INTRODUCTION TO THE TWO—STROKE MARINE DIESEL ENGINE

As the name of this film implies, it provides the required basic intro to the two-stroke marine diesel engines. It was prepared on the basis of the valuable input provided by Viggo A. Kjaer, professor at The RTU, i.e. Royal Technical University of Denmark. Today, the diesel engine propels half the tonnage of the whole world shipping.

Given good care, the diesel engine will provide 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 the exhaust and cooling water.

His routine inspection is taking him further down to the second platform with the intercoolers for charging air. Now, he has reached the bottom where his flashlight has revealed the return piston cooling oil behind the sightglasses...

POWERED WATERTIGHT DOORS (VIDEO)

When you join your vessel for the first time, note that it critically important for your safety to become thoroughly familiar with the particulars of the vessel, safety equipment on board, their design features and locations. One of the design features normally fitted to nearly all types of ships is the use of the powered watertight doors intended to protect the ship's hull 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 sort of reliable 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 means of the electric motors.

Watch this training video and you will get a full idea of what the shipboard powered watertight doors are, how and where they are commonly installed, what are the dangers associated with their operation in you fail to follow the correct procedure, and how to avoid the risks of getting trapped and harmed. This training will be best if watched with this booklet on same topic since they perfectly supplement each other.

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...

MACHINERY ALARMS AND PROTECTION DEVICES

The poor maintenance and incorrect operating of the shipboard machinery may result in a disaster. Such disasters can be really catastrophic, presenting immediate danger to the health of the people onboard, cause harm to the environment, etc. However, most of the accidents can be avoided. The present video training lesson is intended to acquaint the trainees with the shipboard machinery alarms and protection devices.

Every person engaged in the operation and maintenance of any machinery piece on board ship shall have a sound understanding of these devices as they play a critically important role in providing safe and effective operation. Of course, the main reference shall be made by the engineers to the user manuals and other documents accompanying the machinery items.

However, there is a need for some general introductory information that would allow future marine engineers to have an idea of how important these devices are; the experienced engineers, in turn, may use this video to refresh their technical knowledge. Needless to say that it is a duty of every single person in the engine room to pay close attention to the protective devices and alarms installed on the machinery.
