Study on Generator Self-Excitation in Offshore Oil Platform Power System
Computer Simulation, 2012Co-Authors: Zhang GuominAbstract:When the Offshore Oil platform power system black-start,submarine cables for long-distance need to put in,the self-excitation of generator happen easily,which is bad to generator and other electrical equipments.But analyzing and inhibiting measures of self-excitation for land power system are not fit for island power system.According to the characteristics of Offshore Oil platform power system,the paper presented a suitable method for the Offshore Oil platform power system to restrain generator self-excitation.First,the paper introduced the basic principle and criterion of synchronous generator's self-excitation based on armature reaction of synchronous generator.The Louts criterion was used to get judgment basis and conditions of generator parameter in producing synchronous self-excitation.In one Offshore Oil platform power system,for example,the measures was posed through analysis of self-excitation in the Offshore Oil platform power system.Then the black-start path was simulated and calculated by PSCAD/EMTDC.The computer simulation result illustrates the effectiveness of the proposed method.

Offshore Oil spill response practices and emerging challenges
Marine Pollution Bulletin, 2016Co-Authors: Pu Li, Bing Chen, Baiyu ZhangAbstract:Offshore Oil spills are of tremendous concern due to their potential impact on economic and ecological systems. A number of major Oil spills triggered worldwide consciousness of Oil spill preparedness and response. Challenges remain in diverse aspects such as Oil spill monitoring, analysis, assessment, contingency planning, response, cleanup, and decision support. This article provides a comprehensive review of the current situations and impacts of Offshore Oil spills, as well as the policies and technologies in Offshore Oil spill response and countermeasures. Correspondingly, new strategies and a decision support framework are recommended for improving the capacities and effectiveness of Oil spill response and countermeasures. In addition, the emerging challenges in cold and harsh environments are reviewed with recommendations due to increasing risk of Oil spills in the northern regions from the expansion of the Arctic Passage.

Development of an integrated decision support system for supporting Offshore Oil spill response in harsh environments
2014Co-Authors: Pu LiAbstract:Offshore Oil spills can lead to significantly negative impacts on socio-economy and constitute a direct hazard to the marine environment and human health. The response to an Oil spill usually consists of a series of dynamic, time-sensitive, multi-faceted and complex processes subject to various constraints and challenges. In the past decades, many models have been developed mainly focusing on individual processes including Oil weathering simulation, impact assessment, and clean-up optimization. However, to date, research on integration of Offshore Oil spill vulnerability analysis, process simulation and operation optimization is still lacking. Such deficiency could be more influential in harsh environments. It becomes noticeably critical and urgent to develop new methodologies and improve technical capacities of Offshore Oil spill responses. Therefore, this proposed research aims at developing an integrated decision support system for supporting Offshore Oil spill responses especially in harsh environments (DSS-OSRH). Such a DSS consists of Offshore Oil spill vulnerability analysis, response technologies screening, and simulation-optimization coupling. The uncertainties and/or dynamics have been quantitatively reflected throughout the modeling processes. First, a Monte Carlo simulation based two-stage adaptive resonance theory mapping (MC-TSAM) approach has been developed. A real-world case study was applied for Offshore Oil spill vulnerability index (OSVI) classification in the south coast of Newfoundland to demonstrate this approach. Furthermore, a Monte Carlo simulation based integrated rule-based fuzzy adaptive resonance theory mapping (MC-IRFAM) approach has been developed for screening and ranking for spill response and clean-up technologies. The feasibility of the MC-IRFAM was tested with a case of screening and ranking response technologies in an Offshore Oil spill event. A novel Monte Carlo simulation based dynamic mixed integer nonlinear programming (MC-DMINP) approach has also been developed for the simulation-optimization coupling in Offshore Oil spill responses. To demonstrate this approach, a case study was conducted in device allocation and Oil recovery in an Offshore Oil spill event. Finally, the DSS-OSRH has been developed based on the integration of MC-TSAM, MC-IRFAM, AND MC-DSINP. To demonstrate its feasibility, a case study was conducted in the decision support during Offshore Oil spill response in the south coast of Newfoundland. The developed approaches and DSS are the first of their kinds to date targeting Offshore Oil spill responses. The novelty can be reflected from the following aspects: 1) an innovative MC-TSAM approach for Offshore OSVI classification under complexity and uncertainty; 2) a new MC-IRFAM approach for Oil spill response technologies classification and ranking with uncertain information; 3) a novel MC-DMINP simulation-optimization coupling approach for Offshore Oil spill response operation and resource allocation under uncertainty; and 4) an innovational DSS-OSRH which consists of the MC-TSAM, MC-IRFAM, MC-DMINP, supporting decision making throughout the Offshore Oil spill response processes. These methods are particularly suitable for Offshore Oil spill responses in harsh environments such as the Offshore areas of Newfoundland and Labrador (NL). The research will also promote the understanding of the processes of Oil transport and fate and the impacts to the affected Offshore and shoreline area. The methodologies will be capable of providing modeling tools for other related areas that require timely and effective decisions under complexity and uncertainty.

Offshore Oil Terminals—Potential Role in U.S. Petroleum Distribution
1991Co-Authors: Larry Maloney, Edward WallAbstract:The construction of port facilities in deep water, several miles seaward from the nations's coastline, is one of the measures that have been suggested for reducing Oil tanker accidents. This paper briefly describes the issues associated with such ports (referred to as Offshore Oil terminals), including their estimated construction and operating costs, siting and operating constraints, and environmental and economic factors associated with their operation. Such Offshore Oil terminals would be constructed several miles Offshore in deep water and would be designed to accommodate the largest classes of Oil tankers in operation. To date, only one such Offshore terminal -- the Louisiana Offshore Oil Port (LOOP) -- has been constructed and is operating in the United States. The LOOP, located in deep water 18 miles off the coast of Louisiana, became fully operational in 1982.
