The quality of the fuel oil provided will ensure the safe operation of vessels. Shipping companies under their fuel oil management programme confirm that the quality and quantity of fuel oil provided are as requested. To be certain of the quality and quantity loaded, correctly performed bunkering procedures need to be integrated in the fuel oil management programme. The data collected through them will prove more than useful when a dispute arises either in terms of fuel oil quality or the loaded quantity. Ship emissions to air are a concern of IMO and recently the European Union, as the shipping industry contrary to land-based industries is not yet subject to any regulations to reduce emissions. Sulphur oxides are targeted as they depend on the sulphur content of the fuel oil. Identical limits are set by both the IMO and the EU, but IMO's regulations are yet to be ratified and EU will not accept any vessels travelling within its waters to bum high-sulphur fuel oil from 2010 onwards. Till then, those involved in the matter might have to consider implementing an emissions trading scheme, as in the land-based industries, as a more viable option to capping sulphur content. Every shipowner is aware of the fact that the single most costly and highly volatile running cost paid is the cost of bunkers. The options available to him/her are hedging instruments such as futures and OTC products. When used effectively along with freight futures, although not yet commonly available, shipping companies may reduce their risk exposure and enhance their profits. / (cont.) When purchasing fuel oil from a number of ports, cost savings may be augmented by a carefully improvised bunkering planning, as well as negotiating the price of fuel oil purchased based on its density, aluminum content, viscosity, water content and net specific energy. / by Angelos Boutsikas. / S.M.

In this dissertation, a high-order spectral-element (HOSE) method is developed to investigate problems about nonlinear waves. An exponentially converging algorithm, it is able to be applied to solve nonlinear interactions between waves and submerged or surface-piercing bodies with high-order nonlinear effects. The HOSE method is applied to investigate dynamics of nonlinear waves and their interactions with obstacles. We first implement it to calculate the hydrodynamic forces and moments on a fixed underwater spheroid, with uniform current, different angles of attack and finite water depth included in the study. Extending this study to wave interaction with tethered bodies, we create an efficient simulation capability of moored buoys. Coupling the HOSE method with a robust implicit finite-difference solver of highly-extensible cables, our results show chaotic buoy motions and the ability for short wave generation. We then focus our attention on the free-surface patterns caused by nonlinear wave-wave and wave-body interactions. Starting with a two-dimensional canonical problem about the wave diffraction and radiation of a submerged circular cylinder, numerical evidences are obtained to corroborate that, for a fixed cylinder, a cylinder undergoing forced circular motion, or free to respond to incident waves, the progressive disturbances are in one direction only. The three-dimensional wave-wave interactions are studied. It is proved both analytically and numerically that new propagating waves could be generated by the resonant interactions between Kelvin ship waves and ambient waves. Another consequence of resonant wave-wave interactions is the instability of free-surface waves. In this dissertation, the three-dimensional unstable modes of plane standing waves and standing waves in a circular basin are identified numerically and then confirmed analytically. These investigations cover a large variety of nonlinear-wave problems and prove that the HOSE method is an efficient tool in studying scientific or practical problems. / by Qiang Zhu. / Ph.D.

The question of rights over information is correspondingly becoming more complicated as well. Regulation over cyberspace is inconsistent, and continues to develop in piecemeal fashion, while the debate remains unsettled whether cyberspace should be regulated at all. Currently no overall legal design for cyberspace is in view. Meanwhile, recent studies report that self-regulation in cyberspace has failed to protect even basic rights of privacy with respect to information. An investigation was made to evaluate the 1983 United Nations Convention on the Law of the Sea as a prototype for a cyberspace legal regime. The provisions for the high seas were found to be readily adaptable for parallel rules for cyberspace. Likewise, the Part XI provisions concerning the deep sea bed, provided for a very detailed organizational framework from which an international and coordinated management of information transactions in cyberspace may be pursued. The detailed provisions regarding settlement dispute were almost directly applicable to cyberspace, with little if any modification. A cyberspace legal regime modeled from the Law of the Sea would eliminate some of the jurisdiction, accountability, and enforcement difficulties of Internet regulation. / by Raymond K. Joe. / S.M.
