The UK firm supplied the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform positioned in the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because sodium hypochlorite is extremely corrosive, Amarinth originally used titanium alloy for all wetted parts.
During a routine capital assessment, ADNOC determined the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are crucial to manufacturing and refurbishment needed to align precisely with a selected shutdown schedule.
The shutdown schedule would not permit the pumps to be returned to the UK for a full strip, assessment and refurbishment, so Amarinth used its UAE facility to undertake the work.
Amarinth’s UAE facility was able to full the strip and evaluation report within 5 working days and suggest two refurbishment projects. The first concerned a full rebuild, check and warranty of the primary pump changing all the titanium components including impeller, shaft, bearing brackets and mechanical seals. The work needed to be completed in just eight weeks. เพรสเชอร์เกจ4นิ้ว prioritised the ordering of the titanium elements and was able to have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second venture undertook the same work on the opposite two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, stated: “Having equipped the original pumps to ADNOC we’ve a wealth of experience in working with titanium components. We are also pleased with the expansion of our local UAE facility for service and assist and which enabled us to successfully expediate this specific refurbishment, benefiting both ADNOC and the local financial system.”
