Cost Estimates for Flood Resilience and Protection Strategies in New York City

In the aftermaths of Hurricanes Irene, in 2011, and Sandy, in 2012, New York City has come to recognize the critical need to better prepare for future storm surges and to anticipate future trends, such as climate change and socio-economic developments. The research presented in this report assesses the costs of six different flood management strategies to anticipate long-term challenges the City will face. The proposed strategies vary from increasing resilience by upgrading building codes and introducing small scale protection measures, to creating green infrastructure as buffer zones and large protective engineering works such as storm surge barriers. The initial investment costs of alternative strategies vary between $11.6 and$23.8 bn, maximally. We show that a hybrid solution, combining protection of critical infrastructure and resilience measures that can be upgraded over time, is less expensive. However, with increasing risk in the future, storm surge barriers may become cost-effective, as they can provide protection to the largest areas in both New York and New Jersey. © 2013 New York Academy of Sciences

The power of creative thinking in situations of uncertainties: the almost impossible task of protecting critical infrastructures

A good and scientific analysis starts with a closer look at the conceptualisation at hand. The definition of CIP is not easy because of its wide range. This paper examines infrastructures that are critical and need protection. Each word entails a specific connotation and is characterized by several components

Vulnerability of the Emirati Energy Sector for Disaster: A Critical Review

Infrastructure in all its forms is a valuable asset and vulnerable to any natural or manmade hazard. The protection of infrastructure is thus one of the most important and difficult tasks for any government. The energy sector dominates in the UAE and consists of various assets - electricity, oil and natural gas that are geographically dispersed and connected by systems and networks. The protection of these systems and assets and within the energy sector especially, the safeguarding of oil and gas infrastructure from any and all internal and external threats should become top priority in the UAE. Threats to geopolitical and economic stability that need to be considered and prepared for include tectonic activity, climate change, nuclear energy, terrorism and war. This paper explores the disaster vulnerability of the Emirati energy sector with specific focus on Abu Dhabi and Dubai cities. It is based on secondary data, taken from various academic and professional sources, and primary data from a questionnaire survey administered on site at two electricity-generating plants in Abu Dhabi and Dubai. Forty questionnaires were distributed and 35 were returned back- 20 Abu Dhabi and 15 Dubai. Oil and gas sectors were identified as the most vulnerable energy sources in both Abu-Dhabi and Dubai. Risk from terrorism was thought to be the greatest hazard with every single respondent choosing it. This was despite the fact that respondents believe it to be one of the threats that the energy sector is prepared for

Building Disaster Resilience within the Emirati Energy Sector through a Comprehensive Strategic Mitigation Plan

Disasters, both natural and man-made, have been occurring with increasing frequency and effect in recent decades in many countries around the world. Such threats have been shown to result in a loss of life, property and income and all of which have an impact on the country’s socio-economic structure and geo-political positioning. The UAE is steadily adapting its policies and practices to manage any potential disaster, whether natural or man-made. However, evidently the UAE is exposed and vulnerable to tectonic activity from a number of sources and yet there is little in the form of seismic detection, protection, resistance or design for some of the newest and tallest structures in the world. The paper highlights the importance of the strategic mitigation planning for disaster resilience within the Emirati Energy sector. It discusses the issue of disaster globally and then specifically with regards to the UAE, forming a critical analysis on crisis and its management. A broad literature review of the problems readily associated within the discourse is undertaken so that the definition, classification and the application of the disaster and its management cycle are appropriately contextualised in regards to the Emirati problem. The window of opportunity that the UAE has for improvement is emphasised by the findings of this paper

Impact Assessment of Hypothesized Cyberattacks on Interconnected Bulk Power Systems

The first-ever Ukraine cyberattack on power grid has proven its devastation by hacking into their critical cyber assets. With administrative privileges accessing substation networks/local control centers, one intelligent way of coordinated cyberattacks is to execute a series of disruptive switching executions on multiple substations using compromised supervisory control and data acquisition (SCADA) systems. These actions can cause significant impacts to an interconnected power grid. Unlike the previous power blackouts, such high-impact initiating events can aggravate operating conditions, initiating instability that may lead to system-wide cascading failure. A systemic evaluation of "nightmare" scenarios is highly desirable for asset owners to manage and prioritize the maintenance and investment in protecting their cyberinfrastructure. This survey paper is a conceptual expansion of real-time monitoring, anomaly detection, impact analyses, and mitigation (RAIM) framework that emphasizes on the resulting impacts, both on steady-state and dynamic aspects of power system stability. Hypothetically, we associate the combinatorial analyses of steady state on substations/components outages and dynamics of the sequential switching orders as part of the permutation. The expanded framework includes (1) critical/noncritical combination verification, (2) cascade confirmation, and (3) combination re-evaluation. This paper ends with a discussion of the open issues for metrics and future design pertaining the impact quantification of cyber-related contingencies
