BASIC MARINE ELECTRONICS COURSE

Welcome to this basic marine electronics course. Let us see what we are going to learn in this course. The first part of the course is about the sensors, including wind sensors, speed sensors, depth sensors and all others installed on board – what are the differences between different technologies used to build the sensors, how we are supposed to install and maintain them.

The second part of the course is devoted to the protocols and networks – so, what are the differences between different protocols used in marine electronics, why is one better than the other, what is the wiring to connect electronics, and how can the products by the different manufacturers be compared.

The third part is about the screens or displays – where to install those, differences between screen building technologies etc. After that we will move to the processors – what functions are calculated inside the processors, what is the mathematics and logic behind it, and why are they so important.

The fifth, and last, part of the course is about the onboard computers and onboard navigational software – how can we integrate our electronic systems in the computer and navigation software, why it is important and why and how it make our system a complete system, allowing us to sail safer and faster.

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...

REEFER VIDEO TRAINING

This is the officially distributed MSC training course... The unit consists of five major sections - the compressor section, condenser section, evaporator section, control box section, and the electronic partflow section. The compressor section includes compressor, discharge valve, suction valve, high pressure switch, pressure regulator valve, stepper suction modulation valve fitted on the new units which replaces the suction modulation valve and the suction solenoid valve for the older ones, quench valve and supply air sensors.

The units are fitted with two supply air sensors - one sensor is needed for recording data while the other one is for controlling cargo temperature. Then there are power cabling and unit identification plate, receiver tank, king valve, filter dryer, condenser section including air cool condenser coil, condenser fan grill, fan and motor. The condenser fan causes the air to be drawn from the bottom of the condenser coil and to be discharged through the condenser fan grill.

The evaporator section includes access panels, heaters, fresh air vents; the purpose of fresh air vents is to provide ventilation for commodities that require fresh air circulation. The vent must be closed when transporting frozen cargoes. To adjust the percentage of air flow, loosen the nut and rotate the disk to the desired percentage of air flow...

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.
