Baku-Tbilisi-Ceyhan Oil Pipeline Pumps Reconditioned by Amarinth
Amarinth, a leading manufacturer of pumps for a variety of applications, has completed its reconditioning of pumps stationed on the Baku-Tbilisi-Ceyhan pipeline.The updated pumps will safeguard against pollution in a region of Georgia that exports natural spring water.
At 1,768 kilometers, the Baku-Tbilisi-Ceyhan pipeline is the second longest in the world. It carries oil from Baku in Azerbaijan to Ceyhan on Turkey’s Mediterranean coast. Since 2006, the pipeline has delivered one million barrels of crude oil each day, while crossing environmentally sensitive regions in Georgia where natural spring water is produced. To prevent pollution, sumps were constructed at the base of the valley. Amarinth previously installed API 610 VS4 vertical pumps, so if the pipeline had to be drained, the sump would contain the pipe volume of oil. It would then be pumped out and disposed of in an environmentally sensitive manner.
During scheduled maintenance, one of the vertical pumps was run dry, ingested debris, and the impeller seized. The pipeline operator contacted Amarinth in order to assess the damage. Because of the possible environmental impact from pollution, the pump manufacturer was given just three weeks to complete any work and re-commission the pumps.
“We were very pleased to be able to assist BP with the repair and re-commissioning of these strategically important pumps on the Baku-Tbilisi-Ceyhan pipeline,” says Oliver Brigginshaw, Managing Director of Amarinth.
After arriving on-site, Amarinth lifted the pump and found that the damage was much worse than anticipated. In addition, further issues were identified with the impeller. Despite the extent of the damage, with its agile operations and ability to place skilled engineers anywhere in the world, Amarinth was able to rebuild and re-commission the damaged pump within the three-week timeframe.
After the repair, Amarinth suggested glycol be used in the sumps, so that the pumps could be run every six months without the danger of dry running. The pump manufacturer also drew up a spares list so future issues could be addressed swiftly.
