One more instructional video from B&W specialists - the present film is devoted to the process of adjustment of the mechanical VIT-system. The VIT, standing for the variable injection timing, is a function of the diesel engine associated with the load-dependent adjustment of pressure developed in the combustion chamber and allowing to get to the maximum pressure during the part load helping to decrease the consumption of the fuel oil and also to reach to the efficient combustion.

The content of this training video will be of practical use to the personnel engaged in the operation and maintenance of the marine diesel engines with the VIT, and facing necessity to perform the associated adjustment. The explanation provided is very clear and will be understandable even to the people without too extensive experience with subject marine engines, who would like to use this video as a reference and supplementary training material. As it is the case with any other training videos from B&W, this one is remarkably informative and interesting, and will be appreciated by any engineer and student.

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.

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.

One of the best training packs for the persons willing to get a full understanding of the electrical installations onboard marine vessels, their arrangement and operations, from the very basic knowledge to the in-depth analysis. The pack is made of eight video films each of them covering one particular topic.

The first video is devoted to the maintenance of the shipboard electrical systems and safety issues involved, and this is a sort of intro. The other films deal with the starters and motors, distribution of the electrical energy, survey requirements, ancillary services, main circuit breakers, alternators, special electrical practices etc.

Note that the electric propulsion and high voltage matters have been addressed in two films due to the large size. There is a separate pdf file providing some supplementary information on shipboard main and auxiliary electrical systems, high voltage safety, certification and classification requirements, and other important issues.

Recommended for the students and crew members engaged in the operation, maintenance and repair of the electrical equipment and systems on board - they will find absolutely all information in a single video course and may wish to supplement it with the book on practical marine electrical knowledge we have.

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.
