Abstract Axial strain inspection using the AXISS™ is an established tool in the pipeline operator’s toolbox to assess pipeline geotechnical threats and other strain related events. Consequently, there is a large database of axial strain data for several different pipelines operating in different environments and from multiple inspections at the same geographical locations. The Cheecham slope, located south east of Fort McMurray, Alberta, is a known geohazard site crossed by six individual pipelines. The lines were constructed between 1999 and 2013 and have a size range of 10” to 36”. Five out of the six lines, 12” to 36”, have been inspected using the axial strain tool. The pipelines inspected cover a range of characteristics including, different vintages, pipe diameters and positions in the ROW. These differences, and the ILI runs provide an insight into the effect of a landslide event on the strain response of these pipelines. Axial strain measurement of the multiple pipelines in the Cheecham slope’s ROW allows: i) a direct comparison between lines ii) evaluation of the strain profile across the slope iii) assessment of the magnitude of the axial strain in terms of pipe characteristics e.g. pipe vintage and mechanical properties. More importantly, the axial strain data may provide an additional tool to assess the effectiveness of strain mitigation steps carried out over the years. An increase in the frequency of axial strain ILI runs resulted in additional data being available and more importantly data from run to run inspections spread over months or sometime years. A single run captures the strain at the time of inspection but run to run inspections provide an additional comparative tool to evaluate and monitor pipeline movement. Two out of the five lines inspected have run to run axial strain data. This paper takes the Cheecham slope as a case study to discuss the benefits of run comparison of ILI axial strain data either by comparing strain values of repeated runs for a single line or by the cross comparison of strain responses of different lines in the same ROW. The paper aims to demonstrate how run to run analysis of ILI axial strain data can be implemented as part of geohazard risk management program to asses strain risk profiles of these locations and to assess the effectiveness of strain mitigation programs previously undertaken by operators.

Geohazard Risk

A 1,050 km long 20” pipeline was constructed to transport natural gas from northern Argentina to the coast of Chile. On the Argentine side, significant portions of the route traverse rugged mountainous terrain subject to landslides, debris flows, flash floods, and earthquakes. On the Chilean side (situated up to 5,000 m above sea level), the pipeline crosses active faults and terminates at locations historically subject to tsunami. The pipeline began operation in 1999. An outburst flood in a steep mountain stream caused the pipeline to rupture in 2001. Reactivation of a large rock slide in 2002 caused a second rupture. It appeared that the original design had underestimated the route’s exposure to geohazards, and efforts were required to improve pipeline safety and reliability. A geohazard risk management program was initiated in April 2002. Geohazards were identified and characterized through airphoto interpretation and field inspection. Sites were initially ranked using semi-quantitative risk estimates. Risk cost-benefit analyses were used to select optimal risk control measures at high ranking geohazard sites. These included monitoring programs, reconstruction of stream crossings, reroutes, and in one instance, landslide avoidance using a horizontal directional drill. Risk control measures were implemented between 2002 and 2006, and additional efforts are ongoing. An updated assessment of geohazard exposure was completed in 2005 with the objective of quantifying the level of risk reduction that had been achieved and prioritizing further risk reduction efforts. This paper describes implementation of the geohazard risk management program using a case history format. It highlights the techniques used to control the range of hazard that were identified in 2002 and to quantify the improvements achieved by 2006. The paper concludes with an overview of additional risk reduction initiatives that are in progress or under consideration.

Low Performance

This is a case study of a construction product manufacturer’s effort to become a profitable manufacturer of roofing systems while providing a best value product to the client (best performance at the lowest cost.) The manufacturer was attempting to become successful with product performance in an industry where low performance of competing products brought a perceived high risk of nonperformance from clients. The manufacturer’s efforts included documentation of performance of their installed product, creating a risk management process, testing the risk management process and creating a supply chain structure which minimized the risk of both the manufacturer and the client. The key component of a best value manufacturer is the identification of the true buyer of their materials is the owner of the facility which buys their product and not the contractors. This paper documents the transformation from not having performance information to having documented performance on their product, developing a risk management program, and exercising their risk management program. This includes the formulation of a performance based contractor program and the application of the Performance Information Risk Management System (PIRMS.)

Harmful Effects

AbstractThis paper engages in a comparative-institutional analysis of the private and public risk-management programs of the drug isotretinoin, which are designed to prevent the undesired effects isotretinoin has on fetal development. This case study sheds light on the comparative effectiveness of private and public regulation in the pharmaceutical and healthcare markets. A range of evidence indicates that the private risk management program successful in reducing pregnancies and educating patients about the harmful effects isotretinoin can have on a fetus. These findings challenge a consensus found in the medical literature that the private program needed to be supplanted and contain implications for future risk-management policy in healthcare.

The Impact

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.
