Pipeline Crossings: Navigating Challenges in Midstream Engineering 

By Joe Pikas

The Evolution of Crossing Analysis

In 1983 a joint pipeline industry project with Batelle’s research using Spanglers work further illuminated the beneficial effects of various soil overburden configurations, providing invaluable insights into mitigating stress impacts on pipelines. The evolution of crossing analysis has been marked by significant milestones, notably the pioneering efforts of the Gas Technology Institute and subsequent advancements like the API 1102 in 1991. These developments laid the groundwork for understanding the stresses pipelines endure under wheel and track loads, especially in temporary and permanent crossings, and Technical Toolboxes was able to turn these insights into software for repeatable analysis.  

The Crossings Suite: An Integrated Approach

The Crossings Suite comprises a set of tools designed to address every phase of crossing management – from design and construction through operation, integrity, and record-keeping: 

Pipeline Toolbox 

The Pipeline Toolbox enriches the pipeline engineering landscape with its comprehensive array of modules, including Pipeline Crossings, Polyethylene Pipe, and HDD Lite modules. Designed for the multifaceted challenges of vehicle and equipment loads on buried pipelines and the specific needs of HDD projects, these tools are indispensable for engineers focusing on pipeline integrity. It supports both steel and polyethylene pipes across liquid and gas transportation, backed by over 230 calculations that comply with critical standards like PHMSA and ASME. The Pipeline Toolbox stands out for its lifecycle-wide utility, from design through to integrity, ensuring pipelines are not just compliant but also optimized for safety and efficiency. 

Crossings Workflow 

The Crossings Workflow module is a testament to the suite’s versatility, providing a streamlined process for simultaneously analyzing wheel and track load impacts on both steel and plastic pipelines. By incorporating historical data and leveraging advanced models, this tool ensures that all crossings are designed and validated to withstand the stresses of varying loads, thereby enhancing the safety and integrity of pipeline infrastructure. 

HDD PowerTool 

The Horizontal Directional Drilling (HDD) PowerTool is a game-changer for projects involving complex borehole designs. This module facilitates the planning and execution of HDD projects and provides critical analyses such as pull force and installation stress for polyethylene and steel pipes. With its many capabilities, the HDD PowerTool enables engineering teams to optimize borehole stability and minimize the risks associated with HDD installations. 

Streamlining Operations with Centralized Data Management 

At the core of the Crossings Suite’s efficiency is its centralized data management system. This system eliminates the need for repetitive manual data entry, reducing the potential for errors and saving valuable time. With all relevant data stored in a unified repository, teams can access and leverage this information across various applications within the suite, ensuring consistency and accuracy in analyses and reporting. 

Transforming Challenges into Opportunities

The Crossings Suite is more than just a software application; it’s a strategic asset that empowers engineering teams to tackle the most daunting crossing challenges with confidence. Whether it’s navigating the complexities of surface loading or optimizing borehole stability for HDD projects, the tool provides a robust platform for analysis and collaboration. 

In the realm of surface loading, the tool incorporates the latest theoretical models and analysis techniques to accurately predict the impacts of various loading scenarios. This capability is crucial for designing crossings that withstand the rigors of heavy loads while maintaining the structural integrity of the pipeline. 

The Road Ahead 

As we continuously refine and expand the functionalities of the Pipeline HUB and the Crossings Suite, our commitment to enhancing midstream operations remains unwavering. The challenges of pipeline crossings are diverse and evolving, but with the right tools and expertise, they can be transformed into opportunities for efficiency, safety, and operational excellence. 

By integrating tools like the Crossings Workflow and HDD PowerTool, along with centralized data management, the suite offers a comprehensive solution that meets the modern demands of midstream pipeline operations. 

For pipeline engineers and professionals seeking to learn and expand their crossings management strategies, the Crossings Suite offers a path forward. Explore the suite and discover how it can elevate your approach to managing pipeline crossings.
