The present software developed by Shell Company is a very handy electronic shell marine products catalogue; it consists of six major parts dedicated to start fuel specification and lubricants, safety data sheets, lubricants, contact, product data sheets, and Shell BunkerCalc program. It will be of some use for people dealing with purchase of marine products. Good mostly for training purposes.

However, can also be used for better familiarization with the nomenclature of the fuel oils and lubricants that are in use in marine industry. Apart from the software, the pack of files presented to your attention, includes numerous files providing information on the properties of various fuel oils, such as blended and distillate MDF.

The other files provide advice on storage and handling of the lubricants, siting the store, stacking barrels, bulk storage etc. Specifications for various marine fuel oils produced by Shell are also there, together with the table comparing those fuels to British and ISO 8217 standards. In addition, the pack includes a very good fuel specification guide to all Shell marine products, and safety data sheets for all lubricating oil and fuel oil products.

Here is a very popular book about sharks. Nowadays, their attacks are natural news leaders. The sharks are the perfect showstopping spectacle: horror, blood and guts, and mystery. In addition to that, they are highly videogenic. Even in the case when the camera cannot get a proper shot of shark or its victim, it can still pan the empty beach, the forbidding ocean, focus on the warning signs like "Danger: Sharks" or "Beach Closed".

Such attacks usually dominate the news in the summertime. Magazines, newspapers, magazines, TV and radio news, internet websites keep count of the numerous incidents of supposed carnage. Experts speculate on the meanings and causes of this assault on humanity. The truth is that such hysteria is not justified by statistics or other facts. Though shark attacks seemed to occur more frequently as the twentieth century went on, they leveled off during the 1990s. 60-80 attacks are reported all over the world each year.

The present official supplementary reference document was specifically prepared and officially released by the  specialists of the world respected Electro Static Technology ITW and is primarily dedicated to the VFD, standing for the variable frequency drives. When the PWM VFD, i.e. pulse width modulation drives were developed using IGBTs, i.e. the insulated gate bipolar transistors, this advanced and newly presented technology was first applied to controlling electric induction motors in both commercial and industrial applications.

The advantages were obvious: Torque and motor speed could now be precisely controlled to optimize both process and energy requirements, The potential to save energy by operating motors at only the required speed and, at the same time, maintaining applicable torque requirements would potentially result in a 20% to 50% energy savings, Processes can be optimized and controlled by computer processing systems to achieve productivity increases or energy savings.

Nowadays, the use of these variable frequency drives is slowly getting increasingly common when making attempts to save the energy in HVAC systems and to reduce the associated energy costs. When using the VFD technology, please note as necessary that this type of motors shall always have the bearing protection in order to ensure reliability and safe operation.

SFOC is standing for the Specific Fuel Oil Consumption. The associated methods of optimization are covered within this publication released by MAN B&W for their two-stroke IMO Tier II diesel engines. Here is the contents: Introduction; Influence of Nitrogen Oxide Regulations on reduced Specific Fuel Oil Consumption; Engine Turning Methods (Available Exhaust Gas Bypass, Variable Turbine Area and/or Turbine Geometry, Engine Control Tuning); Potential Fuel Savings on Low-Load Operation; Summary. One of the main objectives in the maritime industry of today is the reduction of the impact the carbon dioxide release has to the atmosphere...

Crossing an ocean under sail today is not an especially risky undertaking. Accurate offshore navigation—for so long an impossible dream—has now been reduced to the press of a button, and most modern yachts are strong enough to survive all but the most extreme weather. Even if errors, accidents, or hurricanes should put a boat in danger, radio communications give the crew a good chance of being rescued.

Few sailors now lose their lives on the open ocean: crowded inshore waters where the risk of collision is high are far more hazardous. But it was not always so. When a young man called Alvaro de Mendana set sail from Peru in November 1567 to cross the Pacific with two small ships, accompanied by 150 sailors and soldiers and four Franciscan friars, he faced difficulties so great that his chances of survival, let alone achieving his objectives, were slim. Mendana's orders from his uncle, the Spanish viceroy, were to convert any "infidels" he encountered to Christianity, but the expedition was certainly not motivated entirely by religious zeal.

According to Inca legend, great riches lay on islands somewhere to the west. Were these islands perhaps outliers of the great southern continent that was believed to lie hidden somewhere in the unexplored South Seas? Mendana, who was twenty-five, hoped to find the answer, to set up a new Spanish colony, to make his fortune and win glory. However, any optimism he may have felt as the coast of Peru dipped below the horizon would have been misplaced.

Although Magellan had managed to cross the Pacific from east to west in 1520-21, he had been killed in fighting with local people after reaching the Philippines, and only four out of the forty-four men who sailed with him aboard his small flagship had returned safely to Spain. This first epic circumnavigation was counted as a brilliant success, but other expeditions ended in oblivion.

The present book begins with the very brief intro to the basics of the semiconductor technology, including their structure, band theory of crystals and description of the energy level diagram. Difference between extrinsic and intrinsic semiconductors is explained in this opening chapter, and types (N- and P-) of the extrinsic ones have also been covered together with some other information.

The next chapter has been dedicated to the semiconductor junction diodes while the third one addresses the diode circuits and provides the necessary information about clippers, clampers, rectifiers, comparators, filter circuits, voltage multiplying circuits etc. Then there comes a chapters dealing with the transistors, integrated circuits, and their fabrications.

The rest of the titles include transistor biaising techniques, two-port network theory and circuit models, small signal basic amplifiers, multistage and feedback amplifiers, power, tuned and wideband amplifiers, oscillators, multi-vibrators, basic logic gates, and other information. Definitely needful publication for the electricians and all people dealing with the design, maintenance and repair of the electrical equipment and systems.

This remarkable work by Michael Connolly is tracing the rise of the American-Irish community of immigrants in Portland, Maine looking at its control of the waterfront labour over nearly a century. The present publication shall be treated as invaluable contribution to the local labour history situating its subject within much broader picture of American history at the crucial times during the formation of the social and economic identity of the nation.

The author has vivdly revealed how the maritime culture of America has declined over quite a short period of time. The author has provided the crucial professional insight into the ethnic dimension of the longshoremen of New England. He has offered his readers a truly in-depth scientific study of the on-shore labour forces making the port function for a century...

Here are some topics covered within this pack containing the most important proceedings and technical papers of the second ISSW held in Osaka, Japan some years ago with the best experts participating. The first session of the document is dedicated to the surf-riding, broaching as well as capsizing of the ships in following and quartering seas, providing some remarks on such phenomenon as broaching, and addressing various geometrical aspects.

The second session deals solely with capsizing of the vessel in following and quartering seas, including research of the parametric resonance of the vessel in astern seas and results of the studies on the transverse ship stability of a HSC (high speed craft).  The third session covers the capsizing of the ship in beam seas, including non-linear roll motion of a vessel with water-on-deck in irregular waves.

The three remaining sessions of the document are all related to the damage stability of the vessel and address capsize model experiments with a damaged vessel model, new probabilistic approaches to the stability of the damaged ship and assessment of the survivability, and ship capsize dynamics under condition of the flooded internal spaces including shifting of cargo.
