Most Common Pig Stuck Reasons in South Pars Pipelines

2018-10-10 | By: IPEC Co.

Pigs getting stuck in a pipeline is not a rare case during pipeline pre-commissioning operations. The real challenge is how to deal with it. The most common problems that usually happen in pipelines in South Pars Gas Field leading to pig stuck or stall conditions can be summarized as follows: - Collision of vessel anchors with pipeline and sticking to it, causing damage and buckling to the pipeline; - High length and low diameter (which…

Data analysis underpins successful pig rescue on small-diameter pipeline

2018-10-09 | By: Pooya Gholami

 The ability to pig a pipeline is crucial to maintenance and other operations such as pre-commissioning on the pipeline. Usually, high-length low-diameter pipelines are difficult to pig, and therefore produce a complicated pigging operation. There are several parameters that cause the pig(s) to get stuck. These include cleanliness of the pipeline; an accumulated amount of debris and corrosion product; pipeline dents or buckles; and erosion of pig disks. Recently, a pigging operation was performed in a…

Pipeline Cleaning, Mechanical and Chemical

2018-10-03 | By: Ali Sadedel

Cleaning a pipeline will increase pipeline flow efficiency by increasing the effective internal cross section area of the pipeline. Therefore the system can reach the nominal flow rate at lower pressures. There are two types of pipeline cleaning programs, mechanical and chemical. Mechanical cleaning is referred to running mechanical pigs along the route of the pipeline in order to remove debris from the pipeline. Most debris in the pipelines are located around 5 to 7'o…

Critical Considerations in Performing Offshore Projects

2017-10-02 | By: Pooya Gholami

When performing a sensitive high-risk offshore project, it is highly essential that all equipment and accessories be fully checked and prepared. In this matter, there are some major items that need to be taken under consideration. - All equipment and facilities should be checked and operated at onshore. - Full process circuit of each operational section of the project should once be run at onshore. - Each equipment should have a spare unit with the…
