A VIEW INSIDE THE MARINE ENGINE

This short video was prepared in order to demonstrate the real internal arrangement of the typical marine diesel engine.

The authors had made an excellent attempt to produce a very short training video that would illustrate how the engine is constructed and how it actually operates. Only one minute long but so interesting.

For sure, will be appreciated by all people trying to improve their knowledge of the diesel engines, their constructions and processes taking place during their operation. You should agree, it definitely deserves attention.

CHEMICAL WATER TREATMENT

There are a great variety of ships at sea today whose many technical specifications of engineering installations. The one thing that is common to all of them is that they all require the use of water - one way or another. It may be used for steam production or engine cooling, or simply for consumption by the officers and crew. In fact, water will be used on board in considerable quantities.

Fortunately, there is always plenty of it available in the form of a sea water; they can pump it and use it straight away for washing the deck, for example. But if you try and use this water in a boiler, or for cooling your main engine, in a few days catastrophe will hit the ship - the boiler could blow up or the main engine get damaged. This is because sea water is contaminated by dissolved and dispensed solids, namely sodium chloride, calcium carbonate, magnesium carbonate and calcium sulphate.

These form deposits which can cause overheating and mechanical breakdown, making it unsuitable for use in boilers and in engine cooling systems, just like it is unsuitable for drinking by human being. that is why the cleaning and treatment of water on board the vessel is so important for the ship's efficient operation - and that is where chemical treatment plays a vital role by preventing internal corrosion and scaling formation...
