Transporting oil and gas through pipelines is a more reliable and environmentally friendly method compared to alternatives. However, pipelines come with some common risks for many reasons. Pipeline integrity and infrastructure have a complex pipeline network, making them critical to manage and examine. Also, a small pipeline mistake or negative impact on pipeline integrity can cause huge damage or even environmental accidents, affecting the whole operational efficiency of pipeline fracture. Understanding these common risk factors is crucial for operators to enhance safety, maintain compliance, and ensure uninterrupted service. Here are some of the most common risk factors in pipelines:

Corrosion

Corrosion is a common risk in pipelines which happens when they are exposed to the environment directly. Environmental factors like moisture, chemicals, or fluctuating temperatures affect the pipeline material. They can seriously compromise the pipeline's integrity. This can result in leaks, which pose environmental hazards and operational inefficiencies.

How to Control Corrosions?

1. Cathodic Protection: A technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. 2. Regular Inspections: Conduct frequent checks to identify and address corrosion early before it leads to significant damage. 3. Use of Corrosion-Resistant Materials: Selecting materials, such as certain alloys or coatings, that are less corrosion-prone when constructing or repairing pipelines.

Mechanical Damage

Damages caused by external factors like excavation activities, construction equipment, or accidental impacts are counted under mechanical damages. These activities affect the pipeline infrastructure, potentially damaging or compromising their structural integrity. Mechanical damage to a pipeline can result in immediate leaks, posing both safety hazards and high repair costs. Even when leaks don’t occur right away, the structural integrity of the pipeline is compromised, significantly increasing the risk of future failures.

How to Avoid Mechanical Damage?

1. Conduct detailed pipeline mapping: This ensures that pipeline locations are well-documented and can be avoided during excavation or construction activities. 2. Implement public awareness programs: Informing the public and workers about the presence of pipelines reduces the chances of accidental damage during external activities. 3. Use protective barriers: In high-risk areas where construction or excavation is common, installing protective barriers or markers around pipelines can provide an additional layer of safety.

Operational Errors

Human mistakes like test negligence, and misinterpreting readings, can occur during pipeline management. These errors can involve incorrect valve handling, accidental overpressurization, or poor maintenance practices. Even small errors in operation can introduce significant risks to the pipeline’s safety and performance. Operational errors can cause immediate pipeline failures, leading to leaks, ruptures, or other serious incidents. These failures can result in environmental harm, such as spills or contamination, and disrupt pipeline operations, affecting supply and increasing repair costs.

How to Mitigate Operational Errors:

1. Provide thorough training: Ensure pipeline operators receive comprehensive training on handling equipment, safety protocols, and emergency response procedures. 2. Automatic monitoring systems: Automated systems can detect potential issues like over-pressurization or improper valve operations, reducing human error and providing real-time feedback. 3. Strict protocols: Maintaining and strictly following established operational procedures minimises the risks associated with human error, ensuring pipelines are handled safely and efficiently.

Natural Disasters

Natural Calamities and extreme weather events cause critical risks to pipeline infrastructure. Pipelines are usually laid underground or in crucial areas that directly contact nature, allowing these disasters to affect pipelines. Damage caused by natural disasters increases the risk of displacement and ruptures. For example, earthquakes and landslides can move or shift parts of the pipeline. Extreme weather, like floods, can wash away the ground around it, making the pipeline weaker and more likely to leak.

How to Mitigate Natural Disasters

1. Disaster-resistant pipelines: Pipelines can survive disasters by incorporating stronger materials and flexible designs that can withstand seismic activity or extreme conditions. 2. Strategic route planning: Whenever possible, avoid placing pipelines in high-risk areas prone to natural disasters, such as earthquake fault lines or flood zones. 3. Develop contingency plans: Emergency response strategies should be in place to quickly address any issues resulting from a natural disaster, minimising damage and ensuring a swift recovery.

Third-Party Interference

Pipeline operators can easily monitor pipeline infrastructure within their premise parameters, but the pipeline network lies beyond their supervision, which increases the chance of pipeline risks. Interference by third parties is one of the common risks in pipelines. Such interference occurs when unauthorised individuals or organisations dig, construct, or even vandalise nearby pipeline infrastructure. These activities can unintentionally or intentionally damage pipelines, leading to operational risks and safety hazards. In more serious cases, intentional sabotage or vandalism could occur, posing a direct threat to the pipeline's safety and surrounding areas. These incidents can lead to environmental damage, operational shutdowns, and potential harm to nearby communities.

How to Mitigate Such Interference

1. Underground pipeline warning systems: Installing warning signs, markers, and barriers that indicate the presence of pipelines can deter unauthorised digging or construction. 2. Remote monitoring: Utilising real-time remote monitoring systems can detect suspicious activities near pipelines, allowing quick responses to prevent damage. 3. Public education campaigns: Informing the public, construction workers, and local businesses about pipelines' presence and risks helps reduce accidental interference. 4. Collaboration with local authorities: Partnering with local governments and law enforcement can ensure adequate oversight and prevent unauthorised activities around pipelines.

Ageing Infrastructure

Most pipelines were installed years ago; not all pipelines are newly built. So, pipeline ageing is one of the common risks in pipelines. Such older pipelines are more prone to corrosion and cracks. Also, degrading pipelines increases the risk of pipeline failures due to constant exposure to environmental factors and operational stress. These factors cause sudden breakdowns and expensive emergencies.

How to Mitigate Ageing Infrastructure

1. Regular inspections and maintenance: Frequent and proactive maintenance helps identify early signs of wear and tear. It allows us to perform timely repairs and prevent more significant issues. 2. Replace Older pipelines: Most of the pipelines will be older, but those that are at the end stage of the product cycle should be replaced with modern materials and designs more resistant to failure. 3. Using advanced technologies: Using advanced analytics allow pipeline operators to monitor in real-time and check their condition to predict potential issues before they occur.
