The paper presents a complete risk assessment system of urban natural gas network from seven modules. Pipeline hazard scenarios are analyzed and the reasons for seven modules risk assessment system model are presented. Based on objective data of various pipeline sections, the assessment system also allows sections of pipeline to be ranked into a risk hierarchy by using advanced scientific mathematical treatment methods. The system is displayed in geographic information system (GIS) platform, in order to implement data resource sharing and visualization of assessment results. Therefore, the dynamic and safety management of gas pipeline network is achieved and the safe and reliable operation of urban gas pipeline network can be ensured. An application based on a real case study was undertaken so that the effectiveness of the assessment system could be verified.

The absence of a regional, open water vessel collision risk assessment system endangers maritime traffic and hampers safety management. Most recent studies have analysed the risk of collision for a pair of vessels and propose micro-level risk models. This study proposes a new method that combines density complexity and a multi-vessel collision risk operator for assessing regional vessel collision risk. This regional model considers spatial and temporal features of vessel trajectory in an open water area and assesses multi-vessel near-miss collision risk through danger probabilities and possible consequences of collision risks via four types of possible relative striking positions. Finally, the clustering method of multi-vessel encountering risk, based on the proposed model, is used to identify high-risk collision areas, which allow reliable and accurate analysis to aid implementation of safety measures.

Natural gas pipeline network is one of the most important city lifeline. Because of the complex process of pipeline operation, there has not an authoritative and reliable way to detect leakage. Taking into account the current continuous progress of pipeline network simulation and mature of gas SCADA system, the fault of natural gas pipeline network can be diagnosed by pattern recognition method. The method takes full advantage of the existing detection technology and the actual condition of the pipe network. It is very useful for pipeline safety management and maintenance.

Coastal safety accidents are characterized by a high proportion of human negligence and repeated occurrences of accidents caused by the same factors. The Korea Coast Guard prepares and implements various countermeasures to prevent accidents at coastal safety accident sites. However, there is a shortage of safety facilities and safety management personnel according to the limited budget. In addition, the ability to be proactively and proactively respond is low due to the limitations of the coastal safety accident risk forecasting system, which relies on the meteorological warning of the Korea Meteorological Administration. In this study, as part of preparing the foundation for establishing a preemptive and active coastal safety management system that can manage accident-causing factors, predict and evaluate risk, and implement response and mitigation measures after an accident occurs before coastal safety accidents occur. The establishment of a risk assessment system was proposed. The main evaluation factors and indicators for risk assessment were established through the analysis of the status of coastal safety accidents. The risk assessment methodology was applied to 40 major hazardous areas designated and managed by the Korea Coast Guard.

Construction of the Northern Gas Pipeline (NGP) is a case study in safe, professional gas pipeline construction. Beginning with comprehensive and collaborative pre-planning to de-risk the project before construction; through to the holistic safety and wellbeing culture created and nurtured on site, every facet of the project has been subjected to strategic safety thinking, strong safety leadership and uncompromising safety management. And the results speak for themselves: • more than 400000 man hours and more than 280 days of physical construction activity with a total recordable frequency rate of zero (0) – no medical treatment or lost time injuries; • more than 5 million kilometres driven on the project (excluding third party transport) with no significant vehicle incidents; and • more than 53000 pipe joint movements with no dropped pipe. Through comprehensive upfront planning, strategic industry partnering and a relentless focus on safety leadership and management, this high-speed cross-country pipeline project has been successfully constructed through some of the harshest physical locations in Australia and achieved outstanding results in safety, productivity and quality. The construction of the NGP has set new benchmarks in pipeline safety performance and this paper is in recognition of our team, our customer, and the many project partners and suppliers that have helped make this possible.

Throughout the last two decades many attempts took place in order policy makers and researchers to be able to measure the energy security of supply of a particular country, region and corridor. This chapter is providing an overview presentation of the Energy Security Risk Assessment System (E.S.R.A.S.) which comprises the Module of Robust Decision Making (RDM) and the Module of Energy Security Indices Calculation (ESIC). Module 1 & 2 are briefly presented throughout section 2 and the application of Module 2 in nine case study countries is discussed at section 3. Finally, in the last section are the conclusions, which summarize the main points, arisen in this chapter.

In this paper a process framework was constructed for the inspection and assessment of urban gas pipeline. Take a certain gas pipeline network as an example, work directory for complete inspection was established as well as models for risk assessment. Feasible and effective rectification measures could be taken according to the relative importance of the results of the inspection and assessment. Some work in this paper could be adopted for the inspection and assessment of urban gas pipeline.
