Pembina Pipeline Corporation (Pembina) owns and operates close to 10,000 km of crude, natural gas liquids (NGL), and natural gas pipelines across North America, with the majority of assets in western Alberta and eastern British Columbia. The Pembina pipeline network includes over 1,600 river and stream crossings, most of which are subject to varying degrees of vertical and/or lateral erosion. 1,260 crossings were in Alberta at the onset of the study. Identifying potential lateral erosion hazards is a critical component of geohazard management program for pipeline integrity. In 2012, Pembina initiated a three-phase program to proactively address lateral-stability issues at river and stream crossings in Alberta: phase one identified and short-listed crossings that have potential lateral channel-shifting problems; phase two assessed which short-listed crossings have insufficient cover depth to accommodate the potential channel-shifting activities and ranked these crossings as high risk of exposure; and phase three will develop plans for repair and/or replacement of the high-risk crossings. Through this program, Pembina explores the significance of lateral erosion and encroachment at pipeline water crossings of various vintages, with regards to pipeline integrity. This paper provides discussion as to how crossing geohazard risks are identified, with particular emphasis on stream bank erosion, and how this fits into Pembina’s overall risk management program. As well, selected case studies are provided.

The development of effective hazard trees assessment practices has been an important focus of urban forestry for many years. When a publicly owned tree fails and causes property damage, personal injury or death in the United States, a potential consequence for a government agency is litigation. Although managing a large public tree resource can seem daunting, simple assessment parameters can be used to identify high-risk features within the tree population. Through analysis of the interaction between high-risk elements in the tree population and definition of a long-term, managed approach to tree risk reduction, strong policies and practices can be initiated. This program emphasizes two concepts. First, implementation of a well thought out risk reduction strategy improves the overall health of the urban forest, which results in a safer urban environment. This goal is universal, regardless of national boundaries. Second, documentation and implementation of tree risk management policies forms the foundation for a government agency’s defense, if litigation ever occurred.

As risk assessment methodologies, tools, and processes continue to evolve in the industry, utilizing risk outputs to not only identify high risk locations, but to also understand the driver(s) behind the elevated risks for those locations is paramount. The ideal scenario for reducing pipeline risk is utilizing a risk-driven mitigation plan as this ensures the optimal use of company dollars, but also inherently means that a company has a firm understanding of their data and pipeline system. When the company understands their data and the implications for its inaccuracies, whether it be improper data alignment or incorrect application of data, they can effectively employ a campaign for preventative and mitigative measures (P&MM). However, if suspect data is used during a risk assessment, P&MM cannot accurately target risk drivers and high risk locations, making it challenging for the company to maximize their resources. For well over a year, an on-going partnership between AGL Resources Inc. (AGL) and Det Norske Veritas (U.S.A.), Inc. (DNV GL) has ensued to tailor a GIS-based risk management software solution for AGL. Through this collaboration among Integrity Management, Risk Management, IT, GIS, and Operations & Maintenance subject matter experts (SMEs) on both sides, one central hub of cross-functional pipeline knowledge was created. As a result, countless opportunities were exploited to identify supplementary data sources to employ new data manipulation techniques and processes, providing AGL with the foundation for such a risk-based Preventative & Mitigative Measure program. With the foundation laid and the proper risk elements present, AGL can now execute optimized risk-informed responses to identified high risk locations, pipeline segments, or pipeline systems. These optimized responses require an understanding of the types of P&MM available to reduce the threats and consequences, the costs involved for each P&MM implemented, and the utilization of a tool to allow various ‘what-if’ risk analyses to be conducted. Adopting and integrating this process as part of AGL’s risk management program allows them to capitalize on the maintenance dollars they spend while also reducing the potential hazards to the surrounding people, places and environment.

The article reveals the features of accounting and analytical support for entrepreneurial risk management. It was found that entrepreneurial risk is a certain act as a result of which the business entity may suffer losses. It is proved that entrepreneurial risks should be classified according to the specifics of origin, the specifics of the legal settlement, the specifics of industry affiliation, the specifics of the consequences, the specifics of the duration of the impact of entrepreneurial risk, the specifics of the expression of will, the specifics of the form, the specifics of the level of typicality, the specifics of the level of validity, the specifics of the possibility of assessing and resolving the impact, the specifics of the possibility of insuring entrepreneurial risks, the specifics of the occurrence of entrepreneurial risks by sources of origin, the specifics of the scale of the impact, the specifics of the level of losses and the specifics of character. It is established that the process of entrepreneurial risk management is the process of managing the activities of the business entity as a whole and its individual parts, and takes into account the management of not only existing risks but also potential entrepreneurial risks in space and time, that may occur in the future during entrepreneurial activities. It is determined that the process of entrepreneurial risk management should take into account the stage of preparation and implementation of appropriate measures to reduce the risk as a result of making erroneous decisions by business entities, the stage of reducing the impact of possible negative consequences that may occur, especially, if the entity operates in unexpected changes and alarming development trends, as well the stage of development and implementation of the Declaration on Risk Management and the Risk Management Program. It is established that the important information on which it is possible to estimate possibility of occurrence of entrepreneurial risks, is the accounting reporting. In the perspective of further research, it is recommended to study entrepreneurial risks in Ukraine in the context of such aspects as causes, consequences and management.

Generally, the higher education institutions and students have been significantly increased from year to years in order to meet the needs of global labor and develop the country's economy better. On the other hand, they also carry out teaching, research, community service, and commercial activities. This diversity of activities creates more risks diverse and complex as well as a wealth of opportunities for higher education institutions. A solution considered is by implementing the risk management as a new concept to understand and manage the risks associated with those activities and making new opportunities, is challenging and critical to preserving and protecting reputation, and resources of institutions. This article discussed the importance of the role of risk management and to implement a risk-management program in higher education institutions that have high expectations as a world-class education institution. The risk-management program is also more optimal if it supported by a good communication between all leaders and staffs in the organizational environment.
