Oil, fuels, lubricants, chemicals are the lifeblood of our modern industrial world. The cargo is pressurized but volatile. Within the hull of the ship, each tank is sealed to maintain the cargo quality and protect the crew, the vessel and the environment. But the cargo is also dynamic, its volume changes all the time, very obviously at loading and discharging, and less obviously through temperature changes and vaporization.
The volume of the tank is fixed, so changes in volume of liquids and gases within the tank must be accommodated, or they will translate into changes in pressure. Tank bulkheads are thin; they are designed to operate within tight parameters. Typically at commissioning they are tested with pressures of around a quarter-bar and a vacuum of less than 1/10 bar. The forces are massive, enough to disturb frames, bulkheads and decks, causing catastrophic failures, explosions, fire and pollution.
This video sheds light on the important aspects of handling pressures within the cargo tanks of the vessels. The information and knowledge gained when watching this video lesson carefully, will be of great practical use for the people working on board and can eventually result in prevention of the negative consequences caused by either under- or over-pressurization of cargo tanks.
This video training course was developed and officially released by maybe the most famous manufacturer of the shipboard air compressors. The contents is arranged in several video lessons covering such important aspects as installation of the pump, its operation on board, periodical technical maintenance, checking the screwed connections, changing oil, replacement of the air filter cartridge, dismantling, checking and assembling new valves, checking the coupling, exchange of the piston rings, and exchange of the gudgeon pins and associated gaskets.
The course should be considered mandatory for all people dealing with subject compressors when working on board. The attention to the details is remarkable. Everything is explained in a very simple way. In addition to that, note that the course will be very useful to the crew members on board ships with other air compressors installed since the physics of the process remain more or less unchanged.. It will be greatly beneficial to all students to have a close look into these video lessons as they are really good supplement to whatever can be read in the books or in the service, operation and maintenance manuals.
Watch this training video and you will have full information about the shipboard ballast systems. The ballasting and de-ballasting are considered one of the most important operations on board any vessel. There are many factors to be taken into account when performing those operations and failure to do that properly may result in the bad consequences. For example, the stability of the ship is directly connected with the daft which, in turn, depends on the ballast condition of the ship.
That is why due attention shall be paid to the stability aspects. In order to properly evaluate the ballasting operations we shall have a good understanding of how they are performed, and this is not possible without having a clear picture of the shipboard ballasting equipment. The key components of the ballast system are ballast pumps and piping arrangements including valves, and they are all controlled via the shipboard ballast control system.
The ballasting and de-ballasting are conducted either by gravity, i.e. using the natural forces, or, when that is not possible due to the position of the ship’s hull in relation to the sea water surface, by means of the pumps. This video will show all stages of the operations making it clear even for the beginners.
This is the official video training set developed by the specialists of one of the most recognized and world respected manufacturers of the diesel engines, including marine diesel engines.

The training set will cover all major aspects of those turbochargers and provide good and detailed instructions.
It will be very valuable to any person involved in operation, routine technical maintenance and repair of subject piece of shipboard equipment. It is highly recommended to the above categories of specialists. Taking into account the approach used by the authors of these training videos, it may be used even by the people servicing the turbochargers manufactured by the other companies, since the physics of the process an principle of design and operation remain more or less similar.
However, it will be particularly useful to the engine room team of the ships with the subject equipment installed on board. Make sure you have these training files downloaded and saved for the training and future reference whenever required as this is a truly indispensable source of good technical information.
This instructional video is devoted to the Mitsubishi MET-SC model of the turbocharger developed and manufactured by Mitsubishi Heavy Industries. Subject model has proven to be very reliable and efficient - it far excels any of the predecessors. Subject turbocharger is designed to be compatible with all two-cycle and four-cycle engines of Mitsubishi HI.
The content of this video will be of great practical use and interest to the people involved in the maintenance and repair of subject machinery piece during their work on board. The instructions are very clear.
Though the video is quote old, note that it is not outdated and provides engineers with all necessary information. By following the steps described in this video, you will be able to perform the periodic technical maintenance and overhaul of the turbochargers in a very effective and safe way’ this would eventually contribute to the overall safety and efficiency of all machinery on board your ship.
Now, let us see how the Mitsubishi MET-SC turbocharger is opened up and disassembled. To begin with, let us look at the step by step process of the MET-SC turbocharge being disassembled. This starts with the removal of the silencer…
We recommend that you have a close look into this mini-collection of training videos. The set consists of twelve video lessons each covering one aspect of marine engineering. Together they will provide you with the information about engine type designation and engine safety, start and stop routines of diesel engines, engine safety and governing systems, fuel oil system and jacket cooling water system, main and rocker arm lubricating oil systems, control air system, exhaust system and engine air starting system.
The main objective of this training set is to make the operational personnel duly acquainted with the important aspects of operating and maintenance of the machinery they deal with when performing their routing assignments. The material is presented in a form of animations with the text and images and this makes the learning process go much smoother and facilitates easier understanding of the subject by the trainees.
That is why these videos can be used on board for training crew members as well as ashore and even for self-training. All explanations are very clear and the supplementary materials are informative making it easy to follow even to the novices in the world of marine engineering.
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.
An excellent training course from one of the leading classification societies. The training set consists of the booklet accompanied by the two videos.
