The Problem We Aim to Solve

"Stress Corrosion Cracking (SCC) has been a significant concern for pipeline integrity since the mid-1960s, often leading to devastating failures over time. Traditional pipeline management methods have been limited to just three options, constrained by the interplay of three key variables that contribute to the onset and propagation of SCC in pipeline steels".

 

Our Approach

Managing this pervasive threat (SCC)has long been restricted to three techniques: Hydrotesting, In-Line Inspection (ILI), and Direct Assessment (DA). Each of these methods is influenced by various factors including pipe characteristics, manufacturing processes, operational histories, and available historical data.

Big Data's Role

The term "Big Data" refers to the massive volume of structured and unstructured data that is too large to be processed using traditional database and software techniques. In the context of pipeline management and, more specifically, in the study and mitigation of Stress Corrosion Cracking (SCC), Big Data plays a crucial role. It can provide unprecedented insights into the intricate relationships between mechanical stress, material properties of the pipe, and the environmental conditions surrounding it.

The Triad of Variables

Understanding SCC involves three main variables:

Mechanical Stress on Pipeline 

Mechanical stress on pipelines can arise from various sources such as internal pressure, temperature fluctuations, soil movements, and even tectonic activity. Over time, this stress can cause micro-cracks to form in the pipeline material, which may eventually evolve into more significant stress corrosion cracking (SCC).

Material Characteristics of the pipe

The material makeup of the pipeline, including the type of steel, coating material, and even the quality of welds, plays a crucial role in its susceptibility to SCC. Factors like tensile strength, ductility, and hardness are all vital characteristics.

Environmental Conditions surrounding the pipeline

The soil and environmental conditions in which a pipeline is buried significantly affect its integrity. Parameters such as soil moisture, pH level, and temperature fluctuations are crucial factors.
