Diagnosing Causes of High EGT in Marine Engines There are several common reasons for high exhaust temperatures in marine diesel engines, but MOST causes can be attributed to a scavenge fire and/or a defective fuel valve, both of which are caused by a fuel system fault.
Parts of Ships - Guide to Component Descriptions Ships come in various descriptions and have hundreds of thousands of components, but there are a few parts that are common to all ships. In this guide, you can learn about how the basic parts of ships have evolved over the centuries.
Ship's Systems and Controls Numerous different ships systems and controls being maintained by engineer officers are used on all types of vessels today. These consist of engine room systems such as lube oil, fuel oil, and seawater, along with deck officer's roles such as cargo recording and navigation.
The Production, Handling, Storage, and Use of Marine Fuels Marine fuels and fuel handling are a common part of a ship’s engineers routine from taking on bunkers to ensuring the fuel is kept at optimum temperature, and as free from contaminates as possible, for use in the main engines or boilers.
The Charge Air Cooler in Diesel Engines The charge air cooler is an important device fitted in all turbocharged diesel engines to reduce the temperature of the charged air before its entry to the engine in order to increase the efficiency of engine. This article deals with purpose, location, and maintenance of charge air coolers.
Main Engine Layout Familiarization - B&W Engine Room Layout The ship’s engine room watch-keeping engineer must be familiar with main engine layouts, including their components optimum operating pressures and temperatures.
This familiarization should include a B&W engine room layout, as this is a modern, popular two stroke marine diesel engine.
Causes, Control, and Prevention of Scavenge Fires Scavenge fires are caused by oil igniting at the combustion air inlet ports within the scavenge spaces on main engine diesel engines. They are frightening and dangerous, but they can be avoided by carrying out good watch keeping duties and regular maintenance of the fuel system and fuel injectors.
Firefighting Equipment in Ship's Engine Room Ships engine rooms are susceptible to fires and explosions, as well as the engines themselves. However, there is firefighting equipment in a ships engine room to combat these hazards, such as hand held fire extinguishers and seawater hydrants/ hoses; CO2 or mist injection being used in engine spaces
