In total, Halvorsen delivered six pigging receiving stations in 2019.<\/p>\n
\u2013 Six \u00abpig receivers\u00bb in one year is an unusually large number, says John Vester Nielsen, head of fabrication at Halvorsen.<\/p>\n
In the oil industry, \u00abpigging\u00bb is a term for a pipe-cleaning process. Brushes are inserted into the pipe and pushed along the pipeline to clean out rust, wax, and debris. The scraping sound that occurs during the process can resemble a squealing pig \u2013 hence the name \u00abpigging\u00bb.<\/p>\n
The brush is placed in a \u00abpig launcher,\u00bb which is a type of launch station, and is then pushed down the pipe until it reaches the receiving station \u2013 the so-called \u00abpig receiver.\u00bb.<\/p>\n
\u2013 We started work on the last two \u00abreceivers\u00bb in July. There are high quality requirements for the welding. We\u2019re talking about a product with a thickness of between 20 and 30 millimetres, so the job is demanding. But the result has been very good, says Nielsen.<\/p>\n
\u00abPigging\u00bb has been used for many years to clean large offshore pipelines. However, it is becoming increasingly common in smaller diameter pipelines as operators seek increased efficiency and reduced costs.<\/p>","protected":false},"excerpt":{"rendered":"
