大型石化港区安全风险评估指标体系与评估方法

针对大型石化港区安全风险评估实践中评估层次不分明、重点不突出、措施针对性不强的问题,构建了以风险特征、风险防控能力、区域应急能力等为基本指标的指标体系,基于层次分析法建立了安全风险计算数学模型。结合国内大型石化港区安全管理现状提出了安全风险分级划分标准,最终实现了对大型石化港区区域安全风险水平的量化评估。将此方法应用于某典型大型石化港区的安全风险评估,得出其区域安全风险为等级Ⅲ(较大风险)的结论。

Corporatization: a legislative framework for port inefficiencies

It is now some five years since the restructure of Australian ports and their transformation into corporatized entities. This strategy was adopted in an endeavour to improve efficiency by distancing government from day to day operations—the element that was perceived by many to be the cause of sub-optimal performance. While there is widespread agreement that port performance has improved significantly, dissatisfaction persists with the continued political intervention which is considered to be the reason for ongoing sub-optimal performance and ports' commercial potential from being realized. This paper investigates some of these issues but argues that political intervention per se should not be the focus of research and what is widely perceived to be the cause of the problem. Rather, that political intervention is an effect of something more endemic, of a legislative framework which may not be appropriate for the operations of a commercially focused port. It is argued that the focus should therefore be on the cause, a legislative framework, rather than the outworkings, or the effects of that framework.

Information technology network security risk assessment and management framework for shipping companies

Shipping companies are high-vulnerability information handling organizations (HIHOs). In the past, such companies used exclusively HIHO private communication networks and own satellite resources in order to share and transport sensitive information. In recent years, the ability for the HIHO network users to exploit the advantages of the low-vulnerability information handling organizations' (LIHOs) value added networks, has led to the need for augmentation of the HIHO networks. In the maritime sector, a push-and-pull effect on the need and demand to transfer information onboard and ashore has led many companies to experiment with interconnected HIHO and LIHO open distributed systems and networks, for their ship-to-shore communications. Security then becomes an issue in a domain, onboard-ashore data transmissions, where little information on the level of risk is available. This paper proposes a risk assessment and management framework to assist in countermeasure selection and level of LIHO network use definition. The model is ultimately applicable where information on potential risks and their impact is minimum and simultaneously changeable. The model is connected to a security profile for interconnected HIHO and LIHO open distributed systems and networks.

罗泾港区二期工程矿石堆场堆取料机基础设计

由于工期限制,罗泾港区矿石堆场堆取料机基础建在使用期持续沉降变形(3 m左右)的软弱地基上。针对使用期地基沉降变形,设计了使用期可调整的堆取料机基础结构,并给出了堆取料机基础使用期验评标准。设计认为传递到深层土体的堆场矿石荷载是平衡的,皮带机系统轴线水平位移是由于传递到上层土体的堆场矿石荷载不平衡导致上层土体变形而产生的,提出加筋垫层可以消除皮带机系统轴线横向变形。
