The design and construction of light hulls and floats suitable for flying boats and seaplanes is a very highly specialised branch of shipbuilding. This being the case, all matters pertaining to same Should be in the hands of naval architects. At a recent lecture before this Society, Commander Hunsaker, of the United States Navy, stated that British aircraft designers followed the naval architect's methods more than in any other country; he thought this was natural as he gave us the credit of being the first maritime power of the world. This may be perfectly true with regard to airships, but I cannot endorse his opinion that the majority of flying boats built in this country show the impress of the trained hand of a naval architect. I do not imply that the American boats are superior to ours, as for instance, a large American boat with twin engines built in the United States, which we used for the North Sea patrol, was by no means typical of good boat-building ; there were no less than four consecutive planks butted—not even scarfed—on the same timber, which had a siding of 5/8in., the line of butts being in line with the step where the boat was naturally weakest.

Offshore hydrocarbon resources have been developed for many decades, and with technology improvements, many fields which were once impossible to develop, are now economically and technologically feasible. This has led to a growing difficulty in determining the legislative and regulatory framework for resources that straddle the recognized borders between two states. In this paper, we examine a successful framework agreement governing the transboundary resources between the United Kingdom (“U.K.”) and Norway in the North Sea, and the agreement between the United States and Mexico governing the Gulf of Mexico. Following the 2013 Energy Reform, the Mexican energy sector has been revitalized, leading to greater exploration, development, and production than ever before. This means that in the near future transboundary resources may be licensed for production, bringing the issues highlighted in this paper to the attention of multiple government and international entities. This paper seeks to recommend improvements to the transboundary framework in the Gulf of Mexico based on the successful framework agreement utilized in the North Sea. This paper begins by introducing international law for offshore resources in Part II. Part III discusses the offshore regulatory regimes in the U.K. and Norway, analyzing how the two states have successfully used bilateral agreements to facilitate cooperation regarding effective exploitation and apportionment of costs from cross-boundary offshore oil and gas projects in the North Sea. Part IV discusses the offshore regulatory regimes in the United States and Mexico and analyzes the current transboundary agreement in place for the Gulf of Mexico. Part V compares the transboundary agreement governing the North Sea and the same governing the Gulf of Mexico. We highlight the major differences in the agreements and suggest changes to the Gulf of Mexico agreement based on the successful North Sea agreement. Finally, this paper concludes and provides key policy recommendations to improve the rules and regulations surrounding the exploitation of transboundary hydrocarbons in the Gulf of Mexico.

The French jurist, Méderic Louis Élie Moreau de Saint-Méry (1750-1819), was driven into exile during the French Revolution by Robespierre's accession to power. From 1794 to 1798 Moreau lived in the United States. In the journal he kept during these years, he described American young girls as follows: American girls are pretty, and their eyes are alive with expression; but their complexions are wan, bad teeth spoil the appearance of their mouths, and there is also something disagreeable about the length of their legs. In general, however, they are of good height, are graceful, and, in enumerating their charms, one must not forget the shapeliness of their breasts. Philadelphia has thousands of beauties between fourteen and eighteen. To offer but a single proof: on the north side of Market Street, between Third and Fifth Street, on a single winter's day I saw four hundred young maidens promenading, each one of whom would surely have been followed in Paris, a seductive tribute that could be offered by perhaps no other city in the world. But these girls soon became pale, and an indisposition which is reckoned among the most unfavorable for the maintenance of the freshness of youth is very common among them. They have thin hair and bad teeth, and are given to nervous illnesses. The elements which embellish beauty, or rather which compose and order it, are not often bestowed by the graces. Finally, they are charming, adorable at fifteen, dried up at twenty-three, old at thirty-five, decrepit at forty or fifty.

The American poet Robert Frost famously mused on whether the world will end in fire or in ice. Nuclear weapons can deliver both. The fire is obvious: modern hydrogen bombs duplicate on the surface of the earth the enormous thermonuclear energies of the Sun, with catastrophic consequences. But it might be a nuclear cold that kills the planet. A nuclear war with as few as 100 hundred weapons exploded in urban cores could blanket the Earth in smoke, ushering in a years-long nuclear winter, with global droughts and massive crop failures. The nuclear age is now entering its seventh decade. For most of these years, citizens and officials lived with the constant fear that long-range bombers and ballistic missiles would bring instant, total destruction to the United States, the Soviet Union, many other nations, and, perhaps, the entire planet. Fifty years ago, Nevil Shute’s best-selling novel, On the Beach, portrayed the terror of survivors as they awaited the radioactive clouds drifting to Australia from a northern hemisphere nuclear war. There were then some 7000 nuclear weapons in the world, with the United States outnumbering the Soviet Union 10 to 1. By the 1980s, the nuclear danger had grown to grotesque proportions. When Jonathan Schell’s chilling book, The Fate of the Earth, was published in 1982, there were then almost 60,000 nuclear weapons stockpiled with a destructive force equal to roughly 20,000 megatons (20 billion tons) of TNT, or over 1 million times the power of the Hiroshima bomb. President Ronald Reagan’s ‘Star Wars’ anti-missile system was supposed to defeat a first-wave attack of some 5000 Soviet SS-18 and SS-19 missile warheads streaking over the North Pole. ‘These bombs’, Schell wrote, ‘were built as “weapons” for “war”, but their significance greatly transcends war and all its causes and outcomes. They grew out of history, yet they threaten to end history. They were made by men, yet they threaten to annihilate man’.

Supply chain management is the relatively recently implemented concept of managing an integrated supply function from production of a product or service to its receipt by its ultimate end user.This management philosophy has revolutionised production and manufacturing industries throughout the world, and has brought about dramatic efficiency improvements, with similar effects upon reducing overall costs. Traditionally, this was an area that was considered of low priority, presenting little opportunity for value adding or innovation, and characterised by adversarial, uncompetitive management techniques.Similarly, in the oil and gas industry, especially in the North Sea and the Gulf of Mexico, extended supply chains have necessitated a re-evaluation of the mechanisms used not only for provision of the supply service, but in the relationship between the operator and the service provider. Most notable examples being the CRINE (Cost Reduction Initiative for the New Era) initiative in the United Kingdom and Chevron Corporation's (one of West Australian Petroleum's participants and also its technical advisor) CSQIP (Chevron Supplier Quality Improvement Process) methodology.This paper will concern itself therefore with the application of cutting edge Supply Chain Management techniques garnered from both the North Sea and the United States. Focussing specifically upon alliancing/partnering, resource sharing and outsourcing, upon West Australian Petroleum Pty Limited (WAPET) and its respective contractors.It will seek to show that through innovative use of current supply chain management tools, as well as imaginative 'out of the box' thinking by WAPET personnel and contractor personnel alike, significant cost reductions and performance improvements can be brought to bear on oilfield operating costs.

This paper, prepared by the Hydrographic Office of the United States Navy Department, and based on recent American experience, was originally printed on the back of the April 1958 Pilot Chart of the North Atlantic Ocean. It is reproduced here by kind permission of the Hydrographer of the United States Navy. A less extensive treatment of the subject, to which readers may like to refer, was given by L. R. R. Foster in the Journal in 1952 (‘Some Recent Work on Polar Navigation’, 5, 12). Figs. 1–12 are reproduced from the Polar Record (8, 1956–7) by kind permission of the Scott Polar Research Institute, Cambridge.The first requisite of the embryonic ice pilot is to develop a healthy respect for the tremendous power of the ice. He must never permit the peaceful appearance of an ice-field to lull him into a false sense of security. On the other hand, he need not fear the ice, since a great deal of progress through ice can be made by a vessel in capable hands.

Ever since man first ventured to sea, he has needed to know not only where he was in relation to the land but also what dangers lay hidden below the surface, and what courses to steer in order to avoid these unseen dangers so as to arrive safely and speedily at his destination – making due allowances for the effects of tidal streams and currents.Because his sea-maps were working documents, usually exposed to a hostile environment, fewer such old records have survived than is the case with old land maps. Undoubtedly, whilst many early voyages of exploration emanated from Europe, it should not be forgotten that in the – to European eyes – ‘unexplored’ parts of Asia and the Pacific, similar voyages were being made. However, as trade developed between Europe and the rest of the world, hydrographic surveyors from Europe began to record the information needed along the various trade routes.

The command crisis as a story line has been used in many references of the cinema war genre throughout years, but it is in the stories framed under the surface of the sea where it can reach its greatest destabilization capacity. The films of the subgenre suggested to exemplify this study are the North American Run Silent Run Deep (Robert Wise, 1958) and Crimson Tide (Tony Scott, 1995). Both films were produced during a post-war era and narrate the rivalry of a commander and his executive officer in wartime submarines of the United States Navy. Commanding problems severely affect the ecosystem of the ships, creating a struggle for control during patrol. By means of observation, the relationship between History and these films will be analysed, as much as the strategy and narrative process with the objective of verifying keys in the use of the plot.

AbstractApproximately 175,000 mines were laid in the Baltic Sea during the world wars, and in former mined areas in general, 10‐30% of the mines remain sunken on the seabed. The search for a Swedish aircraft downed in 1952 led to the finding of previously unknown minefields in the Baltic Sea. Subsequent historic research has identified approximately 1,985 minefields in the Baltic Sea and 4,400 minefields in the North Sea. These historic minefields present an impediment to the use of the Baltic and North Seas and are a real danger to the increasing shipping, fishery, and exploration of the seabed. The Baltic Ordnance Safety Board (BOSB) was established in 2006 to assemble information on mines and other explosives in the Baltic Sea, to prioritize areas for mine clearance, and to coordinate multinational mine clearance efforts across the Baltic Sea. The BOSB has improved the efficiency of mine clearance and the safety of seafarers and all those who have the seabed as their working ground.
