Vernacular boats and boatbuilding in Greece

Damianidis, Kostas January 1991 (has links)
This work presents a study of the vernacular boats of modern Greece. A new typology of boats is offered, and an account is given of tools and boatyard practice, design and construction techniques. Evidence for these subjects is drawn from field surveys, museum collections, iconographic studies, and interviews with old boatbuilders. Although most of the information presented comes from the first half of the 20th century, background information from the 18th and 19th centuries is also covered. This longer historical perspective is particularly important in making comparisons between 20th century practices and the boatbuilding techniques of the past. There is evidence for the existence of two main periods of technical change in the industry, namely, the late 18th century, when new methods such as lofting were introduced, and the late 19th century, when changes in the wider shipbuilding industry initiated a process of decline in vernacular boatbuilding. At the same time however, a number of older techniques, for example certain moulding methods, survived at least into the first part of the 20th century. This work offers new insights into the design methods involved in the control of hull-form during "skeletonfirst" boatbuilding from the last two hundred years. It also offers an analysis of the structural integrity and strength of vernacular boats and shows how the structure of boats has evolved across time to incorporate new techniques and changes in boat function.

A systems approach to documentary maritime fraud

Kapoor, Peter January 1987 (has links)
Wring the last decade documentary maritime fraud has caused considerable financial loss. The internationality of the crime and the difficulties experienced in the investigation and prosecution of offenders has caused serious concern both nationally and internationally. The aim of this research was to examine the system of international trade in terms of flow between institutions, and to develop a model of the system to identify areas of system failures in terms of actual or potential frauds. A database consisting of 101 fraud cases was compiled. Detailed examination of the cases identified features common to different classes of fraud. Systems approach was used to investigate the system with particular reference to Bills of Lading and method of payment under documentary credits. Conceptual mcdels of the three main contractual sub-systems i. e. carriage, insurance and payment, and of the total system were developed. The latter was used in conjunction with the database to pin-point the weak links both within the system and its imiediate envirormLent. Using a rwlti-disciplinary international Panel of Experts the Delphi technique, appropriately modified, was employed to test the hypothesised weak links, determine feasibility of implementing the recoamndations and seek information to assist in introducing measures to combat fraud. The analysis supports the hypothesised weak links identified in the environment and reccmuendations to strengthen them. Factors creating an environment for fraud are identified, along with reasons for not reporting the crime. Information required to combat fraud is identified. Prior to payment under documentary credits banks should carry out factual checks. The Bill of Lading is not a weak link but the people handling the document are unaware of its importance. Establishmnt of a Conmrcial Crim Research Unit specialising in international trade is recamrended, as is the development of an educational prograrmTo to increase conmercial awareness.

Risk factor analysis, continuous monitoring and root cause analysis for Teekay Shipping

Chen, Shengyuan 05 1900 (has links)
This thesis is based on an industry project with Teekay Shipping Co ., which is an international transportation service provider for oil companies, refiners and traders. Teekay is interested in knowing which factors contribute most to its operating incidents and accidents. Based on available data, namely vessel name, team, type, hull, and age, as well as incident and accident records, we quantified in this thesis the effects of these factors on the incident and accident frequency. The thesis presented the technical details of the Poisson regression analysis, which we used for quantifying the risk factors. Teekay is also interested in having a consistent method to present Teekay's overall risk picture, and to indicate best investment areas for its risk reducing purpose. Teekay has already implemented an Online Root Cause Analyses (ORCA) system, which collects the direct cause and root cause soon after an incident happens. We reviewed the ORCA system and made suggestions about certain parts of the system which were subsequently revised. Furthermore, we designed a bubble chart tool to present the overall risk faced by Teekay. The bubble chart tool has the capacity to indicate best investment areas clearly, and it is consistent over time, thereby enabling Teekay to evaluate easily the risk mitigation effect of its earlier investment in risk management. Finally, we designed a continuous monitoring tool, which allows Teekay managers to interactively explore the relationships among near misses, incidents and accidents, and to compare event frequencies of various vessel groups, such as vessel team, age, type and hull structure. The powerful continuous monitoring tool provides Teekay managers a full- range view of the risks the company faces. The design and the sample usage of this continuous monitoring tool are discussed in this thesis.

Laivo įkeitimo ir pirkimo - pardavimo sutarčių ypatumai / Peculiarities of ship mortgage deed and sale-purchase contracts

Martinauskaitė, Daina 05 May 2006 (has links)
Lietuvos Respublikos Prekybinės laivybos įstatymas pateikia laivo sąvoką: :laivas- bet kurio tipo savaeigis ar nesavaeigis plaukiojantis statinys, kuris yra ar gali būti naudojamas laivybai. Laivai, išskyrus karo laivus, pakrančių apsaugos laivus, registruojami vidaus arba jūrų laivų registruose. Rašant šį darbą pirmiausiai reikėjo išspręsti klausimą, kokios rūšies laivai bus šio darbo objektas. Dėl skirtingo šių laivų teisinio reglamentavimo šio darbo apimtis būtų per didelė. Todėl rašysime tik apie jūrinius laivus, kuriuos Lietuvos Respublikos civilinis kodeksas pripažįsta nekilnojamaisiais daiktais. Kitas kriterijus, kodėl nagrinėsime tik jūrinius laivus yra jų vertė. Jūriniai laivai lyginant su vidaus vandenų laivais yra žymiai didesnės vertės. Naujų laivų vertė siekia net milijonus litų. Sandoriai, kurie susiję su jūriniais laivais turi būti sudaromi labai apgalvotai, iki smulkmenų numatant sutarčių sąlygas, nes ateityje kilsiantys ginčai gali sukelti didelių nuostolių šalims. / Ships are goods, which participate in shipping industry as the most powerfull subjects. Contracts with ships are regulated all over the worl, mostly in marine countries. Ship mortgages, sale and purchase agreements are most risky contracts which needs strong financial support. Without some kind of security, investors will never enter into risky market. Ship are goods with great value tahts why law of ship mortages and sale need to be regulated properly with national and international legislation. This issue will focus on the law of ship mortages and sale contract in Lithuania. It will take a comparitive legal approach, comparison with the laws of the most developed common law countries in both marine legislation and shipping.-Canada, U.K.,USA And civil law countries Germany, Russian Federation.

Portuguese Ships on Japanese Namban Screens

Yamafune, Kotaro 2012 August 1900 (has links)
Namban screens are a well-known Japanese art form that was produced between the end of the 16th century and throughout the 17th century. More than 90 of these screens survive today. They possess substantial historical value because they display scenes of the first European activities in Japan. Among the subjects depicted on Namban screens, some of the most intriguing are ships: the European ships of the Age of Discovery. Namban screens were created by skillful Japanese traditional painters who had the utmost respect for detail, and yet the European ships they depicted are often anachronistic and strangely. On maps of the Age of Discovery, the author discovered representations of ships that are remarkably similar to the ships represented on the Namban screens. Considering the hypothesis that ships of some of the Namban screens are copies of ships represented on contemporary European cartography, the author realized that one particular historical event connecting Europe and Japan may be the source of these representations. This was the first visit of the Japanese Christian embassy, the Tensho Embassy, to Rome, in 1582. Its journey to Europe and its following visit to the Taiko, or first effective leader of Japan, Hideyoshi Toyotomi, may have been a trigger for the production of one of the most well-known Japanese artworks, the Namban screens.

Cruising with containers : a qualitative investigation of the lived experience of passenger freighter travel

Szarycz, Gregory Simon, n/a January 2007 (has links)
This thesis is the result of a preliminary investigation into a niche market segment of the maritime tourism economy. Travel by working class freighter or cargo ship is not a new activity; however, the concept of freighter-based tourism (wherein participants travel by container ship in their free time solely for leisure purposes) has emerged relatively recently on the tourism spectrum. A major cause of its recent popularity and allied growth is the positive word of mouth promotion which has been generated by people who try freighter cruising and like it. As the number of prospective travellers increases, merchant shipping lines are seeing dramatic changes in the makeup of their passenger lists. In former years, the typical freighter 'passenger' spanned all ages and walks of life, as thousands of European immigrants traversed the Atlantic in search of a new life in the Americas. Today�s freighter 'travellers' are almost always over 50 years of age (up to a maximum age of 79) and are, for the most part, affluent with time and money to spare. Freighter travel nowadays involves the movement of people solely for the purpose of a unique and atypical travel experience. The purpose of this qualitative study was to explore the experiences of 22 participants engaged in recreational travel aboard working container vessels/cargo ships. The research questions driving this study were: What expectations and factors are understood by passengers to influence their decision to choose this particular mode of transport? What is the nature of the freighter experience, as passengers themselves understand it? What meanings do passengers attach to their experiences? How do the temporal dimensions of the passenger freighter experience (before, during, and after) connect with each other? This study employed a qualitative methodology to capture and portray as vividly as possible the participants� experiences and their attempts to make sense of those experiences. A phenomenological case study research design, set within a symbolic interactionist analytical framework, guided the study. The data consisted of in-depth online interviews and document analysis in the form of unsolicited travelogues/journey diaries. Through a prolonged and iterative process of data analysis using the transcendental phenomenological model provided by Moustakas (1994) and the operational refinements suggested by Schutz (1970) and Kvale (1995), the researcher documented the 'lived experience' of travel by cargo ship from the individual travellers� perspectives. Further, as a tool for describing, analysing, and interpreting the data, this study utilised the 'generic social processes scheme', a sociological method for the purposes of organising, analysing and interpreting qualitative data (Prus 1996). Within this research the themes were presented collectively, although they were systematically identified separately. The shared themes, meanings and patterns that shaped the informants� travel narratives suggested that moving out to the unfamiliar can be frightening, or it can be liberating. Participants had assessed and realistically accepted the potential hazards of a freighter voyage, working on the assumption that a willingness to roll with uncertainty, unexpected delays, and mishaps is mandatory. Associated with these themes were issues of adaptation; dealing with challenges, ambiguities and constraints, which, despite their potential to preclude further similar such involvements, shaped the overall freighter travel experience and did not affect participants� satisfaction with the experience. It was further shown that freighter travellers are highly individualised people characterised by their interest in unique 'life experiences' and defined by their search for the 'extraordinary'. Participants framed their behaviours as an extension of themselves; their self-designation as 'travellers' and not 'tourists' and their emphasis on independence and autonomy conferred a sense of individuality and personal determination. Like Cohen�s (1976) non-institutionalised, unstructured tourists, these 'travellers' valued risk, adventure and novelty. The idea of negotiation through ambiguity and occasional setbacks in their travels further challenges commonly held perceptions about constraints, which, too often is seems, have been construed as obstacles or barriers (Jackson 2000) to travel. With regard to the present study, constraints, while inherent to freighter travel, would not have represented a full or accurate picture of the travellers� experiences without a concomitant description of how they were negotiated; moreover, the process of their negotiation repositions these travellers as active participants (instead of inactive consumers) of the tourist experience. These travellers decided what they wanted to do, where they wanted to go, and ensured they could negotiate their constraints to do so. The conclusive findings of this study suggest that freighter travel was viewed largely as a positive, beneficial, and rewarding experience, offering opportunities for self-development, reflection, social interaction, and cross-cultural immersion and learning. While certain constraints and limitations were acknowledged and recognised, freighter travellers negotiated through them, and fully enjoyed participation in the travel experience.
