Process Analytics secures the Quality of CO2 Pipeline Management

Process Analytics secures the Quality of CO2 Pipeline Management
Process Analytics secures the Quality of CO2 Pipeline Management
CO2 is a fundamental building block in the global decarbonization process. In order to successfully develop the individual processes for the separation of CO2 in the coming years, a reliable transport network, for example via pipelines, is a key issue. Here, process analytics plays an important role here to efficiently monitor and control the...

Digitalization of Pipeline Monitoring with Drones and AI at Thyssengas

Digitalization of Pipeline Monitoring with Drones and AI at Thyssengas
Digitalization of Pipeline Monitoring with Drones and AI at Thyssengas
Pipeline operators are obliged to regularly monitor their pipeline grid for potential third-party interferences (TPI). They need a reliable, cost-effective method to acquire and analyze aerial images of their pipeline in an automated process. This paper presents the concept of AIMI (Airborne Intelligent Monitoring of Infrastructures), a project...

Managing the Threat of Hard Spots in Gas Transmission Pipelines

Managing the Threat of Hard Spots in Gas Transmission Pipelines
Managing the Threat of Hard Spots in Gas Transmission Pipelines
Hard spots are a type of threat many operators are managing as part of their integrity management plan. Hard spots are areas on the pipeline that are more susceptible to cracking or could pose an integrity concern in combination with other threats. The United States gas transmission regulation, 49 CFR 192.3, defines a hard spot as “an area on steel...

Low-Cost Airborne Oil Leak and Threat Detection for Pipeline Right-of-Way

Low-Cost Airborne Oil Leak and Threat Detection for Pipeline Right-of-Way
Low-Cost Airborne Oil Leak and Threat Detection for Pipeline Right-of-Way
For years, pipeline operators have relied on human observers flying at low altitude to perform visual inspection of their ROW, without any automatic documentation or detection system. This paper presents the first real-life results of a test campaign performed by Flyscan Systems, integrating detection algorithms developed by Enbridge, over ROWs of...

The Influence of Anomaly Dimensions on POX for EMAT-C Crack Detection based on As Found Dig Results

The Influence of Anomaly Dimensions on POX for EMAT-C Crack Detection based on As Found Dig Results
The Influence of Anomaly Dimensions on POX for EMAT-C Crack Detection based on As Found Dig Results
In the context of repurposing of natural gas transmission pipelines to Hydrogen service the sensitivity of inspection systems with a focus on POX is frequently discussed. Often an increase of crack growth rate da/dN and a reduction in pipe steel toughness require a reduction of minimum remaining anomaly dimensions, in order to satisfy economically...

Integration of multiple Leak Detection Technologies into a single Advanced Leak Detection System
This work is centered on the integration of different Leak Detection Technologies into a single platform for a better management of Pipeline Integrity Monitoring issues. Leak detection methods covered in this paper are based on Advanced-Negative Pressure Wave, Mass-Balance, Acoustic-Noise, and other predictive techniques based on data processing...

Innovative Solutions to Address Stabilization Challenges of a 48-Year Old Subsea Pipeline

Innovative Solutions to Address Stabilization Challenges of a 48-Year Old Subsea Pipeline
Innovative Solutions to Address Stabilization Challenges of a 48-Year Old Subsea Pipeline
Subsea pipelines are externally concrete coated to provide vertical and lateral stability. The loss of concrete can lead to floatation or lateral movement on the seabed. If seabed is hard/rocky, then lateral rubbing may lead to wall thinning at 6 o'clock and can result in a leak or flattening at the bottom affecting ovality. This paper presents...

Security of Petroleum Pipelines in the Middle East

Security of Petroleum Pipelines in the Middle East
Security of Petroleum Pipelines in the Middle East
Oil pipelines in the Middle East have historically focused on the security of supply and export rather than on the economic benefits of having cheaper oil transport. Looking at the historical record of these pipelines, one could easily conclude that the objective of oil supply security sought by Middle-Eastern producers has not been met through...

Numerical prediction of material properties and structural response of JCO-E offshore pipes

University of Thessaly
University of Thessaly
The present paper presents the application of advanced finite element tools to predict the influence of cold-forming on material properties and collapse resistance of steel JCO-E pipes. Results are obtained for a thick-walled 30-inch-diameter pipe, corresponding to diameter-to-thickness ratio value less than 20. The numerical simulations are...

Offshore Pipelines and stability assessment of Submerged Slopes under Seismic Conditions

National Technical University of Athens
National Technical University of Athens
Depending on the prevailing bathymetrical and geotechnical conditions, the integrity of offshore pipelines is threatened by potential slope instabilities that occur at the seabed or at the bottom of lakes. In addition, submarine slides are more frequent in seismic regions. The instability of onshore slopes under seismic conditions is undoubtedly a...
