Abstract This study presents the implementation of a multidisciplinary team approach to geohazard identification, characterization, assessment, and mitigation \, that includes landslide subject matter experts (SMEs) in geotechnical and hydrotechnical engineering and geology and pipeline stress analysis with the pipeline owner/operator (Owner). This approach provided targeted and programmatic geohazard training, identification, exploration, assessment, mitigation, and monitoring, and hase been coin as the “TIEAMM” approach. The Owner worked with the geohazard SMEs to develop a system-wide geohazard pipeline integrity management program, including a phased geohazard assessment along the right-of-way, office and field-based training for the local operations staff, risk-based design mitigation approaches, on-site construction support, and continued monitoring. The landslide discussed in this study is used as an example to demonstrate the TIEAMM approach; this site was identified by local operations staff, documenting differential movement of approximately 15 feet between November 2018 and February 2019. A more detailed geological exploration and assessment as well as a pipeline strain assessment was completed. The work allowed for mitigation efforts and corresponding costs to be optimized. The mitigation design was flexible to address ongoing monitoring, and then field-fit to address site conditions observed during the construction work. The approach to geohazard management completed for this site provided the data and information needed to make informed decisions to support targeted optimization for the scope and scale of mitigation work, and thereby avoided over-conservative (and thereby overly-costly) mitigation efforts.

This paper aims to present a methodology for use in construction planning named the Repetitive Scheduling Method (RSM). Students on a graduate level construction management program can learn how to create a RSM schedule to be applied to a real project. Typically, the Critical Path Method (CPM) is used to plan general construction projects. This paper presents a case study wherein a CPM diagram is transformed into a RSM schedule for use in the construction of a green condominium. RSM is the most suitable tool for planning repetitive projects like condominium buildings, apartment complexes, or real estate development projects. It utilizes an uninterrupted flow of resource concept in order to eliminate manpower-related resource wastage. As a result, construction productivity can be improved by using the right construction planning tool on the right project. Interested graduate students researching construction engineering can apply RSM on their repetitive projects in the future.

Integrity Management

In early 2005, Kuwait Oil Company (KOC) initiated a Total Pipeline Integrity Management System (TPIMS) implementation in order to carry out a major integrity assessment of its operating facilities, equipment, buried plant piping and pipeline network and to establish a continuing integrity management program. KOC Transit System is a complex infrastructure consisting of over three hundred pipelines, thousands of wellhead flow lines, and consumer and offshore lines for which there was a significant loss of data when the facilities were destroyed during a military invasion in 1990. An initial pipeline system assessment identified issues and actions regarding condition of the pipelines, corridors, requirements on in-line inspection (ILI), documentation, RISK assessment, status of international code compliance, and overall state of the system. Following recommendations from that initial assessment led to the development of a long term strategy; the execution of which required the implementation of a comprehensive integrity management program. This case study discusses the results obtained after five years of implementation of TPIMS at KOC. It will demonstrate some of the complex components involved in managing the integrity of the Transit System that have been made possible through the implementation of the system. The general concept and structure of TPIMS will be described, and how it deals with the complexity of the KOC pipeline system. The system made it possible to integrate and manage data from various sources, by conducting integrity assessment using ILI, Direct Assessment and hydrostatic testing, as well as structure a comprehensive RISK & Decision Support mechanism. This is one of the world’s first implementations of this magnitude which encompasses such a wide range of services and variables; all being managed in a single environment and utilized by a multitude of users in different areas at KOC. The biggest challenge in a project of this scope is data management. Examples will be shown of the integration structure to illustrate the benefits of using a single comprehensive and versatile platform to manage system requirements; ultimately providing system reliability and improving overall operational efficiency.

TransCanada Pipelines have been involved with monitoring environmental conditions at pipe depth for almost 10 years. The purpose of this monitoring is to understand the mechanism of SCC as it occurs in the field and to assist in the development of site-selection models for identifying locations where SCC might be occurring. Monitoring can either be done at many locations along the right-of-way at a given time or continuously at discrete locations in order to observe seasonal variations. A range of environmental parameters can be monitored. Early work focussed on parameters relevant to corrosion, such as soil resistivity, redox potential, temperature, pH, and on- and off-potentials. More recently, parameters relevant to SCC have also been monitored, such as soil CO2 and permeable hydrogen concentrations. In addition, the extent to which these parameters change seasonally has been monitored to determine if the environment is conducive to SCC continuously or whether cracking might only occur at certain times of the year. In terms of implementation, the results of in situ monitoring can be used as part of a larger integrity management program to decide where and when to mitigate SCC. Correlations between soil parameters measured using the portable probe and known SCC sites can be used to identify other susceptible locations or to prioritize different lines for inspection. Seasonal variations at a particular location can be used to derive effective crack growth rates from accelerated laboratory testing in order to determine re-inspection intervals. Examples are provided of both portable and permanent NOVAProbe measurements for low-pH and high-pH SCC.

Recent failures in seam weld pipe have raised concerns within the pipeline industry over the integrity of such welded pipe. Low-Frequency (LF) Electric Resistance Welded (ERW) pipe manufactured prior to 1970, in particular, can be susceptible to failures caused by hook cracks, lack of fusion and other planar defects should the weld area exhibit low toughness. Integrity management regulations and Pipeline operators are evaluating potential methodologies to address and mitigate the LF-ERW seam weld threat. A program has been initiated at Williams Northwest Pipeline GP (NWPGP) to address the integrity management of its pre-70s ERW pipelines. In this case study, as part of an overall integrity management program, a hydrostatic test and fatigue analysis based methodology for addressing the LF-ERW seam weld threat is presented. The methodology was applied to 15 pre-1970’s natural gas pipelines. The results and findings are summarized in terms of the integrity threat mitigation and maintenance strategies.

Colombia is a country located in a geographical area with great geological diversity, where every day the effects of climate change increases the probability of the failure of buried pipelines due to the movement of land or the instability associated with them. That is why the use of geometric In Line Inspection (ILI) intelligent tools with the inertial module is important for the diagnosis of structural integrity of pipelines and is associated with an integrity management program due to the geotechnical threats present throughout its path. It decreases maintenance costs due to pump stoppage for unscheduled repairs, anticipating the solution, and mitigating and controlling deformations in the pipeline caused by geotechnical ground displacements. OCENSA-Pipeline Central SA (Colombia) has developed, through its experience, a program to manage integrity by determining the structural expense in specific sections due to displacement of the pipeline caused by ground movement through the use of the Geometric ILI tools and MFL inertial module. This paper specifically presents the use of the tool in decision-making based on OCENSA’s preset study limits for deformations in the elastic range and plastic building material of the pipeline. In 1997 OCENSA was among the first companies in Latin America to use Inertial Geo-positioning technology; today there are sectors which have been inspected with this technology as many as five times, in which pipe displacement of up to 5 meters has been found. The case study presented refers to a geographical point on the route of the pipeline located in the Andes, at the site of the movement known as the “La negra” ravine, near the town of Puente Nacional, where movements of the pipeline associated with geotechnically unstable slope conditions were detected by In line inspection (ILI) Geometric and inertial modules, beginning in 2004. Since that time, integrity management was conducted in order to reduce the chances pipeline failure will materialize in this area of geotechnical instability.

Integrity Assessments

In 2000 and 2002, the US Department of Transportation’s Office of Pipeline Safety (OPS) published new regulations requiring integrity management programs for hazardous liquid pipeline operators. OPS had four fundamental objectives: 1) to increase the level of integrity assessments (i.e., in-line inspection or pressure testing) for pipelines that can affect high consequence areas; 2) to improve operator integrity management systems; 3) to improve government oversight of operator integrity management programs; and 4) to improve public assurance in pipeline safety. At the core of this new rule is a set of management-based requirements (referred to as “Program Elements” in the rule) that are fundamentally different from the existing, largely prescriptive pipeline safety requirements. The evaluation of operator compliance with these requirements requires the examination of management and analytical processes-aspects of operator’s business that are not reviewed in standard OPS compliance inspections. OPS realized a fundamentally different approach to oversight was needed to assure operators are developing and implementing effective integrity management programs. This paper describes the comprehensive changes to the OPS inspection program that were developed to perform integrity management inspections. OPS completed the initial integrity management inspection of all large hazardous liquid pipeline operators in early 2004, and is making progress in reviewing the programs of smaller liquid operators. During this initial year OPS gained substantial knowledge about the state of hazardous liquid pipeline operator integrity management programs. At a high level, OPS learned that operators generally understand what portions of their pipeline systems can affect high consequence areas, and are making the appropriate plans and progress in conducting integrity assessments for these areas. However, the development of effective management and analytical processes, and quality data and information to support these processes takes time. While most operators appear to be headed in the right direction, fundamental changes to management systems require time. OPS recognizes this situation and has developed an inspection and enforcement approach that not only assures compliance with the rule requirements, but also fosters continuous improvement in operator integrity management programs. This paper describes the lessons learned from the initial inspections, and OPS expectations for future integrity management program development. Finally, the intial year of integrity management inspections provided some valuable insights about how to perform these new type of inspections and improve external communication. This paper also addresses what OPS learned about its inspection program, and how this program is being positioned to support on-going inspections of hazardous liquid operator integrity management programs.

This paper presents a systematic and comprehensive procedure for the system-wide response to incidents (SWRI). This SWRI process has been used for identifying emerging threats and incorporating the learnings from major incidents into a pipeline integrity management program (IMP). This process also complements the IMP for threat identification and system wide risk assessment, thus giving consideration to all known threats and their interactions. A recent major incident due to thermal expansion on a TransCanada pipeline system was used to demonstrate the process of SWRI and the use of SWRI to identify the contributing factors of thermal expansion. An example was used to illustrate the engineering assessment for thermal expansion driven by the construction of two new compressor stations on an existing pipeline. The process documented in this case study has the potential to augment the integrity management programs and systemic corrective actions for pipeline systems in the energy industry.

Objective: This work aims to present to the Plan of Communications and Relationship with Communities implemented by TBG as a tool for the Bolivia-Brazil Pipeline integrity management. Scope: In studies carried out by the European Gas Pipeline Incident Data Group (EGIG), global statistics demonstrate that most accidents involving pipelines are caused by improper actions of third parties. The expansion of sugar cane crops and the improvements in utilities, such as telephone, electricity, water and sewage services in the cities along the pipeline have increased the number of events of interference in the right-of-way. These facts have evidenced the need for creating a Plan of Communications and Relationship with landowners and neighboring communities to assure the continuous monitoring of the Bolivia-Brazil Pipeline right-of-way. The Plan of Communications and Relationship with Communities is designed to reduce the risk of accidents caused by the improper action of third parties. The strategy of action is focused on strengthening the relationships among the right-of-way technical staff, TBG subcontractors, and other publics affected by the pipeline. It also encourages the use of the toll-free Gas Hotline (0800 026 0400) - TBG main communication channel with communities. The intensive publicity targeted at specific audiences ensures that local populations and other relevant publics raise their awareness on the importance of preserving the right-of-way, and the precautions that must be taken in their neighborhoods, mainly in cases of interferences, such as urban improvement projects and farming activities by keeping permanent contact with TBG through the Gas Hotline. This work will also present the interfaces among the right-of-way technical staff, the corporate communications team, and specific target audiences; communication resources, guidelines, technical training programs, Gas Hotline monitoring and management plans, indicators of services provided to the communities and landowners, and the results of the Gas Pipeline Management Program.

A Company

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.
