Marine Engineering

This is the instructional video produced by the specialists of the B&W company in order to provide required assistance to the crew members performing the periodical overhaul of the exhaust valves. Though most of the information can be found there in the technical manuals to be referred to, some visual guidance will of course be very useful.

Note that there are some other instructional videos available at our website, such as the ones devoted to the overhaul of piston, overhaul of the fuel valves and overhauling the stuffing box of the marine diesel engines and we definitely recommend to download them all as a set readily available when required.

This instructional video film has been prepared and officially released by B&W company, one of the world leaders in the field of construction of the best class marine diesel engines. It is covering all K and L engines produced by B&W and is intended to demonstrate and explain in detail the process of the chain control and adjustment performed on the above stated engines.

Needless to say that the film will be of great practical use for the crew members and shore-based personnel directly engaged in the periodic maintenance and technical overhauls of the shipboard engines as well as to the repair teams. However, taking into account that the instructions presented are very clear and easy-to-follow, this film may be recommended even to the students willing to supplement their paper training materials with the visual instructions.

And here is the instructional video film devoted to the overhauling of the stuffing box of the marine diesel engines - it has also been produced by B&W specialists, the authors of the other videos we have for the overhaul of exhaust valve, overhaul of piston and overhaul of the fuel valve.

Though all operations have been presented by the example of the particular B&W engines, the main principles is obviously same for the majority of the marine diesel engines commonly installed on board vessels.

We would highly recommend to download not only this video but also the others available above, to ensure that the people directly engaged in conducting subject overhauls have some visual and informative aid to supplement the instructions contained in the technical manuals as having some demonstration of the operations will allow for better understanding and eventually better performance of the job.

This is another instructional video prepared by the B&W specialists and officially released by the company. The content of the video shall be thoroughly watched and clearly understood by all people involved in the subject operations.

The video was prepared by the recognized experts in the field so can be recommended not only to the industry professionals but even to the students willing to supplement their theoretical knowledge of the subject with visually available and perfectly explained training material.

Note that the duration is less than ten minutes; however, due to the concentrated approach this was enough for the authors of the film to explain the topic in detail.

The short training video showing the Rolls Royce Promas propulsion and maneuvering system in detail. Subject system is a really novel design integrating the ship's rudder and propeller into a single system in order to provide optimization of the hydrodynamic efficiency.

This design implies fitting a special hubcap on the ship's propeller; subject hubcap is intended to streamline the flow onto a special bulb which is added to the ship's rudder - as a result, the flow separation is effectively reduced after the propeller. Eventually, the propeller's thrust increases since the energy which used to get wasted in the past, is now recovered from the water flow.

The bulb fitted onto the ship's rudder is also adding to the streamlining of the flow reducing the drag. The twisted design of the rudder is providing some further improvement in maneuverability and efficiency. Note that you will gain about 3-8% and 2-6% of additional efficiency for single- and double-screw vessels respectively.

In fact, any ship fitted with such system will benefit. It is much easier to watch this five-minute video and get even better understanding of the advantages that are offered to you by the Promas system.

Here is a very short video animation briefly demonstrating the functioning of the sea water lubricated propeller shaft bearings by Thordon. Subject COMPAC bearings feature long and very predictable wear life and fifteen years of guaranteed service.

They have already proven effective in many commercial vessels - more than six hundred vessels today have Thordon sea-water lubricated bearings installed within their propeller shaft arrangements.

The vessel crew will not have to care about the leakage of oil from the bearings in case they get damaged since there is no oil used in them, and that is why there is no risk of environmental pollution.

They are also featuring much lower operating costs and offer many other advantages that will be appreciated by the ship owners...

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…

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 content of this set of two lessons covers the turbochargers produced by this company. 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.
