An economic assessment of fluidized-bed boilers in Australian merchant ships

Fluidized-bed boiler systems have sparked the enthusiasm of many in the past few years as an answer to many technological problems as alternate energy sources are investigated. Although still barely out of the experimental stage, ship designers are mooting the possibility of fluidized-bed combustion technology being applied in ship propulsion. This paper outlines briefly its process and discusses the economics of such a venture.

为了对比分析千吨级单体圆舭船型、深V船型、穿浪双体船型、三体船的耐波性能,采用二维半理论方法计算各船型在迎浪规则波中的摇荡及首中尾部垂向加速度的频率响应函数,其中应用时域格林函数求解水动力系数,应用谱分析计算各船型在不规则波中的运动有义值.结果表明,几种千吨级高性能船在波浪中的纵向运动性能均比常规圆舭船型优,其中三体船纵向运动性能最佳.计算结果可为该吨级舰船平台选型提供技术支持.     

The link between economic and environmental performance of the top 10 U.S. ports

Ports currently face increasing demands to address a variety of environmental issues and achieve sustainability objectives. Using insights from the resource-based view of firms, this study examines the link between economic performance (EP) and environmental performance (ENP) of the top 10 U.S. seaports. Geospatial modeling is used to capture pollution incidents that can be geographically dispersed; in addition, both a bootstrap data envelopment analysis (DEA) approach and an undesirable DEA model are used to measure port ENP and EP. Our findings are in general consistent with assertions that positive EP can be attained in conjunction with good environmental practices. Ports’ capabilities of strategic capital investment in physical assets, collaborative interorganizational processes, and performance monitoring are essential, while they pursue both economic and environmental goals simultaneously.
