Green water and loading on high speed containerships

Pham, Xuan Phuc January 2008 (has links)
Green water problem and its loading effects on high speed containerships was investigated with the purpose of developing a modelling framework that can practically guide naval architects to a better understanding of this problem and improvements in design. The research began by reviewing extensive publications relevant to the understanding of green water, limitations in the ways the problem had been addressed and establishing a methodology that could effectively unlock the physics and efficiently solve the problem. As a first step, a summarised background to how green water started, developed and finally took place was presented. An experimental programme was then implemented in order to observe the occurrence and to explore the physics behind these events. From the outcome of the experiments, it was obvious that green water modelling could be developed and solved by Computational Fluid Dynamics (CFD) technique through Volume of Fluid (VoF) method. To provide a starting point for this research, theoretical background of CFD was briefly introduced. Furthermore, in order to validate this approach, two benchmark tests were implemented and compared with published experimental data. It showed that in both cases, the simulation could accurately reproduce the results obtained from experiments. Following this analysis, research continued to expand the CFD simulation to modelling of green water. Due to the complex and random nature of green water, development of the simulation framework was semi-empirical and based partly on experimental data. A pure theoretical approach could have been adopted. However, taking into consideration current limitations in ship motion prediction theories and sensitivity of green water to elemental factors, it was justified that semi-empirical approach was appropriate. The simulation was conducted and the output results were compared with experimental results for a variety of test conditions that involved ship velocity, wave height and period. Good agreement between simulation and experiment was obtained. For all loading cases, experimental results were reproduced fairly well. This suggested that the modelling framework was adequate for all practical purposes. Investigation was also conducted on a series of rectangular breakwaters that were fitted on the forecastle deck. Changes in water behaviour and loading following changes in the breakwater were well reflected. This implied that instead of a rectangular breakwater, the simulation model could also be applied to other types of breakwaters. The results suggested that the simulation methodology has many practical applications. Within naval architecture, it can be used to perform parametric studies in order to select an optimal design of breakwater for a ship. In other sectors such as coastal engineering, the methodology can be adopted to investigate the interaction between water surge and a seawall or offshore breakwater. In conclusion, it was found that the developed modelling framework shows potential for simple modelling of green water in which the behaviour of the water and its loading effects could be well reflected. It was further concluded that, provided appropriate principles are applied, the methodology has potential for other engineering applications. While it is acknowledged that current model may be limited by its semi-empirical basis and issues associated with computational requirements, it is noted that considerable possibilities for future research and development remains to be explored.

Sharpening the trident : the decisions of 1889 and the creation of modern seapower

Mullins, Robert Edward January 2000 (has links)
It was a year of decisions that heralded the pre-dreadnought era, perhaps the least understood chapter of modern naval history. In March 1889, the Salisbury ministry officially endorsed what later became the Naval Defence Act, which in its final form authorised the largest shipbuilding programme of its kind in the nineteenth century. When it was finally completed five years later, the Royal Navy would have a new fleet based around 10 battleships, 42 cruisers and 18 torpedo gunboats, all of the latest design and at a cost of £21,500,000. Then, in December 1889, the Harrison administration sought legislative approval to adopt a forward offensive naval strategy, complete with a fleet of battleships and armoured cruisers in an unprecedented shift in American naval policy. This strategic rationale provided the intellectual framework to transform the United States into a modern seapower. The purpose of this comparative study is to revisit the decisions of 1889, with the benefit of underutilised archival sources and an innovative research methodology recently embraced by the naval historical community. Whereas prior accounts of these decisions generally assess their historical significance in terms of the naval construction that ensued in the pre-dreadnought era, this thesis focuses instead on the pervasive influence of strategic ideas and how strongly they affected the personalities, institutions and events that shaped the respective outcomes in both London and Washington. That strategic ideas shared among naval officers can be decisive in this regard is the underlying tenet behind the cultural approach to historical naval analysis, which is introduced here to highlight the impact of organisational cultures upon the strategic and force structure choices of military organisations.

Ultimate strength of ship structures including thermal and corrosion effects : a time variant reliability based approach

Moatsos, Ioannis January 2005 (has links)
On December 17th 2002 the World Meteorological Organization issued a statement according to which the global mean surface temperature has risen and consequently 2002 was the warmest year in the 1961-2002 period.  Positive sea surface temperature anomalies across much of the land and sea surface of the globe in general contributed to the near record temperature ranking for the year along with climate anomalies in many regions across the globe.  Climate change as a result of global warming is a worldwide occurring phenomenon which the experts have only recently started to understand and which affects and significantly will affect us in the near future.  The effects of climate change have been somehow neglected by the ship and offshore related academic and research communities. In the case of thermal effects on ships structures, unless the problem solved is temperature dependent, this type of stress has often been neglected and not been taken into account in most types of analysis.  The most likely reason behind this would seem to be that the stresses produced from temperature changes would be too small to be taken into account compared with still water loads or wave bending stresses.  This is not the case though.  Records exist of ships having broken in half while moored in still water and major hull factures occurred in still water while the temperature was changing as it can be seen from the relevant published literature.  Very little work on thermal stress on ship structures has been published since the 1950s and 1960s and no work has been done that considers temperature effects on ultimate strength. Research undertaken aims to incorporate temperature effects on existing ultimate strength formulation by using a thermal stress approach, compare and use recently proposed corrosion models to model corrosion effects on ultimate strength and provide a foundation on which reliability analysis could then be performed for Tanker/FPSO structures operating in the North Sea.  After comparing a number of possible approaches that would enable to loading components to be combined in a stochastic fashion, the loading part of the reliability analysis is handled using extreme wave statistics and the Ferry Borges-Castanheta load combination method. Annual reliability indices and probabilities of failure are calculated for hogging and sagging conditions using both time-variant and time-invariant approaches and a variety of reliability analysis approaches showing the effects of temperature along with partial Safety Factors for all variables taken into account.
