Marine Machinery, Engines & Controls
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.

Guide to Ships Components - Parts of a Ship
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.

Guide to 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.

Marine Fuels and Fuel Handling
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.

Marine Diesel Engines - Theory, Components, and Care
The invention of the diesel engine in 1893 has been attributed to Rudolf Diesel, a German mechanical engineer and inventor. This was an innovative internal combustion engine that was the fore-runner of today’s marine diesel engines used in ships worldwide.

Bronze Rudder and Propeller Resurfacing Techniques
Resurfacing of bronze rudders and propellers is required after the boat has been subjected to the ravages of seawater immersion. This causes several types of corrosion that along with flow induced damage leave the components badly pitted, necessitating a spell on the slips to remove them for repair.

Ship's Level Sensors - Types, Construction, and Use
Measuring the contents of a tank is a job which most mariners hate to do. For this reason, many gauges and devices have been produced for reducing the man hours of mariners. Read here to learn about the common different types and their construction with detailed pictures of each.

Calculating Fluid Flow Through Orifices and Mouthpieces
The article discusses expressions that are generally useful for determining the various factors involved with fluid flow through nozzles and orifices. The practical relevance is also demonstrated through an experiment.

Modern Ships Engine Equipment with Waste Heat Recovery Boiler
Marine diesel engines and engine rooms have changed a bit since I was a young engineer at sea in the 1960’s. Nowadays modern engines are designed to be more economical and emit fewer toxic exhaust gas fumes.

Controlling NOx in Marine Diesel Engines
Learn about the techniques of controlling NOx emissions in modern day ships and what companies are doing to ensure that pollution to the environment due to NOx is reduced.

Modern Electrical Propulsion system For LNG tankers
Electrical Propulsion systems are not new to the marine industry. However, the system was limited to passenger vessels and some hi-tech research vessels. Recent trends and developments in power electronics have paved way for more advanced and modern trends in electrical propulsion.
