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...

Powered Watertight Doors (Video)

   When joining a ship for the first time, it is very important to become familiar with its particulars, safety equipment, design features and their locations. One design feature fitted to many types of vessels is the use of powered watertight doors to protect the ship from the risk of flooding in case of the grounding, collision or structural damage. When closed, these doors become part of the ship's structure acting as a barrier for the flood water, and their strength is vital - they are built from the heavy steel requiring them to be moved by hydraulics or powered by electric motors... This training will be perfect if watched with this booklet on same topic.

Introduction to the Two-Stroke Marine Diesel Engine

   As the name of this film imples, it provides the basic introduction to the two-stroke marine diesel engines. It was prepared in co-operation of Viggo A. Kjaer, professor at The Royal Technical University of Denmark. Today, the diesel engine propells half the tonnage of all the world shipping. Given good care, the diesel engine provides a maximum of effect on a minimum of oil consumption. The engineer is here for that, at the moment he is checking the temperatures of exhaust and cooling water. His routine inspection takes him further down to the second platform with the intercoolers for charging air. Now, he reaches the bottom where his flashlight reveals the return piston cooling oil behind the sightglasses...

Shell and Tube Type Heat Exchanger

   Here is a very short but still very useful training video explaining the basic principles of the shell and tube heat exchanger. In fact, it is the animation which allows to see the whole process of exchanging heat starting from the point where sea water enters the heat exchanger. It will definitely be of some interest for the students of marine engineering and any persons dealing with the day to day operation, maintenance or repair of the subject machinery piece on board ships.

Heat Exchanger Principles

   IHRDC Video Library for Production Operators. The training video explains the basic principles of heat exchanger operation... You know, when the engines are running, they can really get hot. So, in order to keep it running, we need a way to remove the heat. That is where the radiator comes in. As the engine runs, the coolant stored in the radiator, circulates through the engine, picks up heat and then returns to the radiator...
