Removal of liquids from gas pipelines is crucial for maintaining pipeline integrity. The liquids are a potential corrosion threat as well as having flow assurance implications if the quantity of liquid in the pipeline becomes excessive for handling at receipt. There is therefore a high importance on optimisation of sphering strategies for maintaining operability of pipeline systems whilst minimising the number of sphering operations required.
However in the water and waste water industry pipelines consists of other materials than steel. Normally PVC, HDPE, asbestos cement, cast iron and concrete lined steel pipes are used, which need another approach to determine its integrity. For these types of materials the degradation system is not fully known yet and other parameter than the remaining wall thickness could be important.
A. Hak Industrial Services has started a trial and error approach. Together with the water and wastewater industry some critical pipeline types were identified and were inspected using the existing ultrasonic Piglet technology.
In an ideal world, construction of offshore pipelines should be completed without any incidents. However, in the real world, and for a variety of reasons, sections of a pipeline can sometimes become damaged or even flooded during the laying process. Such an occurrence of unplanned flooding of the pipeline is known as “wet-buckling”. Since a pipeline is most likely to buckle during deepwater installation, it is important to have detection and correction methods in place at this stage.
