a hidden enemy: torsional vibration. What are the torsional vibrations and who cause them on a marine engine? The culprit behind torsional vibrations…
In the world of marine engineering, hydrostatic locking is a term that sends shivers down the spine of every professional. It’s a potentially catastrophic problem that can lead to severe damage to engines and, in some cases, endanger the entire vessel. In this article, we will delve into the causes of engine hydrostatic locking, how…
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…
I believe that many of you, have heard in the last couple of years about running the main engine at low load or slow steaming due increasing fuel price and lately due more stringent environmental regulations. The 2-stroke engines are designed and optimized for operation in the load range above 60 % CMCR, but is…
Onboard vessels, modern power management systems make it less likely for power to go out for no reason, but engineers must be familiar with the specific procedures, where to find the instructions and procedures, and ready to act in case of automation failure. In case of a problem with power main diesel generators or in…
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…
