📝How Terrain Influences Liquid Accumulation in Pipelines

/

When designing and operating long-distance pipelines, terrain elevation is one of the most overlooked yet critical factors in liquid accumulation and flow assurance. In undulating landscapes, valleys, hills, and dips create gravity-induced traps where liquids such as water, condensate, or oil can settle—leading to slugging, corrosion, and pressure imbalances. In this post, we’ll explain how

📝How to Choose the Right Wall Thickness for Your Pipeline

/

Pipeline wall thickness is one of the most critical decisions in pipeline design. It directly affects the pipe’s ability to withstand internal pressure, environmental loads, and long-term corrosion. Selecting the wrong wall thickness can lead to overdesign (and excess cost) or, worse, underdesign — increasing the risk of failure. In this post, we’ll explain the

🧠 How to Assess the Integrity of an Unpiggable Subsea Pipeline

/

🔍 What Is an Unpiggable Pipeline? An unpiggable pipeline is one that cannot accommodate traditional pigs due to design or access constraints. This is common in: ⚠️ Key Risk: Without inline inspection, you may be blind to corrosion, deposits, or damage building up inside. 🛠️ How Can You Assess Them Without Pigging? ✅ 1. External

📝Understanding Slugging in Multiphase Pipelines: Causes, Risks & Solutions

/

Slugging is a common and often disruptive phenomenon in multiphase pipeline systems, where gas and liquid phases do not flow uniformly. Instead, they form alternating slugs of liquid and gas that can surge unpredictably through the line — causing pressure fluctuations, flow instability, and equipment stress. In this post, we break down what causes slugging,

🔍 What Is MAOP and How Do You Calculate It Correctly?

/

🚧 What Is MAOP? Maximum Allowable Operating Pressure (MAOP) is the highest pressure at which a pipeline can safely operate under regulated conditions. Determining the MAOP is critical to ensure safe operation, avoid failure, and comply with design codes such as ASME B31.8 or ASME B31.4. Improper MAOP settings can lead to pipeline ruptures, fines,

Pipeline pigging

📝How to Select the Right Pipeline Pigging Strategy for Your Operation

/

Pipeline pigging is a critical operation in maintaining the integrity and efficiency of oil and gas pipelines. Yet many engineers still rely on outdated or generalized strategies without considering pipeline-specific characteristics. In this post, we’ll explore how to select the most effective pigging strategy based on key factors like flow conditions, debris levels, pig types,

📝The Role of Design Codes in MAOP Calculations – B31.4 vs B31.8 vs ISO 13623

/

The Maximum Allowable Operating Pressure (MAOP) is a fundamental parameter in pipeline design and integrity assessment. It determines the highest pressure a pipeline can safely operate under normal conditions, and its calculation is governed by design codes tailored to the type of fluid transported and regional regulations. In this article, we’ll compare three widely used

📝Optimizing Inspection Intervals Using Risk-Based Tools

/

In pipeline integrity management, inspections are essential — but when and how often you perform them can make or break your operation’s safety and cost-efficiency. Risk-Based Inspection (RBI) tools offer a smarter, data-driven approach to schedule inspections, focusing resources where they are needed most while avoiding unnecessary downtime. This blog post explores how to determine

📝Why Flowline Insulation Design Is Critical in Offshore Pipelines

/

Flowline insulation plays a vital role in offshore pipeline systems, particularly in deepwater operations where temperature and pressure differentials are extreme. The right insulation strategy ensures flow assurance, prevents hydrate and wax formation, and reduces the need for chemical injection or intervention. In this article, we explore why flowline insulation is essential, how it’s designed,

📝Understanding Pipeline Downtime Costs and How to Minimize Them

/

Pipeline downtime — whether due to planned maintenance, inspection, or unexpected failure — can have significant financial consequences. For oil, gas, and multiphase transport systems, every hour offline represents lost revenue, additional resource costs, and potential penalties or environmental risks. In this article, we explore what makes downtime so costly and what engineers and asset

Top 5 Causes of Flow Assurance Failures – and How to Prevent Them

/

Flow assurance is a critical discipline in pipeline engineering, especially for offshore and long-distance pipelines carrying complex fluid mixtures. A single oversight can lead to severe downtime, safety hazards, and millions in operational losses. Below are the five most common causes of flow assurance failures—and how to prevent them using practical engineering tools. 1. Hydrate

📝Emulsions and Slugging: Complicating Separation

/

In oil and gas production, the path from reservoir to market is far from smooth. Two major flow assurance challenges — emulsions and slugging — frequently complicate fluid handling and downstream separation. Left unmanaged, they can cause processing inefficiencies, equipment damage, and unplanned shutdowns. This post explores how emulsions and slug flow occur, why they’re

Corrosion Under Insulation (CUI): The Hidden Threat to Pipeline Integrity

/

Corrosion under insulation (CUI) is one of the most deceptive and damaging forms of corrosion affecting industrial pipelines and process systems. Unlike external corrosion which is typically visible, CUI occurs beneath thermal insulation, making it difficult to detect until significant degradation has occurred. 🔍 What Causes CUI? CUI typically arises when moisture penetrates the insulation
