GUIDANCE ON PREPARING CARGO HOLDS AND LOADING OF SOLID BULK CARGOES

The proper preparation of the cargo holds of the vessel for the intended carriage is deservedly considered one of the key elements of the bulk carrier operations. Subject preparation requires very careful and thorough planning followed by the competent execution.

It shall be understood that the lack of due preparation will not only lead to the claims relating to the cargo quality, e.g. its contamination/water ingress or shortage claims, but may also result in the different contractual claims related to the delayed or failed surveys, charter-party disputes and off-hire claims.

The process of preparation of the cargo holds commences well in advance, even before the intended cargo lands on the tank top for the first time and there are numerous factors to be considered in order to ensure that the preparation has been conducted in a correct and efficient manner. Some of the cargoes may require just sweeping out of the cargo hold plus washing, while for the other cargoes such preparation would not be considered sufficient.

It is very important to have a clear understanding of what exactly is required; note that all people on board including crew members and Master shall be aware of all processes involved. To ensure smooth voyage, careful attention shall be paid to the cargo at the time of fixing. ..

GUIDANCE NOTES FOR FIRE LOADINGS AND PROTECTION

Introduction; Abbreviations and terminology; Design conditions and safety systems influencing the fire behaviour; Fire protection principles in design; Establishment of design loads; Fire mitigation measures; Fire response; References. These LR Rules require a FE, i.e. Fire and Explosion Evaluation, report to be submitted.

This report is primarily aimed to serve as the assessment of the potential blast pressures and fire loadings, on the bases of the specific fire hazards that are associated with the unit's general arrangement as well as production and process activities taking place; the operational constraints are also to be taken into account. The present Guidelines should to be treated independently of the formal Quantitative Risk Analysis (QRA); however, the input on ignition probabilities and leak scenarios usually taken from the QRA, are required.

Significant portion of the Guidelines has been dedicated to the basic principles of fire protection, measures for fire mitigation and fire response, that make one of the parts of the FEE and closely relate to any potential fire loadings. The Notes are intended to serve as a live document that may be changed without prior notice.

GERMAN CRUISERS OF WORLD WAR TWO IN ACTION

The cruisers that fought in World War Two descended from sail-powered frigates. These vessels were designed for long-range independent operation to gain information about the movement of an enemy's fleet, to raid an enemy's commerce, or to track down and defeat an enemy's commerce raiders. This led to the famous frigate vs. frigate duels of the American Revolution and the War of 1812, in which the advantage generally went to the Americans.

This was due to the stouter construction and slightly larger guns of their frigates, including USS CONSTITUTION, better known as "Old Ironsides". Generally, a successful cruiser was a ship possessing high endurance and enough speed to outrun anything bigger, enough power to defeat anything its own size. It also had enough protection to survive encounters with any number of smaller units without disabling damage. Meeting this set of requirements with steam-powered metal ships was far more difficult than with wind-powered wooden ships. High-speed from a steam engine can only be achieved at the expense of range. Unlike sail powered ships, whose range was limited only by the amount of food and water carried for its crew, steam-powered warships consumed coal or oil at rates directly related to the ship's speed.

The more armor and armament a ship carried, the more fuel it took to achieve a particular speed. Even at most economical consumption rates, a cruiser-sized ship could never achieve the independence of operation synonymous with the frigates they replaced, without the ability to refuel at regular intervals. This led to the development of networks of coaling stations in all the places a navy might expect to operate and points in between. Colonial expansion before the advent of steam had concentrated on sources of wealth, including the gold of South America and the spices of India and the East Indies. Now parts of the world that had previously been of little interest - including the coast of Africa and Pacific islands - became the objects of intense competition between expansionist colonial powers. This competition led directly to World War One.

GERMAN BATTLESHIPS OF WORLD WAR TWO IN ACTION

The present historical publication is dedicated to the Kriegsmarine, which is the original name of the German Navy. Subject branch of the German Forces was actually the smallest of the three branches of Wehrmacht with which Germany started the war back in 1939, two other branches of the German Armed Forces were the famous Luftwaffe in the air and Heer on land.

At that time, the Americans, Japanese and British armed forces all had much larger and powerful navy fleets, and the German Navy rested in the second rank together with the Italian and French fleets. There were several cultural and historical factors considered the reason for such situation. First of all, the navy fleet of the Imperial Germany constructed before and during the First World War, was truly formidable and forced the British into serious expenditures for maintaining their primacy at sea. After the defeat of Germany in 1918, the Allied forces did not intend to allow Germans to build a navy fleet again as it would one day be able to challenge the Great Britain's command of the sea.

As a result, Germany had been forced to surrender all of the warships and was only left with a rump fleet that consisted of a few old cruisers and battleships... The text part of the book worked out by the naval expert Robert Stern has been supplemented with the excellent and informative illustrations by Darren Glenn.
