Nautikerns möjlighet att reducera bunkerförbrukningen

Branelius, Oscar, Albertsson, Richard January 2009 (has links)
<p>The work aims to clarify what nautical officers onboard in today's merchant can do to help reduce bunker consumption during the voyage? The question we have asked ourselves during the autumn term in 2008 much was said about the premium bunker prices, and how the future could affect our daily lives as nautical officer. We felt here that the school had relatively little knowledge of the subject and therefore felt that it would be interesting to identify how it really looks like onboard the ships today. To collect information we contacted 7 Swedish companies that operate with different types of vessels, in order to get a broad picture of the whole industry. For shipping companies we asked questions about how actively they were working on the issue and what methods they used. We found that the owners worked with the issue but that it so far was a little on the go. All but one company in the survey provided the vessels are instructed to run bunker efficiently.</p> / <p>Arbetet syftar till att klarlägga vad nautikerna ombord i dagens handelsfartyg kan göra för att reducera bunkerförbrukningen under pågående sjöresa?

The Mica shipwreck: deepwater nautical archaeology in the Gulf of Mexico

Jones, Toby Nephi 30 September 2004 (has links)
The purpose of this study was to describe the investigation of the Mica shipwreck. The objectives of the investigation, as identified by nautical archaeologists from the United States Minerals Management Service and the Nautical Archaeology Program at Texas A&M University, include determining the extent and limits of the wreck site, acquisition of diagnostic artifacts to identify the temporal period of the shipwreck and its mission at the time of loss, to identify the type of ship and its country of origin, and quantify the relationship between the vessel's construction and function. The manuscript contains a thorough analysis of the equipment and approach used by archaeologists during the excavation. The manuscript also briefly explores the use of metallic ship sheathing during the eighteenth and nineteenth centuries, focusing specifically on the pure copper sheathing found on the Mica wreck. Sheathing from numerous contemporary vessels will be analyzed and compared to the Mica shipwreck sheathing.

The history and development of caravels

Schwarz, George Robert 15 May 2009 (has links)
An array of ship types was used during the European Age of Expansion (early 15th to early 17th centuries), but one vessel in particular emerges from the historical records as a harbinger of discovery: the caravel. The problem is that little is known about these popular ships of discovery, despite the fair amount of historical evidence that has been uncovered. How big were they? How many men did it take to operate such a vessel? What kind of sailing characteristics did they have? How and by whom were they designed? Where did they originate and how did they develop? These questions cannot be answered by looking at the historical accounts alone. For this reason, scholars must take another approach for learning about caravels by examining additional sources, namely ancient shipbuilding treatises, archaeological evidence, surviving archaic shipbuilding techniques, and iconographic representations from the past. Information gained from the available sources reveals many of the caravel’s characteristics through time. This ship type outclassed its contemporaries during the age of exploration because of its highly adaptive characteristics. These traits were, principally, its shallow draught, speed, maneuverability, and ability to sail close to the wind. This combination of attributes made the caravel the ideal ship for reconnaissance along the rocky African coastline, as well as for making the transatlantic voyages to the New World. It was built in a Mediterranean way during its post-medieval phases, a method that still survives in some parts of the world today. During the Age of Discovery (ca. 1430 to 1530), the caravel sat low in the water, had one sterncastle, and was either lateen-rigged or had a combination of square and lateen sails. This vessel reflects the advanced shipbuilding technology that existed in Europe at this time, and played and important role in the voyages which allowed the Europeans to expand their territories around the world. The results of the studies presented in this thesis provide a history and development of the caravel, which was gradual and often obscure. What has been gained from this work is a body of information that can be applied to other studies about ancient seafaring, and can serve as a starting point for further research.

Nautisk turism : en jämförelse mellan svenska och kroatiska förhållanden / Nautical tourism : a comparison between the condition in Croatia and Sweden

Wenck, Josefine, Haag, Sara January 2009 (has links)
<p><strong>Abstract</strong></p><p>A tourism genre that has developed in recent years is the nautical tourism, nautical tourism is described as a tourism genre that includes all activities in relation to water. Croatia is one country that has invested in and has good presumption for this type of tourism, and has also received an international recognition as a top destination within the nautical tourism genre. The purpose with this thesis is to increase knowledge about the nautical tourism development in Croatia, and to see if it would be possible to develop on Swedish conditions. Sweden is a destination with a large number of archipelagos, located in both inland lakes and along coastal areas. Stockholm archipelago is one of the world's largest archipelagos which has a long tradition as a tourist destination. Literature studies and a number of interviews with actors in the Croatian and the Swedish tourism industry have been made to enable this thesis. Based on this study, we have seen an increase of nautical activities in Croatia which has had positive impact on the country´s tourism industry and their citizen. When it comes to Sweden the study has shown that development of nautical tourism is possible, but in a smaller volume than in Croatia. Partly because of the short summer season and the image that is created around Stockholm archipelago.</p>

His Majesty's hired transport schooner Nancy

Sabick, Christopher Robert 29 August 2005 (has links)
In 1997 a group of archaeologists from Texas A&M University's Nautical Archaeology Program traveled to Wasaga Beach, Ontario to document the hull remains of the eighteenth-century schooner Nancy. In 1927, the schooner was recovered from the banks of an island in the Nottawasaga River, near its confluence with Lake Huron. The hull is now on display in the Nancy Island Historic Site. Despite being available to the public for more than 75 years, the 1997 documentation was the first to thoroughly record the construction of the vessel. In addition to archaeological investigation, historical research was carried out to further our understanding of Nancy's commercial and naval career. The archaeological data reveal a schooner that was built by talented shipwrights using the fine timber harvested around the Great Lakes in the eighteenth-century. This study adds a considerable amount of new information to the otherwise scanty base of knowledge available on the construction of early Great Lakes sailing vessels. Historical research shows that Nancy and her crews were participants in many important events that shaped the Great Lakes Region. From her construction in Detroit in 1789, Nancy was employed in the fur trade. As tensions flared between Great Britain and the United States in 1812, Nancy was utilized as an armed transport for the British forces around the lakes. in August of 1814, the schooner was trapped in the Nottawasaga River by a strong American naval force. Nancy's commander set fire to the vessel to deny it to the enemy. This thesis examines the construction details and history of the schooner Nancy in detail. Preliminary chapters will provide the historical context for the vessel and describe Nancy's long journey that ended at the Nancy Island Historic Site. The second half of the thesis describes the construction of the schooner and compares it with other contemporary vessels. The study concludes that Nancy's hull represents an eighteeth-century construction tradition modified for use on the Great Lakes, and also demonstrates the vessel's dual roles as trader and military transport.

The Rincon Astrolabe Shipwreck

Garcia Ortiz, Gustavo Adolfo 12 April 2006 (has links)
On 30 December 1986, a local fisherman incidentally discovered the remains of a seventeenth-century merchantman off the coast of Rincon, a small municipality on Puerto Rico's west coast. Some days later, he and some acquaintances extracted objects from the site and stored them in a nearby restaurant. The assemblage of artifacts recovered included, among other items, pins, scissors, ordnance, pewter ware, woodworking tools, a myriad of concretions and a nautical astrolabe. It is from the last that the wreck site took its name. The operation continued for months until local authorities, alerted by a member of the salvage group, issued a cease and desist order. At that point, the whole affair entered a legal process that on the summer of 2005 had not reached its conclusion. The purpose of this thesis is twofold. First, the author presents the story of the shipwreck from the moment it was found until the court ruled regarding ownership of the artifacts. Since this was the first time ownership of a shipwreck was debated in Puerto Rican courts in recent history, this gives the reader an idea of how legal precedence was established concerning the island's submerged cultural resources. Second, based on what was popularly perceived to be the site's most remarkable find, a study was developed on the sea or mariner's astrolabe, a navigation instrument that played a fundamental role in the process of European maritime expansion during the late fifteenth, sixteenth and seventeenth centuries. The reader of this text will learn that, during the fifteenth century, Portuguese navigators saw the need to gradually depart from the traditional Mediterranean navigation technique known as "dead reckoning." As their explorations along the West African coast forced them to sail far into the Atlantic Ocean for prolonged periods, a new method was developed that consisted of measuring the angle of certain heavenly bodies above the horizon in order to determine the latitude of the observer with reasonable precision. For this purpose, instruments that traditionally belonged to the field of astronomy were adapted to be used by seamen. Among them was the astrolabe, which became the most popular by the turn of the sixteenth century. After discussing the instrument's origin and development, the author analyzes how a renewed interest on the nautical astrolabe, which emerged in Portugal in the early twentieth century, introduced the instrument to the field of modern scholarly research. This work also presents a catalogue of sixteen sea astrolabes, some of which have never been published. The catalogue shows statistics and other relevant information, while placing the artifacts in the context of the previously existing data.

Archaeological evidence for ship eyes: an analysis of their form and function

Nowak, Troy Joseph 17 September 2007 (has links)
During the late 19th century, a number of large marble eyes were discovered near the Athenian naval facilities at Zea. Although initially published as the eyes of ancient Greek warships, many scholars have doubted the validity of this attribution. A range of hypotheses have been presented in attempts both to discredit the notion that they are ship eyes, and to re-classify these objects. Recent excavations of a Classical Period merchantman at TektaŸ Burnu uncovered a pair of marble discs that again raise questions relating to the identity of the marble eyes from Zea. A review of alternative hypotheses relating to the identity of these objects based on textual, archaeological, and representational evidence, coupled with technical analyses of their construction, form, and decoration, leads to the conclusion that the marble eyes discovered at Zea, as well as the objects from TektaŸ Burnu, adorned the bows of ancient Greek ships between the 5th and the 3rd centuries BC. Evidence for the function of these objects is found in the works of Greek authors who show that the eyes of ancient ships marked the presence of a supernatural consciousness that guided the ship and helped to avoid hazards. Studies of eye representations on Archaic and Classical Greek domestic articles and parallels in architectural decoration suggest that ship eyes may have also worked as apotropaions to counter forces such as envy. As early as the 5th century BC Greek and Latin authors attest to a fear and understanding of envy's destructive power, which was believed to attack through the actions of both gods and mortals. Theories related to the use of eyes as apotropaions that could counter envy are presented based on analysis of material from the Archaic and Classical Periods. Links are made between Hellenistic and Roman mariners and their fear of this force, which was expressed in their use of devices that functioned to protect them from its ill effects. It is possible that ship eyes in ancient Greece served as both epiphanies and apotropaions used to counter envy.
