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 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.

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.

The FlexCam Technology developed by the MAK specialists and explained in this training video has allowed the marine engineering industry to achieve the real synergy between two systems, namely the advanced air systems and flexible fuel systems commonly providing maximum utilization of the current marine diesel engine design; it also allows to reduce the emission of the smoke polluting the atmosphere and also to improve both load pickup and acceleration.

One of the applications of the subject newly introduced technology is the cruise vessels, where these engines do guarantee virtually invisible smoke coming from them when operated at any loads; in the meantime, the NOx emissions are maintained strictly within the limits set by the relevant current regulations. A really interesting technology which every marine engineer would better be aware of.

We are all aware of the fact that absolutely all hydrocarbons including both oil products and crude oil are normally considered flammable. The IGS, standing for the inert gas systems, are installed on board ships with the purpose of preventing of the potential fires and explosions from happening. That is why they are treated as the critically important arrangements providing safety of the ship and her crew members.

The present training video will demonstrate and explain the main operating principles of the IGS. Taking into account the importance of the properly working and duly maintained inert gas system and the role it plays in the provision of the safe operation of the vessel, it is obvious that any crew member engaged in operation or maintenance of these systems shall have an absolutely clear understanding of its working principles and main components.

We would therefore recommend all such persons to pay serious attention to the content of this video and watch it very carefully. The video is interesting and easy to follow even for the newcomers on board.

This officially released video file describes the Alfa Laval PureBallast which is the ballast water treatment system developed by the company and based on the unique pure ballast concept. Subject system has been already type approved by the IMO and USCG and well met by the maritime industry.

It is energy efficient and offers a truly superior technical performance in fresh, marine and brackish waters. Note that this is the ideal option to choose for the low-clarity water.

Watch this video and get the necessary information which is now quite important taking into account the latest movements regarding the Ballast Water Management Convention entering into force...

This is a training video showing in detail the maintenance of the Sauer air compressors. The three-stage air cooled high-pressure compressors are manufactured by one of the most respected and recognized manufacturers in the world. These compressors are internationally known and used worldwide because of their reliability and effectiveness.

The list of areas where the Sauer compressors are commonly used include commercial shipping, oil and gas industry. naval marine industry and others. Three basic features of the compressors are less temperature and less installation and further maintenance cost. The present instructional video will be helpful to the crew members and shore support personnel engaged in the maintenance of the subject compressors on regular or even occasional basis.

Note that this training should also be useful to the students who can use this video as a visual supplement to their theoretical learning since it covers the most important stages of the maintenance process in detail allowing for proper understanding. we would even recommend this one to the general audience willing to have an idea of how the air compressors are usually maintained and what techniques shall be followed.

We offer you to have a look at this short but still very useful training video film which is intended to provide the description of the basic principles of the shell-and-tube heat exchangers. In fact, this is the interesting and informative animation allowing to observe the whole process of exchanging heat starting from the point where sea water commonly enters the heat exchanger.

It will definitely be of real practical interest for the students of marine engineering and any persons dealing with the day to day operation, periodic routine maintenance or even repair of the subject machinery piece on board ships. Even though the duration of the video is not more than a minute, this is still an excellent way to spend a minute of your time improving your technical understanding of the fundamental operating principles of subject piece of shipboard machinery. We recommend you to have a close look and download this short animation to make it readily available for demonstration to other interested persons.
