Obviously, the most serious test of the buoyage systems occur once the mariners have been  directly confronted by the light marking some uncharted danger, for example a recent ship wreck, and particularly it this happens at night or in the conditions of low visibility. That is exactly the time when mariners must make the immediately, correct and positive decisions.

The very beginnings of the uniform buoyage system emerged more than a century ago when some of the countries did agree on marking of the port side of shipping channels with the can buoys of black color; the starboard hands, in turn, were marked with the conical buoys of red color. However, this caused some discrepancy between the ways of using and marking the buoys in Europe and North America. There have been several conferences held on this matter to work out a single buoyage system, however without any significant success until 1936 when one of the proposed systems was agreed.

Again, some of the countries did not become signatory to the convention and developed their own, original and opposite buoyage systems. Long story short, all efforts have finally resulted in the establishment of the IALA system and its wide implementation all over the world. Note that in some parts of the planet the conversion to the IALA systems has not been completed yet...

The interested readers have already found this volume remarkably informative and enjoyable. The content is reflecting the "British" point of view on the story, containing so many relevant historical facts and details. Numerous excellent maps are supplementing the text descriptions, allowing readers to better understand what happened. According to the feedbacks, this volume is exactly what the intelligent readers would expect. such endeavor.

Talking about the battle itself, the people will always award the overall victory according to their personal judgment. The book should be highly recommended to the people with the interest in naval history and naval warfare of the past centuries, even regardless of the background. Even the general readers will definitely find the content of this title fascinating, appreciating the historical information, images and maps.

Charles London has made the professional selective use of the technical information and data available on the famous naval battle, noting that the gunnery possessed by the both sides was nearly same and also noting the fact that technical advantages and defects of the designs of the ships participating in the battle from both sides actually did cancel each other out. Numerous beautiful illustrations by Howard Gerrard are the excellent supplement to the text content.

This nice and informative historical account is dedicated to not too glorious days in the history of the Royal British Navy fleet. The content of this book by "Tank" Nash is describing the whole chain of the historical disasters which in fact were avoidable - it all took place in the January of 1918 when the elements of the Grand Fleet were conducting a transit to the place where the naval exercises were planned to be conducted in the North Sea.

The content of the publication was made up on the basis of the invaluable contributions by the professional scientists and researchers, and is drawing a really great deal from the ADM 156-86 Admiralty file. The author of this historical book is a soldier who wanted to be a sailor for all his life.

As the name of the title implies, it will tell readers a very interesting and true story of what happened during the famous Battle of the Isle of May; the text of the book is arranged in seven major sections and supplemented with the numerous informative illustrations, and such approach lets the readers build the full and clear picture. The author was inspired to write this work as he could see the Isle of May itself and the "battlefield" from his residence in North Berwick...

This instruction book describes the installation of the propulsion turbine unit and provides the standard concerning the operation, maintenance, overhaul and inspection. But this instruction book does not purport to cover all details in equipment nor to provide for all possible troubles to be encountered in connection with installation, operation or maintenance.

If further information should be desired or particular problems should arise which are not covered sufficiently for the owner's purpose, the matter should be referred to Kawasaki Heavy Industries, Ltd., Kobe, Japan. Contents - General description of the main propelling machinery; Construction; Operation and maintenance; Figures.

The kite propulsion has already emerged as one of the promising and attractive ways of harnessing the power of the wind to yield the financial and also environmental benefits. In order to better facilitate both design and optimization of the propulsion systems of this type, people have to possess a thorough understanding of the dynamics affecting the kite motion and all resulting forces.

The present thesis contains the results obtained from two line tension models and those results have been compared with the time histories for the flights collected during the experiments. Some new methodologies for the investigation of kite performance have been established. The first model is the "zero mass model" assuming that both kite and lines have no weight, while the second model - "lumped mass model" considers the mass of the kite and therefore makes use of the motion equation.

It has been determined that both models converge to same results in the limit where the mass of the kite is tending to zero. The publication covers such important topics related to the kite propulsion as experimental methods to record the trajectories of the flights, comparison of the models mentioned above, determination of the kite forces using 3D flight trajectories, fuel saving issues etc.

The Kongsberg Simrad GreenDP® (SDP) system is a computerized DP control system enabling automatic heading/position controls of a vessel. The system operator specifies the setpoints for position/heading; then, they shall be processed by the SDP system to provide thrust control signals to the ship's thruster plus main propeller systems.

The propulsion units which are currently in use are allocated optimum thrust by the system. The SDP system uses the information obtained from the gyrocompasses in order to control the ship's heading, and minimum one PRS, i.e. position reference system, lets the system control the position.
